Americans with Disabilities Act (ADA) Accessibility Guidelines 
for Buildings and Facilities; Architectural Barriers Act (ABA) 
Accessibility Guidelines

AGENCY: Architectural and Transportation Barriers Compliance Board.

ACTION: Notice of Proposed Rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Architectural and Transportation Barriers Compliance Board 
(Access Board) is proposing to revise and update its accessibility 
guidelines for buildings and facilities covered by the Americans with 
Disabilities Act of 1990 (ADA) and the Architectural Barriers Act of 
1968 (ABA). These guidelines cover new construction and alterations and 
serve as the basis for enforceable standards issued by other Federal 
agencies. As a result of this revision and update, the guidelines for 
the ADA and ABA are consolidated in one Code of Federal Regulations 
part. The guidelines for the ABA also cover buildings and facilities 
leased by Federal agencies. The Department of Justice and the 
Department of Transportation are responsible for issuing standards 
based on the Access Board's guidelines under the ADA. ABA standards are 
issued by the Department of Defense, General Services Administration, 
the Department of Housing and Urban Development, and the U.S. Postal 
Service.

DATES: Comments should be received by March 15, 2000. The Access Board 
will hold two public hearings on the proposed guidelines. The dates, 
times, and locations of the public hearings will be published in a 
subsequent document in the Federal Register.

ADDRESSES: Comments should be sent to the Office of Technical and 
Information Services, Architectural and Transportation Barriers 
Compliance Board, 1331 F Street, NW., suite 1000, Washington, DC 20004-
1111. Fax number (202) 272-5447. E-mail comments should be sent to 
docket@access-board.gov. Comments sent by e-mail will be considered 
only if they include the full name and address of the sender in the 
text. Comments will be available for inspection at the above address 
from 9:00 a.m. to 5:00 p.m. on regular business days.

Statutory Background

    The Americans with Disabilities Act of 1990 (ADA) (42 U.S.C. 12101 
et seq.) recognizes and protects the civil rights of people with 
disabilities and is modeled after earlier landmark laws prohibiting 
discrimination on the basis of race and gender. The ADA requires that 
buildings and facilities be accessible to and usable by people with 
disabilities. The ADA establishes accessibility requirements for new 
construction and alterations of State and local government facilities 
under title II and places of public accommodation and commercial 
facilities under title III. The law requires that the Access Board 
issue minimum guidelines to assist the Department of Justice (DOJ) and 
the Department of Transportation (DOT) in establishing accessibility 
standards under titles II and III. These standards must be consistent 
with the Access Board's guidelines.
    The Architectural Barriers Act of 1968 (ABA) (42 U.S.C. 4151 et 
seq.) requires that facilities designed, built, altered or leased with 
certain Federal funds be accessible to persons with disabilities. 
Similar to its responsibility under the ADA, the Access Board is 
charged with developing and maintaining minimum guidelines for 
accessible facilities that serve as the basis for enforceable standards 
issued by four standard-setting agencies. The standard-setting agencies 
are the Department of Defense (DOD), the General Services 
Administration (GSA), the Department of Housing and Urban Development 
(HUD), and the U.S. Postal Service (USPS).

Rulemaking History

    On July 26, 1991, the Access Board published the Americans with 
Disabilities Act Accessibility Guidelines (ADAAG).<SUP>1</SUP> On the 
same day, the Department of Justice published its final regulations 
implementing title III of the ADA which incorporated ADAAG.<SUP>2</SUP> 
The Access Board amended ADAAG to include additional requirements 
specifically applicable to transportation facilities on September 6, 
1991 <SUP>3</SUP> which DOT incorporated into its final ADA 
regulations.<SUP>4</SUP> The Access Board modified ADAAG, and DOJ and 
DOT modified their standards on two occasions: to revise specifications 
for automatic teller machines (July 15, 1993) and to suspend 
requirements for detectable warnings at curb ramps, hazardous vehicular 
areas, and reflecting pools (April 12, 1994; July 29, 1996; November 
23, 1998).<SUP>5</SUP>

    The Access Board published amendments to ADAAG on January 13, 1998, 
that cover State and local government facilities and building elements 
designed for children's use.<SUP>6</SUP> The amendments for State and 
local government facilities add a section on judicial, legislative, and 
regulatory facilities which covers access to restricted and secured 
entrances, security systems, assembly seating, speakers' platforms, and 
to courtroom spaces. Another section covers detention and correctional 
facilities which provides scoping and technical requirements for 
accessible cells. In addition to these two new sections, ADAAG was 
amended to address elevators, entrances, TTYs, sales and service 
counters, and airport security systems in State and local government 
facilities. As originally published, ADAAG provided specifications 
based only on adult dimensions. The

[[Page 62249]]

amendments for building elements designed for children's use provide 
alternate specifications based on children's dimensions for drinking 
fountains, water closets, toilet stalls, lavatories and sinks, and 
built-in seating and tables. The technical requirements permit 
departures from existing ADAAG specifications for elements designed for 
use primarily by children instead of adults.

    In 1994, the Board established an advisory committee to conduct a 
complete review of the guidelines and to recommend changes. The ADAAG 
Review Advisory Committee consisted of 22 members representing the 
design and construction industry, the building code community, State 
and local government entities, and people with 
disabilities.<SUP>7</SUP> The committee was charged with reviewing 
ADAAG in its entirety and making recommendations to the Board on:

    <bullet> improving the format and usability of ADAAG;
    <bullet> reconciling differences between ADAAG and national 
consensus standards, including model codes and industry standards;
    <bullet> updating ADAAG to reflect technological developments and 
to continue to meet the needs of persons with disabilities; and
    <bullet> coordinating future ADAAG revisions with national 
standards and model code organizations.
    The advisory committee organized itself into subcommittees and met 
extensively over a two year period. Non-members were invited to 
participate in subcommittee meetings. The advisory committee followed a 
consensus-based process for the adoption of recommended changes to 
ADAAG which included a process for the submission of dissenting 
opinions. The advisory committee's work culminated in publication of a 
final report, ``Recommendations for a New ADAAG'' (September, 1996), 
which is available from the Board. Vice President Albert Gore 
recognized the work of the advisory committee and its constructive 
relationship with the Board and presented both entities with his 
``Hammer Award'' which recognizes exemplary reinvention of the Federal 
government. The award commended the manner in which a variety of public 
and private sector interests were brought together to update the 
guidelines. The advisory committee's report recommends changes to both 
the format and substance of ADAAG.
    The Board developed minimum guidelines for federally funded 
facilities covered by the ABA in 1982 that served as the basis for the 
Uniform Federal Accessibility Standards (UFAS). To further the goal of 
uniform standards, the Board is proposing to update these minimum 
guidelines based on the revisions to ADAAG. This will establish 
consistency between both guidelines so that the public and private 
sectors are held to a similar level of accessibility. This will 
facilitate compliance where a facility is subject to both the ADA and 
the ABA, such as a State or local government facility built with 
Federal money.
    The Board's minimum guidelines do not directly impact the public. 
Instead they provide a minimum baseline for other Federal departments 
responsible for issuing enforceable standards. Each Federal department 
responsible for issuing and maintaining standards based on the Board's 
guidelines under the ADA or the ABA is represented on the Board. 
Representatives of these departments serve as Board members and staff 
liaisons and have been closely involved in the development of this 
proposed rule. Through this process, the Board and the standard-setting 
agencies coordinated extensively to seek consensus to minimize any 
differences between the Board's guidelines and their eventual 
standards.

General Issues

    The ADAAG Review Advisory Committee recommended significant changes 
to the format and style of ADAAG. In fact, their recommendations 
completely reorganize much of ADAAG. The changes were recommended to 
provide a guideline that is organized and written in a manner that can 
be more readily understood, interpreted and applied. The recommended 
changes would also make the arrangement and format of ADAAG more 
consistent with model building codes and industry standards. This will 
make it easier for designers of the many facilities that will be 
required to comply both with the ADAAG and the locally adopted codes to 
understand how to comply with both sets of provisions. Changes include:
    <bullet> removal of text language that is non-mandatory in nature 
for inclusion as advisory information nearby the text it comments on;
    <bullet> inclusion in written text of requirements otherwise 
provided only in figures;
    <bullet> clearer delineation between scoping requirements, which 
indicate what has to be accessible, from technical requirements, which 
specify how access is to be achieved;
    <bullet> organizing technical sections into chapters according to 
the type of element or space;
    <bullet> streamlining the guidelines by integrating special 
occupancy chapters (except for transportation facilities) into the main 
body of the document;
    <bullet> revising the substance of scoping and technical provisions 
to better meet the needs of people with disabilities, to recognize 
technological developments, and to reconcile differences from national 
consensus standards; and
    <bullet> utilizing a decimal-based, numeric-only numbering system, 
consistent with that used by the model codes and utilizing, to the 
extent possible, identical chapter and section numbers as ICC/ANSI 
A117.1 for the comparable subject matter.
    Some changes are recommended in order to make the provisions in 
ADAAG more technically consistent with model building codes and 
industry standards. The advisory committee coordinated closely with the 
American National Standards Institute (ANSI) A117 Committee, which was 
in the process of updating its standard. This is a national consensus 
standard that provides technical requirements for accessible buildings 
and facilities. The Council of American Building Officials (CABO) was 
represented on the advisory committee. CABO, which functions as a 
coordinating body among model code organizations, serves as the 
Secretariat for the A117 Committee. CABO has been incorporated into the 
International Codes Council (ICC). While ADAAG requirements derive in 
large part from an earlier version of the ANSI standard, there are 
considerable differences between them. Both the advisory committee and 
the ANSI committee sought to reconcile these differences to harmonize 
the revised ADAAG with the ICC/ANSI A117.1-1998 standard.
    The Board reviewed all recommendations from the advisory committee 
and has adopted most of them with some changes of its own. In addition, 
the Board has developed new figures to illustrate various provisions 
and provided new advisory notes that

[[Page 62250]]

provide information currently contained in the appendix to ADAAG. In 
removing non-mandatory information from the text of the guidelines, the 
advisory committee made various recommendations on information that 
should be included in advisory notes. The Board has taken these 
recommendations into account in developing advisory notes for this 
proposed rule.
    The application and scoping requirements (Chapters 1 and 2) for 
facilities covered by the ADA have been used as the basis for updating 
application and scoping requirements for facilities subject to the ABA. 
The technical requirements of this rule, as revised according to the 
advisory committee recommendations, are referenced by both scoping 
documents.
    In addition, the Board has included scoping and technical 
requirements for accessible residential facilities. These requirements 
are based on updated provisions for residential facilities contained in 
the ICC/ANSI A117.1-1998 standard. These requirements represent an 
addition to ADAAG, which currently does not address such facilities. 
Also, they will serve to update requirements for dwelling units in the 
minimum guidelines for federally funded facilities upon which UFAS is 
based.

Section-by-Section Analysis

    The following discussion covers the three parts of this rule. Part 
I covers the application and scoping requirements for facilities 
covered by the ADA (Chapters 1 and 2). This section of the analysis 
explains substantive differences between the revised guidelines and the 
current ADAAG. All changes proposed are based on recommendations from 
the advisory committee unless otherwise noted. Part II addresses the 
application and scoping requirements for facilities covered by the ABA. 
This section explains changes from the scoping and application 
requirements of Part I that are specific to federally funded 
facilities. Part III discusses the technical requirements (Chapters 3 
through 11) that are referenced by both ADA and ABA scoping documents. 
These requirements are based on recommendations from the advisory 
committee. As in Part I, the discussion in Part III explains 
substantive differences between the current ADAAG and the revised 
guidelines. The Board has posed a number of questions in this section. 
The Board includes questions in the preamble usually because it wants 
to solicit additional information about an item before considering a 
specific requirement.

Part I: ADA Application and Scoping

Chapter 1: Application and Administration
    This chapter states general principles that recognize the purpose 
of the guidelines (101), provisions for adults and children (102), 
equivalent facilitation (103), conventions (104), referenced standards 
(105), and definitions (106). Chapter 1 simplifies and reorganizes 
similar provisions contained in ADAAG sections 1, 2, and 3.
    The Board has removed the term ``fixed'' in the revised guidelines 
for editorial purposes of clarity and consistency. The term is used in 
the current ADAAG to describe some elements, such as tables and 
storage, but not other types of covered elements. The Board understands 
that DOJ will clarify the application of the guidelines to fixed 
elements in its rulemaking to update its standards for consistency with 
the revised guidelines.

104  Conventions

    Section 104.1 notes that all dimensions not stated as a ``maximum'' 
or ``minimum'' are absolute. All dimensions, including absolute 
dimensions, are ``subject to conventional industry tolerances.'' This 
corresponds with provisions in ADAAG 3.1 and 3.2 for graphic 
conventions and dimensional tolerances except for one change. ADAAG 3.2 
recognizes conventional building industry tolerances ``for field 
conditions.'' The reference to ``field conditions'' has been removed to 
accommodate a wider variety of unavoidable tolerances other than those 
that occur on a construction site, namely manufacturing processes that 
are not true ``field'' situations. For example, acrylic molded plumbing 
fixtures, such as shower stalls, often have a slight draft or taper so 
that they can be drawn from their molds; this slight taper does not 
adversely affect accessibility and is a necessary consequence of this 
particular manufacturing process. ``Conventional industry tolerances'' 
is intended to refer to tolerances in construction and manufacturing, 
but not design.
    The Board has clarified the calculation of percentages in section 
104.2. This provision states that one is to round up to the next whole 
number when calculating ratios or percentages in determining the 
minimum number of required accessible elements or facilities. Where the 
required size or dimension of an element or facilities involves ratios 
or percentages, rounding down for values less than one half is 
permitted.

105  Referenced Standards

    Section 105 lists the industry standards referenced in the 
guidelines. It also clarifies that where there is a difference between 
a provision of the guidelines and the referenced standards, the 
provision of the guidelines shall apply.

106  Definitions

    Various defined terms and definitions have been revised, removed or 
added. The following definitions have been removed because they contain 
information more appropriately covered in technical requirements or are 
not considered necessary due to other text changes: ``access aisle,'' 
``accessible element,'' ``accessible space,'' ``adaptability,'' 
``clear,'' ``clear floor space,'' ``multi-family dwelling,'' and ``site 
improvement.'' Several definitions have been simplified by removing 
information contained in scoping or technical requirements or have been 
revised for consistency with model code definitions. These include: 
``accessible route,'' ``automatic door,'' ``area of rescue 
assistance,'' ``controls and operating mechanisms'' (which have been 
changed to ``area of refuge'' and ``operable parts,'' respectively), 
``dwelling unit,'' ``facility,'' ``means of egress,'' ``occupiable,'' 
``sign,'' ``story,'' and ``transient lodging.'' Defined terms added to 
this section include: ``characters,'' ``children's use,'' 
``destination-oriented elevator,'' ``employee work areas,'' ``mail 
boxes,'' ``pictogram,'' ``project,'' ``public entrance,'' ``qualified 
historic building or facility,'' ``self-service storage facility,'' 
``technically infeasible,'' ``wheelchair,'' and ``wheelchair space.''
Chapter 2: Scoping Requirements
    This chapter provides scoping requirements for spaces and elements 
required to be accessible in new construction and alterations. Chapter 
2 replaces the minimum requirements sections of ADAAG 4.1. As revised, 
this section of the guidelines differs from ADAAG in that it integrates 
the scoping for exterior sites and interior facilities. ADAAG addresses 
scoping for exterior sites and interior facilities in separate 
subsections (4.1.2 and 4.1.3, respectively). ADAAG also currently has 
some scoping provisions intermingled with various technical provisions 
outside of 4.1. All scoping provisions are now located in Chapter 2.

201  Application

    This section contains provisions for the general scope of the 
guidelines and is substantively consistent with

[[Page 62251]]

application provisions in ADAAG 4.1.1(1), (2), and (4).

202  Existing Buildings and Facilities

    This section provides for the application of the guidelines to 
additions and alterations. Section 202.2 (Additions) clarifies the 
intent in ADAAG 4.1.5 that each addition meet the requirements of the 
guidelines for new construction and also refers to requirements for 
additions that affect or could affect areas containing a primary 
function.
    Section 202.3 contains general scoping requirements for 
alterations, which are currently addressed in ADAAG 4.1.6(1). 
Alterations scoping provisions and technical provisions specific to 
certain elements and spaces in ADAAG 4.1.6(1) and 4.1.6(3) are not 
included in this general application section. Instead these provisions 
have been relocated to the relevant scoping or technical provisions for 
the element or space. Many of these provisions in ADAAG provide 
alternate specifications where ``technical infeasibility'' is 
encountered. However, these specifications present a false ``cap'' to 
the degree of departure since compliance is actually required to the 
degree it is technically feasible which may be above or below the level 
of access recognized in the specification. Consequently, in the revised 
guidelines, alternate criteria that have been retained have been made 
applicable to alterations generally and are not limited to instances of 
technical infeasibility.
    As revised, the guidelines do not contain the provision currently 
in ADAAG 4.1.6(1)(c) which requires an entire space to be accessible 
when alterations of single elements, considered together, amount to an 
alteration of a room or space. The advisory committee considered this 
provision vague and difficult to enforce since it does not indicate the 
precise number of altered single elements that would trigger full 
compliance for a room or space. In view of the basic scoping 
requirements for alterations, the Board agrees this provision can be 
removed without affecting accessibility.
    Section 202.4 addresses requirements for alterations affecting 
primary function areas that are consistent with those in ADAAG 4.1.6(2) 
except for one change. ADAAG 4.1.6 (1)(i) clarifies that the 
requirement does not apply to work limited solely to electrical, 
mechanical, or plumbing systems; hazardous material abatement; or 
automatic sprinkler retrofitting if the work does not involve 
alteration of elements or spaces required to be accessible. While the 
advisory committee did not recommend removing this clarification, the 
Board has removed it as information more appropriately contained in the 
Department of Justice's (DOJ) implementing regulations. The DOJ 
regulations further address alterations to areas containing a primary 
function, including the type of alterations that trigger the 
requirement for an accessible path of travel.<SUP>8</SUP>
---------------------------------------------------------------------------

    \8\ 28 CFR 36.403.
---------------------------------------------------------------------------

    Section 202.5 clarifies that scoping for alterations, including 
alterations to areas containing a primary function, applies to 
qualified historic buildings and facilities, but permits an exception 
where such alterations would threaten or destroy the historic 
significance of the building or facility as determined by the State 
Historic Preservation Officer or Advisory Council on Historic 
Preservation. This simplifies ADAAG 4.1.7 and removes advisory 
information from the text of the requirement. Special provisions for 
specific elements and spaces in ADAAG 4.1.7(3) have been moved to 
appropriate scoping and technical requirements in the revised 
guidelines.

203  General Exceptions

    The structure of the revised guidelines reinforces the principle 
that under the general scoping, all portions of sites and facilities 
are subject to the guidelines unless otherwise noted. This section 
contains exceptions to the general scoping provisions in 201. Most 
provisions are substantively the same as those in ADAAG 4.1.1(5) as 
amended for State and local government buildings, including those 
addressing construction sites (203.2), raised areas (203.4), limited 
access spaces (203.5), equipment spaces (203.6), single occupant 
structures (203.7), and detention and correctional facilities (203.8).
    There are two substantive changes involving the ``structural 
impracticability'' exception and residential facilities (203.9). ADAAG 
4.1.1(5)(a) provides an exception for new construction where it can be 
demonstrated that full compliance is ``structurally impracticable'' due 
to rare circumstances or the uniqueness of the terrain. The advisory 
committee recommended removing this exception because it felt that the 
challenges posed by unique environmental or terrain features can be 
overcome by good design. Further, such an exception is not recognized 
by any of the model building codes. Despite the fact that the exception 
for ``structural impracticability'' has been removed from ADAAG, it 
still exists in the Department of Justice (DOJ) implementing 
regulations. See 28 CFR 36.401(c). The term is defined in that same 
section and provides a narrowly drawn exception for ``unique 
characteristics of terrain.'' It was removed from ADAAG because the 
Board made every effort not to duplicate provisions that are in the DOJ 
regulations. The revised guidelines also include an exception in 203.9 
under which access is not required to common use areas that do not 
serve dwelling units required to be accessible.

203.3  Employee Work Areas

    ADAAG 4.1.1(3) requires access to, but not fully within, employee 
work areas in part because title I of the ADA generally treats access 
for employees with disabilities as an individual accommodation. The 
Board intends the word ``employee'' in the term employee work areas to 
include individuals covered in the definition of employee found in 
title I of the ADA, as well as other individuals who perform employee-
type duties such as independent contractors and volunteers. Employee 
spaces used for purposes other than job-related tasks, such as break 
rooms, lounges, and locker rooms are not considered ``work areas'' and 
must be fully accessible. Other areas that must be fully accessible 
include, but are not limited to, vending areas, cafeterias, and 
auditoriums regardless of whether they are restricted to employees. 
Work areas that also function as public use space, such as patient exam 
rooms, must be fully accessible for public access, but fixtures and 
controls within the work area used only by employees are not required 
to be accessible.
    Section 203.3 of the revised guidelines retains this exception for 
areas used only as work areas. Work areas must be accessible for 
``approach, entry, and exit,'' which means location on an accessible 
route so that people with disabilities can enter and exit the space. 
The Board interprets this provision as requiring an accessible route to 
work areas, including complying entry doors or gates. Maneuvering 
space, including wheelchair turning space, is not required within the 
work area, and elements within the work area are not required to 
comply. Also, the Board has added a definition for ``employee work 
areas'' in section 106 to clarify the limited application of this 
provision.
    The coverage of ``employee work areas'' in section 203.3, like 
ADAAG 4.1.1(3), means that an accessible route is not required to 
individual work stations within the area. For example,

[[Page 62252]]

an accessible route is required to a restaurant kitchen or the 
manufacturing space of a plant but not to individual work stations, 
regardless of the number of stations or the size of the work area. The 
advisory committee recommended that ADAAG be changed to require an 
accessible route to each ``individual work station'' instead of to 
``work areas.'' Other than the connecting route, work stations would 
not be required to be accessible. The advisory committee recommended 
this change for consistency with model building codes which, unlike 
ADAAG, do not provide a similar exception for work areas. The advisory 
committee considered that contemporary building and fire codes, for 
general fire and life safety purposes, have always required in new 
construction and alterations that a path of travel serving individual 
work stations be provided for exiting in an emergency. In complying 
with the code, this path of travel would end up complying with most if 
not all of the accessible route requirements in ADAAG. The advisory 
committee therefore considered that changing ADAAG to require an 
accessible route serving individual work stations would not have 
dramatic impact. This aspect of the model building codes, as well as 
general exceptions for equipment and other spaces in section 203, would 
serve to limit the overall impact of this change in the advisory 
committee's view. Further, the requirement for an ``accessible route'' 
to such elements, as opposed to access for ``approach, entry, and 
exit'' to certain spaces was considered clearer and more easily 
interpreted.
    The Board is committed to harmonizing the ADAAG requirements with 
the requirements of the model codes and believes that covered entities 
should apply the recommendations of the advisory committee in most 
situations, particularly in traditional places of public accommodation, 
in office buildings, and in schools. However, the Board is concerned 
that the adoption of this requirement as the minimum level of 
compliance may prove to be unworkable in some employment settings. 
Therefore, the Board has not included the advisory committee's 
recommendations in this proposed rule. However, the Board is 
considering whether to include the advisory committee's language in the 
final rule. To facilitate this decision, the Board is seeking responses 
to the following questions:
    Question 1: ADAAG requires that an accessible route be provided to 
employee work areas, but not to individual work stations. What 
obstacles have people with disabilities encountered as a result of this 
provision?
    Question 2: The Board is interested in learning what the impact 
might be if ADAAG requires access to ``individual work stations'' 
rather than to ``employee work areas.'' For example, how would a 
facility otherwise be designed and built in the absence of this revised 
requirement in ADAAG? Any comparative analysis should be based on a 
design that reflects compliance with contemporary codes, such as the 
model building codes, and typical design practice. In other words, 
aspects of an accessible route that would otherwise be provided as a 
typical design consideration or that would have to be provided in order 
to comply with a contemporary building code would not be sources of 
real impact.
    Question 3: Are there specific types of individual work stations, 
not otherwise exempt from access by section 203, that could not be 
served by an accessible route?
    Question 4: The phrase ``areas used only by employees as work 
areas'' has been misinterpreted or considered unclear. If this 
requirement is retained in the final rule, how should it be clarified 
to prevent misinterpretation? If a requirement for work stations is 
included in the final rule, is the term ``individual employee work 
stations'' sufficiently specific or is further clarification, 
qualification, or definition needed?
    The revised guidelines differ from ADAAG in that they require 
employee work areas to be equipped with visual alarms where audible 
alarms are provided. In effect, this will require visual alarm 
appliances in most work areas. Where work areas are enclosed by opaque 
doors and walls, visual alarm appliances will be necessary to provide 
the required alarm coverage. However, where work areas have translucent 
walls or doors, carefully placed alarm appliances in adjoining 
corridors or other spaces can cover the work area. This is a change 
from current ADAAG, which requires visual alarms in common use and 
public use spaces, but not in those spaces that serve only as a work 
area. The Board proposes this change because it is an issue of life 
safety and because installation of visual alarms after construction can 
be difficult and expensive. However, in addition to an accessible 
connecting route, visual alarms would be the only accessible element 
required for a work area.
    The Board estimates that the aggregate cost associated with 
providing visual alarms in employee work areas for newly constructed 
buildings is approximately $16.3 million. This estimate is based on 
several assumptions: (a) an average office building size is 200,000 
square feet with 200 square feet per office; (b) the cost of an alarm 
system complying with existing requirements is $225,000 and 
approximately 60 to 70 percent of the area of the office building 
receives visual alarm coverage; (c) visual alarms will be needed in an 
additional 25 percent of the building area (50,000 square feet, 250 
offices) to meet the proposed new requirement; (d) the additional cost 
for installing the visual alarms in employee work areas is $65,375 
($261 per office); (d) 250 office buildings (averaging 200,000 square 
feet) are newly constructed each year.
    Question 5: This provision would be applicable to both newly 
constructed buildings and existing buildings when alarm systems are 
replaced or upgraded, and these alterations affect the usability of the 
building. The Board does not provide an aggregate cost estimate for 
existing buildings when alarm systems are altered. The Board recognizes 
that this cost may greatly exceed the cost for newly constructed 
buildings. In order to better assess the overall cost of this 
provision, the Board seeks data on how frequently alarm systems are 
replaced or upgraded such that they would amount to an alteration and 
be subject to this provision. The Board has been advised that alarm 
systems may be replaced as often as every ten years. The reason given 
is that building owners desire to reduce insurance liability, as well 
as to provide state-of-the-art protection for building occupants. Is it 
correct to assume that alarm systems are replaced every ten years? The 
Board seeks information from businesses that provide fire alarm systems 
regarding the additional cost of providing visual alarms in employee 
work areas when alarm systems are replaced or upgraded. Please provide 
cost data for alarm systems with visual alarm coverage in all employee 
work areas compared to alarm systems complying with the existing 
requirements. Lastly, while an average building size is used in 
developing the cost estimate for newly constructed buildings, the Board 
seeks comment on whether the provision would have a disproportionate 
economic impact on small buildings or businesses.
    Question 6: Are there less costly alternatives to providing visual 
alarms in all employee work areas for employees who are deaf or are 
hard of hearing that provide a comparable level of life safety?
    Question 7: Concerns have been raised about limiting the number of

[[Page 62253]]

visual alarms for the benefit of people who are photosensitive, as 
further discussed below at section 702.3. In view of these various 
considerations, comment is sought on the appropriateness of this 
requirement, and information is requested on whether there are means 
available for deactivating individual visual appliances (which may be 
desired in accommodating employees who are photosensitive) without 
rendering the entire system ineffective.
    Section 203.9 clarifies that in residential facilities access is 
not required in common use areas not serving required accessible 
dwelling units. The Board added this provision because guidelines for 
residential facilities have been included in this rule. This provision 
would apply in situations where certain common use areas, such as 
laundry rooms, are intended to serve a portion of dwelling units.

204  Protruding Objects

205  Operable Parts

    Sections 204 and 205 are substantively consistent with scoping 
requirements for protruding objects in ADAAG 4.1.2(3) and 4.1.3(2) and 
for controls and operating mechanisms in ADAAG 4.1.3(13).

206  Accessible Routes

    ADAAG addresses scoping for accessible routes in several areas 
(4.1.2, 4.1.3, and 4.3). The revised guidelines bring these 
requirements together into one subsection (206.2) to clarify the 
requirement for accessible routes from site arrival points, within the 
site and within buildings and facilities, and to spaces and elements. 
The revised guidelines more clearly recognize various elements as 
components of accessible routes. Thus, this section integrates scoping 
for entrances (206.4), doors and doorways (206.5), elevators (206.6), 
and wheelchair (platform) lifts (206.7). Changes from ADAAG include:
    <bullet> clarification that an accessible pedestrian route is not 
required where only a vehicular way not serving pedestrians is provided 
(206.2.1 and 206.2.2, exceptions);
    <bullet> emphasis on the provision of an ``accessible route'' 
between floors as opposed to an ``elevator'' so that elevator 
exceptions in ADAAG 4.1.3(5) are relocated to the requirement for an 
accessible route (206.2.3);
    <bullet> clarification that in assembly areas an accessible route 
is not required to serve seating that does not contain wheelchair 
spaces or designated aisle seats required to be on an accessible route 
(206.2.3, exception 6);
    <bullet> clarification that an accessible route between seating and 
performance areas is required where a direct connection is provided 
(206.2.6);
    <bullet> clarification that where the circulation path is interior, 
the accessible route must be interior as well (206.3);
    <bullet> removal of the requirement in ADAAG 4.1.3(8) that 
accessible entrances be provided in a number at least equal to the 
number of exits required because entrances and exits serve different 
functions and should not be linked in scoping requirements;
    <bullet> removal of a requirement in ADAAG 5.7 for an accessible 
route to raised platforms in banquet rooms since it is premised on 
elements (head tables and speaker's lecterns) that often are not fixed;
    <bullet> extending the scope of requirements for security check 
points and security barriers for airports and certain State and local 
government facilities to cover all types of facilities that provide 
security check points and barriers (206.8); and
    <bullet> removal of ADAAG exception 4(d) to 4.1.3(5) that allows 
the use of wheelchair lifts where ``existing site constraints or other 
constraints make use of a ramp or an elevator infeasible'' since this 
is not considered warranted in new construction.
    In addition, several substantive changes are provided that pertain 
to elevators (206.6). These include recognition of two alternatives to 
the traditional type of elevator required by ADAAG and the addition of 
a requirement for altered elevators.
    Destination-oriented elevators are different from typical elevators 
in that they provide a means of indicating the desired floor at the 
location of the call button, usually through a key pad, instead of a 
control panel inside the car. Responding cars are programmed for 
maximum efficiency by reducing the number of stops any passenger 
experiences. ADAAG does not specifically address this type of elevator, 
which was not widely in use when ADAAG was first published. The revised 
guidelines require compliance with newly added technical requirements 
in 407.3 where destination-oriented elevators are provided instead of 
traditional types of elevators. There are differences in the technical 
requirements provided in section 407. For example, standard elevators 
must provide audible and visual car position indicators that identify 
floors as they are passed. With destination-oriented elevators, audible 
and visual indicators must be provided indicating the car destination 
both when the car arrives in response to the call and when it arrives 
at the floor destination.
    The revised guidelines also permit installation of limited-use/
limited-application (LULA) elevators in buildings and facilities not 
required to have a standard elevator. This type of elevator is 
characterized by a smaller car among other things. The revised 
guidelines provide technical requirements in 407.4 and require 
compliance with the industry safety standard (ASME/ANSI A17.1, Part 
XXV). The advisory committee recommended addressing LULAs because it 
considered such elevators a more viable option in situations where a 
standard elevator is not required. The advisory committee reasoned that 
some vertical access (via a LULA elevator) is preferable to none.
    Question 8: Consistent with ADAAG, the revised guidelines provide 
an exception for private sector facilities based on the number of 
stories or the square footage per floor (206.2.3, exception 1). A much 
narrower exception is permitted for State and local government 
facilities (206.2.3, exception 2). Are there situations where the use 
of LULA's should be permitted instead of a standard elevator in certain 
small State or local government facilities?
    A requirement has been added at 206.6.1 that when an elevator is 
altered, all elevators programmed to respond to the same hall call 
control shall be brought into compliance so that persons with 
disabilities are not limited to the use of one car at multi-car 
elevator banks.

207  Accessible Means of Egress

    Requirements for accessible means of egress have been modified for 
consistency with model building codes and standards, including addition 
of a new requirement that an elevator be provided as an accessible 
means of egress in buildings with four or more stories above or below 
the exit discharge level. The requirement in ADAAG 4.1.3(9) that 
accessible means of egress be provided in the ``same number'' of 
required exits has been changed to require at least two accessible 
means of egress where more than one means of egress is required. The 
requirement in ADAAG 4.1.3(10) that accessible routes also serve as 
required exits has been removed because not all accessible routes 
necessarily have to serve as a required means of egress in order to 
provide a reasonable minimum level of safety. The reference to ``areas 
of rescue assistance'' has been changed to ``areas of refuge'' for 
consistency with model

[[Page 62254]]

codes. Exceptions from the requirement for areas of refuge in 
facilities that are altered or those equipped with supervised automatic 
sprinkler system have been retained. A new exception clarifies that 
areas of refuge are not required in open parking garages since the open 
design permits smoke to escape.

208  Parking Spaces

    The revised guidelines maintain the general scoping of ADAAG in 
4.1.2(5) but refer to parking spaces generally, instead of to ``self-
parking by visitors, employees, or both.'' The Board has added an 
exception in 208.1 for parking spaces used exclusively for buses, 
trucks, delivery vehicles, law enforcement vehicles, and vehicular 
impound and motor pool lots where lots accessed by the public are 
provided with an accessible passenger loading zone.
    ADAAG 4.1.2(5)(d) requires a higher level of scoping for outpatient 
units and facilities (10%) and those that ``specialize in treatment or 
services for persons with mobility impairments'' (20%). Sections 
208.2.1 and 208.2.2 preserve these scoping requirements but clarify 
their application to visitor and patient parking (so as to exclude 
employee parking); ``hospital outpatient facilities'' (10%); and 
``rehabilitation facilities and outpatient physical therapy 
facilities'' (20%). The advisory committee had recommended removing the 
10% requirement for outpatient facilities because it questioned the 
technical basis for it and because the term ``outpatient facility'' is 
too broad and can be misapplied to doctors' offices and clinics. 
Instead of removing this requirement, the Board has clarified its 
application by limiting it to outpatient facilities located in 
hospitals. The requirement for ``rehabilitation facilities'' is 
intended to cover facilities providing physical rehabilitation, but not 
those facilities providing other types of rehabilitation, such as drug 
or alcohol rehabilitation.
    New scoping provisions for residential facilities have been added. 
Section 208.2.3 provides access to at least one parking space for each 
accessible dwelling unit where parking is provided. Two percent of any 
additional parking spaces provided for residents must be accessible. 
Additionally, guest parking must be made accessible in accordance with 
Table 208.2. In 208.4.2 dispersion is required throughout all types of 
parking provided for dwelling units required to be accessible unless 
equal or greater accessibility is otherwise achieved.
    Requirements for identification of accessible spaces in 208.3 allow 
spaces not to be identified (i.e., reserved solely for use by people 
with disabilities) where five or fewer spaces in one parking lot are 
provided. This was recommended by the advisory committee in order to 
mitigate the impact of a reserved space in very small lots and is based 
on the model building codes. Identification of spaces is not required 
at residential facilities where parking spaces are assigned to specific 
dwelling units. The requirement for the ``van accessible'' designation 
has been removed to clarify that both car and van drivers can use such 
spaces, as was the original intent of ADAAG.
    ADAAG 4.1.2(5)(e) allows an accessible passenger loading zone 
instead of accessible parking spaces at facilities with valet parking. 
This provision has been removed for several reasons. Valet parking 
often is not available at all hours a facility is open or may be later 
removed altogether. Further, vehicles specially equipped for persons 
with disabilities may not be usable by other drivers.

209  Passenger Loading Zones

    This section requires that where a passenger loading zone is 
provided, at least one portion within every continuous 100 feet of 
loading zone space must be accessible. This replaces the requirement in 
ADAAG 4.1.5(c) for only one accessible passenger loading zone per site. 
The new requirement is responsive to facilities, such as airports, 
where many or long continuous passenger loading zones are provided. The 
advisory committee recommended that all passenger loading zones be 
required to be accessible. However, the proposed requirement addresses 
situations where continuous loading zones are provided and balances the 
needs of people with disabilities and the costs associated with adding 
an additional lane for accessible passenger loading.

210  Stairways

    This provision requires all stairs that are part of a means of 
egress to comply with the guidelines. ADAAG 4.1.3(4) requires 
compliance only at stairs connecting levels not connected by a vertical 
means of access. The advisory committee recommended this change for 
consistency with model building codes that recognize the importance of 
accessible safety features in successfully exiting by stairs. 
Accessible features in stairways will benefit individuals with mobility 
impairments, as well as other individuals with and without 
disabilities. An exception is provided for alterations. Under this 
exception, stairs between levels that are connected by an accessible 
route are not required to comply (except for handrails) due to the 
potential difficulty of altering stairs for compliance within existing 
space limitations.

211  Drinking Fountains and Water Coolers

    This provision requires that where one drinking fountain or water 
cooler is provided on a site, floor, or within a secured area, access 
shall be provided for both people who use wheelchairs and for standing 
persons. Where more than one drinking fountain is provided, 50% are 
required to be wheelchair accessible and 50% are required to be 
accessible to standing persons (with rounding up or down permitted 
where an odd number of units is provided). While substantively 
consistent with ADAAG 4.1.3(10), this section clarifies the application 
to exterior units and the coverage of units accessible to standing 
persons where more than one unit is provided. The advisory committee 
recommended that the guidelines not address access for standing persons 
because no technical criteria are provided and because it believed that 
most drinking fountains would accommodate people who have difficulty 
bending. The Board believes that access for people who may have 
difficulty bending or stooping should be retained and has included 
technical requirements for such access (see 602.7).

212  Sinks, Kitchens, Kitchenettes, and Wet Bars

    A requirement has been added that where sinks are provided in 
accessible spaces, at least 5% (but not less than one) must be 
accessible, except for mop or service sinks, which are exempt. While 
ADAAG provides technical requirements for sinks in 4.24, it does not 
indicate the minimum number required to be accessible. New scoping 
provisions for kitchens, kitchenettes, and wet bars are generally 
consistent with transient lodging requirements in ADAAG 9.2.2(7). The 
revised guidelines extend the application to kitchens, kitchenettes, 
and wet bars provided, without regard to the type of facility.

213  Toilet and Bathing Facilities

    This section is consistent with ADAAG scoping provisions in 
4.1.3(11), 4.22, and 4.23 except for one substantive change. Where 
multiple single-user toilet rooms are clustered at a single location 
and contain fixtures in excess of the minimum required number of 
plumbing fixtures, at least 5% of toilet rooms (but not less than one) 
for

[[Page 62255]]

each use at each cluster is required to be accessible (213.2, exception 
4). ADAAG, which does not specifically address this situation, requires 
access to all such toilet rooms. The advisory committee recommended 
this scoping provision as more appropriate since this arrangement is 
common in facilities such as medical facilities. Additionally, 
revisions have been made to clarify that:
    <bullet> access is not required for toilet or bathing facilities in 
transient lodging guest rooms (except for the clearance of entry 
doors), patient or resident sleeping rooms in medical care facilities, 
holding or housing cells in detention and correctional facilities, or 
dwelling units that are not required to be accessible (213.2, 
exceptions 5, 6, 7, and 8);
    <bullet> unisex bathing rooms must contain at least one accessible 
shower or bathtub (213.2.1); and
    <bullet> where only one lavatory is provided, it shall not be 
located in an accessible toilet compartment (213.3.4).

214  Laundry Equipment

    A new scoping provision has been added for laundry equipment and 
applies to laundry facilities wherever provided. For example, if a 
transient lodging facility provides laundry facilities for guests, they 
must be accessible and contain one or more accessible washers and 
dryers. This section also addresses the need for accessible laundry 
facilities in, or serving, accessible dwelling units and is necessary 
since the revised guidelines address residential facilities. Where 
washing machines or clothes dryers are provided in spaces required to 
be accessible, at least one of each type is required to be accessible.

215  Emergency Alarm Systems

    The requirement for emergency alarm systems is consistent with 
ADAAG 4.1.3(14). The ADAAG exception that allows such systems to be 
modified in medical care facilities to suit health care alarm practice 
has been revised as an exception to the charging statement for the 
technical section on fire alarm systems (702.1). The advisory committee 
had recommended that the provision be limited to fire alarm systems for 
consistency with model codes such as National Fire Protection Agency 
(NFPA) 72-G. The committee also recommended that an exception for 
alterations be provided that would require compliance with the 
requirement for visual alarms only where an alarm system is upgraded or 
replaced or a new one installed. Instead, the Board is proposing to 
retain the substance of the current requirement since compliance with 
any requirement in alterations is required to the extent it is 
``technically feasible.'' Given the scope of the work, replacement of a 
fire alarm system is considered an alteration, not normal maintenance. 
However, certain upgrades are alterations only if they affect the 
usability of a room or space. The usability of the space is not 
affected when a few failing appliances are replaced. The Board has 
limited the requirement for visual appliances to fire alarm systems 
instead of ``emergency warning systems.'' In addition, the Board has 
added a scoping provision that requires other types of alarm systems to 
be equipped with audible and visual signals but has not provided any 
technical criteria for these signals.
    Question 9: The Board seeks information on facility alarm systems 
(other than fire alarm systems) that do not instruct occupants to 
evacuate the facility but provide other warning information, such as 
those used for tornado warnings and other emergencies. Recommendations 
are requested on the technical criteria appropriate for the audible and 
visual signals for such alarm systems, particularly where 
differentiation from fire alarm system signals is important.

216  Signs

    This provision retains the substance of scoping for exterior and 
interior signs in ADAAG 4.1.2(7) and 4.1.3(16). Several editorial 
changes are included for clarification. Scoping for tactile signs is 
modified to apply to ``permanent'' room or space designations in order 
to clarify coverage of signs that are not likely to change. The Board 
has added an exception stating that signs designating building 
addresses or building names are not required to meet requirements for 
tactile signs. These revisions are consistent with the Board's 
interpretation of ADAAG.
    ADAAG 4.1.7(3)(e) includes a provision for qualified historic 
facilities which recommends that exhibits and signs displayed 
horizontally should be no higher than 44 inches above the floor so as 
to be accessible to be people seated in wheelchairs. The advisory 
committee recommended that this provision be made mandatory or 
relocated to an advisory note. The Board believes this specification 
and its limited application to qualified historic facilities merits 
further evaluation before adopting it as a mandatory requirement. 
Consequently, this provision is not included in the revised guidelines.

217  Telephones

    Scoping provisions for public pay telephones providing wheelchair 
access and volume controls are substantively consistent with ADAAG 
4.1.3(17)(a) and (b). The Board has provided clarification in 217.1 
that scoping applies to one of each type of pay phone provided, 
including, but not limited to, coin-operated and coinless public pay 
phones. For example, access is not limited to credit card phones where 
coin-operated phones are also provided or vice versa. As recommended by 
the advisory committee, an exception at 217.3 indicates that, where all 
phones are equipped with volume controls, identifying signage is not 
required.
    Significant changes are proposed for the provision of TTYs. TTYs 
are devices that provide access to telephones for people who have 
hearing or speech impairments. At the advisory committee's 
recommendation, the preferred term ``TTY'' has been used instead of the 
term ``text telephone'' or ``TDD'; the definition of TTY in section 106 
explains that the term is synonymous with ``text telephones'' and 
encompasses devices known as ``TDDs,'' a term which stands for 
``telecommunication display devices'' (or ``telecommunication devices 
for deaf persons''). ADAAG 4.1.3(17)(c) generally requires that at 
least one TTY be provided on a site where four or more public pay 
telephones are provided (and at least one is interior). The advisory 
committee and the Board consider this requirement inadequate because it 
does not take into account large sites such as college campuses and 
shopping malls where people who need TTYs are limited to one TTY-
equipped phone. The revised scoping at 217.4 states that in private 
buildings (i.e., places of public accommodation and commercial 
facilities) where four or more pay phones are provided at a bank, 
within a floor, building, or on a site, a TTY is required at each such 
location. Consistent with previous amendments to ADAAG for State and 
local government facilities, a lower threshold is provided for public 
buildings, where one pay telephone on a floor or within a public use 
area of a building triggers the requirement for a TTY. An exception for 
the requirement at banks (271.4.1) makes optional TTYs at banks that 
are within 200 feet of, and on the same floor as, a bank with a TTY. 
This exception allows reasonable dispersion without triggering a 
requirement for additional TTYs. The revised provision does not limit 
scoping to where at least one pay telephone is interior since TTYs for 
exterior application are readily available.
    A new scoping provision is provided for rest stops, emergency 
roadside stops, and service plazas that requires a TTY

[[Page 62256]]

where at least one public pay telephone is provided since 
telecommunications can be critical at such locations and searching for 
off-highway TTYs would be impractical. Due to the increased scoping, a 
TTY requirement specific to stadiums, arenas, conventions centers, etc. 
in ADAAG 4.1.3(17)(c)(ii) has been removed. Scoping requirements for 
hospitals and the secured areas of detention and correctional 
facilities have been retained.
    In addition to the advisory committee's recommendations, Board 
changes include:
    <bullet> adding a requirement for TTY signage where directional 
signs for public pay telephones is provided (271.4.9.2); and
    <bullet> exempting phone banks with TTYs from the requirement for 
shelves and outlets for portable TTYs (217.5).

218  Transportation Facilities

    This provision requires transportation facilities to comply with 
Chapter 10. Transportation is the one occupancy type (in addition to 
the chapter the Board has added on residential facilities) that the 
advisory committee recommended remain a separate chapter. Scoping for 
other occupancy types covered in ADAAG sections 5 though 12 have been 
integrated into Chapter 2.

219  Assistive Listening Systems

    This section covers requirements for assistive listening systems 
and receivers in assembly areas. Section 219.2 requires an assistive 
listening system in each assembly area where audible communication is 
integral to the space and audio amplification is provided. However, in 
courtrooms, this requirement also applies where audio amplification is 
not provided, consistent with ADAAG as amended for judicial facilities. 
This provision is substantively different from ADAAG 4.1.3(19) in three 
respects. First, ADAAG requires assistive listening systems in assembly 
areas without audio amplification if the seating capacity is 50 or 
more, and the revised guidelines do not, except in courtrooms 
(regardless of seating capacity). Second, ADAAG's requirement is 
conditioned on the provision of fixed seats; the revised guidelines 
would apply to assembly areas with fixed seating and those without. 
Third, ADAAG requires that assembly areas not subject to the 
requirement for a ``permanent'' system be equipped with the necessary 
electrical outlets and wiring for a portable system; the revised 
guidelines do not specify a ``permanent'' system and do not require 
outlets and wiring for portable systems. These also represent changes 
from the advisory committee's report, which recommended a scoping 
provision generally consistent with ADAAG. The Board is proposing these 
changes because it believes that any assembly area with audio 
amplification should be equipped with an assistive listening system 
whether or not seating is fixed. The Board removed the requirement in 
ADAAG for outlets and wiring because adequate electrical support is 
generally available in these assembly occupancies and because the 
provision of a portable system is more appropriately covered by the DOJ 
regulation, which contains requirements for the provision of auxiliary 
aids and services necessary to ensure effective communication.

---------------------------------------------------------------------------

    Section 219.3 specifies the minimum number of receivers according 
to a sliding scale. This is a change from the flat 4% requirement in 
ADAAG 4.1.3(19) and was recommended by the advisory committee based on 
actual and anecdotal evidence that the current requirement exceeds the 
demand especially in large facilities. Scoping of 4% is maintained for 
a seating capacity up to 500 seats; seating above this number is 
reduced to 3.5% (501 to 1000 seats), 2.75% (1001 to 2000 seats), and 1% 
(over 2000 seats). The revised guidelines include a requirement which 
is not in ADAAG that a portion of receivers (25% but no less than 2) be 
compatible with hearing aids. In effect, this requires provision of 
neck loops, which are the only type of receiver that can be used 
comfortably with all models of hearing aids equipped with a telecoil.

220  Automatic Teller Machines and Fare Machines

    This provision is consistent with ADAAG 4.1.3(20) with respect to 
automatic teller machines, but it also addresses ``fare vending, 
collection, or adjustment machines,'' which are only addressed by ADAAG 
where provided in transportation facilities.

221  Assembly Seating

    This section is substantively different from ADAAG requirements and 
advisory committee recommendations for wheelchair, companion, and 
designated aisle seating. Section 221.1 lists the types of assembly 
areas covered: ``a motion picture house, theater, concert hall, 
stadium, arena, auditorium, convention center, lecture hall, courtroom, 
legislative chamber, or similar assembly area.'' This approach of 
defining the section's coverage by providing a list of exemplary 
covered entities is a departure from that in the existing ADAAG 
4.1.3(19), which describes covered entities as ``places of assembly 
with fixed seating.'' By limiting coverage to the listed entities and 
``other similar assembly areas,'' the revised guidelines clarify that 
assembly areas like libraries or restaurants are not required to comply 
with the requirements of 221.
    Section 221.2 revises the number of wheelchair spaces required 
(Table 221.2.1). For a seating capacity up to 50 spaces, the 
requirement is the same as ADAAG 4.1.3(19). For a seating capacity of 
51 to 150 seats, 4 wheelchair spaces are required, and for a seating 
capacity of 151 to 300 spaces, 5 wheelchair spaces are required. The 
remainder of the table coincides with ADAAG. The advisory committee 
recommended the scoping increase (although it recommended that 5 
wheelchair spaces be provided starting at 101 seats instead of 151). 
Also, the advisory committee recommended that scoping for a seating 
capacity over 500 be reduced from 1% to 0.5% based on anecdotal 
information on usage. The Board is not persuaded by this anecdotal 
information and is proposing to retain the ADAAG requirement of 1%. 
Section 221.2 also states that wheelchair spaces shall be provided in 
each luxury box, club box, and suite. This is consistent with 
Department of Justice interpretations of ADAAG that treat each such box 
or suite as a discrete assembly area. Wheelchair spaces must be 
integrated into the general bowl design and seating plan and cannot be 
set aside on a separate platform or level where there is little or no 
other seating. Integration of wheelchair spaces will provide 
opportunities for social interaction with persons sitting in the 
closest seats.
    The advisory committee recommended that wheelchair spaces be 
clustered and specified the number of wheelchair clusters permitted, 
which, in effect, served to govern the minimum level of dispersion. The 
advisory committee also recommended a reduced level of dispersion where 
sight lines require more than one step for a rise in elevation between 
rows and in alterations where dispersion is not technically feasible. 
The Board has not adopted this recommendation. The Board has included 
requirements for dispersion as a technical requirement (see 802).
    Section 221.3 contains a requirement included by the Board that a 
companion seat be provided for each wheelchair space and that this seat 
be readily removable to create an additional wheelchair space. This is 
consistent with current interpretations of the

[[Page 62257]]

requirement for one companion seat to be provided next to each 
wheelchair seating area. However, ADAAG 4.33.3 requires companion seats 
to be fixed but does allow readily removable seats to be installed in 
wheelchair spaces. The revised provision will afford greater 
flexibility in seating arrangements by allowing the choice of either a 
companion seat or another wheelchair space next to each required 
wheelchair space. The Board considered other options for addressing 
problems presented by fixed companion seating. Those options included: 
requiring a lesser number of fixed companion seats than wheelchair 
spaces in larger assembly areas; requiring that a specified number of 
wheelchair spaces be designated to accommodate a group of three or more 
persons using wheelchairs; or opting for no change from the requirement 
in the current ADAAG. The requirement for readily removable companion 
seating was chosen for simplicity, because it promotes greater 
flexibility in the seating configurations. However, the Board has 
included an exception providing that fixed companion seating is 
permitted in assembly areas with a capacity of 300 or fewer seats. This 
exception is provided because the requirement for removable companion 
seats would have a disproportionate impact on smaller assembly 
facilities where no more than five wheelchair and companion spaces are 
required.
    Question 10: The Board seeks information on the impact of the 
requirement that each wheelchair space have an adjacent companion seat 
that can be removed to provide an adjoining wheelchair space. Of 
particular interest are recommendations on design solutions or 
alternative scoping requirements that will mitigate the space impact 
while affording a similar level of flexibility in seating arrangements.
    Question 11: The Board believes that readily removable seats should 
provide a companion with virtually the same experience in terms of 
comfort and usability as fixed seats in the same assembly facility. 
What specific characteristics should the readily removable seat have 
when compared to other seats? While a metal folding chair is not 
equivalent to a plush theater-style seat, is it sufficiently comparable 
to a bleacher seat?
    Section 221.4 requires that 1% of seats be designated aisle seats. 
At least 25% of the designated aisles seats must be on an accessible 
route, and the remainder no more than two rows from an accessible 
route. ADAAG 4.1.3(19) provides a similar requirement that 1% of seats 
be aisle seats with removable, folding, or no armrests. This 
requirement is intended to serve people who may have difficulty walking 
between rows of seats, use assistive devices for ambulation, or wish to 
transfer from wheeled mobility aids. The advisory committee did not 
recommend retaining this requirement because, with respect to 
wheelchair transfers, questions arise about the proximate storage of 
mobility aids and the potential obstruction of aisles by mobility aids. 
Further, the advisory committee noted that ADAAG did not require an 
accessible route to such seats, which brought into question the 
usefulness of this requirement for people wishing to transfer from 
wheelchairs to seats. The Board has included a requirement for a 
portion of aisle seats to be on accessible routes for people using 
wheelchairs who wish to transfer to seats. Since aisle seats also 
benefit people who have difficulty walking, including between rows of 
seats, but who can use stairs, the remainder of seats can be separated 
from the accessible route by no more than two rows.
    Question 12: At least 1% of seats must be designated aisle seats 
that have folding or removable armrests or no armrests. The Board seeks 
information on the cost and related design impacts of locating at least 
25% of these designated aisle seats on an accessible route and of 
locating the remainder of such seats no more than two rows from an 
accessible route.
    Section 221.5 provides a new requirement that where elevators or 
wheelchair lifts are provided on an accessible route to wheelchair 
spaces or designated aisle seats, they shall be provided in ``such 
number, capacity, and speed'' in order to provide a level of service 
equivalent to that provided in the same seating area to patrons who can 
use stairs or other means of vertical access. The Board added this 
requirement to ensure an equal level of convenience between accessible 
seating and inaccessible seating. Architects plan for efficient ingress 
and egress when they design assembly facilities, particularly stadiums. 
Designers should have available circulation data that is part of the 
architectural program and design. Generally, designers of new 
facilities have sufficient knowledge of the travel time between points 
(e.g., between the entry gate and seats or between the seats and 
concession stands) to comply with this requirement for equivalent 
vertical access.

222  Dressing, Fitting, and Locker Rooms

    This provision is generally consistent with ADAAG 4.1.3(21), but it 
also specifically references locker rooms in order to clarify the 
intended application. An exception permitting unisex facilities for 
altered dressing, fitting, or locker rooms derives from a similar 
provision in ADAAG 4.1.6 (3)(h).

223  Medical Care Facility Patient or Resident Sleeping Rooms

    This provision is substantively the same as ADAAG 6.1 in providing 
scoping for patient or resident sleeping rooms. The revised guidelines 
clarify coverage of ``licensed medical and long-term care facilities.'' 
The description of the facilities covered has been simplified by 
removing the ADAAG reference to medical facilities ``where persons may 
need assistance in responding to an emergency,'' as the advisory 
committee considered this portion of the description not useful. 
Scoping for alterations and additions in ADAAG 6.1(4) has been 
simplified in stating that the minimum percentage is to be based on the 
total number of sleeping rooms added or altered.
    While section 223 specifies the minimum number of sleeping rooms 
required to be accessible in medical care facilities, it does not 
specify dispersion among different types of sleeping rooms. The Board 
believes that accessible bedrooms should be dispersed among all units 
or departments providing overnight stay and among different classes of 
rooms, such as private, semi-private, etc. Industry practice and needs 
assessment can be used to further determine the distribution. For 
example, a greater number of accessible sleeping rooms might be located 
in general surgical units than in pediatric or obstetric wards. 
However, the use and designation of units or types of rooms often 
change over time as needed.
    Question 13: The Board seeks comment on how dispersion of 
accessible sleeping rooms can be effectively achieved and maintained in 
medical care facilities such as hospitals and long term care 
facilities. A requirement for such dispersion may be included in the 
final rule.

224  Transient Lodging Guest Rooms

    The minimum number of accessible guest rooms required has not been 
changed from that provided in ADAAG 9.1.2. However, Table 224.2 
clarifies that guest rooms with roll-in showers are to be provided in 
addition to the basic number of required accessible

[[Page 62258]]

guest rooms. In addition, there are two substantive changes that are 
also based on the advisory committee's recommendations. First, section 
224.3 is new and addresses the number of beds required to be accessible 
for situations such as homeless shelters, where a room may have a large 
number of beds. Scoping is provided in Table 224.3.
    Second, the Board has significantly revised the scoping provisions 
in section 224.4 for the number of guest rooms equipped with accessible 
communication features, including visual alarms and devices that 
provide visual notification of incoming telephone calls and door knocks 
or bells. ADAAG 9.1.3 provides a minimum number according to a sliding 
scale based on the total number of rooms provided. It requires 1 in 25 
rooms to comply up to a guestroom count of 100. Scoping successively 
decreases to 1 for every 50 rooms for the next 101 to 200 rooms and to 
1 for every 100 rooms for the next 201 to 500 rooms. For facilities 
with 501 to 1000 rooms, 2% of rooms must comply and where the room 
count exceeds 1000, the scoping drops to 1%. ADAAG 9.2.2(8) requires 
that all wheelchair accessible rooms be equipped with accessible 
communication features in addition to a number of rooms required to 
provide communication access only. The Board is proposing to increase 
the minimum number of rooms that provide accessible communication 
features to 50% of the total number of guest rooms provided. This 
increase is proposed for several reasons. The communication features 
addressed in this requirement address life safety in providing visual 
notification of fire alarms for people who are deaf or hard of hearing. 
Higher scoping will also afford greater flexibility in the guest room 
assignment of people who are deaf or hard of hearing, particularly in 
light of revisions to technical requirements for visual alarms in 
section 702.3 that effectively preclude the use of portable visual 
alarm devices. Further, anecdotal evidence indicates that operational 
alternatives used in accommodating individuals who are deaf or hard of 
hearing, including the use of portable devices and facility staff to 
directly alert guests of the need to evacuate the facility, are 
unreliable and ineffective.
    Question 14: Permanent installation of visual alarm appliances is 
considerably cheaper and easier to achieve as part of facility design 
and construction than as a retrofit. The Board requests information on 
the new construction cost difference between providing visual alarms 
and notification devices for incoming telephone calls and door knocks 
or bells according to the scoping in ADAAG 9.1.3 and the proposed 50% 
scoping requirement. Information is also sought on whether exceptions 
should be provided for altered facilities or additions.
    Question 15: It is the Board's understanding that some transient 
lodging facilities, particularly hotel chains, have adopted voluntary 
policies requiring permanently installed visual alarms in all or a 
majority of newly constructed guest rooms. Please provide information 
regarding those transient lodging facilities that have such a policy. 
Are there less costly alternatives to providing visual alarms in fifty 
percent of guest rooms that will provide guests who are deaf or are 
hard of hearing a comparable level of life safety?
    Section 224.5 requires dispersion of accessible rooms among the 
various classes of rooms provided, including room type, bed type, and 
other amenities to a degree comparable to the choices provided other 
guests. This is similar to a requirement in ADAAG 9.1.4(1). A 
clarification has been added that when complete dispersion is not 
possible due to the number of rooms required to be accessible, 
dispersion is to be provided in the following order of priority: room 
type, bed type, and amenities. The advisory committee recommended that 
the factors for dispersion were more appropriate for advisory 
information. The Board has retained this provision in the text of the 
rule since it contains mandatory direction. Consistent with the 
advisory committee's recommendation, section 224.5 also requires 
communication access in 50% of the wheelchair accessible guestrooms in 
addition to the requirement in section 224.4. This differs from ADAAG 
9.2.2(8) which requires that all wheelchair accessible guestrooms be 
equipped with accessible communication features.

225  Self-Service Storage Facilities

    This is a new requirement recommended by the advisory committee. 
ADAAG does not specifically address self-service storage facilities, 
and many ADAAG users questioned how access should be provided. Scoping 
as provided in Table 225.1 is 5% but drops to 2% after the first 200 
spaces. Accessible storage spaces are required to be dispersed among 
the various classes of units provided to the extent the number of 
accessible spaces allows. Where a facility is comprised of multiple 
buildings, accessible spaces can be clustered in one building. This 
provision addresses concerns raised by the self-storage industry 
regarding the number of entrances required to be accessible in 
facilities that may have more than fifty entrances to separate spaces. 
The advisory committee believed these unique circumstances warranted 
specific attention.

226  Dining and Work Surfaces

    Scoping for dining and work surfaces is consistent with ADAAG 
4.1.3(18). This provision integrates requirements for dispersion and 
dining counters that derive from the section on restaurants and 
cafeterias in ADAAG 5.1 and 5.2, respectively. However, the revised 
guidelines apply the dispersion requirement generally to all dining and 
work surfaces, whereas ADAAG 5.1 requires dispersion only for 
restaurant and cafeteria seating.

227  Sales and Service Counters

    This section corresponds to requirements for business and 
mercantile facilities in ADAAG 7. Section 227.2 provides scoping for 
check-out aisles that is consistent with ADAAG 7.3. This scoping 
however is not limited to business and mercantile occupancies and 
applies to all facilities with check-out aisles. It replaces a 
requirement in ADAAG 8.3 specific to check-out areas in libraries that 
requires at least one lane at check-out areas to comply. There is a 
substantive change to exceptions from the scoping requirement. ADAAG 
7.3 permits only one check-out aisle to be accessible where selling 
space is less than 5000 square feet. It also permits one check-out 
aisle of each design to be accessible in alterations of facilities with 
more than 5000 square feet of selling space. This is required until the 
number of accessible check-out aisles of each design equals the number 
required in new construction. The advisory committee recommended 
retaining these exceptions. However, the Board has removed the 
exception for facilities with less than 5000 square feet of selling 
space because small facilities rarely have more than one check-out 
aisle. In fact, small facilities generally have point of sales and 
service counters in lieu of check-out aisles. The exception for 
alterations has been retained but has been made generally applicable 
and is not limited to facilities with more than 5000 square feet of 
selling space. Requirements for identification of accessible check-out 
aisles in 227.2.1 includes a clarification that, where all check-out 
aisles are accessible, such identification is not required.
    Section 227.3 covers point of sales and service counters. This 
provision is consistent with ADAAG 7.2 except that no distinction is 
made between counters

[[Page 62259]]

with cash registers and those without, which the advisory committee 
considered insignificant.
    Requirements for food service lines in ADAAG 5.5 have been 
integrated into the scoping provision in 227.4. A new provision for 
queues and waiting lines at 227.5 clarifies that an accessible route is 
to be maintained where a defined circulation route is provided. A 
requirement for an accessible route through security bollards in ADAAG 
7.4 has been clarified and relocated to section 206.8. Section 206.8 
clarifies that security may not obstruct ingress or egress.

228  Storage

    Provisions for storage are consistent with those in ADAAG 
4.1.3(12). Examples of the types of storage elements covered have been 
moved to an advisory note. A new provision is provided in 228.2 that 
requires at least 5% of lockers to be accessible. Requirements for 
self-service shelving in section 228.3 are consistent with ADAAG 
4.1.3(12). The Board has removed a reference to display units because 
displays are not to be touched and therefore cannot be self-service. 
The requirement has been made generally applicable to all facilities 
types, not just mercantile occupancies, and effectively replaces 
requirements in ADAAG 8.5 specific to library stacks. A new provision 
is added for coat hooks and folding shelves in 228.4 to clarify, that 
where such elements are provided in toilet rooms or compartments, 
locker rooms, or dressing and fitting rooms, at least one of each type 
shall be accessible.

229  Depositories, Vending Machines, Change Machines, and Mail Boxes

    This provision represents a change from ADAAG 5.8 which addresses 
vending machines and other equipment in restaurants and cafeterias. 
ADAAG provides only for clear floor space at such equipment. Consistent 
with the advisory committee's recommendation, requirements have been 
added for wheelchair turning space and the location of operable 
controls within accessible reach ranges in accordance with section 309 
at vending machines. In addition, the Board has added a requirement 
that operable controls meet the operating characteristics specified. 
The Board also has added specific references to ``depositories, change 
machines, and mail boxes'' and an exception that exempts drive-up only 
depositories from compliance. In view of the coverage of residential 
and other commercial facilities, the Board has included a provision 
that 5% of mail boxes be accessible where provided in an interior 
location. In residential facilities where interior or exterior mail 
boxes are provided on site, access is required to mail boxes serving 
dwelling units that are required to be accessible. The Board does not 
intend that this provision address U.S. Postal Service mail boxes in 
the public right-of-way because these elements may be provided in 
communities without accessible routes.

230  Windows

    The technical provisions for windows are reserved in ADAAG. Where 
glazed openings are provided for operation by the occupants of 
accessible spaces, the revised guidelines include a new provision which 
requires access to at least one glazed opening. In accessible rooms or 
spaces, access is also required to each glazed opening required by the 
administrative authority to be operable. The advisory committee and the 
Board reasoned that if windows are to be operable, they must be 
operable by all potential building occupants, including people with 
disabilities. Furthermore, new technology, including mechanical or 
electrical devices makes providing accessible windows possible.
    Section 230 requires that the operable parts of windows be 
accessible, but it does not address the height of glazed openings. 
Requirements for toilet room mirrors specify that the bottom edge of 
the reflecting surface be no more than 40 inches from the floor 
(section 603.3), and provisions for automatic teller machines require 
display screens to be visible from a point 40 inches above the center 
of the clear floor space in front of the machine (section 707.5.4).
    Question 16: Should a maximum sill height for the glazed area of 
those windows required to be accessible be specified in the final rule 
so that people who use wheelchairs, located on any floor, can look 
through the window to view ground level activities? If so, what should 
this height be? The Board also seeks information on any design 
requirements, practices, or considerations that would specify 
installation above an accessible height in certain occupancies for 
security or safety reasons, such as to guard against break-ins or to 
prevent improper use by building occupants, including children. 
Information is sought on any other design impacts, such as the use of 
the space or cavity below windows for mechanical or other building 
systems.

231  Two-Way Communication Systems

    In amending ADAAG to cover State and local government facilities, 
the Board added a requirement that where a two-way communication system 
is provided to gain admittance to a judicial, legislative, or 
regulatory facility, audible and visual signals must be provided. Also 
included was a requirement that handsets have a cord at least 29 inches 
long. In the revised guidelines, the Board has made this requirement 
applicable to all types of facilities where such two-way communication 
systems are provided.

232  Judicial Facilities

    This provision integrates scoping requirements for judicial 
facilities contained in ADAAG 11 without substantive change. Provisions 
in ADAAG 11 for legislative and regulatory facilities have been 
integrated into other scoping provisions of Chapter 2.

233  Detention and Correctional Facilities

    This section covers scoping for detention and correctional 
facilities, including the minimum number of holding and housing cells 
required to be accessible. These provisions are based on ADAAG 12 and 
have been edited to be consistent with the format of the revised 
guidelines. In addition, several substantive changes have been made. 
ADAAG 12.4.5 reserves scoping for accessible holding or housing cells 
in alterations. In publishing final amendments for State and local 
government facilities, the Board acknowledged that prison operators 
commenting on the proposed amendments urged that access not be required 
in altered correctional facilities because some existing facilities 
would not be able to support inmates with disabilities even if cells 
were made accessible. These comments also pointed to difficulties in 
complying due to design constraints unique to correctional facilities. 
In response, the Board had reserved a proposed scoping requirement for 
altered cells, but noted that public entities, including correctional 
entities, have an obligation to provide program access, as required by 
the Department of Justice (DOJ) title II regulations. Further, the 
Board noted that the program access requirement may effectively 
determine the degree of access necessary in an alteration. In the 
revised guidelines, the reserved provision has been replaced with an 
exception at 233.2 which states that in the alteration of holding or 
housing cells or rooms accessibility is required ``to the extent 
determined by the Attorney General.'' DOJ's title II regulation states 
that public entities must operate each service, program, or activity so 
that the service, program, or activity, when

[[Page 62260]]

viewed in its entirety, is readily accessible to and usable by 
individuals with disabilities. DOJ may revise its title II regulation 
to provide more specific guidance as to the extent to which the 
requirements for accessible cells or rooms in detention and 
correctional facilities apply to alterations. A similar exception also 
is provided for special holding and housing cells or rooms in section 
233.3.
    Exceptions are provided at F223.2 and F233.3 for corresponding 
provisions for detention and correctional facilities covered by the 
ABA. These exceptions, however, refer to applicable agency regulations 
implementing section 504 of the Rehabilitation Act for determining the 
extent to which access is required in the alterations of cells or rooms 
in detention and correctional facilities. The lack of a specific 
requirement for alterations to cells or rooms does not excuse a Federal 
agency or a federally funded entity from providing access to all of a 
prison's programs and services, when viewed in their entirety, if 
required under applicable section 504 regulations.
    In addition, two other changes have been made by the Board:
    <bullet> guidance is provided on the number of beds required to be 
accessible within a room as specified for transient lodging facilities 
in Table 224.3; and
    <bullet> scoping for accessible communication features in 
wheelchair accessible cells has been reduced from 100% to 50%, 
consistent with revised scoping for transient lodging facilities.

234  Accessible Residential Facilities

    The Board has added new scoping requirements for accessible 
residential housing covered by the ADA. This section requires that at 
least 5% (but no less than one) of the total number of dwelling units 
be accessible. An additional 2% minimum of the dwelling units are 
required to be equipped with accessible communication features but are 
not required to be wheelchair accessible. Dispersion of accessible 
units is required among the various types of units provided so that 
people with disabilities have choices of dwelling units comparable to 
and integrated with those available to other residents.

Part II: ABA Application and Scoping

    This part provides application and scoping requirements for 
facilities covered by the ABA. The Board develops and maintains minimum 
guidelines for buildings and facilities covered by the ABA 
<SUP>10</SUP>. These guidelines serve as the basis for standards issued 
by four standard-setting Federal agencies: the General Services 
Administration (GSA), the Department of Defense (DOD), the Department 
of Housing and Urban Development (HUD), and the U.S. Postal Service 
(USPS). Representatives of these agencies, as well as those of other 
departments, serve as Federal members of the Board. In this capacity, 
these agencies have coordinated closely with the Board in updating the 
ABA accessibility guidelines.
---------------------------------------------------------------------------

    \10\ The ABA covers: (1) facilities constructed or altered by or 
on behalf of the United States; (2) facilities leased in whole or in 
part by the United States; (3) facilities financed in whole or in 
part by a grant or loan made by the United States, if such building 
or facility is subject to standards for design, construction, or 
alteration issued under authority of the law authorizing such grant 
or loan; and (4) facilities to be constructed under authority of the 
National Capital Transportation Act of 1965, or title III of the 
Washington Metropolitan Area Transit Regulation Compact. 
Notwithstanding the above, the ABA does not cover: a privately owned 
residential structure not leased by the Government for subsidized 
housing programs; or, any building or facility on a military 
installation designed and constructed primarily for use by military 
personnel without disabilities. The current ABA standard exempts 
various military facilities consistent with the statute (UFAS 
4.1.4(2)); this exclusion has not been retained in the revised 
guidelines as it is more appropriately contained in the implementing 
regulations issued by the DOD and the other standard-setting 
agencies.
---------------------------------------------------------------------------

    The Board has based the ABA scoping and application sections on the 
revised ADA scoping and application sections of Part I. This will 
ensure greater consistency between both scoping documents and will 
serve to establish greater uniformity in the level of access among 
facilities covered by the ADA or the ABA. The Board previously adopted 
a resolution introduced by GSA to ensure that the level of 
accessibility established for federally funded facilities in this 
rulemaking meets or exceeds that proposed for the private sector and 
State and local government sectors under the ADA. To this end, 
differences or departures from the ADA scoping and application sections 
have been minimized. Most changes are necessary due to differences 
between the ABA and ADA statutes and regulations issued under them. For 
example, the ABA covers facilities leased by Federal agencies and the 
guidelines for the ABA reflect this statutory difference. The 
guidelines for the ADA and ABA are being consolidated in one part of 
the Code of Federal Regulations (36 CFR Part 1191). The following 
discussion explains substantive differences from the application and 
scoping requirements for facilities covered by the ADA as discussed in 
Part I.

F103  Modifications and Waivers

    The ABA recognizes a process under which covered entities may 
request a modification or waiver of the applicable standard. The 
standard-setting agencies may grant a modification or waiver upon a 
case-by-case determination that it is clearly necessary. This 
modification and waiver process is recognized in section F103 as a 
substitute to the provision for ``equivalent facilitation'' in section 
103 provided for facilities subject to the ADA.

F106  Definitions

    Several defined terms in section F106.5 differ from those in the 
ADA application section. These include ``dwelling unit'' and 
``transient lodging'' which have been simplified and made mutually 
exclusive. Definitions for ``joint use'' and ``lease'' are included 
that pertain to provisions specific to the ABA covering leased 
facilities. Definitions of ``private building or facility'' and 
``public building or facility'' are not included because these terms 
are used to distinguish between places of public accommodation and 
commercial facilities covered by title III of the ADA (private) and 
State and local government facilities covered by title II of the ADA 
(public).

F202  Existing Buildings and Facilities

F202.2  Additions

    Section F202.2 addresses additions to existing facilities and 
provides specific criteria for accessible routes, entrances, and toilet 
and bathing facilities that derive from the current standard, UFAS. 
These provisions have been retained but are not provided in the ADA 
scoping document. Provisions in this section for public pay telephones 
and drinking fountains have been included for consistency with a 
requirement in the ADA scoping document for an accessible path of 
travel for certain additions (202.2).

F202.6  Leases

    The ABA requires access to facilities leased by Federal agencies. 
Section F202.6 contains scoping requirements for facilities that are 
newly leased by the Federal government, including new leases for 
facilities previously occupied by the Federal government. The 
negotiation of a new lease occurs when (1) the Federal government 
leases a facility that it did not occupy previously; or (2) an existing 
term ends and a new lease is negotiated for continued occupancy. The 
unilateral exercise of an option which is included

[[Page 62261]]

as one of the terms of a preexisting lease is not considered the 
negotiation of a new lease. Negotiations which do not result in a lease 
agreement are not covered by this section. Provisions in this section 
address joint-use areas, accessible routes, toilet and bathing 
facilities, parking, and other elements and spaces. Corresponding 
changes concerning coverage of leased facilities appear in the sections 
stating the purpose (F101) and the overall scope of the guidelines 
(F201.1).

F234  Housing

    The proposed scoping provisions for dwelling units covered by the 
ABA are identical to those proposed for the ADA. However, UFAS 4.1.4(3) 
effectively allows the Department of Defense the option to modify units 
when the need arises as opposed to providing accessible units at the 
time of construction and to do so on an installation-by-installation 
basis. This flexibility allows the military departments to leave 
families without disabilities in accessible units and to modify units 
to suit the needs of families with disabilities.
    Question 17: Should a similar exception be included in the revised 
guidelines that would permit accessible dwelling units under control of 
the Department of Defense to be designed to be readily and easily 
modifiable to be accessible provided that modifications are 
accomplished on a first priority basis when a requirement is 
identified? Also, should a similar exception be provided that permits 
provision of access on an installation-by-installation basis?

Other Differences from ADAAG

    Certain provisions or exceptions in the ADA scoping section 
applicable only to the private sector (i.e., places of public 
accommodation and commercial facilities) or recognized only by the ADA 
are not included in the ABA scoping section. These include:
    <bullet> an exception that permits a limited level of access to 
work areas for approach, entry and exit and that does not otherwise 
require the area itself to be accessible (203.3);
    <bullet> an exception from the requirement for an accessible route 
in private multi-level buildings and facilities that are less than 
three stories or that have less than 3,000 square feet per floor 
(206.2.3, Exception 1);
    <bullet> TTY scoping provisions specific to private buildings 
(217.4.2.2 and 217.4.3.2); and
    <bullet> an ADA exception from the requirement for accessible guest 
rooms for certain places of lodging that have five or fewer rooms for 
rent or hire (224.1, Exception).

Part III: Technical Requirements

    Part III provides technical requirements (Chapters 3 through 11) 
that are referenced by the ADA and ABA application and scoping 
documents. These requirements are based on recommendations from the 
advisory committee unless otherwise noted. The following analysis 
describes substantive differences between the revised guidelines and 
ADAAG technical requirements.
Chapter 3: Building Blocks
    Chapter 3 contains basic technical requirements considered to be 
the ``building blocks'' for accessibility as established by the 
guidelines. All sections of this chapter correspond to ADAAG 
requirements. They are referenced by scoping provisions in Chapter 2 
and by the technical chapters (4 through 11).

302  Floor or Ground Surfaces

    This section is substantively similar to ADAAG 4.5. Section 302.1 
requires floor or ground surfaces to be ``stable, firm, and slip 
resistant'' as does ADAAG 4.5.1. ADAAG however provides scoping 
language in this requirement that has not been included in 302.1. 
Instead, other technical sections, such as those for walking surfaces 
(403), ramps (405), and stairways (504) reference this requirement. 
ADAAG also applies the requirement generally to ``accessible rooms and 
spaces,'' a requirement that has not been retained in the revised 
guidelines because nearly all rooms and spaces must be accessible.
    Section 302.2 which addresses carpet is consistent with ADAAG 
4.5.3. Section 302.3 covers openings and derives from ADAAG 4.5.4. This 
requirement has been revised to cover ``openings'' instead of 
``gratings'' in order to cover all types of openings in a floor or 
ground surface that would be an impediment to mobility in addition to 
gratings, such as expansion joints and spaced wood decking. 
Clarification is also provided that this requirement does not apply to 
elevators or wheelchair lifts where an opening between the car and the 
floor level is necessary to operate the elevator.

303  Changes in Level

    This section is the same as ADAAG 4.5.2 except for editorial 
changes.

304  Wheelchair Turning Space

    Consistent with ADAAG 4.2.3, this section recognizes circular and 
T-shaped turning space and provides textual description of the size and 
dimensions for each contained in ADAAG Figure 3. Unlike ADAAG, this 
section clarifies that elements with knee and toe clearance can overlap 
turning space. It explains the extent to which overlap is permitted, 
limiting it to one segment of the T-shaped space. The overlap of 
circular turning space is not specifically limited although the maximum 
depth for knee and toe space has been increased from 19 to 25 inches as 
indicated in section 306. Additionally, clarification is provided that, 
in general, doors can swing into the turning space but that changes in 
level or slopes greater than 1:48 are not permitted within the space.

305  Clear Floor or Ground Space

    This section is consistent with ADAAG 4.2.4 and provides 
clarification that changes in level and slopes greater than 1:48 are 
not permitted within the clear floor or ground space.

306  Knee and Toe Clearance

    The revised guidelines provide specifications for knee and toe 
clearances as a basic ``building block.'' The specifications correspond 
to knee and toe clearances provided in ADAAG specifically for plumbed 
fixtures, including drinking fountains (4.15) and lavatories (4.19). 
The new format recognizes these clearances for other elements as well, 
such as tables and counters. There are two substantive changes. The 
maximum depth for the knee and toe space specified in 306.2.2 and 
306.3.2 has been increased from 19 to 25 inches. The advisory committee 
recommended this change for consistency with an ADAAG specification in 
Figure 5(b) for obstructed reaches which recognizes a 25 inch maximum 
depth. The other change concerns removal of the ADAAG specification of 
a 29 inch minimum apron clearance at lavatories, which the advisory 
committee considered ineffective without a minimum depth. Further 
detail has been added about the clearance between the knee and toe 
space; this clearance is permitted to be reduced at a rate of 1 inch 
for each 6 inches in height. The advisory committee's intent was to 
describe in text the sloping profile of the space between knees and 
toes in ADAAG Figures 27(a) and 31.

307  Protruding Objects

    This section is substantively consistent with ADAAG 4.4 except for 
the addition of three exceptions. An exception to the requirement for 
protrusion limits in 307.2 permits handrails serving stairs and ramps 
to

[[Page 62262]]

protrude 4\1/2\ inches maximum from wall surfaces. This was recommended 
by the advisory committee to prevent conflict with model code 
requirements. An exception to the requirement for post-mounted objects 
in 307.3 exempts the sloping portions of ramp or stair handrails. The 
Board has added an exception to the requirement for vertical clearances 
in 307.4 that permits door closers and door stops to encroach up to 2 
inches into the 80 inch minimum clearance. This exception clarifies a 
common question concerning standard size doors. This section uses the 
terms ``wall'' and ``post'' to provide a reference point for measuring 
protrusions. The terms are to be liberally construed. For example, a 
partition or a column is understood to provide a wall surface.

308  Reach Ranges

    This section is consistent with forward and side reach range 
requirements in ADAAG 4.2.5 and 4.2.6, including obstructed reaches. 
Forward reach ranges are 48 inches maximum and 15 inches minimum; side 
reach ranges are 54 inches maximum and 9 inches minimum. The advisory 
committee recommended that the side reach range, including obstructed 
reaches, be changed to those required for forward reaches. This 
recommendation was based on a report from the Little People of America 
which considered the 54 inch height beyond the reach for many people of 
short stature. The advisory committee also considered the 48 inch 
maximum for side reaches as preferable for people who use wheelchairs.
    The Board has not included this recommended change in the proposed 
rule because it believes a change to this long-standing provision 
requires further research. The reach range specifications apply to a 
wide variety of controls and elements, from gasoline dispensers to ATMs 
to information kiosks to off-street parking meters and self service 
parking payment and ticket machines. The Board believes information on 
the impact of the recommended change on these and other types of 
elements should be developed before proposing any reduction in the 
maximum side reach height. However, the most recent draft of the ICC/
ANSI A117.1-1998 does lower the high side reach to 48 inches, 
therefore, new codes based on this standard will be more stringent in 
this regard. The experience of the building industry and people with 
disabilities will provide an invaluable resource in subsequent 
revisions of ADAAG.

309  Operable Parts

    Requirements for operable parts are consistent with those for 
controls and operating mechanisms in ADAAG 4.27.
    Section 309.4 specifies that operable parts not require more than 5 
pounds of force for operation. This long-standing specification appears 
sufficient for controls operated by the hand, such as door hardware, 
faucets, and push plates. However, anecdotal information indicates that 
a 5 pound maximum is too high for controls activated by a single 
finger, such as elevator call and control panel buttons, platform lift 
controls, telephone key pads, function keys for ATMs and fare machines, 
and controls for emergency communication equipment in areas of refuge, 
among others. Usability of such controls also may be affected by how 
far the button or key must be depressed (i.e., the stroke depth) for 
activation. Information indicates that most control buttons of keys can 
meet a 3.5 maximum pounds of force and a maximum stroke depth of \1/10\ 
inches. The Board is considering including these specifications in the 
final rule based on responses to the following questions.
    Question 18: Comment is sought on whether a maximum 3.5 pounds of 
force and a maximum \1/10\ inch stroke depth provide sufficient 
accessibility for the use of operable parts activated by a single 
finger.
    Question 19: The Board seeks information on any types of operable 
parts covered by the revised guidelines that cannot meet, or would be 
adversely affected by, a maximum 3.5 pounds activation force and 
maximum \1/10\ inch stroke depth.
Chapter 4: Accessible Routes and Accessible Means of Egress
    In the revised guidelines, all components of accessible routes and 
means of egress have been combined into one chapter, including walking 
surfaces, doors, ramps, elevators, wheelchair lifts, and areas of 
refuge. Section 402 indicates that accessible routes consist of these 
components.

403 Walking Surfaces

    ``Walking Surfaces'' is a new term that has been introduced to 
refer to the portion of interior or exterior accessible routes existing 
between doors and doorways, ramps, elevators, or lifts. The 
requirements for walking surfaces derive from specifications for 
accessible routes in ADAAG 4.3 and are substantively the same in 
addressing floor or ground surfaces, slope, changes in level, clear 
width (including for turns around objects), wheelchair passing space, 
and protruding objects. There are three changes from technical 
requirements in ADAAG:
    <bullet> the maximum cross slope has been changed from 1:50 to 1:48 
throughout the revised guidelines for consistency with model building 
codes (403.3);
    <bullet> a new specification has been added that requires a minimum 
linear separation of 48 inches between permitted reductions in the 36 
inch minimum clear width (403.5); and
    <bullet> for turns around objects, clarification has been added 
that, where a 60 inch minimum width at a turn is provided, the clear 
width of the connecting route can be 36 inches minimum instead of 42 
inches minimum because 60 inches permits 360 degree maneuvering 
(403.5.1).
    Question 20: The revised guidelines, like the current ADAAG, 
provide technical criteria for handrails along stairs and ramps. 
Section 505 of the revised guidelines provide requirements for 
continuity, height, clearance, gripping surface, cross section, 
fittings, and extensions. Handrails provided at other locations, such 
as along corridors in medical care facilities and airports, are not 
subject to these criteria except at stairs and ramps. The Board seeks 
comment on whether handrails, where provided along circulation paths 
without a slope or steps, should be subject to the technical 
requirements in 505. Such a requirement may be included in the final 
rule.

404  Doors and Doorways

    This section provides requirements for doors and doorways which 
correspond to those in ADAAG 4.13. Requirements for entrances in ADAAG 
4.14, which are basically scoping in nature, have been relocated to 
Chapter 2 as part of scoping provisions for accessible routes (206.4).
    Like ADAAG, requirements are provided for manual doors (404.2) and 
automatic doors (404.3). The Board has provided an exception in 404.2 
for manual doors, doorways, and gates operated only by security 
personnel under which compliance with requirements for door hardware, 
closing speed, and door opening forces is not required. This exception 
is based on one provided in ADAAG for judicial facilities and detention 
and correctional facilities. For consistency, the Board has made this 
exception generally applicable to all facilities. Security personnel 
must have sole control of doors that are eligible for this exception. 
It would not be acceptable for security personnel to operate the doors 
for people with disabilities while others have independent access. A 
similar

[[Page 62263]]

exception is provided for automatic doors in 404.3.
    Section 404.2.3 addresses clear width and is different from ADAAG 
in several respects. An exception in ADAAG 4.13.5 that allows a 20 inch 
minimum clearance at doors not requiring full user passage has been 
removed because such doors are not part of an accessible route. 
Clarification has been provided on the protrusion of door hardware into 
the clear width. ADAAG indicates that the clear width is to be measured 
to the face of the door. However, the clear width requirement has been 
misinterpreted as prohibiting certain door hardware, such as panic 
bars, from protruding into this clearance. Language has been added 
which prohibits projections into the minimum clear width at heights 
below 34 inches; above this height (up to 80 inches), projections of 4 
inches maximum are allowed. The Board has also editorially revised an 
exception that allows the latch side stop to protrude up to \5/8\ inch 
in alterations (404.2.3 Exception). In ADAAG, this exception is limited 
to cases of ``technical infeasibility.'' The Board has removed this 
qualification in this and other exceptions for alterations as noted in 
section 202 above.
    Section 404.2.4 specifies door maneuvering clearances which are 
consistent with ADAAG 4.13.6. However, ADAAG provides these 
specifications through illustration (Figure 25) and the revised 
guidelines, which provide all requirements in written text, use tables 
to provide this information (Tables 404.2.4.1 and 4042.4.2). 
Clarification is also provided for recessed doors. ADAAG Figure 25 
requires that doors in alcoves provide clearance for a forward 
approach. This provision has led to questions about what constitutes an 
``alcove.'' In 404.2.4.3, this requirement has been changed to apply 
specifically to ``recessed doors where the plane of the doorway is 
offset more than 8 inches from any obstruction within 18 inches 
measured laterally on the latch side of the door.''
    Section 404.2.5 covers thresholds. A provision in ADAAG 413.8 that 
allows thresholds \3/4\ inch high maximum at exterior sliding doors has 
been removed because products are available that meet the \1/2\ inch 
high maximum specified for all other doors. An exception that permits 
in alterations a \3/4\ inch maximum threshold if beveled on both sides 
has been retained.
    In section 404.2.7, which covers door hardware, a minimum mounting 
height for door hardware (34 inches) has been added. This height 
corresponds with revisions to the required clear width at doors to 
clarify that limited projections into the clear width are acceptable 
above this height. The maximum height (48 inches) is consistent with 
ADAAG 4.13.9. The advisory committee also recommended an exception that 
would permit any location for locks used only for security purposes and 
not for normal operation. This would address certain doors that 
typically have locks located outside the specified reach range, such as 
doors without stiles that lock at the bottom edge. The Board has 
included an exception but has further refined its application to 
``existing locks at existing glazed doors without stiles, existing 
overhead rolling doors or grilles, and similar existing doors or 
grilles that are designed with locks that are activated only at the top 
or bottom rail.'' The Board has limited this exception to existing 
doors or grilles because design solutions for accessible doors and 
gates are available in new construction.
    Closing speed is addressed by section 404.2.8 and corresponds to 
ADAAG 4.13.10. The required minimum closing speed for door closers is 
generally consistent with ADAAG, although the values differ due to 
changes in the measuring points. This revision was recommended by the 
advisory committee for consistency with the ICC/ANSI A117.1 standard. 
This section also includes a new provision for spring hinges, which 
offer little opening resistance and closing forces in the 1 to 2 pounds 
of force range. The requirement specifies that such hinges be adjusted 
so as to close from an open position of 70 degrees no faster than 1.5 
seconds.
    Two new provisions are provided for door surfaces and vision lites. 
Section 404.2.10 requires that swing doors have a smooth surface on the 
push side that extends the full width of the door. This provision 
derives from the ANSI A117.1-1992 standard and is intended to permit 
wheelchair footrests to be used in pushing open doors without risking 
entrapment on the stile. Exceptions to this requirement are provided 
for certain types of doors, such as tempered glass doors without 
stiles. Section 404.2.11 requires that, where vision panels in or 
adjacent to doors are provided, the bottom of at least one glazed panel 
be no higher than 43 inches from the floor for access to people using 
wheelchairs or who are of short stature. This height permits hardware 
to remain at industry standard locations. The Board has added an 
exception for vision lites that are more than 66 inches from the floor 
or ground, measured to the lowest part.
    Section 404.3 addresses automatic doors. As in ADAAG 4.13.12, full-
powered, low-energy, and power-assisted doors are addressed, and the 
industry standards (ANSI/BHMA 156.10 and 156.19) are referenced. The 
revised guidelines, as indicated in section 105.2, reference the most 
recent version of these standards (1996). Requirements in ADAAG 4.13.12 
for door opening speed and forces have been removed since they are 
addressed by the referenced standards. Other differences from ADAAG 
include:
    <bullet> clarification that the required 32 inch minimum clear 
opening applies to both power-on and power-failure modes and that the 
clear width for automatic doors is based on the clear opening provided 
by all leafs when simultaneously in the open position (404.3.1);
    <bullet> addition of a requirement that maneuvering clearances 
specified for swing doors be provided at power-assisted doors since 
such doors are manually operated (404.3.2);
    <bullet> addition of a requirement that labels and warning signs 
for automatic doors meet requirements in section 703.4 for non-tactile 
signage (404.3.6); and
    <bullet> addition of a requirement by the Board that the clear 
break out opening for swinging or sliding automatic doors be at least 
32 inches in emergency mode so that an accessible route through them is 
maintained in emergencies (404.3.7).

405  Ramps

    Requirements for ramps are based on those in ADAAG 4.8. Differences 
from ADAAG concern:
    <bullet> removal of the requirement that ``the least possible 
[running] slope'' be used for any ramp, which is considered too vague 
from a compliance standpoint (the 1:12 maximum slope has been retained) 
(405.2);
    <bullet> the maximum cross slope has been changed from 1:50 to 1:48 
for consistency with model building codes (405.3);
    <bullet> clarification is provided that changes in level other than 
the running and cross slopes are not permitted on ramp runs (405.4);
    <bullet> clarification is added that the required clear width (36 
inches minimum) is measured between the leading edge of handrails 
(405.5);
    <bullet> clarification is provided that ramp landings cannot slope 
more than 1:48 or have any other change in level (405.7.1) and that 
ramp landings and door maneuvering clearances can overlap (405.7.5); 
and
    <bullet> revision of the requirement for handrails so that it 
applies to any ramp with a rise greater than 6 inches but not to those 
with a horizontal projection

[[Page 62264]]

greater than 72 inches since it can discourage shallower slopes on 
short ramps (405.8).
    In addition, further specification is provided for edge protection 
in section 405.9. This section is clearer than ADAAG 4.8.7 in 
recognizing surface extensions beyond handrails (12 inches minimum) and 
in recognizing guards, curbs, or barriers that prevent passage of a 4 
inch diameter sphere at the ground or floor surface. Exceptions are 
provided to clarify that edge protection is not required on curb ramps 
with flared sides or returned curbs, at stair or ramp openings at 
landings, or at landings that have a maximum \1/2\ inch drop-off within 
10 inches horizontally of the minimum landing area.

406  Curb Ramps

    Requirements for curb ramps in the revised guidelines are 
consistent with those in ADAAG 4.7. Revisions made to requirements for 
ramps, such as the clarification that changes in level other than the 
running and cross slope are prohibited, apply to curb ramps as well. 
ADAAG originally contained a requirement in 4.7.7 that curb ramp 
surfaces have a raised distinctive pattern of truncated domes to serve 
as a warning detectable by cane or underfoot to alert people with 
vision impairments of the transition to vehicular ways. This warning 
was required for curb ramps in the belief that their sloped surfaces 
removed the tactile cue provided by the straight drop off of a curb. In 
response to concerns about the specification, which was based on 
research, the availability of complying products, proper maintenance 
such as snow and ice removal, usefulness, and safety concerns, the 
Board suspended this requirement jointly with the departments of 
Justice and Transportation in July 1994. This action suspended the 
requirements for detectable warnings at curb ramps, hazardous vehicular 
areas, and reflecting pools until July 26, 1996, pending the results of 
a research project on the need for detectable warnings at these 
locations and at vehicular-pedestrian intersections in the public 
right-of-way.
    The research project showed that vehicular-pedestrian intersections 
are very complex environments and that pedestrians who are blind or 
visually impaired use a combination of cues to detect intersections. 
The research project found that detectable warnings helped some 
pedestrians who are blind or visually impaired locate and identify curb 
ramps. However, the detectable warnings had only a modest impact on 
overall performance because, in their absence, pedestrians who are 
blind or visually impaired used other cues that might be available to 
detect the intersection. The research project indicated that there may 
be a need for additional cues at some types of intersections. The 
research project did not identify the specific conditions where such 
cues should be provided. The research project suggested that other 
technologies, which may be less costly and equally or more effective 
than detectable warnings, be explored for providing information about 
intersections.
    In 1996, the Access Board and the departments of Justice and 
Transportation extended the suspension of the detectable warning 
requirements to July 26, 1998, to allow the Board's ADAAG Review 
Advisory Committee to conduct its review of ADAAG and to make 
recommendations for revising and updating the document. The suspension 
has been extended to July 26, 2001. The advisory committee recommended 
that the requirement for detectable warnings at platform edges in 
transportation facilities be retained. The advisory committee also made 
specific recommendations for permitting equivalent tactile surfaces, 
and technology or other means to provide equivalent detectability of 
the platform edge as an alternative to the truncated dome surface (see 
discussion at section 705). The advisory committee did not make any 
recommendations regarding the provision of detectable warnings at other 
locations within a site. The advisory committee suggested that the 
appropriateness of providing detectable warnings at vehicular-
pedestrian intersections in the public right-of-way should be 
established first, and the application to other locations within a site 
should be considered afterwards. The Board has not included a 
requirement for detectable warnings within a site (i.e., at hazardous 
vehicular areas or reflecting pools) or at curb ramps.
    Section 406.7 addresses curb ramps provided at pedestrian islands 
which is consistent with ADAAG 4.7.11 and requires clear floor space at 
the top of ramps. The Board has added further detail on the width and 
location of this space relative to the curb ramp. A requirement in 
ADAAG 4.7.8 that curb ramps be located or protected so as not to be 
obstructed by parked vehicles has been removed because it is not always 
possible to prevent such obstruction solely through curb ramp design; 
operational factors, such as local traffic laws and their enforcement 
are also a key factor.

407  Elevators

    Requirements for passenger elevators in ADAAG 4.10 are updated in 
section 407. Elevators must meet the industry safety code, ASME/ANSI 
A17.1, according to the most recent version (1993 with 1994 and 1995 
addenda) as indicated in section 105.2. In addition to the types of 
passenger elevators recognized by ADAAG, the revised guidelines provide 
technical criteria for two new types of elevators destination-oriented 
elevators in 407.3 and limited-use/ limited-application (LULA) 
elevators in 407.4. A new subsection, 407.5, is also provided for 
existing elevators that are altered.
    Section 407.2 covers passenger elevators currently addressed by 
ADAAG. A reference in ADAAG 4.10.1 to ``combination passenger and 
freight elevators'' has been removed because the type of elevator this 
was intended to cover is generally considered a ``passenger elevator'' 
by the ASME Elevator Safety Code, which does not address 
``combination'' elevators.
    A change is made to specifications for car size in section 407.2.8. 
ADAAG 4.10.9 recognizes two standard car configurations based on early 
industry conventions and provides a general performance standard 
requiring that users be able to enter the car, maneuver within reach of 
the controls, and exit from the car. The advisory committee considered 
these specifications too restrictive since they did not specify other 
standard configurations, such as the elongated hospital-type car, that 
are considered to meet the general performance standard. In Table 
407.2.8, a greater variety of inner car dimensions are permitted. In 
addition to those specified by ADAAG, this table also permits ca
