What are the laws about services animals that apply to my business?

The U.S. Department of Justice issued revised Americans with Disabilities Act (ADA) regulations that took effect on March 15, 2011.  Under the revised ADA, public and commercial facilities such as restaurants, hotels, retail stores, taxicabs, theaters, concert halls, and sports facilities must permit service animals to accompany people with disabilities in all areas where members of the public are allowed to go.
