Under the ADA, State, and local governments, businesses and non-profit organizations that serve the general public generally must allow service animals to accompany people with disabilities in all areas of the facility where the public is normally allowed to go. For example, in a hospital, it would be inappropriate to exclude a service animal from areas such as patient rooms, clinics, cafeterias or examination rooms. However, it may be appropriate to exclude a service animal from operating rooms or burn units where the animal's presence may compromise a sterile environment.
