(a) General rule. All persons are prohibited from bringing animals in or on Federal property for other than official purposes.

(b) Exception. Persons with disabilities, as defined under the Americans with Disabilities Act of 1990, may, consistent with 28 CFR 35.136, bring a service animal or miniature horse that is trained to do work or perform tasks for the benefit of that individual. The work or tasks performed by a service animal must be directly related to the individual's disability. Examples of work or tasks include, but are not limited to, assisting individuals who are blind or have low vision with navigation and other tasks, alerting individuals who are deaf or hard of hearing to the presence of people or sounds, providing non-violent protection or rescue work, pulling a wheelchair, assisting an individual during a seizure, alerting individuals to the presence of allergens, retrieving items such as medicine or the telephone, providing physical support and assistance with balance and stability to individuals with mobility disabilities, and helping persons with psychiatric and neurological disabilities by preventing or interrupting impulsive or destructive behaviors. The crime deterrent effects of an animal's presence and the provision of emotional support, well-being, comfort, or companionship do not constitute work or tasks for purposes of the exception in this paragraph (b). Persons with disabilities may be required to state whether the animal is a service animal required because of a disability.
