To be protected by the ADA, one must have a disability or have a relationship or association with an individual with a disability. An individual with a disability is defined by the ADA as a person who has a physical or mental impairment that substantially limits one or more major life activities*, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment (https://www.ada.gov/cguide.htm).
*Major life activities include, but are not limited to: caring for oneself, performing manual tasks, seeing, hearing, eating, sleeping, walking, standing, lifting, bending, speaking, breathing, learning, reading, concentrating, thinking, communicating, and working (https://www.dol.gov/ofccp/regs/compliance/faqs/ADAfaqs.htm).
If you have a disability and experience an access concern, there are measures in place to address the situation. The contact point is dependent on your relationship with the university.
