Title II focuses on providing accessibility to programs, not buildings, and therefore does not require public entities to remove barriers from each facility. Structural changes are not required if accessibility can be achieved by other means. Design issues that should be addressed in correctional facilities include doors, door closers, toilet and lavatory fixtures, cell desks and dayroom tables, elevator controls, door thresholds, telephones, and signs. Facility areas affected in specific ways include the central control room, security vestibules, housing areas, medical areas, visiting areas, indoor and outdoor exercise areas, food service areas, laundry facilities, administrative and public reception areas, and staff areas.
