42 U.S.C. § 12183
Requires facilities designed and constructed for first occupancy later than January 26, 1993 that are public accommodations or commercial facilities to be readily accessible to and usable by individuals with disabilities, except where structurally impracticable. Alterations affecting usability must, to the maximum extent feasible, make the altered portions accessible, and alterations affecting an area containing a primary function trigger an accessible path of travel to that area (including the bathrooms, telephones, and drinking fountains serving it) unless that cost is disproportionate to the overall alterations. The provision does not require installing an elevator in facilities under three stories or under 3,000 square feet per story, except for shopping centers, shopping malls, the professional office of a health care provider, or categories the Attorney General determines require elevators.
