ADA standards govern the construction and alteration of places of public accommodation, commercial facilities, and state and local government facilities. The Department of Justice (DOJ) maintains ADA standards that apply to all ADA facilities except transportation facilities, which are subject to similar standards issued by the Department of Transportation (DOT). Federal facilities are covered by standards consistent with those of the ADA issued under a different law, the Architectural Barriers Act (ABA).

The latest ADA standards are closely based on the Board's updated ADA and ABA Accessibility Guidelines but include several additional requirements. If using a copy of the Board's widely distributed ADA and ABA guidelines, see the Guide to the Standards.

Regulations
ADA regulations issued by DOJ and DOT provide important information on using the standards:
The Access Board's ADA Accessibility Guidelines (ADAAG) serve as the minimum baseline for the standards. The guidelines and standards are very similar, but only the standards have legal authority. However, the guidance provided here is relevant to the standards. In its last update, the Board harmonized the ADA guidelines with the ABA guidelines for federal facilities and published them jointly. In addition, the Board and the International Code Council (ICC) worked cooperatively to harmonize the ADA and ABA guidelines and access provisions in the International Building Code (IBC).
