ABA Standards (Federal Facilities)

Federal building

Federal facilities must comply with standards issued under the Architectural Barriers Act (ABA). The ABA applies to facilities designed, built, altered, or leased with Federal funds. Several agencies maintain standards under the ABA according to minimum guidelines established by the Access Board: the General Services Administration (GSA), the U.S. Postal Service (USPS), the Department of Defense (DOD), and the Department of Housing and Urban Development (HUD). Though issued by different agencies, the ABA standards are virtually the same except that the update of HUD's standards for residential facilities is still pending.



The Access Board maintains accessibility guidelines that serve as the minimum baseline for the ABA standards. In its last update, the Board harmonized the ABA guidelines with its guidelines for facilities covered by the ADA 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).
