A Guide to the New ADA-ABA Accessibility Guidelines
On July 23, 2004, the U.S. Access Board, an independent Federal agency, issued updated accessibility
guidelines for new or altered facilities covered by Americans with Disabilities Act and the Architectural
Barriers Act. These guidelines address a wide range of facilities in the private and public sectors. Pre-
sented here is an overview of the new guidelines that also highlights significant changes.The following
guidelines (305 and 308) pertain to floor/ground space and reach ranges.
When will the new guidelines take effect?
The Board’s guidelines are not mandatory on the public, but instead serve as the baseline for enforceable
standards (which are) maintained by other Federal agencies. In this respect, they are similar to a model
building code in that they are not required to be followed except as adopted by an enforcing authority.
Under the ADA, the Department of Justice (and in the case of transit facilities, the Department of Transpor-
tation) are responsible for enforceable standards based on the Board’s guidelines. These agencies will
update their ADA standards based on the new guidelines. In doing so, they will indicate when the new
standards are to be followed. Several other agencies (the General Services Administration, Department of
Defense, Department of Housing and Urban Development, and the U.S. Postal Service) hold a similar
responsibility for standards used to enforce the ABA.
Existing Facilities
The ADA and ABA guidelines cover new construction and planned alterations and generally do not apply
to existing facilities except where altered. Facilities built or altered according to earlier versions of the ADA
or ABA standards will not necessarily have to meet the updated version except where they are subse-
quently altered or renovated. The Department of Justice, which regulates requirements for existing facili-
ties under the ADA, intends to address coverage of facilities built or altered according to the original ADA
standards in its rulemaking to update the standards. It will also address facilities retrofitted under ADA
provisions for existing facilities, such as the requirement for barrier removal in places of public accommo-
dation. With respect to ABA facilities, the Board has clarified in the guidelines that facilities built to earlier
ABA standards are subject to the new requirements only in relation to planned alterations.
