History of Accessible Facility Design  

by the WBDG Accessible Committee

The accessibility movement has common roots with the civil rights movement and the Civil Rights Act of 1964. These roots lie in the structure and implementation of laws dealing with accessibility.

The first nationally recognized accessible design standard was the American National Standards Institute (ANSI) A117.1 Accessible and Usable Buildings and Facilities. Released in 1961, this standard was based upon research done by the University of Illinois and funded by the Easter Seals Research Foundation. It served as an important reference for private entities and local and state governments. In 1974, the standard received federal input when the Department of Housing and Urban Development joined the Secretariat of the committee in charge of the standard.

The ANSI standard issued in 1961 provided rudimentary provisions for walks, parking, entrances and doors, toilet rooms, drinking fountains, public telephones, and elevators.

President Lyndon Johnson signed the ABA into law on August 12, 1968 at his ranch in Texas.

The awareness that many were unable to access buildings prompted the first steps toward accessibility requirements.

President Eisenhower presents Hugo Deffner with the "Handicapped American of the Year" Award in 1957 in recognition of his work to promote accessibility in his community. Minutes before the ceremony, Deffner was unable to enter the building where the ceremony was taking place due to the lack of a ramped entrance. This event helped to spawn the birth of the architectural barriers program after the incident disturbed the President's Committee and they immediately included addressing architectural barriers in their meeting later that same year.


Since 1968, when the Architectural Barriers Act was passed, the federal government has taken steps to address accessibility and its enforcement in facilities designed, built, altered, or leased using certain federal funds.
