1991 Americans with Disabilities Act Accessibility Guidelines (ADAAG)

On July 26, 1991 (exactly one year after the ADA was signed into law), the US Access Board published the 1991 Standards for Accessible Design, otherwise known that the ADA Accessibility Guidelines, or ADAAG. On the same day, those standards were adopted as the legal requirements for compliance with the ADA, meaning that businesses which do not comply with the ADAAG architectural standards are in violation of the Americans with Disabilities Act. The ADAAG contains many of the accessibility features that have become so ubiquitous on the American landscape, including the requirements for accessible parking spaces, ramps, accessible restrooms, and other such features. The 1991 ADAAG was in full force and effect until compliance with the 2010 ADAAG became mandatory. Elements of the 1991 ADAAG that are not superseded by the 2010 version remain in full force and effect, and so the 1991 text remains critically important to understand. The link below is to the full text of the 1991 standards:
