Guide to ADA Standards

This guide explains requirements in the current editions of the ADA Standards issued by the Department of Justice (DOJ) and the Department of Transportation (DOT). It was developed by the U.S. Access Board in cooperation with DOJ and DOT. It is important to use this guide along with a complete copy of the ADA Standards as it explains, but does not contain or reprint, the text of the ADA Standards. DOJ updated its ADA Standards in 2010, which are referred to as the 2010 ADA Standards for Accessible Design. These standards, which replace the original ADA Standards DOJ issued in 1991, became mandatory for newly constructed and altered facilities as of March 15, 2012. DOJ’s ADA Standards apply to all facilities covered by the ADA except public transit facilities.
