First produced in 1991, the Americans with Disabilities Act Guidelines (ADAAG) are guidelines for compliance with the accessibility requirements of the ADA. The ADA is a law that addresses access to the workplace (Title I), state and local government services (Title II), and places of public accommodation and commercial facilities (Title III). It also requires phone companies to provide telecommunications relay services for people who have hearing or speech impairments (Title IV) and miscellaneous instructions for federal agencies that enforce the law (Title V).
On September 15, 2010, the U. S. Department of Justice published new ADA Title II and III regulations and adopted updated design standards called the 2010 Standards for Accessible Design. On and after March 15, 2012, use of the 1990 ADA as it applied to facilities and entities covered by Titles II and III and the 1991 ADAAG (ADA Access Guidelines) standard was no longer permitted for new construction and for alterations of existing elements conducted after that date.
