On March 15, 2012 the new ADA Accessibility Guidelines (called the Standards for Accessible Design or SAD) became mandatory on a national level for newly designed or altered facilities. The Department of Justice enforces the standard in places of public accommodation, commercial facilities and in state or local government facilities.
The new standards represent the first major change to the technical requirements since the ADAAG was first published in 1991. There are substantive changes to the requirements for accessible signage, in both the scoping and technical sections of the standards. Both tactile and visual characters are defined in greater detail, mounting heights for signs have changed and minimum character heights have been determined based on viewing distance. Detailed information is available in these APCO Publications:
• Requirements for Interior Signs
• SignInfo: Summary of Requirements for Interior Signs
• LRV (Light Reflectancy Values) Chart
• Contrast Calculator
• APCO Color Chart
Should you have any questions about signs and the ADA, technical assistance is available directly from the Access Board through their question line: , or by phone at 1 800 872 2253.
