Guidance on Use of the International Symbol of Accessibility Under the Americans with Disabilities Act and the Architectural Barriers Act

Summary

Use of a symbol other than the ISA is permitted under the ADA Standards only if it satisfies the equivalent facilitation provision and under the ABA Standards only if a waiver or modification is issued. Otherwise, where the ADA or ABA Standards require accessible spaces or elements to be identified by the ISA, the ISA must be used even where a state or local code or regulation specifies a different symbol. Those who are interested in implementing an alternative symbol of accessibility are encouraged to contact the ISO’s Technical Committee 145 on Graphic Symbols which maintains the graphic symbol standards.
