ADAAG Manual

GENERAL

Provisions for Adults [2.1]

ADAAG specifications are based on adult dimensions. Specifications for elements used primarily by children have been developed and incorporated into ADAAG (although they are not addressed in this edition of the manual). These optional specifications address drinking fountains, water closets, toilet stalls, lavatories, sinks, and fixed or built-in seating and tables.

Equivalent Facilitation [2.2]

Alternatives to specific requirements that provide equal or greater access are permitted. This provides flexibility for new technologies and innovative designs solutions that may not have been taken into account when ADAAG was developed. Examples of equivalent facilitation are included in the text of ADAAG. The Access Board can provide further guidance on what may be considered equivalent but there is no process for certifying alternative methods except in transit facilities covered by DOT regulations. The responsibility for demonstrating equivalent facilitation in the event of a challenge rests with the covered entity. In the case of transit facilities, the Federal Transit Administration does make official determinations of equivalent facilitation.
