This report presents the final recommendations, in the form of a new set of guidelines, of a federal advisory committee concerning revisions to the Americans with Disabilities Act Accessibility Guidelines (ADAAG). The guidelines provide scoping and technical requirements for the design, construction, and alteration of sites, facilities, buildings, and elements for accessibility by individuals with disabilities. The guidelines are grouped into 10 chapters which address: (1) definitions of terms; (2) scoping requirements (such as passenger loading zones, stairways, signs, sinks, and transportation facilities); (3) building blocks (such as wheelchair turning space, protruding objects, and reach ranges); (4) accessible routes and accessible means of egress (such as walking surfaces, ramps, and wheelchair lifts); (5) general site and building elements (such as parking spaces, stairways, and handrails); (6) plumbing elements and facilities (such as toilet and bathing rooms, bathtubs, and laundry equipment); (7) communication elements and features (such as fire alarm systems, assistive listening systems, and detectable warnings); (8) special rooms and spaces (such as wheelchair spaces in assembly areas, and medical care facility rooms); (9) built-in furnishings and equipment (such as benches and storage); and (10) transportation facilities, such as bus stops and terminals. Recommendations for changes in format of the guidelines are also offered. (DB)
