The specifications in the 2009 ANSI Standard make sites, facilities, buildings and elements accessible to and usable by people with such physical disabilities as the inability to walk, difficulty walking, reliance on walking aids, blindness and visual impairment, deafness and hearing impairment, incoordination, reaching and manipulation disabilities, lack of stamina, difficulty interpreting and reacting to sensory information, and extremes of physical size. The intent of the ICC/ANSI A117.1-2009 standard is to allow a person with physical disability to independently get to, enter, and use a site, facility, building, or element.
The previous edition was the 1998 edition. New to the 2009 edition are criteria for elements and fixtures primarily for children's use; enhanced reach range, criteria; transportation facilities; additional provisions for assembly areas; and an addition and rearrangement for accessible dwelling and sleeping units. These new criteria are intended to provide a level of coordination between the accessible provisions of this standard and the Fair Housing Accessibility Guidelines (ADAAG).
The ICC/ANSI A117.1-2009 Standard is intended for adoption by government agencies and by organizations setting model codes to achieve uniformity in the technical design criteria in building codes and other regulations.
