The Americans with Disabilities Act has given new hope to those who are physically or psychologically challenged. When thinking of accessibility issues, many think only of architectural barriers. Chemical, perceptual, auditory, visual, cognitive, and psychosocial issues as well as physical and functional barriers also demand attention. Multidisciplinary design teams, including persons with disabilities, utilizing human factors methodology offer a new model for creating accessible environments. An accessibility audit for team use is presented. Modification for vision and hearing loss, products, an accessible single-family dwelling, and multi-family federally financed housing are discussed.
