This chapter helps the reader to understand the history of the Americans with Disabilities Act (ADA), specific components of the ADA and how the ADA provides resources to older adults and people with disabilities. The ADA, while groundbreaking, was not initially intended for people with disabilities rather than for older adults. As time progressed, however, the benefits of the ADA were much more far-reaching than originally intended, especially for aging adults with disabilities. The individual titles of the ADA have had some dramatically positive and specific impact for older adults wishing to remain in their homes or in their communities as long as possible. Although the ADA is still in its young adulthood, the benefits of the ADA have only grown as new and further linkages, such as the ADRCs, have developed in all regions of the United States.
