The purpose of the ADA is to: (1) provide a clear and comprehensive national mandate for the elimination of discrimination against individuals with disabilities; (2) provide a clear, strong, consistent, enforceable standard addressing discrimination against individuals with disabilities; (3) ensure that the Federal Government plays a central role in enforcing the standards established in this chapter on behalf of individuals with disabilities; and (4) invoke the sweep of congressional authority, including the power to enforce the fourteenth amendment and to regulate commerce, in order to address the major areas of discrimination faced day-to-day by people with disabilities.
The Act has subchapters or titles: Title I covers employment; Title II covers public services; Title III covers privately operated public accommodations and transportation services; Title IV covers telecommunications relay services; and Title V covers miscellaneous provisions.
Title III of the ADA requires public buildings meet minimum standards and make reasonable accommodations for disabled persons. Multifamily dwellings may require an ADA review prior to rehabilitation design.
