Does the ADA apply to State and local governments?

Yes. Title II of the ADA prohibits discrimination against qualified individuals with disabilities in all programs, activities, and services of public entities. It applies to all State and local governments, their departments and agencies, and any other instrumentalities or special purpose districts of State or local governments. This means that not only is a city or state government office covered, but also public schools, community colleges, city police departments, and public libraries. Title II also  clarifies the requirements of section 504 of the Rehabilitation Act of 1973 for public transportation systems that receive Federal financial assistance, and extends coverage to all public entities that provide public transportation, whether or not they receive Federal financial assistance. It establishes detailed standards for the operation of public transit systems, including commuter and intercity rail (AMTRAK).
