Does ADA compliance apply to websites?
Yes. Title III of the ADA applies to businesses open to the public, and the Department of Justice says it has consistently taken the position that the ADA applies to the goods and services those businesses offer on the web. There is no exemption for small businesses; religious organizations and private clubs are the main exceptions.
The ADA text does not list technical requirements for websites. For state and local governments, the DOJ's April 2024 Title II rule requires WCAG 2.1 Level AA. For businesses open to the public, the DOJ says it does not have a regulation setting out detailed standards, and that existing technical standards, including WCAG, provide helpful guidance. WCAG 2.1 AA is the standard a GrossiWeb audit tests against.
