Accessibility laws, standards & resources.

Find the rule that applies to you, and the source that proves it.

Accessibility law in the United States is not one rule. Which standard you have to meet, and by when, depends on who you are — a state or local government, a federal agency, a vendor selling to one, an organization that takes federal funding, or a private business.

Everything below is grouped by that question. Each group starts with the primary source, the regulation itself or the agency that enforces it, and ends with our own plain-language explainers for where the official version is heavy going.

Nothing here is sponsored. We are not paid to recommend any tool, product or vendor on this page.
