Which ADA Title II website date applies to us?

By Matt Kerr·Published 7 November 2026

Choose the kind of public body and, where asked, its census population. The answer comes from the rule as it stands on 7 November 2026: 26 April 2027 for 50,000 people or more, 26 April 2028 for fewer and for every special district.

Four examples

• A township of 8,400 people. Under 50,000, so 26 April 2028.
• A county of 120,000 people. 50,000 or more, so 26 April 2027. Its townships and villages each go by their own population, not the county’s.
• A fire district or a library district. A special district, so 26 April 2028, even if it serves a large city.
• A transit authority set up by two cities. It has no census figure of its own, so it uses the two cities’ populations added together: 31,000 and 26,000 make 57,000, so 26 April 2027.

What has to meet the standard on that date

Your web pages and any mobile app, including what vendors run for you on your site, such as payment, permit or booking pages. Documents count too: PDFs, Word files, slides and spreadsheets you post from that date on, and older ones people still use to apply for something. Five kinds of content are exempt, among them older documents that are only kept for the record and what members of the public post. The explainer lists all five.

Where to find the population

The rule uses the Census Bureau’s figure from the most recent decennial census; data.census.gov shows it for every county, city, town and township. A school district uses the Census Bureau’s school district estimate. The full explainer has the 5 exceptions and the sources.

Nothing you type leaves your browser, and the checker stores nothing. It covers the date only; whether a page meets the standard is a separate check.

This page explains the rule in plain words. It is not legal advice; for a decision about your own body, ask your attorney.
