Accessibility

What does ADA compliance mean for a website?

What the ADA means for websites in 2026: who it covers, the WCAG standard courts look to, the delayed government deadlines, and what to do now.

ADA compliance for a website means making it accessible to people with disabilities under the Americans with Disabilities Act. For state and local governments, a Justice Department rule requires WCAG 2.1 AA, with deadlines now in April 2027 and April 2028. For businesses, there is no specific web regulation, but courts apply the ADA and usually measure against WCAG.

What the ADA says about websites

The ADA, passed in 1990, prohibits discrimination against people with disabilities. It does not mention websites. Two parts of it matter online:

  • Title II covers state and local governments, including public schools, universities, courts and transit.
  • Title III covers businesses open to the public, called public accommodations, such as shops, restaurants, hotels and service providers.

Government websites: Title II

In 2024 the Justice Department published a rule requiring Title II websites and mobile apps to meet WCAG 2.1 Level AA. In April 2026 it published an interim final rule extending the deadlines by one year:

  • Public entities serving 50,000 people or more: April 26, 2027.
  • Smaller entities and special districts: April 26, 2028. The technical standard did not change.

Business websites: Title III

There is no Justice Department regulation setting a technical standard for business websites, and that rulemaking is paused. The Department's position is that the ADA still applies to businesses' online services, and private lawsuits continue in large numbers. Courts and settlements usually measure accessibility against WCAG 2.1 AA, so that is the practical target.

Nothing here is legal advice. Whether and how the ADA applies to your organization depends on facts a lawyer should review.

What to do

  • Test your site against WCAG 2.1 AA, or 2.2 AA, with automated checks and manual keyboard and screen reader testing.
  • Fix the most common barriers first: contrast, missing alt text, unlabeled forms, keyboard traps and missing captions.
  • Publish an accessibility statement with a way for people to report problems and get help.
  • Build accessibility into design and release checks, so it does not regress.
  • Keep records of testing and fixes.

About overlay widgets

Some products promise instant ADA compliance by adding a script to your site. They cannot fix underlying code problems, many disabled users find them obstructive, and having one has not protected sites from lawsuits. Fix the site itself.

Outside the United States

In the EU, the European Accessibility Act has applied since June 28, 2025 to many consumer products and services, including e-commerce, with obligations based on EN 301 549, which incorporates WCAG 2.1 AA. Other countries have their own laws, many also pointing to WCAG.

What a scan can and cannot tell you

WebAuditOS runs source-based accessibility checks on eligible crawled HTML and browser checks on sampled pages and looks for links that resemble an accessibility statement; it does not read the statement. Those findings are a practical starting list.

It cannot determine ADA compliance or legal risk. Automated checks cover only part of WCAG, and compliance depends on manual testing and on legal facts no scan can see.

Treat any tool that promises ADA compliance with caution, ours included. Tools find problems. People confirm accessibility.

Short answers

Is there an official ADA website standard? For government websites, WCAG 2.1 AA. For businesses, no regulation, but courts usually look to WCAG.

When must government sites comply? April 26, 2027 for larger entities and April 26, 2028 for smaller ones.

Do small businesses need to comply? Businesses open to the public can be sued under Title III regardless of size.

Do accessibility overlays make a site compliant? No.

The checks this maps to

Every check named here runs on every scan, on every plan - what a plan changes is how many pages are crawled, how long the history is kept and what you can do with the result. These are the ids the findings carry, so you can match a line in a report to the explanation above.

Accessibility

What is WCAG, and what does WCAG 2.2 AA require?

WCAG is the international standard for web accessibility. What the levels mean, what WCAG 2.2 AA covers, which laws refer to it, and how to test.

Accessibility

What is web accessibility, and where should you start?

Web accessibility means people with disabilities can use your site. Who it helps, the barriers that block most people, and a practical order to fix them in.
