ADA Website Compliance Checker: Find the Barriers Behind ADA Risk

AccessibilityScore.in scans a public web page for the WCAG failures that most often come up in ADA website accessibility complaints, and explains each one in plain language. This guide covers what the ADA expects from websites, which deadlines apply, and where an automated check fits.

Last reviewed by the HalfAccessible accessibility team

Short Answer

An ADA website compliance checker scans pages for accessibility barriers, measured against WCAG, that can keep people with disabilities from using a site. The ADA covers websites of state and local governments (Title II) and businesses open to the public (Title III). A scan helps find and fix problems, but it cannot certify ADA compliance.

Key facts

Who the ADA covers online
State and local governments (Title II) and businesses open to the public (Title III)
Technical standard for Title II
WCAG 2.1 Level AA, under the DOJ rule published 24 April 2024
Title II deadline, 50,000+ population
26 April 2027 (extended by a DOJ interim final rule on 20 April 2026)
Title II deadline, smaller entities
26 April 2028, also for special district governments
Technical standard for Title III
None in the regulation; DOJ points businesses to WCAG and the Section 508 Standards
What a checker proves
That specific barriers exist; never that a site is ADA compliant

Does the ADA apply to websites?

Yes. The US Department of Justice states that the ADA applies to the web content of state and local governments under Title II and of businesses open to the public under Title III. Both must make the programs, services and goods they offer online accessible to people with disabilities, including people who are blind, deaf, or who cannot use a mouse.

For state and local governments, a 2024 DOJ rule makes the requirement specific: web content and mobile apps generally must meet WCAG 2.1 Level AA, with limited exceptions such as archived content and some pre-existing documents. For businesses, the Title III regulations name no technical standard, so courts, settlements and DOJ guidance use WCAG as the practical benchmark.

What are the ADA Title II website deadlines?

The DOJ's Title II rule was published on 24 April 2024. On 20 April 2026 the Department published an interim final rule that moved the compliance dates back by one year:

  • State and local governments serving a population of 50,000 or more: 26 April 2027.
  • Those serving fewer than 50,000 people, and all special district governments: 26 April 2028.
  • Third-party content and apps a government uses for its services, such as payment or booking tools, are covered too.

What does an ADA website checker look for?

There is no official ADA test, so an ADA checker tests against WCAG, the standard the DOJ references. AccessibilityScore.in runs axe-core and its own rules on the rendered page and reports barriers that commonly block people from completing tasks:

  • Images and icon buttons without text alternatives, which screen reader users cannot identify
  • Form fields without labels, which make checkout, booking and contact forms unusable non-visually
  • Text with too little colour contrast for people with low vision
  • Missing focus indicators and tiny tap targets that make keyboard and touch use difficult
  • Invalid ARIA that misreports controls to assistive technology
  • Missing page titles and language, which affect navigation and pronunciation

Can a scan make your website ADA compliant?

No. ADA compliance is about whether people with disabilities can actually use the site, which depends on meaning, behaviour and whole tasks that a tool cannot judge. A clean automated scan is evidence that common code-level barriers are absent, not proof that the site is accessible.

The same applies to overlay widgets that add a toolbar or claim to fix a site automatically. They do not change the underlying code that screen readers and keyboards rely on, and no tool, overlay or certificate can make a site ADA compliant on its own.

How should you reduce ADA website risk?

Treat accessibility as ongoing quality work, with evidence:

  • Scan your key templates and fix critical and serious findings first.
  • Manually test your most important tasks with a keyboard and a screen reader.
  • Publish an accessibility statement with a working way to report problems, and respond to reports.
  • Keep records of audits, fixes and re-tests; they show good-faith effort.
  • Check third-party widgets, PDFs and video, which are common sources of barriers.
  • Get a manual WCAG 2.2 AA audit, and legal advice, before making compliance claims.

Common Questions

Is there an official ADA website compliance test?

No. The DOJ does not certify websites or endorse tools. WCAG is the technical standard it references, and WCAG 2.1 AA is required for state and local governments under Title II.

Which WCAG level does the ADA require?

For Title II entities, WCAG 2.1 Level AA. For businesses under Title III, no level is written into the regulation, but WCAG 2.1 or 2.2 Level AA is the common benchmark in settlements and audits.

When do state and local government websites have to comply?

After the April 2026 extension: 26 April 2027 for entities serving 50,000 or more people, and 26 April 2028 for smaller entities and special district governments. Check ada.gov for any later changes.

Does the ADA apply to small business websites?

Title III applies to businesses open to the public regardless of size, and the DOJ says their online goods and services must be accessible. How that applies to a specific business is a legal question for a lawyer.

Will an accessibility overlay protect me from an ADA lawsuit?

An overlay does not fix the underlying code that assistive technology uses, so the barriers that lead to complaints can remain. Fixing them in the source code is the reliable path.

Is this ADA checker free?

Yes, for a single public HTTPS page. Whole-site scans use page scan credits, at $10 for 1,000 pages.

Is this legal advice?

No. This guide explains the ADA and WCAG in general terms. For decisions about your organisation's obligations, talk to a lawyer who works on disability access.
