ADA compliant website: what the law asks and what compliance means in practice

An ADA compliant website is one that people with disabilities can use as fully as everyone else, and in practice that is measured against WCAG level AA. The Americans with Disabilities Act does not name a technical standard for private businesses' websites, but the Department of Justice, its rule for state and local governments and most court settlements all point to WCAG. This guide is for US business owners and the agencies that build their sites: who the ADA covers online, what the rules say, how big the lawsuit risk is and a practical plan. It is part of our web accessibility guide, which covers the fixes in detail.

Quick answer

• The ADA applies to websites of businesses open to the public, according to the Department of Justice and most courts, although no regulation sets a technical standard for private businesses.
• The yardstick is WCAG AA. Aim for WCAG 2.2 AA, which also meets 2.1 AA, the level the DOJ requires of state and local governments.
• State and local governments have a binding rule: WCAG 2.1 AA by 26 April 2027 (50,000 or more residents) or 26 April 2028 (smaller entities).
• Lawsuits are frequent: Seyfarth Shaw counted 3,117 website accessibility suits in federal court in 2025, plus more in state courts.
• There is no official ADA certification. Compliance is shown by conformance, testing records, an accessibility statement and a way to report problems.
• Overlays don't make a site compliant. Fix the templates.
• Start with the free accessibility checker on one page per template.

Does the ADA apply to websites?

The ADA was passed in 1990, before most businesses had websites, so the text says nothing about them. Three of its titles matter online:

For businesses, Title III is the one that matters. The DOJ's 2022 guidance on web accessibility, still published on ADA.gov, says businesses open to the public must make their websites accessible to people with disabilities, and points to WCAG and the Section 508 standards as helpful guidance. It leaves the choice of method to the business.

Businesses with a shop or office

Courts agree most clearly when the website is connected to a physical location. In Robles v. Domino's Pizza (2019), the Ninth Circuit held that the ADA covered Domino's website and app because they connected customers to the goods and services of its restaurants; ordering a pizza was a service of the physical place. The Supreme Court declined to hear the appeal.

Online-only businesses

Here the federal circuits disagree. Some courts, notably federal courts in New York, have held that a website can be a place of public accommodation on its own. Others require a link to a physical place. The Eleventh Circuit's 2021 ruling for Winn-Dixie, which rejected a website claim, was later vacated as moot, which left the question open there. An online-only business should not assume it is safe: plaintiffs file where the law suits them best, and the states have their own laws.

State laws

Several states add to the federal picture. California's Unruh Civil Rights Act treats an ADA violation as a violation of state law and allows statutory damages of at least $4,000 per violation, which the federal ADA does not; it is one reason many suits are filed in California. New York's state and city human rights laws are also used in website cases.

The rule for state and local governments

In April 2024 the Department of Justice published a Title II rule that, for the first time, sets a technical standard: websites and mobile apps of state and local governments must meet WCAG 2.1 level AA. An interim final rule published on 20 April 2026 moved the compliance dates by one year:

• 26 April 2027 for entities serving a population of 50,000 or more;
• 26 April 2028 for smaller entities and special districts.

The rule has limited exceptions, such as archived content that nobody uses for current business, pre-existing documents and some third-party content. It covers public universities and school districts too. If you build sites for any of these, WCAG 2.1 AA is a contractual floor, and 2.2 AA puts you ahead of the likely next update.

Federal agencies follow a different law, Section 508 of the Rehabilitation Act, whose standards incorporate WCAG 2.0 AA.

Website accessibility lawsuits: how big is the risk?

Website accessibility lawsuits are one of the most common kinds of ADA case. Seyfarth Shaw's ADA Title III tracker counted 3,117 website accessibility lawsuits in federal court in 2025, 27 % more than in 2024 and 36 % of all ADA Title III suits filed in federal court that year. Those figures exclude state-court suits and demand letters settled before any filing, so the real number of claims is higher.

A few patterns stand out:

• Consumer-facing businesses where the site is how customers buy or book (online shops, restaurants, hotels) are typical targets.
• Small businesses are sued, not only large brands, and complaints often list failures that an automated scan finds in seconds.
• Repeat suits happen. A settlement with one plaintiff does not stop another, so fixing the site matters more than settling.
• Remedies under Title III are an injunction to fix the site and the plaintiff's attorney's fees; damages come from state laws such as California's.

The cheapest defence is a site that works: few automated failures, a keyboard-usable checkout, a published accessibility statement and a way for people to report problems.

What "ADA compliant" means in practice

Because no regulation defines it for businesses, an ADA compliant website in practice means four things:

1. It meets WCAG 2.2 level AA, or at least 2.1 AA, on every page and every complete process such as checkout, booking and contact. The WCAG explained guide covers the levels and a checklist.
2. It has been tested by people, not only scanned: a keyboard pass, a screen reader test and a 200 % zoom check on the key journeys.
3. It has an accessibility statement naming the standard, known issues and a contact route. Accessibility statement: what to write has a template.
4. It stays that way. New pages and features are checked before they go live, and problems people report are fixed and answered.

ADA website requirements, translated into fixes

The findings behind most demand letters are the same ones that top every yearly survey of home pages. Each maps to a WCAG AA criterion:

The fixes for each, with code, are in the ten most common accessibility issues.

How to check your website

Start with an automated scan of one page per template: home, a category or listing, a product or service page, the cart and checkout, and the contact form. The checker renders the page in Chromium, runs axe-core with the WCAG 2.2 A and AA rules and names the failing elements:

Automated tests find roughly a third of WCAG issues. They are also the failures complaints most often list, so clearing them is the fastest reduction in risk, but not proof of compliance. Follow the scan with the manual tests in the web accessibility guide, and for a business with real exposure, an audit by an accessibility specialist that covers your key journeys.

A plan to make your website ADA compliant

1. Scan and list. Run the checker on each template and write down every critical and serious finding.
2. Fix templates first. Contrast in the design tokens, labels in the form component, names on the header icons. One fix repairs every page.
3. Walk the money paths by keyboard. Search, add to cart, checkout, booking, contact. Anything you cannot finish without a mouse is a blocker.
4. Test with a screen reader for 20 minutes on the same paths.
5. Publish an accessibility statement with a contact email or phone number, and answer reports within a few working days.
6. Check third parties. Booking widgets, chat, payment and cookie banners are part of your site to a visitor; ask vendors for their conformance report (often a VPAT) and test them yourself.
7. Keep it in the release process. A new page is done when it passes the scan and a keyboard pass.

What about accessibility overlays?

A script that adds an accessibility toolbar does not make a site ADA compliant. It cannot write meaningful alt text or fix a checkout that traps focus, and many screen-reader users find overlays get in the way. In 2025 the Federal Trade Commission ordered one overlay vendor to pay $1 million over claims that its product made websites WCAG-compliant. Businesses using overlays have been sued as well. Spend the budget on fixing the templates.

Questions people ask

Does my website need to be ADA compliant?

If you are a US business open to the public, very likely yes in practice. The ADA names no technical standard for private websites, but the Department of Justice and most courts apply Title III to them, and more than 3,000 website accessibility lawsuits were filed in federal court in 2025. State and local governments must meet WCAG 2.1 AA from April 2027. Aim for WCAG 2.2 AA and ask a lawyer about your case.

Is there an official ADA website certification?

No. No government agency certifies websites as ADA compliant, and badges or certificates sold by vendors carry no legal weight. What you can show is evidence: test results against WCAG 2.2 AA, an audit report, an accessibility statement with a contact route and a record of fixing reported problems. That evidence is what matters if a demand letter arrives.

Which WCAG version does the ADA require?

For private businesses, none by name: the ADA has no technical regulation under Title III, and courts and settlements usually use WCAG 2.1 AA or 2.2 AA. For state and local governments, the 2024 Title II rule requires WCAG 2.1 AA. Building to WCAG 2.2 AA covers both, because 2.2 includes every 2.1 requirement except the retired Parsing criterion.

Can a small business be sued over an inaccessible website?

Yes. The ADA has no size exemption for Title III, and many website accessibility suits are filed against small shops, restaurants and service businesses, often after an automated scan found obvious failures. Under federal law the usual outcome is an order to fix the site plus attorney's fees; some states, such as California, add statutory damages of at least $4,000 per violation.

Does the ADA apply to online-only businesses?

It depends on the court. Some federal courts, notably in New York, treat a website as a place of public accommodation on its own; others require a connection to a physical shop or office, as the Ninth Circuit found in the Domino's case. Because plaintiffs choose where to file and state laws add their own rules, online-only businesses should aim for WCAG AA too.

What should I do if I receive an ADA website demand letter?

Don't ignore it, and don't reply before speaking to a lawyer who handles accessibility cases. Meanwhile, scan the pages the letter names, fix the clear failures such as missing labels, alt text and contrast, and keep dated records of what you tested and changed. A documented plan with a timeline and an accessibility statement helps in any negotiation.
