ADA Website Compliance: How to Avoid an Accessibility Lawsuit

Under the Americans with Disabilities Act, businesses open to the public are expected to make their websites usable for people with disabilities, and website accessibility lawsuits and demand letters keep coming, often aimed at small businesses. The practical fix is real accessibility work against the WCAG guidelines, not a plugin. Here's what I tell clients. (This isn't legal advice. If you get a letter, talk to an attorney.)

Why does website accessibility matter?

Lawsuits get the attention, but the real point is that your site should work for everyone, including:

• People with visual impairments and people using screen readers
• People with mobility limitations who navigate by keyboard
• Neurodivergent users
• Anyone who just needs clear structure and easy navigation

An accessible site is also a better site: easier to use, clearer to search engines and AI tools, and more credible.

What standard should a website meet?

The Web Content Accessibility Guidelines (WCAG), Level AA. WCAG 2.1 AA is the version most often cited in legal settings. WCAG 2.2 AA is the current version, and it's what we build to. WCAG is organized around four ideas:

• Perceivable. Alt text, enough color contrast, captions, readable type.
• Operable. Everything works with a keyboard, with visible focus and predictable behavior.
• Understandable. Clear headings, labels, form instructions and error messages.
• Robust. Clean code that screen readers and other assistive tech can interpret.

Most problems come from simple things: missing alt text, low-contrast text, broken keyboard navigation, videos without captions, inaccessible PDFs, and fancy animations that get in the way.

Can my business get sued over its website?

Yes. ADA Title III covers "places of public accommodation," and courts have increasingly treated business websites as part of that, especially when they're tied to a physical location. Thousands of website accessibility suits are filed every year, and small businesses are frequent targets because settling often looks cheaper than fighting.

This isn't theoretical for me. The R&D Dept. has been on the receiving end of predatory legal firms too. And a lot of these letters come from the same handful of firms, whose own sites often aren't compliant.

How do I spot a predatory ADA demand letter?

Some complaints are legitimate. Many aren't. Red flags:

• "Pay now or be sued immediately" language
• A claimant who has never done business with you
• Boilerplate text that's clearly been sent to hundreds of businesses
• No actual test results showing what's broken
• A push to buy a monthly "compliance plugin"

Don't ignore it and don't panic. Get an attorney involved, ask for specifics, and document a real remediation plan and the progress you're making.

What does real accessibility compliance look like?

Three layers:

• Technical. Semantic HTML, a proper heading order, keyboard support, correct ARIA labels, accessible forms and good contrast.
• Content. Alt text, descriptive link text, captions and transcripts, accessible PDFs.
• Ongoing practice. Regular audits with automated scans plus manual testing, accessibility built into every update, and training for whoever edits the site.

There's no one-click fix. Accessibility overlays don't make a site compliant on their own, and they've shown up in lawsuits themselves.

How does The R&D Dept. help?

We run real audits (automated scans plus hands-on keyboard and screen reader checks), fix the issues in the site itself, and document what was done so you have a paper trail. We hold our own site to WCAG 2.2 AA too.

Quick answers

Does the ADA apply to websites?

For many businesses, yes. Courts have increasingly applied ADA Title III to websites of businesses open to the public, so it's smart to treat accessibility as a requirement.

What WCAG level should my website meet?

Level AA. WCAG 2.1 AA is the most commonly referenced; WCAG 2.2 AA is the current version and a safe target.

Do accessibility overlay plugins make a site compliant?

No. Overlays can't fix underlying code and content problems, and sites using them still get sued.
