What to Do If You Get an ADA Demand Letter: A Step-by-Step Guide for Small Business Owners

You opened the mail — or worse, your inbox — and there it is: a letter from a law firm claiming your website violates the Americans with Disabilities Act. It references legal statutes, mentions a client with a disability who couldn’t use your site, and often names a dollar figure. Your stomach drops.

First, take a breath. Don’t panic — but don’t ignore it either. These letters are stressful by design, and they are also extremely common. Thousands of small businesses receive one every year. Many of them are resolved without a lawsuit. What you do in the first few days matters, and there is a clear path forward. Many of these letters set a response window — 30 days is common — so acting promptly is important, but acting calmly and correctly matters more than acting fast.

What ADA demand letters actually are

Under Title III of the ADA, businesses that serve the public (“places of public accommodation”) must not discriminate against people with disabilities. Over the last decade, courts in much of the country have extended that principle to business websites — reasoning that if a blind customer can’t use your online booking form or read your menu, they are being denied equal access.

A demand letter is a pre-lawsuit notice. It typically claims that a person with a disability tried to use your website, encountered barriers, and that those barriers violate the ADA (and often a parallel state law). The letter usually asks you to (1) fix your website and (2) pay a settlement and the sender’s legal fees to avoid a formal lawsuit.

It’s worth understanding the ecosystem. A significant share of these letters come from a small number of law firms and repeat plaintiffs — sometimes called “serial filers” — who send letters in volume. That does not mean the underlying accessibility problems on your site aren’t real. In most cases they are. It does mean you are not being singled out, and it means there is a well-worn process for responding.

The four steps to take

1. Contact an attorney

This is the first move, and it is not optional. An attorney who handles ADA website matters can read the specific letter, tell you whether it’s legitimate, explain the deadlines that actually apply to you, and advise on whether and how to respond. Do not call the opposing firm and start negotiating on your own, and do not send an angry reply. Anything you say can shape the settlement conversation. Your attorney will handle that communication.

2. Get an audit to understand what they found

The letter probably lists a handful of alleged violations, but it rarely tells you the full picture. Before you can fix your site — or evaluate any settlement — you need to know what’s actually wrong with it. A manual accessibility audit against WCAG 2.1 AA (the standard these cases almost always cite) gives you a real inventory: which pages fail, which criteria they fail, how severe each issue is, and exactly what a developer needs to change.

This is where a manual audit matters far more than a free scanner. Automated tools catch roughly 30% of issues. The barriers cited in demand letters — a checkout flow you can’t complete with a keyboard, a modal that traps a screen reader, an intake PDF that can’t be read aloud — are usually in the other 70% that only a human tester finds.

3. Begin remediation

Once you know what’s broken, start fixing it. Prioritize the critical, blocking issues first — the ones that stop a disabled user from completing a core task like contacting you, booking, or buying. Hand your developer the audit’s remediation notes so the work is concrete rather than guesswork. Demonstrable progress on real fixes strengthens your position considerably.

4. Document everything

Keep a dated paper trail: when you received the letter, when you retained counsel, when the audit was conducted, what it found, and what you fixed and when. This documentation is the evidence of your good-faith effort. A signed audit letter noting the date the review was conducted, paired with your remediation records, is exactly the kind of contemporaneous record that carries weight if the matter proceeds.

What “good faith effort” means — and why it matters

You will hear the phrase “good-faith effort” a lot. Legally, it refers to taking genuine, documented steps to identify and remove accessibility barriers, rather than ignoring the problem or slapping a useless overlay widget on the site. Courts and opposing counsel treat a business that audited its site and is actively remediating very differently from one that did nothing.

This is the practical reason the documentation in step 4 matters so much. A scanner printout from a free tool shows almost nothing about genuine effort. A dated, manual audit report plus a record of the fixes you made tells a clear story: you took the concern seriously and acted on it. That story can meaningfully affect settlement discussions.

The cost reality

Look at the math honestly. Ignoring the letter, or handling it badly, tends to lead toward a settlement in the $5,000–$25,000 range — plus the sender’s attorney fees, plus your own legal costs, plus the eventual cost of fixing the site anyway. The barriers don’t disappear because you settled; the next plaintiff can send another letter.

Remediating now costs a fraction of that: a $249 manual audit to understand the issues, plus your developer’s time to fix them. You end up with a genuinely more accessible website, a documented good-faith record, and far less exposure going forward. The cheap path and the right path are the same path.

Common questions

Can I just run WAVE and screenshot it? No. Free automated scanners catch a minority of issues and miss the keyboard, screen-reader, and interactive-flow barriers that demand letters actually cite. A scanner printout also does little to demonstrate a genuine good-faith effort. Manual testing is what maps to the real problem.

How long do I have? It varies by letter and jurisdiction — many name a response window such as 30 days, but you shouldn’t wait to find out. Act immediately: contact an attorney and get the audit started so you have real information before any deadline hits.

Does this mean I have to make my site perfect? Perfection isn’t the standard, and chasing it can paralyze you. What matters is a documented good-faith effort: identify the real barriers, prioritize and fix the ones that block access, and keep records of the work. Meaningful, ongoing progress is the goal.
