Most businesses find out they have an accessibility problem the same way. A demand letter shows up, and suddenly "we didn't know" becomes the most expensive sentence they've ever said.
Here's the reality: ADA website accessibility lawsuits bounced back hard in 2025. According to Seyfarth Shaw's annual report, 3,117 federal court filings were recorded — a 27% increase from 2024. When state court filings are included, UsableNet's 2025 Year-End Report puts the total at 5,114 cases. The theory that accessibility litigation was slowing down turned out to be wrong.
And it's not just large corporations getting targeted. 77% of ADA lawsuits target companies with under $25 million in revenue. If you have a website, you have exposure.
What Does a Demand Letter Actually Look Like?
Most accessibility cases don't start in a courtroom. They start with a demand letter — typically from a plaintiff's attorney alleging that your website violated Title III of the Americans with Disabilities Act by being inaccessible to users with disabilities. The letter usually demands remediation and a financial settlement to avoid litigation.
Settlements typically range from $5,000 to $75,000, and that's before attorney fees, redesign costs, and any ongoing monitoring requirements the settlement includes. The total cost of an unresolved complaint can easily reach six figures once you factor in emergency remediation done under legal pressure.
What makes this particularly frustrating is that nearly half of all cases in 2024 were filed against companies that had already been sued before. Getting sued once and patching the most obvious issues isn't enough. Courts and plaintiffs' attorneys are looking for full compliance, not spot fixes.
What Standard Are You Being Held To?
This is where a lot of businesses get caught off guard. The ADA itself doesn't specify a technical web standard. But courts, the DOJ, and federal agencies have consistently applied WCAG 2.1 Level AA as the benchmark in Title III cases. If your website doesn't meet that standard, you're exposed — regardless of whether you knew the standard existed.
WCAG 2.1 Level AA covers things like color contrast ratios, keyboard navigation, screen reader compatibility, form labels, and alt text for images. These aren't obscure requirements. They're the baseline. And the majority of websites on the internet fail them.
The Three Violations That Trigger the Most Complaints
Based on litigation patterns and the most recent WebAIM Million Report data, these are the violations that show up most often in demand letters:
Missing alt text on images — screen reader users can't interpret unlabeled images, and linked images without alt text are completely non-functional for navigation.
Inaccessible forms — unlabeled form fields mean a user relying on a screen reader can't tell what information goes where. Your contact form, your booking form, your checkout — all potential liability.
Keyboard inaccessibility — if a user can't navigate your site without a mouse, you're blocking an entire category of users with motor disabilities. This is one of the most common and most actionable failures.
What "We Didn't Know" Actually Costs
The financial exposure is real, but the less-discussed cost is time. A demand letter typically gives you 30 days to respond. Emergency remediation under that kind of deadline is expensive, rushed, and often incomplete — which means you're at risk of a follow-up complaint.
The businesses that fare best are the ones who find the problems before a plaintiff's attorney does. A proactive audit costs a fraction of a settlement, takes weeks instead of days, and gives you a remediation roadmap you can actually execute thoughtfully.
What To Do Right Now
You don't need a full audit to start reducing your exposure today. Here's where to begin:
Run your homepage through WAVE (wave.webaim.org) — it's free and will flag the most obvious violations in under a minute.
Check your contact form — tab through it using only your keyboard. If you get stuck, a screen reader user is getting stuck too.
Look at your images — do they have descriptive alt text? Do your linked images describe where the link goes?
These three checks won't make your site fully compliant, but they'll tell you quickly whether you have a problem worth addressing before someone else finds it for you.
The Bottom Line
ADA website accessibility litigation isn't slowing down. 5,114 lawsuits in 2025. A 27% increase year over year in federal filings alone. Settlements that routinely exceed the cost of remediation several times over. And nearly half of defendants had already been sued once before.
The lawsuit you never saw coming is the one you could have prevented with an audit.
