How many ADA web accessibility lawsuits are actually filed?
There's no single official count — several firms track court dockets differently, and their numbers reflect that. Seyfarth Shaw's ADA Title III blog, which tracks federal filings specifically over website and app accessibility, counted 3,117 such lawsuits in 2025, up 27% from 2,452 in 2024. Zoom out to all federal ADA Title III filings (physical locations included, not just digital), and website cases now make up 36% of that total, up from 28% a year earlier — accessibility litigation is claiming a growing share of ADA enforcement generally.
Count state courts too, and the totals rise. UsableNet's 2025 year-end report — which tracks federal and state digital accessibility filings together — tallied 4,928 lawsuits for the year. EcomBack, which runs its own e-commerce-focused tracker, counted 3,948 lawsuits in 2025, up 23.8% from 3,188 in 2024. Different scopes, same direction: every major tracker shows filings rising year over year, not falling.

E-commerce is still the top target — but its share is easing
E-commerce sites accounted for 69% of all digital accessibility lawsuits in 2025, according to UsableNet's year-end report — still comfortably the largest single category, though down from roughly 77% the year before. UsableNet's 2024 report also found that among the top 500 e-commerce retailers, 35.8% had received at least one ADA accessibility lawsuit. The declining e-commerce share doesn't mean online retail is safer; it means litigation is spreading into healthcare, financial services and hospitality as plaintiffs' firms broaden their targets.
Repeat targeting is the other side of that story. UsableNet counted 1,427 companies hit with a repeat ADA web-accessibility claim in 2025 — meaning they'd already been sued once before over the same category of issue. A prior lawsuit, or even a settlement, doesn't inoculate a site against being sued again if the underlying barriers were never actually fixed.
If you're currently running an overlay or accessibility widget and reading this as a warning sign, it's worth understanding what a non-overlay alternative actually changes versus what a widget changes.
Top states: New York still leads, but Illinois is surging
New York, Florida, California and Illinois account for the large majority of ADA website lawsuits, per EcomBack's 2025 annual report. New York's raw filing count actually fell year over year while Florida, California and especially Illinois grew sharply — a sign that plaintiffs' firms are actively diversifying where they file, not just filing more in the same three states.

The stats point to one fix: know your real issues before someone else finds them
None of these numbers tell you whether your own site is a target — but the overlay stat is the one worth sitting with. Nearly a quarter of sued sites in 2025 already had a widget installed, which means the widget wasn't checked against the site's actual markup before the lawsuit landed. A real WCAG scan shows you the same category of issue a plaintiff's firm would find, with the specific success criterion and a fix you can apply to your own code.

Start by working through a straightforward list of common fixes rather than layering another script on top of the problem. It won't guarantee you're never sued — no vendor, including us, can honestly promise that — but a documented, good-faith remediation effort is a materially different position than an unfixed site wearing a toolbar.
Frequently asked questions
How many ADA website accessibility lawsuits are filed each year?
In 2025, Seyfarth Shaw's ADA Title III tracker counted 3,117 federal lawsuits specifically over website and app accessibility, up 27% from 2,452 in 2024. Broader trackers that also include state courts count higher: UsableNet's 2025 year-end report tallied 4,928 digital accessibility lawsuits, and EcomBack's annual report counted 3,948 using its own methodology. The exact total varies by tracker and court scope, but every major report shows year-over-year growth.
What percentage of ADA lawsuits target e-commerce websites?
E-commerce sites accounted for 69% of digital accessibility lawsuits in 2025, according to UsableNet's year-end report — still the largest single target, though down from roughly 77% in 2024 as plaintiffs' firms expanded into healthcare, financial services and hospitality sites.
Do accessibility overlays or widgets prevent lawsuits?
Not reliably. EcomBack's 2025 annual report found that 24.9% of sued sites (983 of 3,948) already had an overlay or widget installed when they were sued, up from 22.65% in 2024. Its mid-year 2025 report put the first-half figure at 22.6%. Changing the visitor-facing toolbar doesn't change the underlying markup that a lawsuit, or a screen reader, actually encounters.
Which states have the most ADA website lawsuits?
New York, Florida, California and Illinois lead. EcomBack's 2025 annual report recorded 1,108 New York filings, 950 in Florida, 787 in California and 576 in Illinois — Illinois' count grew from just 92 in 2024, one of the sharpest state-level jumps in the data.
What should I do if I've received an ADA demand letter?
Don't rely on an overlay as your response. Get the immediate steps from a dedicated demand-letter guide, then run a real scan of your site so you know exactly which WCAG issues exist and can show a documented, good-faith effort to fix them. This isn't legal advice — talk to an attorney about your specific letter.
