Where accessibility lawsuits are filed – and why it matters

Where accessibility lawsuits are filed – and why it matters An anatomy of 8,788 cases, 1,380 plaintiffs, and the handful of districts where America's ADA web docket actually lives.

If you sell anything to the U.S. public through a website, your legal exposure is not distributed evenly. It clusters — by federal circuit, by zip code, by the law firm of a few dozen prolific filers. We compiled and analyzed every accessibility case we could find on PACER and read 81,509 individual issue allegations to map exactly where the docket lives, who is in it, and how the geography of these filings shapes the rules every other business has to plan for.

The growth curve no business plan modeled for

Federal accessibility filings used to be a niche. As recently as 2019 we count six new cases in the entire calendar year; in 2020, despite COVID-driven traffic shifts to digital channels, the number was still under fifty. The inflection point is sharp and recent: 466 in 2021, 755 in 2022, 1,018 in 2023, 2,156 in 2024, and 3,449 in 2025. The first four months of 2026 already show 878 new filings — pacing toward a year roughly comparable to 2025, but with growth no longer compounding the way it did in the four years prior.

Two structural shifts explain most of that curve. The first is the arrival of standalone website-accessibility theory in the Second Circuit (NY) and the First Circuit (MA) in the late 2010s, which decoupled an ADA Title III claim from any need to tie a website back to a brick-and-mortar location. That doctrinal shift opened the door for plaintiffs to sue purely-online retailers, and it made New York the most efficient venue in the country for these cases.

The second is the maturing of a specialized plaintiffs' bar — a small set of firms with templated complaints, paid testers, and operational pipelines that can file dozens of new actions per week. As we'll see, those firms are not distributed evenly across the country, and the courts where they sit have effectively become the ADA web-accessibility courts whether or not Congress, the DOJ, or the Supreme Court ever intended that result.

“The geography of these cases is not a story about where defendants do business. It is a story about where plaintiffs' counsel keep their offices.”— Editorial summary of dataset findings

The map: A litigation belt running from Manhattan to Miami

Accessibility filings are far from uniformly distributed. Using the area codes attached to plaintiff counsel as a venue proxy, four states — New York, Florida, Minnesota, and California — account for the substantial majority of all U.S. accessibility filings, with Pennsylvania, Illinois, and a handful of others rounding out the long tail. New York alone is the home base for plaintiff counsel in roughly 36% of the cases where state could be inferred.

Three districts dominate. The Southern and Eastern Districts of New York (Manhattan, Brooklyn, Queens, Long Island, Staten Island) are the structural center of gravity. The Southern and Middle Districts of Florida (Miami, Fort Lauderdale, Tampa, Orlando) are a near-second, with their own established plaintiffs' bar. And the District of Minnesota has emerged in the past four years as a third hotspot, almost entirely on the back of a single Twin Cities-area firm filing high volumes of cases against out-of-state defendants.

What you do not see clustered at the top of this map is just as informative. Texas, despite a huge consumer economy, accounts for a tiny share of filings — in part because its federal courts have been less hospitable to standalone website ADA claims. California ranks fourth in our federal proxy, but that figure dramatically understates its real exposure: most California accessibility actions are filed in state court under the Unruh Civil Rights Act, which provides statutory damages that the ADA itself does not. Those state-court filings do not appear in our PACER-derived dataset at all.

Why the venue matters: Three circuits, three doctrines

The reason the docket clusters where it does is not random. Federal circuit courts have arrived at meaningfully different positions on what the Americans with Disabilities Act actually requires of a website, and those doctrinal differences make some courthouses materially more attractive to plaintiffs than others. The most consequential split is between circuits that recognize a standalone theory (a website is itself a place of public accommodation) and circuits that require a nexus to a physical location before Title III applies.

Two practical implications follow. First, a national e-commerce business has roughly the same level of actual compliance obligation in every state — the WCAG 2.1 AA conformance level remains the de-facto reference standard the courts and the DOJ both gravitate toward — but the litigation risk is concentrated in a handful of districts. Second, a defendant with no operations in New York can still be sued in S.D.N.Y. if its website transacts with New York consumers, which is part of why these courts have become national venues.

Who is filing: the prolific 100

If geography is the first lens, plaintiff identity is the second. A small group of named plaintiffs — testers who file repeatedly through the same firm — is responsible for a remarkable share of the entire docket. In our dataset of 1,380 unique plaintiffs, the top ten alone account for nearly 15% of all plaintiff slots, and the top hundred for approximately 57%. The pattern is the rule, not the exception.

Repeat-tester filings are not, on their own, illegitimate. The ADA contemplates private enforcement, and a person who genuinely cannot use websites because of a disability has no obligation to be a one-time complainant. But the volume and clustering — the same names filing dozens or hundreds of nearly-identical complaints in the same district through the same firm — is what shapes the practical posture of these cases. Defendants with operations in S.D.N.Y., S.D. Fla., D. Minn., or W.D. Pa. should expect that the plaintiff pleading is a templated complaint with minimal individualized investigation, and that an early settlement offer will be the fastest path off the docket.

The bar: A small, professional ecosystem on both sides

The plaintiffs' bar in U.S. accessibility litigation is not large. We count 582 distinct plaintiff law firms in the dataset, but the meaningful concentration is much tighter than that. Just ten plaintiff firms generate over half of all representations, and the top twenty-five generate just under three-quarters. On the defense side the picture is different in shape but similar in concentration: a handful of large national labor-and-employment shops, with deep ADA Title III practices, do the bulk of the work, often defending the same brands repeatedly across multiple jurisdictions.

What this concentration means in operational terms: counsel on both sides see the same complaints, the same fact patterns, the same settlement parameters every week. Plaintiff firms typically operate on a contingency model with carefully calibrated demand letters; defense firms have institutional playbooks for early disposition. The result is a market that more closely resembles a regulatory clearance process than a truly contested litigation market — which is also why the median time-to-closure is so short.

The pace: Most cases close before they ever look like cases

The single most useful metric for understanding what these lawsuits actually are is the time from filing to closure. Across 6,951 closed cases in the dataset for which we have both dates, the median is just 97 days. Nearly half close within ninety days; over four-fifths close within six months. Almost none survive past two years. This is not the timing pattern of contested civil litigation — it is the timing pattern of a market that runs on early settlement.

The implication for any defendant is that the operational question — how quickly your in-house and outside counsel can stand up a settlement and remediation plan — usually matters more than the doctrinal one. A motion-to-dismiss strategy in S.D.N.Y. that delivers a substantive order eighteen months after filing rarely produces a different economic outcome than an early negotiated settlement at thirty days. It only changes the cost of the path.

What is actually being sued over

The category mix of issues alleged across these complaints is, in itself, a compact map of where modern web design fails disabled users. Across 81,509 issue allegations, the dominant categories are not exotic. They are the same screen-reader, keyboard, image, and form failures that any conformance audit against WCAG 2.1 AA would surface within an afternoon.

What is striking is how little of the docket is about edge cases. The single largest specific category — about a fifth of all issues we could classify — is screen-reader announcement failures: buttons that announce as “button,” status changes that aren't announced at all, ARIA-live regions that never update. That is also the category most directly addressable through manual remediation work, and the category most consistently flagged by tools like NVDA and JAWS in conformance testing. The legal risk and the engineering work converge on the same surface area.

What this geography means for your business

Risk in this docket is not uniform across companies. A pure-online retailer headquartered in Texas with no operations east of the Mississippi has a meaningfully different exposure profile than a multi-state hospitality chain or a bank with branches in five states. The calculator below produces a directional risk score using the same factors that, in practice, drive whether a templated complaint shows up in a company's mailroom this quarter or not.
