Partial dataset: 2021 through Q1 2026 · approx. half the total tracked caseload · full dataset publishing later in 2026

8,392 federal cases — roughly half the full picture. The complete dataset, covering all tracked ADA web accessibility litigation, will be published later in 2026. For years, ADA web accessibility litigation was treated as a niche legal concern. The data tells a very different story.

Based on analysis of 8,392 federal court cases filed between 2021 and Q1 2026 — an extract representing approximately half of the total tracked caseload, with the full dataset to be published later this year, what began as a trickle of lawsuits has become a systematic, industrialised wave of litigation that is accelerating, repeating, and targeting entire industries at scale. The numbers alone frame the magnitude.

In 2021, 466 ADA web accessibility cases were filed in federal court. From there, the growth has never stopped.

What is most significant about this trajectory is that it has been consistent and compounding. There is no single event — no court ruling, no legislative change, no enforcement surge — that explains any individual year's increase. The litigation has been driven by a structural condition: millions of commercial websites that remain inaccessible to blind, low-vision, and mobility-impaired users, combined with a specialised plaintiff bar that has built systematic operations to identify and pursue those failures at scale.

Who gets sued — and why fashion and retail dominate

The single largest target industry in this dataset is Apparel & Fashion, with 1,153 defendant companies. Retail follows with 796, then Hospitality with 640. Consumer Goods (460), Food & Beverages (360), Restaurants (323), and Cosmetics (264) round out the top categories.

The pattern is not coincidental. These industries share a structural profile that makes them both high-traffic targets and common sources of accessibility failures. Apparel and retail sites are typically rich with product imagery — photography that requires descriptive alt text for screen readers. Checkout flows require keyboard navigability and properly labelled form fields. Video content needs captions. All of these are implementation details that get deprioritised in fast-moving digital commerce environments, particularly at companies managing dozens of product categories and seasonal refreshes.

Hospitality and food service face the same pressures, with the added complication that many restaurant and hotel websites are built on third-party platforms — reservation systems, menu tools, booking engines — where the operator may not even control the underlying accessibility compliance. Being a customer of a non-compliant platform does not insulate a business from being named as defendant.

The repeat defendant problem — can you be sued more than once?

Yes — and with a frequency that surprises most companies who have already been through the process once. Of the defendant companies tracked in this partial dataset, 776 have been named in more than one case. More significant: 570 have faced lawsuits in more than one different calendar year, meaning the settlement they reached in 2022 provided no lasting protection from a new filing in 2023, 2024, or 2025.

The companies sued every year from 2022 through 2026 include some of the most recognisable names in consumer commerce: Urban Outfitters, Prada USA, Amazon, Five Below, and Tapestry among them. TJX Companies — parent to T.J. Maxx, Marshalls, and HomeGoods — has accumulated 17 separate cases. Marriott International has been named across five different legal entities for a combined 30 cases.

The structural reason for this repetition is important to understand. Each lawsuit is typically filed by a different individual plaintiff, often represented by the same law firm that brought an earlier action, targeting a specific set of pages or a specific accessibility failure. Settling one case — even with a commitment to remediate — creates no legal bar against a new plaintiff filing against the same company for a different issue on the same website, or for the same issue if the remediation was incomplete. The legal mechanism does not provide protection; only genuinely fixed code does.

The multi-brand multiplier

For companies operating multiple consumer brands under a single corporate umbrella, the litigation risk does not simply add up — it multiplies. Tapestry owns Coach, Kate Spade, and Stuart Weitzman, each with its own ecommerce website. Winning or settling a case against Kate Spade's website provides no protection for Coach's. Each domain is a separate legal exposure. Each site's accessibility failures — or the absence of them — stands independently under the law.

The same logic applies to any conglomerate, franchise, or multi-brand retailer. A company operating five brands online has five times the surface area for accessibility lawsuits. If those brands share a technology platform, a single shared accessibility failure could result in five simultaneous or sequential complaints. If they operate independently, the failure of one to remediate after a settlement creates continued exposure for the group as a whole.

The data bears this out. Among the most-sued defendants, many appear under multiple distinct legal entity names — TJX Companies alongside individual brand-level entities; Marriott International appearing five different ways. These are not duplicate entries. Each represents a separately filed lawsuit, often in a different federal court, targeting a slightly different version of the same underlying problem.

The plaintiff bar — a concentrated, industrial operation

What makes this litigation wave different from typical consumer protection enforcement is its source. Across the cases in this dataset, the overwhelming majority are not driven by individual disabled consumers encountering accessibility barriers in their daily lives. They are manufactured at scale by a small number of specialised plaintiff law firms that have built systematic operations around identifying accessibility failures and filing complaints in volume.

Just three firm groups — Gottlieb & Associates / Jeffrey M. Gottlieb, Stein Saks PLLC, and the Pelayo Duran / Roderick V. Hannah practices — account for 44% of all cases filed. The top ten firms handle 67.6%. The top twenty handle 92% of the entire dataset. Of 654 plaintiff law firms that appear in these records, more than half appear in only a handful of cases — the tail is long, but the head is extremely concentrated.

These firms do not wait for clients with grievances to walk through the door. The business model is scanning-and-filing: websites are audited programmatically for accessibility violations, lists of targets are assembled, and complaints are filed in batches. The economics work at volume — settlements that are individually modest become a sustainable practice at industrial scale.

What this means for businesses

The data from eight-plus years of ADA web accessibility litigation converges on several practical conclusions. First, the risk is not diminishing. The growth curve has been consistent and is accelerating, not plateauing. New plaintiff firms are entering the market as established ones mature, ensuring that the pressure will not ease as any individual operation slows down.

Second, settlement is not resolution. A company that settles without genuinely remediating its website has only purchased time before the next filing. The cases in this dataset are full of defendants who appear in 2022, settle, and reappear in 2024 with a new case from a different plaintiff. The legal process provides no immunity; only the technical fix does.

Third, the multi-brand and multi-site reality requires enterprise-level thinking. A company that manages accessibility at the individual brand or property level will always be exposed somewhere. The only durable approach is a consistent accessibility standard applied across every digital property, maintained through ongoing monitoring rather than one-time remediation.

For industries with the highest defendant concentrations — apparel, retail, hospitality, consumer goods — the data makes clear that ADA web accessibility is not a peripheral compliance matter. It is an active, ongoing legal risk that is already materialising in court for hundreds of companies in those sectors, and it will continue to do so until the underlying technical failures are removed.
