TLDR
Web accessibility lawsuits hit a new high in 2025: over 5,000 total cases filed across federal and state courts, a 20% increase over 2024. Federal filings alone rebounded 27% to 3,117. E-commerce absorbs 70% of all cases, and 64% of defendants are companies under $25 million in revenue. Settlements run $5,000-$25,000 for small businesses, not counting remediation costs.
- ADA Title III
- The section of the Americans with Disabilities Act that applies to private businesses open to the public. Courts have applied Title III to websites of businesses that offer goods or services to the public, treating those websites as places of public accommodation required to be accessible to people with disabilities.
DEFINITION
- Serial Plaintiff
- An individual who files a high volume of ADA website accessibility lawsuits, often against dozens or hundreds of businesses per year. In 2025, the most active single plaintiff filed 241 lawsuits. Roughly 35 prolific plaintiffs account for about half of all federal web accessibility filings.
DEFINITION
- Demand Letter
- A formal notice sent to a business claiming ADA violations and threatening a lawsuit unless the business negotiates a settlement or remediation plan. Demand letters are more common than lawsuits: an estimated 35,000-50,000 demand letters are sent annually, roughly 7-10 for every lawsuit actually filed.
DEFINITION
- WCAG 2.1 AA
- Web Content Accessibility Guidelines version 2.1 at the Level AA conformance threshold. This covers 50 success criteria (30 at Level A and 20 at Level AA). It is the standard required by the DOJ's 2024 Title II final rule, referenced in virtually every ADA web accessibility settlement agreement, and the practical benchmark courts use to evaluate compliance.
DEFINITION
- Pro Se Plaintiff
- A plaintiff who represents themselves in court without an attorney. Federal pro se ADA Title III lawsuits increased 40% in 2025. Seyfarth Shaw attributes this surge to generative AI tools that help self-represented litigants draft complaints, with tell-tale signs including fabricated case citations and briefs produced faster than humanly possible to type.
DEFINITION
2025 Filing Counts: Three Trackers, Three Methodologies
Before reading any lawsuit number, you need to know where it came from. Three organizations track web accessibility litigation, and they count different things.
Seyfarth Shaw (adatitleiii.com) tracks federal court filings only, distinguishing between website-specific ADA claims and physical-access claims. Their 2025 count: 3,117 federal website accessibility lawsuits.
UsableNet tracks both federal and state courts with a focus on digital accessibility. Their 2025 estimate: approximately 5,100 total lawsuits, a 20% increase over 2024’s 4,187.
EcomBack tracks federal website accessibility cases using broader keyword filtering than Seyfarth. Their 2025 count: 3,948 federal cases, a 23.8% increase from their 2024 count of 3,188.
All three are credible. The differences reflect methodology, not disagreement about the underlying trend. Every tracker shows 2025 as a record or near-record year.
Federal Website Accessibility Lawsuits by Year
The Seyfarth Shaw data goes back to 2017 and is the most-cited longitudinal dataset in the field.
| Year | Federal Web Lawsuits | YoY Change |
|---|---|---|
| 2017 | 814 | - |
| 2018 | 2,258 | +177% |
| 2019 | 2,256 | ~0% |
| 2020 | 2,523 | +12% |
| 2021 | 2,895 | +15% |
| 2022 | 3,255 | +12% |
| 2023 | 2,794 | -14% |

The 2023-2024 decline reflected the impact of stricter standing requirements in the Second Circuit and the Supreme Court’s handling of Acheson Hotels v. Laufer. The 2025 rebound shows the litigation ecosystem adapted: plaintiff firms shifted venue to Illinois and Florida while AI tools enabled a new class of self-represented filers.
Total Digital Accessibility Lawsuits Including State Courts
UsableNet’s broader methodology, which includes state court filings, shows a higher absolute volume and a consistent growth trajectory.
| Year | Total Lawsuits (Fed + State) | YoY Change |
|---|---|---|
| 2020 | 3,503 | - |
| 2021 | 4,011 | +15% |
| 2022 | 4,035 | +1% |
| 2023 | ~4,605 | +14% |
| 2024 | 4,187 | -9% |
| 2025 | ~5,100 | +20% |

State court filings matter because California’s Unruh Civil Rights Act provides $4,000 minimum statutory damages per violation - far exceeding the injunctive-relief-only remedy available under ADA Title III in federal court. California generated just 4 federal website accessibility cases in 2025, but California-based plaintiffs are actively filing in state court instead.
Which Industries Get Sued
E-commerce has dominated this litigation since its inception and continues to. The shift worth tracking is food service’s rapid growth.
Industry Breakdown (UsableNet, 2024 vs. 2025)
| Industry | 2024 Share | 2025 Share |
|---|---|---|
| E-commerce / Retail | 77% | ~70% |
| Food Service | 11% | ~21% |
| Healthcare | 2% | 2-3% |
| Fitness & Wellness | - | 3% |
| Education | 2% | 1% |
| Travel & Hospitality | under 1% | 1% |
| Banking / Financial | under 1% | under 1% |
(UsableNet 2024 Year-End Report; UsableNet 2025 Mid-Year Report.)
EcomBack’s more granular 2025 data shows restaurants, food, and beverages accounted for 1,368 lawsuits (34.65% of all federal filings), while lifestyle, fashion, clothing, and apparel made up 1,025 cases (25.96%). Those two categories alone constituted nearly 60% of all 2025 filings.
The e-commerce concentration correlates directly with platform accessibility rates. Shopify sites averaged 69.6 errors per page in 2025; WooCommerce sites averaged 75.6; Magento sites averaged a worst-in-class 85.4 (WebAIM Million Report, March 2025). 35.8% of the top 500 e-commerce retailers received at least one ADA lawsuit in 2025, up from 30% in 2024 (UsableNet 2025 Year-End Report).
Where Lawsuits Are Filed: Jurisdiction by State
Plaintiff attorneys choose their filing jurisdiction strategically based on standing requirements, available damages, and local judicial interpretations.
Federal Website Accessibility Lawsuits by State (Seyfarth Shaw)
| State | 2023 | 2024 | 2025 | Change (2024-2025) |
|---|---|---|---|---|
| New York | 2,152 | 1,564 | 1,021 | -35% |
| Florida | 385 | 470 | 961 | +104% |
| Illinois | - | 93 | 585 | +529% |
| Minnesota | - | 114 | 162 | +42% |
| Pennsylvania | 143 | 103 | 137 | +33% |
| California | 30 | 3 | 4 | +33% |
(Seyfarth Shaw, adatitleiii.com, April 2025 and March 2026.)
Why Illinois Exploded
Illinois went from 93 federal cases in 2024 to 585 in 2025, a 529% increase. The driver was the Second Circuit’s 2022 ruling in Calcano v. Swarovski, which imposed strict standing requirements that made serial plaintiff claims difficult to sustain in New York. The Seventh Circuit (covering Illinois) does not require a nexus between a website and a physical location, making it significantly more plaintiff-friendly. Florida nearly doubled for the same strategic reasons.
Why California Has Almost No Federal Web Cases
California shows just 3-4 federal website accessibility cases per year, which looks like non-enforcement. The reality: California plaintiff attorneys shifted to state court under the Unruh Civil Rights Act, which provides $4,000 minimum statutory damages per violation plus attorney fees. That damages floor substantially exceeds what’s available under ADA Title III in federal court, where only injunctive relief is available.
Who Files These Cases: Plaintiff Concentration
This is the most counterintuitive feature of web accessibility litigation. A tiny number of people and firms generate most of the lawsuits.
In 2025, 251 individual plaintiffs filed all 3,948 federal website accessibility cases tracked by EcomBack. Just 33 of those plaintiffs accounted for 50.10% of all cases. The most active plaintiff, Michael Sandoval (represented by Manning Law, APC), filed 241 lawsuits - 6.10% of the entire national total by himself.
In 2024, 231 individual plaintiffs filed all 3,188 federal cases. Just 35 prolific plaintiffs filed 50.79% of all cases. The single most active plaintiff in 2024 was Victor Ariza, with 113 lawsuits.
Most Active Plaintiff Law Firms (Federal Filings)
| Law Firm | 2025 Federal Filings |
|---|---|
| Equal Access Law Group, PLLC | 641 (16.24%) |
| Manning Law, APC | 615 (15.58%) |
| Stein Saks, PLLC | Significant volume |
| Gottlieb & Associates | 200+ |
| Mizrahi Kroub LLP | Top 5 |
In 2025, 16 plaintiff firms filed 3,567 lawsuits - 90.35% of all federal website accessibility cases (EcomBack 2025). The top 10 plaintiff firms handled approximately 83% of all digital accessibility lawsuits in 2024 (UsableNet Mid-Year 2024).
AI-Powered Pro Se Filers: A New Category
Federal pro se ADA Title III lawsuits increased 40% in 2025. Self-represented plaintiffs filed 1,867 cases in just the first nine months of 2025, compared to 1,774 in all of 2024 (Seyfarth Shaw, October 2025).
Seyfarth Shaw partner Minh Vu documented the pattern: “Most pro se litigants we encounter are using AI tools to help them litigate.” Tell-tale signs include fabricated case citations, incorrect holdings, and briefs produced faster than humanly possible to type. “These were all-out, scorched-earth litigations. We were getting responses to our filings within an hour,” Vu reported (Bloomberg Law, 2025).
The legal quality of these filings varies widely. But defendants still face defense costs on meritless cases - typically $5,000-$25,000 in attorney fees for a simple dismissal.
Settlement Amounts
Most web accessibility lawsuits settle quietly, making comprehensive data scarce. The available information points to consistent ranges.
Typical settlement range for individual cases: $5,000-$20,000, with an estimated average of approximately $25,000 including attorney fees and remediation commitments (Accessible.org; AllyADA; TestParty). Demand letter resolutions at the pre-litigation stage settle for $1,000-$25,000.
Notable large settlements and penalties:
- Alcazar v. Fashion Nova (N.D. Cal.): $5.15 million class action settlement in 2025 - the largest web accessibility settlement since NFB v. Target ($6 million, 2008). Attorney fees received $2.52 million; California Unruh Act class members were eligible for up to $4,000 each.
- FTC v. accessiBe (January 2025): $1 million FTC penalty for false compliance marketing claims.
- DOJ v. Marriott International (June 2024): $50,000 payment plus accessible reservation system remediation.
Defense costs without paying damages: $5,000-$25,000 for a simple case; $50,000-$100,000+ for complex litigation. One documented example: an electric bike company spent $59,000 ($46,000 in legal fees plus $13,000 in remediation). A CBD company spent over $40,000 in legal fees alone (WSJ, cited by UsableNet).
Total industry cost since 2019: an estimated $370 million in settlements and damages (TestParty). If the 7-10 demand letters per lawsuit estimate holds, the full volume of accessibility legal actions likely exceeds 20,000-50,000 per year.
Repeat Defendants: Being Sued Once Doesn’t End Your Risk
41% of federal cases in 2024 and 46% in 2025 targeted companies that had previously been sued for web accessibility violations (UsableNet Year-End Reports). In 2024, 108 businesses were sued two or more times; two businesses were sued four times.
This happens because settlements often require remediation commitments that businesses fail to fully implement. Serial plaintiff firms track defendants over time and return when new violations appear. The only durable protection is fixing the source code and monitoring for regressions.
The WCAG Standard Courts Use
No court has adopted WCAG 2.2 as a legal standard despite its October 2023 publication. WCAG 2.1 Level AA is the operative standard across all DOJ enforcement, court-ordered remedies, and settlement agreements.
The DOJ’s April 2024 Title II final rule requires WCAG 2.1 AA for state and local government websites (compliance deadline: April 24, 2026 for large entities). All DOJ consent decrees in 2024 specified WCAG 2.1 Level AA. The Alcazar v. Fashion Nova settlement required “substantial conformance with WCAG 2.1.”
For private businesses under ADA Title III, no technical standard is specified by statute. Courts treat WCAG 2.1 AA as persuasive guidance and the de facto benchmark for equitable remedies. Seyfarth Shaw advises businesses to target WCAG 2.1 AA conformance specifically.
What This Data Means for Businesses Evaluating Compliance
The litigation math is straightforward. With 94.8% of websites failing automated WCAG checks (WebAIM Million, 2025), virtually every business without an active accessibility program is exposed. With 5,000+ lawsuits per year and 35,000-50,000 demand letters, the question is not whether you might receive a demand letter - it is when.
The economics favor remediation over settlement. A typical SMB accessibility audit and remediation runs $5,000-$25,000 (TestParty, 2025). A single settlement runs $5,000-$25,000 excluding defense costs. Remediation also eliminates repeat-defendant risk; settlement does not.
A11yProof automates the scanning side: continuous monitoring starting at $29/month catches new violations as they appear, before plaintiff attorneys find them. Automated scanning covers 30-57% of WCAG issues by volume. The remainder requires developer remediation guided by clear violation reports - which is exactly what A11yProof provides.
Q&A
How many web accessibility lawsuits were filed in 2025?
An estimated 5,100 total digital accessibility lawsuits were filed across federal and state courts in 2025, a 20% increase over 2024's 4,187 (UsableNet, 2026). Federal court filings alone rose 27% to 3,117 (Seyfarth Shaw, 2026). EcomBack's independent tracking counted 3,948 federal website accessibility cases in 2025, a 23.8% increase from their 2024 count of 3,188.
Q&A
What industries face the most accessibility lawsuits?
E-commerce and retail absorbs approximately 70% of all web accessibility lawsuits in 2025, down from 77% in 2024 (UsableNet, 2025). Food service grew from 11% to roughly 21% of cases. EcomBack found restaurants, food, and beverages alone accounted for 34.65% of all 2025 federal filings. Healthcare, fitness, and education each represent 1-3% of cases.
Q&A
How much do web accessibility lawsuit settlements cost?
Most web accessibility lawsuits settle for $5,000-$20,000, with an estimated average of $25,000 including attorney fees and remediation (Accessible.org; EcomBack). Demand letters at the pre-litigation stage typically resolve for $1,000-$25,000. Notable exceptions: Fashion Nova settled a class action for $5.15 million in 2025. Defense costs alone run $5,000-$25,000 for simple cases and $50,000-$100,000+ for complex litigation.
Q&A
What percentage of accessibility lawsuits target small businesses?
In 2023, 77% of web accessibility lawsuits targeted companies with under $25 million in revenue. That share shifted to 67% in 2024 and 64% in the first half of 2025, as plaintiff firms gradually moved toward larger targets (UsableNet). Small businesses remain the majority of defendants because they settle faster and with less legal resistance than large companies.
Q&A
Which states have the most accessibility lawsuit filings?
New York leads with 1,021 federal web accessibility lawsuits in 2025, though this is down 35% from 2024. Florida doubled to 961 cases in 2025. Illinois exploded 529% to 585 cases as plaintiff firms migrated there from New York after the Second Circuit's stricter standing rules. California has just 4 federal web accessibility cases in 2025, but California plaintiffs file in state court under the Unruh Civil Rights Act instead (Seyfarth Shaw, 2026).
