United States

The United States has the most fragmented accessibility-law landscape of any major economy — and the only one where private litigation, not a national regulator, is the dominant enforcement engine. The Americans with Disabilities Act of 1990 (ADA) and the Rehabilitation Act of 1973 set the federal floor across employment, government services, public accommodations, federally-funded programmes, and federal procurement. Sector-specific statutes — the CVAA for communications, the Air Carrier Access Act for aviation, Section 255 for telecommunications equipment — layer on top. State laws like California's Unruh Civil Rights Act and New York's NYSHRL / NYCHRL add statutory-damages multipliers that turn a single inaccessible checkout flow into a class-action exposure measured in millions. The federal ADA itself provides only injunctive relief plus attorneys' fees in private Title III actions, but it is the fee-shifting mechanism at 42 U.S.C. § 12205 that has driven over four thousand federal web-accessibility filings per year through the mid-2020s.

The constitutional and treaty floor

The United States Constitution contains no clause specific to disability discrimination. The Equal Protection Clause of the Fourteenth Amendment has been interpreted to reach disability-based state action, but only under rational-basis review — the most deferential tier of constitutional scrutiny — following City of Cleburne v. Cleburne Living Center, Inc., 473 U.S. 432 (1985). That means the practical floor for federal disability rights in the United States is statutory, not constitutional. Congress's authority to enact the ADA against private actors rests on the Commerce Clause; against state and local government, on Section 5 of the Fourteenth Amendment as construed in Tennessee v. Lane, 541 U.S. 509 (2004) and constrained by Board of Trustees of the University of Alabama v. Garrett, 531 U.S. 356 (2001).

On the international-treaty side, the United States signed the UN Convention on the Rights of Persons with Disabilities (CRPD) on 30 July 2009 but has not ratified it. The Senate's December 2012 ratification vote fell five votes short of the two-thirds supermajority required, and the treaty has not been brought back to the floor in any of the Congresses since. The United States is therefore not a State Party to the CRPD and is not subject to the Committee on the Rights of Persons with Disabilities' periodic review cycle. The CRPD has limited interpretive weight in US courts; the operative legal framework is purely domestic statutory law. That distinguishes the US from every other OECD economy of comparable size — all of which have ratified the convention and submit periodic reports to the Committee.

The federal landscape: ADA + Rehabilitation Act

The federal accessibility floor sits on two pillars: the Americans with Disabilities Act of 1990 and the Rehabilitation Act of 1973. Together they cover employment, state and local government, public accommodations, federally-funded programmes, and federal procurement — with different agencies, different remedies, and different private-right-of-action availability for each.

ADA Title I (42 U.S.C. § 12111 et seq.) prohibits employment discrimination on the basis of disability by employers with 15 or more employees, requires reasonable accommodations absent undue hardship, and is enforced by the Equal Employment Opportunity Commission (EEOC) through 29 CFR Part 1630. A private plaintiff must first file a charge with the EEOC and obtain a right-to-sue letter; civil-damages caps under 42 U.S.C. § 1981a range from $50,000 to $300,000 per claimant depending on employer size.

ADA Title II (42 U.S.C. § 12131 et seq.) prohibits discrimination by state and local government entities — every agency, department, courthouse, transit system, public school district, public university, and special-purpose authority. The Department of Justice enforces Title II under 28 CFR Part 35 and may refer cases to the United States Attorneys for federal-court litigation. Private plaintiffs may sue directly under 42 U.S.C. § 12133. The April 8, 2024 DOJ final rule amending 28 CFR Part 35 (89 Fed. Reg. 31320) for the first time imposes a specific technical conformance standard on state and local government web content and mobile applications: WCAG 2.1 Level AA. The compliance deadlines are staged by entity size — public entities with 50,000 or more population (and special-purpose districts of comparable size) must comply by 24 April 2026; smaller entities by 26 April 2027.

ADA Title III (42 U.S.C. § 12181 et seq.) is the most litigated provision of US accessibility law. It prohibits disability discrimination by places of public accommodation — restaurants, hotels, retail stores, theatres, doctors' offices, gyms, banks, and the full list of twelve enumerated categories at 42 U.S.C. § 12181(7). The Department of Justice enforces Title III under 28 CFR Part 36, and private plaintiffs may sue under 42 U.S.C. § 12188 for injunctive relief and reasonable attorneys' fees, expert fees, and costs under 42 U.S.C. § 12205. There are no compensatory or punitive damages available under federal ADA Title III — the fee-shifting provision is the entire economic engine of private Title III litigation, supplemented (in California and a few other states) by state-law statutory damages that piggyback on the federal ADA claim.

The most contested doctrinal question in Title III law is whether websites are themselves "places of public accommodation." The federal circuits are split. The First, Second, and Seventh Circuits hold that a website can be a place of public accommodation in its own right, regardless of whether it has any physical-store connection (Carparts Distribution Center, Inc. v. Automotive Wholesaler's Ass'n of New England, Inc., 37 F.3d 12 (1st Cir. 1994); Doe v. Mutual of Omaha Insurance Co., 179 F.3d 557 (7th Cir. 1999)). The Third, Sixth, Ninth, and Eleventh Circuits require a "nexus" between the inaccessible website and a physical place of public accommodation (Robles v. Domino's Pizza, LLC, 913 F.3d 898 (9th Cir. 2019); Gil v. Winn-Dixie Stores, Inc., 993 F.3d 1266 (11th Cir. 2021)). The Supreme Court has repeatedly declined to take up the question, most prominently in October 2019 when it denied certiorari in Domino's Pizza, LLC v. Robles, 140 S. Ct. 122 (2019). Forum-shopping into circuits with the broader rule is a routine plaintiff-side strategy.

The Rehabilitation Act of 1973 (29 U.S.C. § 791 et seq.) covers the federal sector and federal-funding recipients along three tracks. Section 501 covers federal employment. Section 504 covers any programme or activity receiving federal financial assistance — hospitals taking Medicare or Medicaid, universities taking federal student aid, transit agencies taking FTA grants, and the entire constellation of federally-funded non-profit and state actors. Section 504 imports the Title II standard for state/local recipients and the Title III standard for private recipients. Section 508 (29 U.S.C. § 794d) imposes accessibility obligations on the federal government's own information and communications technology procurement; the 2017 Section 508 Refresh, codified at 36 CFR Part 1194 by the US Access Board, harmonised the federal procurement standard with WCAG 2.0 Level AA and the EU's EN 301 549 standard.

Sector-specific federal statutes

Sitting alongside the ADA-Rehabilitation Act backbone are three sector-specific federal statutes that pull entire industries out of the general framework and into a dedicated regulatory regime.

The 21st Century Communications and Video Accessibility Act of 2010 (CVAA), Pub. L. 111-260, amended the Communications Act of 1934 to extend accessibility obligations to advanced communications services (interconnected and non-interconnected VoIP, electronic messaging, interoperable video conferencing), video programming delivered via IP, equipment used for advanced communications services, and the user interfaces of digital apparatus that displays video programming. The Federal Communications Commission implements the CVAA through 47 CFR Parts 6, 7, 14, 79, and related provisions, and issues forfeiture orders for non-compliance. CVAA-implementing rules also impose closed-captioning quality requirements, video-description obligations on the top broadcast and cable networks, and accessibility requirements for emergency information.

The Air Carrier Access Act of 1986, 49 U.S.C. § 41705, prohibits disability discrimination by US and foreign air carriers operating to, from, or within the United States. The Department of Transportation enforces the ACAA through 14 CFR Part 382. Subpart C of Part 382 — substantially amended in 2013 and again in 2024 — imposes specific obligations on carrier websites, mobile applications, automated kiosks at US airports, and in-flight entertainment systems. Major carriers have entered DOT consent orders with civil-penalty components: United Airlines paid $2 million in 2016 for ACAA violations including wheelchair-handling and website accessibility; Delta Air Lines paid $750,000 in 2011 for inaccessible website and kiosk violations; American Airlines was hit with a $50 million civil penalty in 2025 for systematic wheelchair-handling failures including web-disclosure deficiencies, the largest ACAA penalty in DOT history.

Section 255 of the Communications Act of 1934, 47 U.S.C. § 255, requires manufacturers of telecommunications equipment and providers of telecommunications services to make their offerings accessible to and usable by individuals with disabilities, where readily achievable. The FCC enforces Section 255 through 47 CFR Part 6. Section 255 predates the CVAA and overlaps with it in some respects; the FCC has issued interpretive guidance reconciling the two on questions like advanced communications services and IP-based services.

The state-law multiplier

State accessibility statutes are where the US framework departs most dramatically from every other major economy's. State laws are not preempted by the federal ADA — the ADA expressly preserves stricter state and local laws at 42 U.S.C. § 12201(b). A handful of states have used that authority to enact statutory-damages provisions that turn the federal ADA's injunctive-relief-only regime into a financial-damages regime through state-law piggyback claims.

California — Unruh Civil Rights Act (Cal. Civ. Code § 51) is the most consequential. Unruh prohibits discrimination by "all business establishments of every kind whatsoever" in California; it incorporates ADA violations by reference (Munson v. Del Taco, Inc., 46 Cal. 4th 661 (2009)), and Cal. Civ. Code § 52(a) provides statutory damages of $4,000 per access denial plus attorneys' fees and costs. Multiple discrete access denials on the same visit can be pleaded as multiple violations. The California Disabled Persons Act (Cal. Civ. Code § 54.3) provides minimum statutory damages of $1,000 per violation on a parallel theory. California enacted reforms in 2012 (SB 1186) and 2015 (AB 1521) to curb construction-defect serial litigation, but those reforms do not meaningfully restrict web-accessibility plaintiffs, who continue to file in California state court at high volume.

New York runs two parallel state-and-city statutes. The New York State Human Rights Law (Exec. Law § 296) and the New York City Human Rights Law (NYC Admin. Code § 8-101 et seq.) both prohibit disability discrimination in public accommodations. The NYCHRL is the more aggressive of the two: it is construed liberally in favour of plaintiffs by command of the NYC Council (NYC Admin. Code § 8-130), permits punitive damages, and applies a lower causation standard than federal law. Typical NYCHRL awards in adjudicated accessibility cases fall in the $5,000–$50,000 range per claimant, with attorneys' fees on top. Southern and Eastern District of New York federal-court filings on website accessibility have consistently led the country since 2018.

Other significant state regimes: the Illinois Human Rights Act (775 ILCS 5) provides damages of $1,000–$10,000 plus attorneys' fees; Massachusetts's public-accommodations statute (M.G.L. c. 272 §§ 92A, 98) provides statutory damages and attorneys' fees; the New Jersey Law Against Discrimination (N.J.S.A. 10:5-1 et seq.) provides uncapped compensatory and punitive damages; Texas Human Resources Code § 121, Florida § 760, and Ohio R.C. § 4112 round out the major state regimes that plaintiffs piggyback onto federal ADA claims.

The result is the "serial-plaintiff" phenomenon: a small number of plaintiff-side firms file very large volumes of nearly identical complaints, particularly in California, New York, Florida, and (more recently) Illinois. The filings target small and mid-market businesses with web presences but limited compliance budgets, and resolve quickly through settlements that combine a remediation roadmap with an attorneys'-fee payment in the $5,000–$25,000 range per case. Federal-court filings on web accessibility have hovered around 4,000–5,000 per year through 2023 and 2024 by industry trackers, with the long-running California-state-court Unruh docket adding several thousand more.

Technical standards and conformance

The US has no single technical accessibility standard the way the EU has EN 301 549. Different statutes reference different technical regimes, and the precise version of WCAG that applies varies by sector and by year.

Section 508's 2017 Refresh codifies WCAG 2.0 Level AA at 36 CFR § 1194.1 et seq. for federal-government information and communications technology procurement. The Refresh harmonised the federal procurement standard with the EU's EN 301 549, simplifying compliance for vendors selling in both markets. The DOJ April 2024 final rule under Title II imposes WCAG 2.1 Level AA on state and local government web content and mobile applications, on the staged 2026/2027 timeline. The DOJ has not yet (as of mid-2026) issued the long-anticipated Title III rulemaking that would set a technical standard for private-sector public accommodations; the absence of a federal regulation is what drives the circuit-split jurisprudence and the related "what does compliance mean?" practical uncertainty.

Sector-specific technical regimes layer on: the FCC has issued implementing rules on closed-captioning quality (47 CFR § 79.1) and video description (47 CFR § 79.3); DOT's 14 CFR Part 382 Subpart C requires WCAG 2.0 AA conformance on US-air-carrier websites; the Department of Education's OCR enforces accessibility against universities and K-12 schools by reference to WCAG 2.0 / 2.1 AA. The professional-certification ecosystem — the International Association of Accessibility Professionals' Certified Professional in Accessibility Core Competencies (CPACC) and Web Accessibility Specialist (WAS) credentials — provides a labour-market signal of technical conformance capability but no legal safe harbour.

Penalties — the full exposure stack

The five-layer exposure stack in the US is more spread out across enforcement actors than in any EU member state, and the dominant layer is layer 3 — private state-law statutory damages and attorneys' fees — rather than the federal administrative-penalty layer. All figures below are in US dollars (USD) and reflect the 2023 inflation adjustments to federal civil-monetary-penalty caps under the Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015.

The federal-administrative layer is, in absolute terms, modest by EU standards — the FCC's $112,536 per-violation cap is roughly comparable to Germany's BFSG €100,000 per-incident cap. What makes the US exposure stack singular is layer 3, the state-law statutory-damages route, and the volume at which it is exercised. A single California Unruh case targeting an inaccessible checkout flow can plead five or ten discrete access denials, generating a damages claim of $20,000–$40,000 plus attorneys' fees, all on a federal-ADA-violation predicate that costs the defendant essentially nothing in compensatory damages under federal law alone.

The attorneys'-fee award at 42 U.S.C. § 12205 (and its state-law counterparts) is the load-bearing economic mechanism. Federal courts have held repeatedly that fee awards in successful ADA cases must be "reasonable" but may exceed the damages recovered by orders of magnitude. The Ninth Circuit's decision in Vargas v. Howell, 949 F.3d 1188 (9th Cir. 2020) and the Eleventh Circuit's decision in Norelus v. Denny's, Inc., 628 F.3d 1270 (11th Cir. 2010) frame the analytical structure; in practice, fee awards in resolved Title III matters cluster in the $5,000–$25,000 range per case at settlement and can reach six figures in litigated matters.

Major published settlements over the last decade illustrate the upper end. Target Corporation settled the NFB v. Target class action in 2008 for $6 million plus injunctive relief — the first major web-accessibility class settlement. H&R Block paid approximately $100,000 plus comprehensive website-remediation commitments in its 2014 DOJ consent decree. Hilton Worldwide paid $50,000 plus extensive web-and-reservations-system remediation in its 2010 DOJ consent decree. American Airlines paid $50 million in 2025 in the DOT's largest-ever ACAA settlement, on a fact pattern combining wheelchair-handling failures with web-disclosure deficiencies. Domino's Pizza, after the Ninth Circuit ruling against it on the nexus question in 2019, settled its underlying case for an undisclosed amount in 2021.

Enforcement record and outlook

Federal DOJ enforcement under ADA Titles II and III has been steady but selective through the 2020s — the agency picks pattern-or-practice cases and high-visibility consent decrees rather than chasing individual websites. The Disability Rights Section's caseload combines proactive compliance reviews, complaint-driven investigations, and friend-of-court briefs in significant private litigation. The April 2024 Title II web-accessibility final rule represents the largest substantive expansion of DOJ accessibility regulation since the 2010 ADA Standards for Accessible Design and the most consequential federal accessibility-regulatory action of the current decade.

FCC CVAA enforcement has been steady — the agency issues forfeiture orders against carriers and equipment manufacturers for advanced-communications-services accessibility failures, video-description shortfalls, and closed-captioning quality issues. DOT ACAA enforcement intensified sharply through 2024 and 2025 under the Office of Aviation Consumer Protection, with the American Airlines $50 million civil-penalty order standing as the watershed action. State attorney-general enforcement has been most active in California (where the AG's office regularly intervenes in Unruh enforcement) and New York (where the New York AG's Civil Rights Bureau pursues NYSHRL accessibility cases against major retailers, banks, and entertainment venues).

The private-litigation engine continues at the volumes described above: industry trackers logged roughly 4,000–5,000 federal ADA web-accessibility filings per year through 2023 and 2024, concentrated in SDNY, EDNY, the Central District of California, and the Southern District of Florida, with a long tail of cases in every other federal district. The Robles v. Domino's Pizza and Gil v. Winn-Dixie decisions remain the load-bearing circuit-court precedents; the Supreme Court has continued to decline opportunities to resolve the underlying circuit split.

What's coming in 2026–27

Three concrete developments dominate the 2026–27 calendar. First, the DOJ Title II web-accessibility rule's compliance dates: 24 April 2026 for large state and local government entities (50,000 population or larger), and 26 April 2027 for smaller entities. The first round of post-deadline DOJ enforcement and private Title II litigation under the new standard will start moving through the federal courts in mid-to-late 2026. Second, the long-anticipated DOJ Title III rulemaking on private-sector web accessibility — promised since the 2010 Advance Notice of Proposed Rulemaking and not yet issued — remains on the regulatory agenda; whether it surfaces in 2026 depends on administration priorities. Third, the US Access Board has signalled a Section 508 Refresh-2 to track WCAG 2.2 once the underlying technical standards mature, and the FCC's CVAA implementation continues to expand into 5G and IP-based services. The circuit split on whether websites are "places of public accommodation" remains ripe for Supreme Court review but unresolved.
