Web accessibility compliance in the US comes down to one core question: can every visitor — including people using screen readers, keyboard navigation, or assistive technology — actually use your website? If the answer is no, your business or your clients’ businesses may already be exposed.
This guide covers everything you need to understand in 2026: the laws that apply, the technical standard courts use as their benchmark, the government deadlines that are currently in effect, and the lawsuit trends that make this one of the fastest-growing areas of ADA litigation in the country.
Web accessibility compliance is not a single law with a single checkbox. It is a layered framework made up of federal statutes, court interpretations, and technical guidelines that work together to define what “accessible” means in practice.
The primary legal framework is the Americans with Disabilities Act (ADA). For private businesses, Title III of the ADA prohibits discrimination in places of public accommodation — and courts have consistently ruled that websites qualify. For state and local government entities, Title II of the ADA now includes a formal federal rule with specific technical requirements and compliance deadlines.
The technical standard that threads through all of it is WCAG — the Web Content Accessibility Guidelines published by the W3C. Courts reference WCAG 2.1 Level AA as the de facto benchmark for determining whether a private business website meets ADA obligations. For government entities, WCAG 2.1 Level AA is now the formally mandated standard under the DOJ’s 2024 rule. And for any organization that wants to stay ahead of where standards are heading, WCAG 2.2 AA is the current best practice.
Title III of the ADA applies to businesses operating as places of public accommodation — which courts have repeatedly ruled includes websites, particularly those connected to physical business locations or serving the general public online. There is no specific technical standard written into the statute for private businesses, but WCAG 2.1 Level AA has become the consistent court benchmark. Any private business with a customer-facing website can face a Title III claim.
In April 2024, the Department of Justice published a final rule requiring state and local government entities to bring their websites and mobile apps into conformance with WCAG 2.1 Level AA. Those deadlines were extended in April 2026 by an Interim Final Rule. The current compliance dates are April 26, 2027, for entities serving populations of 50,000 or more, and April 26, 2028, for smaller entities and special district governments.
Federal government agencies and their contractors must comply with Section 508 of the Rehabilitation Act, which also uses WCAG as its technical reference. The Department of Health and Human Services has a parallel rule under Section 504 of the Rehabilitation Act that applies to healthcare and social services organizations receiving federal funding — with a compliance deadline that was extended to May 2027.
WCAG stands for Web Content Accessibility Guidelines. They are published by the World Wide Web Consortium (W3C) and organized around four core principles: content must be Perceivable, Operable, Understandable, and Robust. These principles are broken into guidelines and then into specific, testable success criteria at three levels — A (minimum), AA (standard target), and AAA (enhanced).
WCAG 2.1 Level AA is the current legal baseline — the version courts apply to private business cases and the version the DOJ mandated for government entities. WCAG 2.2, published by W3C in 2023 and approved as an ISO standard in 2025, is the current best practice. It adds nine new success criteria beyond 2.1, including requirements around focus visibility, touch target sizing, drag-free alternatives for pointer interactions, and accessible authentication flows. Because WCAG 2.2 is backward compatible with 2.1, meeting 2.2 automatically means meeting 2.1.
Accessibility litigation is not a future risk. It is a present one — and the numbers from 2025 make that clear.
According to Seyfarth Shaw’s annual tracking, plaintiffs filed 3,117 federal website accessibility lawsuits in 2025 — a 27% increase over 2024 and the second-highest annual total on record. When state court filings are included, total digital accessibility lawsuits for 2025 exceeded 5,000. E-commerce accounted for approximately 70% of all ADA digital accessibility lawsuits that year. Nearly half of all 2025 federal cases targeted companies that had already been sued at least once before.
New York, Florida, and Illinois remain the most targeted jurisdictions. The most common violations cited include missing alt text, low color contrast, unlabeled form fields, and broken keyboard navigation. Notably, nearly half of 2025 cases targeted repeat defendants.

Private businesses are not subject to a specific government-mandated technical standard the way state and local governments are — but that does not mean they are safe. Courts apply WCAG 2.1 AA as their measuring stick. A site that fails basic contrast ratios, skips alt text, or blocks keyboard navigation is a site that is already exposed.
A browser-side accessibility widget gives your site visitors real tools — contrast adjustment, text resizing, screen reader support, dyslexia-friendly fonts, and more — without touching your underlying code. It also demonstrates a proactive commitment to accessibility, which matters when legal exposure becomes a conversation. Explore how AccessPro's accessibility widget for WordPress and Shopify can add this layer in under two minutes.
Widgets alone are not a substitute for proper code-level accessibility work. The most defensible position is a site that combines structural code fixes (proper heading hierarchy, ARIA labels, keyboard navigability, descriptive alt text) with a user-facing accessibility layer and ongoing monitoring.
An accessibility statement published on your site — documenting what standards you are working toward, what tools are in place, and how users can report barriers — is a concrete signal of good-faith effort. Every AccessPro plan includes a WCAG accessibility statement.
