ADA Website Compliance in 2026: What U.S. Businesses and Governments Need to Know
By Vatsal Shah — Founder & CEO, IAAP WAS-Certified Accessibility Professional
The Americans with Disabilities Act (ADA) of 1990 predates the modern web, but it has become the single most litigated web accessibility law in the world. Two parts matter for websites: Title II (state and local governments) and Title III (businesses open to the public).
Title II: a hard technical standard with hard deadlines
In April 2024, the U.S. Department of Justice published its final rule on web and mobile accessibility under Title II. For the first time, the ADA has an explicit technical standard: WCAG 2.1 Level AA. The rule covers websites, web content, and mobile apps that state and local governments provide or make available — including services delivered through contractors and vendors.
| Compliance deadline | Who |
|---|---|
| April 26, 2027 | Public entities serving 50,000 or more people |
| April 26, 2028 | Public entities serving fewer than 50,000 people, and special district governments |
Those dates are one year later than the original rule. On April 20, 2026 the Department of Justice published an interim final rule (91 Fed. Reg. 20902) extending the April 24, 2026 and April 26, 2027 dates to April 26, 2027 and April 26, 2028. The technical standard did not change: web content and mobile apps must conform to WCAG 2.1 Level AA. Title II’s existing nondiscrimination and effective-communication duties were not paused by the extension. Government vendors should expect WCAG 2.1 AA conformance — usually evidenced by an Accessibility Conformance Report (ACR/VPAT) — to become a condition of doing business with public entities.
Title III: businesses and the lawsuit wave
Title III prohibits discrimination by "places of public accommodation" — retailers, restaurants, hotels, banks, healthcare providers, and virtually any business serving the public. The DOJ has long taken the position that this applies to websites, and courts have overwhelmingly allowed web accessibility suits to proceed. The practical result:
- Thousands of federal ADA website lawsuits are filed every year (plus state-court filings under laws like New York's and California's Unruh Act);
- E-commerce sites are the most common target, and serial plaintiffs routinely test sites with screen readers;
- Demand letters and settlements typically cost tens of thousands of dollars — before you pay to fix the site anyway;
- Sites relying on accessibility overlay widgets have themselves been sued; overlays do not deliver WCAG conformance.
While Title III has no codified technical standard, courts and settlements consistently use WCAG 2.0/2.1 AA as the benchmark. With the Title II rule cementing WCAG 2.1 AA as the ADA's reference standard, that is the level every U.S.-facing website should target. For the mid-2026 filing counts — by revenue, industry, platform, and state — see ADA website lawsuits in the USA: who is being sued and why.
Canadian and international businesses are not exempt
ADA lawsuits regularly name non-U.S. companies whose websites serve U.S. customers. If Americans can buy from your site, an ADA demand letter can reach you — a common surprise for Canadian e-commerce brands. (Canadian businesses should also review their domestic obligations under the Accessible Canada Act and provincial laws such as Ontario's AODA and Manitoba's AMA.)
Practical steps
- Audit against WCAG 2.1 AA with manual assistive-technology testing — the issues plaintiffs cite (missing alt text, unlabeled forms, keyboard traps, inaccessible menus and checkout) are exactly what manual testing finds, and they are often invisible to automated scans;
- Remediate at the source instead of installing an overlay;
- Publish an accessibility statement with a working feedback channel — it deters suits and demonstrates good faith;
- Government entities and their vendors: treat April 26, 2027 and April 26, 2028 as the Title II technical deadlines and get ACR/VPAT documentation in order;
- Retest after every major release — accessibility regressions are the top reason sites get sued twice.
