The Americans with Disabilities Act (ADA) requires websites to be accessible to people with disabilities. Websites that don't comply face lawsuits, damages, and injunctions. This guide explains legal requirements and penalties.

Jurisdiction

United States

Who must comply

All websites of businesses employing 15+ people; all government agency websites; educational institutions; non-profit organizations receiving federal funding. State-by-state variations apply but federal ADA is nationwide standard.

Penalties

$2,500 per violation – $75,000+ per violation; class action settlements often $1-5 million+

Key Requirements

Comply with WCAG 2.1 Level AA accessibility standards

Websites must meet Web Content Accessibility Guidelines 2.1 Level AA conformance. This includes alt text, keyboard navigation, color contrast, captions, heading structure, and 50+ other criteria.

Penalty: Failure to comply subjects website owner to discrimination lawsuits

Provide equal access to all website features

Users with disabilities must be able to use all functionality. This includes forms, payments, videos, documents, dynamic content. No feature can be inaccessible.

Penalty: ADA Title III violations, damages up to $75,000+ per violation

Make PDFs and documents accessible

Frequently Asked Questions

Who enforces ADA website accessibility?

The Department of Justice (DOJ) can sue for violations. More commonly, disability rights attorneys sue under Title III of the ADA, which allows private lawsuits. Expect plaintiffs' attorneys in every state.

What standard do courts use for ADA website compliance?

Courts consistently reference WCAG 2.1 Level AA as the benchmark. Some cases cite WCAG 2.0 AA, but WCAG 2.1 AA is now the de facto standard in 2026.

Do I need a perfect website or 'good faith effort'?

Courts want substantive compliance, not perfect compliance. But 'good faith effort' requires demonstrable action: audits, remediation, staff training, ongoing testing. Ignoring accessibility = clear violation.

Can I use automated accessibility overlays to comply?

No. Overlays (like accessWidget) are sued separately and don't provide true accessibility. Courts have rejected overlay-only compliance. Use overlays as supplement, not replacement.

What about small businesses or non-profits?

ADA applies. Businesses with 15+ employees must comply. Non-profits receiving federal funding must comply. Small business size is not exemption; digital accessibility is universal standard.
