WCAG 2.1 Level AA: The Legal Standard Explained
TL;DR
WCAG 2.1 Level AA is the internationally recognized standard for web accessibility. Courts use it as the benchmark for ADA compliance. It's 50 specific success criteria your site must meet.
What This Violation Means
The Web Content Accessibility Guidelines (WCAG) 2.1 are technical standards published by the World Wide Web Consortium (W3C), the main international standards organization for the web. WCAG has three conformance levels: A (minimum), AA (mid-range), and AAA (highest). Level AA is the standard that courts, government agencies, and the U.S. Department of Justice reference for digital accessibility compliance. It includes 50 success criteria organized under four principles: Perceivable, Operable, Understandable, and Robust.
Why Demand Letters Cite This Violation
- It's the internationally recognized, consensus-based accessibility standard
- U.S. Department of Justice explicitly recommends WCAG 2.1 Level AA in guidance documents
- Federal courts have consistently referenced it in ADA website lawsuits since 2017
- Provides clear, testable technical requirements (not vague 'make it accessible' language)
- Developed through multi-year process with input from accessibility experts worldwide
- Maintained by W3C, a neutral standards organization
- Used by governments globally (EU, Canada, Australia all reference WCAG)
Real-World Example from Actual Demand Letters
A typical demand letter states: "The website fails to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA, the internationally recognized standard for digital accessibility and the benchmark recommended by the U.S. Department of Justice for ADA compliance. Specific violations include..." (followed by a list of specific WCAG success criteria violations). Legal settlements consistently require websites to conform to WCAG 2.1 Level AA and maintain that conformance for 2-3 years under court monitoring.
What the Law Says
- The Department of Justice has stated in multiple guidance documents that "websites should conform to WCAG 2.1 Level AA"
- In 2024, DOJ published a Final Rule requiring Title II entities (state and local governments) to conform to WCAG 2.1 Level AA
- Title III (private businesses) still has no specific regulation, but:
- Federal courts have consistently cited WCAG 2.1 Level AA as the standard
- Settlement agreements uniformly require WCAG 2.1 Level AA conformance
- Department of Justice uses WCAG 2.1 Level AA in its enforcement actions
Practical reality: WCAG 2.1 Level AA is the de facto legal standard for website accessibility in the United States.

DIY Approach
2. Test your site against each of the 50 success criteria
3. Use automated tools (WAVE, axe DevTools) to catch obvious issues
4. Perform manual testing for issues automated tools can't detect:
- Screen reader compatibility
- Keyboard navigation
- Focus management
- Logical reading order
5. Document all failures with screenshots and descriptions
6. Implement fixes following WCAG techniques documentation
7. Re-test to verify fixes work
8. Create ongoing testing process for new content
Realistic timeline: 40-80 hours for someone learning accessibility for the first time on a medium-complexity site. Most businesses hire professionals.

Our Experience Fixing This Violation
We've performed WCAG 2.1 Level AA audits on hundreds of websites ranging from small attorney sites to enterprise e-commerce platforms processing millions in annual revenue. The challenge is that WCAG conformance requires both automated scanning AND expert manual testing - automated tools catch maybe 30-40% of issues, the rest requires human judgment. For Ashley Furniture's site, we conducted a comprehensive audit of their e-commerce platform, product pages, checkout flow, and account management system, documenting over 200 violations across all 50 WCAG success criteria. We then systematically remediated each issue, implementing accessible component patterns that could be reused across their platform. For attorney websites, we typically find 30-50 violations on initial audit, most of which can be fixed in 10-20 hours. The key to successful WCAG compliance is treating it as an ongoing process, not a one-time fix - every time new content is added or design changes are made, accessibility must be maintained.
