California Supreme Court: Unruh Act Requires WCAG 2.1 AA for All Business Websites
The California Supreme Court issued a landmark ruling in September 2025, holding that the Unruh Civil Rights Act — California's primary anti-discrimination law — requires all business websites serving California residents to meet WCAG 2.1 AA standards. This decision is significant because the Unruh Act provides for statutory damages of $4,000 per violation, plus attorney's fees, creating massive financial exposure for non-compliant websites.
The Ruling in Detail
The court held that: (1) a business website is a 'place of public accommodation' under the Unruh Act, consistent with federal ADA interpretation; (2) WCAG 2.1 AA is the applicable technical standard for determining whether a website is accessible; (3) statutory damages of $4,000 are available per visit by a disabled person who encounters an accessibility barrier — not per unique violation type, creating potential for significant cumulative damages; (4) the defendant's 'we were planning to fix it' argument was rejected — accessibility must be maintained proactively.
Why This Matters Beyond California
California is the world's 5th largest economy and home to a disproportionate share of tech companies, e-commerce businesses, and startups. The Unruh Act applies to any business with customers in California — not just businesses headquartered there. Because statutory damages are relatively easy to prove (compared to actual damages under federal ADA), this ruling creates a powerful incentive for plaintiffs' firms to file in California state courts.
Color Contrast Implications
The ruling explicitly referenced color contrast as an example of a measurable, objective accessibility criterion. A website with text at 3.5:1 contrast (below the 4.5:1 WCAG AA threshold) creates a 'barrier' under the Unruh Act for every disabled person who encounters that text. For high-traffic pages, statutory damages could accumulate rapidly. This makes color contrast auditing one of the highest-ROI legal risk mitigation activities for any business with California customers.
Action Items for Businesses
If you have customers in California: (1) audit your full site for WCAG 2.1 AA compliance within 30 days; (2) prioritize color contrast — it's the cheapest fix with the highest litigation exposure; (3) document your remediation process — showing active, good-faith compliance efforts can reduce damages; (4) consider publishing an accessibility statement with contact information for reporting issues, which may help resolve complaints before they become lawsuits.
The California ruling is expected to influence courts in other states and may accelerate federal legislation establishing clear web accessibility standards under the ADA.
