For private businesses in the US, ADA website compliance comes down to one legal reality: Title III of the Americans with Disabilities Act applies to your website, and courts have been ruling on that basis for years. There is no single checklist that grants immunity — but there is a clear technical standard that courts use to evaluate whether a site meets its obligations, and a growing body of case law that shows what happens when it does not.
Title III of the ADA prohibits discrimination in places of public accommodation. The statute was signed in 1990 — before ecommerce existed — but federal courts have consistently interpreted it to include websites, particularly those connected to physical business locations or serving the general public online.
No specific technical standard for private business websites is written into the ADA statute itself. What courts have done, in case after case, is apply the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA as the de facto benchmark for determining whether a site meets ADA obligations. If your site fails the criteria in WCAG 2.1 AA, a plaintiff’s attorney has a ready framework to argue that it fails ADA requirements.
The Department of Justice has reinforced this position through enforcement actions, consent decrees, and statements of interest in private litigation — even as it has not yet published a specific Title III rulemaking for private businesses. WCAG 2.1 AA is not law for private businesses. But it is the closest thing to a measurable standard that courts consistently apply.
The violations that appear most often in demand letters and complaints are not obscure edge cases.
They are basic, testable failures that automated scanning tools can identify in minutes.
Color contrast is the single most common issue — it affects approximately 79% of home pages according to WebAIM's 2025 Million analysis. Body text must meet a minimum contrast ratio of 4.5:1 against its background. This catches brands with light gray text, low-contrast buttons, and text layered over images.
Missing image alt text appeared on approximately 55% of home pages in the same analysis. Screen readers cannot interpret an image without alt text — they either read the filename or skip the element entirely. For a blind user, that means lost context and an incomplete experience.
Inaccessible forms — fields without proper labels, forms that cannot be completed by keyboard alone — are another common anchor for claims.
Common accessibility issues include broken heading structures, missing ARIA labels on interactive elements, and checkout or purchase flows that block disabled users from completing transactions.
E-commerce and retail businesses are the most frequently targeted. According to UsableNet’s 2025 tracking, ecommerce accounted for approximately 70% of all ADA digital accessibility lawsuits that year. Food service was the second most targeted industry. Healthcare and hospitality are growing targets as plaintiff firms expand their scope.
Size is not a reliable shield. The majority of defendants in 2025 federal cases were companies with annual revenue under $25 million. Small and mid-sized businesses are targeted as frequently as large national brands — and they are often less prepared to defend claims.
Online-only businesses are not automatically protected either. Courts in several jurisdictions, including New York federal courts, have found that websites without any physical location can still qualify as places of public accommodation.
01
Start with a WCAG 2.1 AA scan. Free and low-cost automated tools — including WAVE and Axe — can identify the most common failures quickly. Automated tools catch approximately 30-40% of accessibility issues, so manual review of your site’s navigation, forms, and checkout flow is also important.
02
Add a user-facing accessibility layer. A browser-side accessibility widget gives visitors tools to adjust contrast, font size, spacing, and more without altering your site’s code. When combined with code-level fixes, it demonstrates active, documented effort — which courts and plaintiffs weigh differently than a site that has taken no steps at all.
03
Publish an accessibility statement. It documents what you are working toward, what tools are in place, and how users can report barriers they encounter. It is a concrete signal of good-faith effort.
Address the most common failures first. Color contrast, alt text, form labels, and keyboard navigation cover the majority of violations cited in 2025 complaints. Fixing those reduces exposure faster than any other starting point.
