ADA Website Compliance: Legal Requirements for Business Websites

Website accessibility lawsuits have become one of the most active categories of ADA litigation in the United States. Plaintiffs’ law firms filed thousands of federal ADA website accessibility cases in recent years, targeting businesses ranging from major retailers to local restaurants with simple websites. The legal theory is that a website that is inaccessible to users with disabilities — particularly users who are blind or visually impaired and rely on screen readers — violates Title III of the Americans with Disabilities Act, which prohibits discrimination on the basis of disability in places of public accommodation. For business owners with a web presence, understanding this risk and taking steps to address it is increasingly important.

The Legal Framework

Title III of the ADA prohibits discrimination against individuals with disabilities in the ‘full and equal enjoyment of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation.’ The statute was enacted in 1990, when the internet barely existed. As a result, the ADA does not explicitly mention websites, and the Department of Justice — which enforces Title III — has issued regulations applicable to websites only recently.

In 2024, the Department of Justice published a final rule under Title II of the ADA (which covers state and local government entities) adopting the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA as the applicable accessibility standard for covered entities. The DOJ has indicated its intention to issue similar regulations under Title III for private businesses, and in 2025 issued proposed guidance for Title III website accessibility, though final regulations are still pending as of mid-2026. Critically, courts have not waited for regulations to find Title III liability in website accessibility cases.

How Courts Have Ruled

The circuit courts have split on whether Title III applies to websites. The Eleventh Circuit held in 2021’s Gil v. Winn-Dixie that Title III covers only physical places of public accommodation, and that websites are covered only if there is a sufficient nexus between the website and the physical location. Other circuits, including the First, Second, and Seventh, have taken broader views that websites themselves can be places of public accommodation or at minimum must be accessible to the extent they connect users to physical goods and services.

Regardless of the circuit split on pure legal theory, the volume of settlements reached in website accessibility cases makes it clear that businesses face real financial exposure. The cost of defending even a frivolous ADA website claim — typically a demand letter followed by a lawsuit if settlement is not reached quickly — can easily exceed the cost of making a website accessible in the first place. Serial plaintiffs and their counsel have targeted businesses of all sizes, often sending form demand letters to hundreds of companies.

What WCAG 2.1 Level AA Requires

The Web Content Accessibility Guidelines (WCAG) 2.1 Level AA is the widely accepted accessibility standard for websites and is what most courts and the DOJ look to when evaluating website accessibility. WCAG 2.1 Level AA organizes requirements around four principles: perceivability (information must be presentable in ways users can perceive, including providing text alternatives for non-text content like images, captions for videos, and sufficient color contrast), operability (users must be able to navigate and interact using a keyboard alone, not just a mouse, and content must not include elements that cause seizures), understandability (content must be readable and predictable, with clear error messages on forms), and robustness (content must be compatible with current and future assistive technologies, including screen readers).

Common Website Accessibility Problems

The most frequently cited accessibility failures in ADA litigation include: images without alt text (descriptions that screen readers can convey to visually impaired users), videos without captions or audio descriptions, forms that cannot be completed using a keyboard alone or that have unlabeled fields, menus and navigation that cannot be accessed via keyboard, insufficient color contrast between text and background, and PDF documents that are not screen-reader accessible. Fixing these issues on most websites is not technically complex, but it does require systematic attention.

Practical Steps for Business Owners

The most effective approach to ADA website compliance is to build accessibility in from the start rather than retrofitting it after a demand letter arrives. For businesses with existing websites, a recommended path forward includes conducting an accessibility audit using automated testing tools (such as WAVE, axe, or Google Lighthouse) combined with manual testing, since automated tools catch only 30 to 40 percent of accessibility issues. Prioritize the fixes with the highest impact on users — alt text for images, keyboard navigation, form labels, and video captions. Add an accessibility statement to your website describing your commitment to accessibility and providing contact information for users who experience barriers.

For businesses building new websites or redesigning existing ones, requiring WCAG 2.1 Level AA conformance in the contract with the web developer is the most efficient way to ensure the end product meets the standard. This should be expressed as a specific, auditable requirement, not a general statement that the site should be ‘accessible.’

Responding to Demand Letters

ADA website demand letters typically allege that the recipient’s website is inaccessible in specific technical ways and demand either a settlement payment or immediate remediation (or both). These letters should never be ignored, but they also should not be paid reflexively. Many demand letters are sent by serial litigants and their counsel as a business model. An experienced ADA defense lawyer can help evaluate the strength of the claim, the likely cost of litigation versus settlement, and whether the identified accessibility issues are real and legally actionable in your jurisdiction.

The Bottom Line

ADA website accessibility is a genuine legal obligation in most jurisdictions, not just a best practice or a reputational consideration. The wave of demand letters and litigation in recent years has demonstrated that the cost of inaction — in the form of legal fees, settlements, and remediation under the pressure of litigation — typically exceeds the cost of proactive compliance. Business owners with commercial websites should treat WCAG 2.1 Level AA conformance as a business requirement, not an aspiration.
