The Americans with Disabilities Act was signed into law in 1990 — before the web existed. Title III, which covers places of public accommodation, has been applied to websites through decades of court decisions and Department of Justice guidance. Understanding how Title III applies to your website is essential for any business with a public-facing web presence.
Title III of the ADA prohibits discrimination by places of public accommodation on the basis of disability. It requires businesses to ensure that people with disabilities have equal access to goods and services. The 12 categories of public accommodation include restaurants, hotels, retail stores, banks, healthcare providers, and any other business that serves the public — which courts have extended to websites that serve public customers.
Courts have taken different approaches to applying Title III to websites. Some courts apply it only to websites with a nexus to a physical location (the "nexus" theory). Others apply it to any website serving the public regardless of physical presence (the "standalone" theory). The majority of recent federal court decisions have favored finding websites covered by Title III, creating significant compliance expectations for essentially any business with a public-facing website that serves US customers.
The Department of Justice has consistently taken the position that Title III applies to websites. In 2022, the DOJ published guidance confirming that web accessibility is required under the ADA. In 2024, the DOJ published final rules for state and local government websites requiring WCAG 2.1 AA compliance. While the federal rule applies to government entities, it reinforces WCAG 2.1 AA as the applicable standard and signals continued enforcement focus on web accessibility.
Courts have interpreted Title III to require that disabled users have substantially equal access to the same goods and services available to non-disabled users. This means a website that is completely inaccessible to screen reader users fails Title III even if the business has a phone number. It means a checkout process that cannot be completed via keyboard fails Title III even if an alternative purchase method exists. Substantially equal means the online experience itself must be accessible — not that alternative access methods compensate.
Some courts have required plaintiffs to provide businesses with notice of violations before filing suit, giving the business an opportunity to remediate. Other courts have found no notice requirement under Title III. Plaintiff law firms have adapted to notice requirements where they exist by sending demand letters that function as both notice and an opening settlement offer. Proactive compliance eliminates this exposure entirely.
Beyond legal risk, an accessible website expands your potential customer base. Approximately 26% of US adults live with some type of disability. Screen reader users, keyboard-only users, and users with cognitive disabilities represent a significant and often underserved market. Businesses that invest in accessibility often find it improves their experience for all users — better form labels help everyone, sufficient color contrast improves readability for all, and keyboard navigation benefits power users and mobile users.
