Americans with Disabilities Act

Overview

The Americans with Disabilities Act (ADA) is a landmark US civil rights law enacted in 1990, with major provisions effective in 1992. It prohibits discrimination against individuals with disabilities across employment, public services, public accommodations, and telecommunications. Although it predates the modern web, US courts and the Department of Justice have increasingly interpreted it to require that websites, mobile apps, and other digital services be accessible.

For software teams, the ADA is the central reason web accessibility is a legal obligation in the United States, even though the statute itself does not name specific technical standards. Courts commonly look to the Web Content Accessibility Guidelines (WCAG) as the de facto benchmark.

Who It Applies To

Title I covers employers with fifteen or more employees. Title II covers state and local government entities and their programs and services. Title III covers private businesses considered public accommodations, such as retailers, banks, restaurants, healthcare providers, and many online services. Web and mobile properties of these entities are frequently treated as covered. A 2024 DOJ rule under Title II adopted WCAG 2.1 Level AA as the technical standard for state and local government web and mobile content.

Key Requirements

Covered entities must not discriminate on the basis of disability and must provide equal access to goods, services, and information. For digital services this generally means conforming to recognized accessibility standards, providing auxiliary aids such as captions and alternative text, ensuring keyboard operability and screen-reader compatibility, and offering reasonable accommodations. Employers must provide reasonable accommodations for qualified employees and applicants.

Penalties for Non-Compliance

The ADA is enforced through DOJ action and private lawsuits. Remedies include injunctive relief requiring remediation, attorneys' fees, and, in DOJ enforcement, civil penalties. Title III private suits typically seek injunctive relief and fees rather than damages. Web accessibility lawsuits and demand letters have grown substantially.

How to Comply

Adopt WCAG 2.1 or 2.2 Level AA as an internal standard, integrate automated and manual accessibility testing into development, and remediate existing barriers. Provide accessible alternatives, maintain an accessibility statement and feedback channel, and train designers and developers. Treat accessibility as an ongoing practice rather than a one-time audit.
