From WCAG 2.1 to the ADA and Section 508: the rules for an internet accessible to all.
Three regulatory pillars define digital accessibility in the United States today. With our in-house tools and human auditors, we help you comply with all of them.
WCAG 2.1 (Web Content Accessibility Guidelines) are part of a set of international recommendations developed by the Web Accessibility Initiative (WAI) within the World Wide Web Consortium (W3C). These guidelines define the technical criteria for making web content accessible to everyone, including people with disabilities.
The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities. Title II covers state and local governments, while Title III applies to businesses open to the public — and courts have consistently applied it to websites. In 2024, the Department of Justice issued a final rule setting WCAG 2.1 AA as the technical standard for Title II web content and mobile apps, a benchmark that also guides Title III compliance and drives a growing wave of lawsuits and demand letters.
Section 508 of the Rehabilitation Act requires federal agencies — and the vendors that sell to them — to make their information and communication technology accessible, using WCAG as the reference standard. On top of federal law, state statutes such as California’s Unruh Civil Rights Act attach monetary damages to violations, fueling thousands of web accessibility lawsuits and demand letters every year.
Each country adopts its own standards, almost always based on WCAG: here is the international regulatory landscape.
