ADA Title II and WCAG 2.1 AA: A Guide for US Government Websites

ADA Title II and WCAG 2.1 AA: Complete Government Compliance Guide

The U.S. Department of Justice's final rule under ADA Title II represents a significant shift in digital accessibility requirements for state and local government websites. This comprehensive guide will explain what the rule requires, who it affects, key deadlines, and practical steps for government agencies to achieve compliance.

Understanding ADA Title II

What Is ADA Title II?

The Americans with Disabilities Act (ADA) Title II prohibits discrimination on the basis of disability in programs, activities, and services of public entities (state and local governments). The DOJ's 2024 final rule specifically addresses web and mobile application accessibility.

The 2024 Final Rule Overview

Key Requirements:

• State and local government websites must meet WCAG 2.1 Level AA
• Mobile applications must meet WCAG 2.1 Level AA
• Requirements apply to web content and mobile apps used for public services
• Specific deadlines based on population size

Historical Context: For years, WCAG compliance was de facto required through litigation and settlements. The 2024 rule makes it explicit and provides clear technical standards and enforcement mechanisms.

Who Is Covered by the Rule?

Covered Entities

State Governments:

• State agency websites
• State service portals
• State department applications
• State higher education institutions

Local Governments:

• City and county websites
• Municipal service portals
• Local government applications
• Public school district websites

Special Districts:

Population-Based Deadlines

Large Entities (Population 50,000+):

• Compliance Deadline: April 24, 2026
• Examples: Major cities, large counties, state agencies
• More resources and time for implementation

Small Entities (Population under 50,000):

• Compliance Deadline: April 24, 2027
• Examples: Small towns, rural counties, special districts
• Additional year for compliance

Special Districts:

• Generally follow small entity timeline
• Deadlines may vary based on specific circumstances
• Must assess individual requirements

What WCAG 2.1 Level AA Means

The Four Principles

WCAG 2.1 is organized around four principles that provide the foundation for web accessibility:

1. Perceivable Information and user interface components must be presentable to users in ways they can perceive.

Key Requirements:
