The Complete Guide to ADA Compliance and WCAG 2.2 for US Commercial Websites

Under Title III of the Americans with Disabilities Act (ADA), commercial websites are legally recognized as places of public accommodation. Ensuring compliance with WCAG 2.2 AA standards protects your business from legal exposure while expanding your accessible market reach.

Core WCAG 2.2 AA Accessibility Requirements

• Perceivable: Text alternatives (alt text) for all informative images, proper color contrast ratios (≥ 4.5:1 for normal text), and clear visual focus indicators.
• Operable: 100% of website functionality accessible via keyboard alone (no keyboard traps), skip-to-content links, and sufficient time limits.
• Understandable: Predictable navigation structure, clear form field labels, and descriptive error validation messages.
• Robust: Valid HTML markup compatible with modern screen readers (JAWS, NVDA, VoiceOver) and assistive technology.
