What is WCAG?
The Web Content Accessibility Guidelines (WCAG) provide an international set of guidelines. They are developed by the Worldwide Web Consortium (W3C), the governing body of the web. That includes common destination-website components like:
- Event calendars, reservation widgets, and trip-planning tools (especially when added/managed by the site owner or their vendors)
- Online forms (newsletter signups, contact forms, permit applications, RFPs, etc.)
- PDFs and slide decks (visitor guides, meeting packets, agendas/minutes)
- Social media content after April 24, 2026.
These guidelines, the basis of most web accessibility laws in the world, are based on four principles, often referred to as POUR:
- Perceivable: Available to the senses (vision and hearing primarily) either through the browser or through assistive technologies (e.g. screen readers, screen enlargers, etc.)
- Operable: Users can interact with all controls and interactive elements using either the mouse, keyboard, or an assistive device.
- Understandable: Content is clear and limits confusion and ambiguity.
- Robust: A wide range of technologies (including old and new user agents and assistive technologies) can access the content.
Key deadlines
The compliance date depends on the population size of the state or local government:
- 50,000+ people: April 24, 2026
- 0–49,999 people: April 26, 2027
- Special district governments: April 26, 2027
After the deadline, governments must continue to keep web content and apps accessible.
