Colorado HB21-1110 Website Accessibility Compliance

HB21-1110 compliance is mandatory for Colorado state and local platform providers and content owners. HB21-1110 is mostly known as a website accessibility law but it will affect other digital assets because the new Colorado law applies to all technology – both internal and external.

The accessibility standards for HB21-1110 will come from the Colorado State Govenor’s Office of Information Technology (OIT). An interesting note is that Colorado makes note that previously, there was no formal process and little enforcement, but all indications are this new Colorado accessibility law will be strictly enforced.

All state agencies and local governments must be compliant with state standards by July 1, 2024.  Of note is the OIT will provide resources, training on the state standards, and tools to assist with accessibility, but agencies and local government will need to make the changes and improvements to their online content.


There are basically two categories for compliance. There is compliance for platform providers: Governor’s Office of Information Technology (OIT), SIPA ( websites), or other in-house development teams or vendors that are contracted to provide a platform.

Platforms are the underling technology that a website or application is built on.

And there is compliance for content owners: State agencies and county governments.

Content involves individuals and teams that create, publish and maintain content like text, links, images, forms, PDFs, documents and embedded third-party applications. 

Platform Providers

Platform providers, including OIT, SIPA and vendor partners, are required to provide a platform that is compliant with the most recently published W3C, Web Content Accessibility Guidelines (WCAG).

WCAG 2.1 AA is listed in the official Colorado state documentation but technically, the latest version is WCAG 2.2 AA. As 2.2 adds just 6 additional success criteria, we recommend continuing to WCAG 2.2 AA conformance.

Content Providers

Compliance in the creation and publishing of any online content and materials. 

  • Including but not limited to text, links, images, forms, PDFs, documents and embedded third-party applications. 

Content providers also must establish a written plan with OIT, as part of your annual IT Roadmap, for implementing the accessibility standards. This first plan was originally due on July 1, 2022.

The most important compliance deadline for 2024 is July 1, 2024.
