Colorado Wildfire Resiliency Code Guidance

Download Builder Guide to the Colorado Wildfire Resiliency Code

Effective today, July 1, 2026, the CWRC establishes statewide minimum standards for construction and site development in designated Wildland-Urban Interface (WUI) areas, as required by Senate Bill 23-166.

The code represents a significant change for Colorado's development community by introducing requirements intended to reduce structure ignition risk through building hardening measures and defensible space standards.

For developers, builders, architects, engineers, and land use professionals, early integration of CWRC requirements into project planning will be essential to:

• Minimize permitting delays
• Reduce redesign and construction costs
• Improve project timelines
• Ensure compliance with the new statewide standards

CAHB has developed a practical guide that explains how properties are classified, outlines the key provisions of the code, and identifies important planning considerations for projects moving forward.

As communities continue to balance growth with wildfire resilience, understanding these new requirements will be an important part of successful project delivery.
