Colorado Wildfire Code Changes & Their Impact on Home Siding
Colorado has seen a significant rise in wildfire activity, leading to new statewide building standards aimed at improving home safety. The Colorado Wildfire Resiliency Code (CWRC), adopted in 2025, introduces requirements that directly impact siding, roofing, and exterior materials.
What is the Colorado Wildfire Resiliency Code?
The CWRC establishes consistent wildfire-resistant construction standards across Colorado, especially in Wildland-Urban Interface (WUI) areas. It applies to new construction and major remodels, focusing on reducing ignition risk from embers, heat, and flames.
How the Code Impacts Siding
The new code requires noncombustible or ignition-resistant siding in many areas. Common compliant materials include fiber cement, stucco, metal siding, masonry, and fire-retardant-treated wood. Traditional wood siding is no longer widely acceptable without treatment.
Vinyl siding is limited and must often be installed over fire-rated assemblies. Overall, siding must work as part of a complete exterior system including soffits, vents, windows, and decks.
Impact on Existing Homes
Existing homes are not required to immediately replace siding. However, any major remodel or siding replacement must comply with current codes. Insurance and resale considerations are also driving homeowners to upgrade sooner.
Why Siding Matters
Siding plays a critical role in wildfire defense. Fire-resistant materials help prevent ignition from embers, slow flame spread, and improve overall home survivability during wildfire events.
