Much of unincorporated Jefferson County lies in the Wildland-Urban Interface. Properties in the WUI Overlay District (generally above 6,400 feet elevation) face defensible-space standards and wildfire-mitigation requirements tied to the County Zoning Resolution and building permits.
Jefferson County's foothills and mountain communities—Evergreen, Conifer, Ken Caryl, and unincorporated areas near Golden—sit in high wildfire-hazard terrain. The County maps a Wildland-Urban Interface Overlay District covering land generally above 6,400 feet, where wildfire-mitigation and defensible-space standards (based on CSU Extension Fact Sheet 6.302 and referenced in the Zoning Resolution) apply. Building and certain mitigation activities in the overlay can require a Defensible Space Permit and inspection by a County-approved forester. The County also operates a Wildfire Commission and slash-collection program to reduce fuels. Residents should verify whether a parcel is in the WUI overlay before building, since it affects setbacks, materials, and required vegetation clearance.
Non-compliance in the WUI overlay can delay or block building permits and trigger Planning & Zoning enforcement until defensible-space standards are met.
