Summary
New construction in unincorporated Glenn County's wildfire-prone areas has to meet the California Wildland-Urban Interface Code, adopted into county law by Code Section 15.72.137. The building official enforces it alongside the county's other adopted state construction codes, and the Board of Supervisors can grant limited modifications where strict compliance is impractical.
The 2025 California Code of Regulations Title 24, Part 7 also know as the California Wildland-Urban Interface Code, copies of which are on file as required by law, are hereby adopted and incorporated into this chapter by reference; are declared to be the wildland-urban interface code for the county and shall apply to the unincorporated areas of the County.
Full Breakdown
137 adopts the 2025 California Code of Regulations Title 24, Part 7, the California Wildland-Urban Interface Code, by reference as the wildland-urban interface code for the county, applying it to the unincorporated areas of Glenn County. 133, all most recently amended by Ordinance 1315 in 2022 and readopted for the 2025 code cycle under Ordinance 1337 in November 2025. 140 defines the officials who administer these adopted codes for Glenn County: the building official serves as the administrative authority, the Board of Supervisors sits as the board of appeals, and the fire department of whichever city or fire protection district covers the affected area functions as the bureau of fire prevention for enforcement purposes.
150 lets the Board of Supervisors modify the requirement on written application, provided the spirit of the code is preserved and public safety is not compromised; economic hardship or the cost of compliance alone is not sufficient grounds for a modification. 160 says the county's own provision controls.
Violations & Fines
Constructing or altering a building in an area covered by the Wildland-Urban Interface Code without meeting its requirements is a violation of the adopted code under Section 15.72.137, enforced through the county building official and treated like other Title 15 building code violations. As with other regulatory provisions of the county code, a first violation is an infraction, and a third violation of the same requirement within a 12-month period becomes a misdemeanor carrying up to a $5,000 fine, one year in county jail, or both, under Sections 1.12.010 and 1.13.010.
