Full Breakdown
040, adopted under Ordinance 2025-04, clarifies enforcement of California Building Code Chapter 7A and California Residential Code Section R337, the state's materials and construction standards for exterior wildfire exposure. Rather than applying those standards only within a mapped Fire Hazard Severity Zone, Truckee designates the entire Town a Wildland Urban Interface (WUI) area and applies Chapter 7A and Section R337 townwide, regardless of a property's individual severity zone designation. 3 Exception 4 of the Residential Code are deleted and replaced so that roofing, siding, and window replacement no longer escape the wildfire standards. 8. 1).
Violations & Fines
Constructing, remodeling, or re-roofing in violation of the WUI materials standards is a Title 15 violation, an infraction with a fine of up to $500 and up to six months in the Town Jail per offense, with the Town also able to pursue the noncompliant condition as an abatable public nuisance independent of the criminal fine (15.02.050).
