Rocklin, CA Fire Regulations: Wildfire Zones (2026)

Chapter 8.11, Fire Hazard Severity Zones, was added by Ordinance No. 1190 on June 10, 2025. Section 8.11.010 designates the FHSZ map developed by the California Department of Forestry and Fire Protection under Government Code Section 51178 as the city's own map, incorporating by reference a document titled "Fire Hazard Severity Zones as identified by the State Fire Marshal in the City of Rocklin," which the city posts electronically at rocklin.ca.us/FHSZ. Because the zone lines drive which parcels fall under the stricter Chapter 8.10 defensible-space and Title 15 wildland building standards, Section 8.11.020 resolves any parcel that carries more than one FHSZ designation by applying the single highest, most restrictive zone to the whole lot rather than splitting enforcement by portion of the property.

This matters for lots along Rocklin's foothill edges near Quarry Park and the granite quarry areas, where zone boundaries can bisect a single assessor's parcel. The map itself is not printed in the municipal code; it is adopted by reference and maintained on the city's website, so property owners confirm their exact zone status there rather than in the code text. Administration and enforcement of the FHSZ designation feed into the separate defensible-space and vegetation-management nuisance procedures already codified in Chapter 8.10, including the fire chief's inspection, notice and abatement authority described in that chapter.
