Zone 0 status in San Francisco County
San Francisco County doesn't have its own local ember-resistant zone ordinance on file - it follows California's statewide Zone 0 rule (PRC §4291 / AB 3074), adopted by the Board of Forestry on August 19, 2026 and pending final state filing before it's legally effective. Your property's actual defensible-space requirements today depend on its Fire Hazard Severity Zone, not the county line.
Fire protection in San Francisco County San Francisco County's wildland fire protection falls under the San Mateo-Santa Cruz Unit (CZU), headquartered well south of the city in Felton — reflecting how little of the county is wildland to begin with, compared with most of California's other counties.
SourceState Responsibility Area (SRA) excludes land inside incorporated city limits by law (Public Resources Code §4127) - so within the county, SRA generally means the unincorporated area; incorporated cities rely on their own city or district fire department instead, whether or not CAL FIRE also protects the county's SRA.
Statewide rule adopted, pending final filing The statewide Zone 0 rule (adopted August 19, 2026, pending final state filing) applies here based on your property's Fire Hazard Severity Zone, not a county-wide mandate.
