Local Enforcement: Zone Zero Across San Diego County
A dozen local authorities, and no statewide Zone 0 floor
As of September 19, 2026 there is no statewide Zone 0 regulation in force in California. What you follow is the Authority Having Jurisdiction closest to the parcel. Municipal departments in incorporated cities, independent special districts, Heartland Fire & Rescue as a joint powers authority, and San Diego County Fire Protection District in much of the unincorporated area. Incorporated cities do not inherit the county 2023 Zone 0 section.
Every jurisdiction below has its own dedicated guide with the Authority Having Jurisdiction, local fire history, and community-specific FAQ.
Poway
Poway Fire Department. The City of Poway runs its own full-service municipal fire department rather than contracting out to the county, so Zone Zero inspections, permitting, and enforcement for Poway parcels run through Poway Fire Department directly.
Ramona
San Diego County Fire Protection District. Ramona's fire protection transitioned from the long-serving Ramona Municipal Water District Fire Department into the San Diego County Fire Protection District, which contracts with CAL FIRE for staffing. RMWD's fire-service history still shapes how the community understands its own risk.
Alpine
Alpine Fire Protection District. Alpine Fire Protection District has served the community as its own independent special district since the late 1940s, with its own elected board separate from the county's consolidated fire authority.
Julian
Julian-Cuyamaca Fire Protection District. Julian-Cuyamaca Fire Protection District is an all-volunteer independent special district and, notably, the only fire district in San Diego County that has not joined the countywide San Diego County Fire Authority consolidation. Local governance of fire service here is genuinely different from the rest of the county.
Scripps Ranch
San Diego Fire-Rescue Department. Scripps Ranch is a neighborhood within San Diego city limits, so Zone Zero enforcement runs through San Diego Fire-Rescue's Community Risk Reduction Division, the same as the rest of the city.
Fallbrook
North County Fire Protection District. North County Fire Protection District is an independent special district covering Fallbrook and neighboring Bonsall, separate from both the city departments to the south and the county fire authority.
Rancho Santa Fe
Rancho Santa Fe Fire Protection District. Rancho Santa Fe Fire Protection District is an independent, well-resourced special district serving the unincorporated community, including the architecturally covenant-controlled area known locally as The Ranch.
Escondido
Escondido Fire Department. Escondido Fire Department enforces Zone Zero for city parcels and already runs its own formal Defensible Space Certification program, giving Escondido homeowners a documented, city-issued compliance record separate from a contractor's word.
El Cajon
Heartland Fire & Rescue. El Cajon's fire service runs through Heartland Fire & Rescue, a joint powers authority that also covers La Mesa, Lemon Grove, and San Miguel Fire Protection District territory, an unusual multi-city governance structure among San Diego County's fire agencies.
Chula Vista
Chula Vista Fire Department. Chula Vista Fire Department is the city's own full-service municipal department and runs a dedicated Fuels/Hand Crew Program: a crew whose job is wildland fuel reduction work along the city's open-space edges, alongside the department's Ready Set Go wildfire-preparedness outreach.
Carlsbad
Carlsbad Fire Department. Carlsbad Fire Department is the city's own full-service municipal department. Coastal Carlsbad carries lower wildfire risk than San Diego County's inland communities, but the department's inland and eastern coverage area is a different story.
San Marcos
San Marcos Fire Department. San Marcos Fire Department is the city's own full-service municipal department, covering the city including the California State University San Marcos campus and the surrounding residential hillside communities.
San Diego Fire-Rescue Department
Homeowners within the City of San Diego, including Scripps Ranch, Linda Vista, Clairemont, Otay Mesa, San Ysidro, and Ocean View Hills, fall under San Diego Fire-Rescue's Community Risk Reduction Division. The division runs the city's existing brush management program and layers Zone 0 inspections on top of it. Direct line: (619) 533-4388.
