The Zone Zero Regulations Behind the Calabasas Requirements
Three laws, one Zone 0 rule
Each statute added a layer. Together they define what the first five feet around a Calabasas home must look like.
The zone is born
Created the ember-resistant zone: the first 5 feet around structures in Very High Fire Hazard Severity Zones must be kept free of combustible material, once the Board of Forestry finalizes the details.
The process accelerates
Pushed the stalled rulemaking forward and clarified who implements what, sharpening the line between the state framework and local enforcement.
The phase-in takes shape
Refined the compliance structure: phased deadlines for existing homes, immediate requirements for new construction and rebuilds, and room for local jurisdictions to set Phase 2 schedules.
The April 17, 2026 Board of Forestry draft is the most current regulatory text. It confirms the education-first enforcement posture, scales back some of the earlier blanket vegetation restrictions, and leaves Phase 2 timing to the local Authority Having Jurisdiction. Final regulations are expected late 2026.
In Calabasas, the county fire code is the one that counts
The state writes the floor. The specifics that reach your parcel come through the Los Angeles County Fire Department, which provides all fire services to Calabasas by contract through the Consolidated Fire Protection District. County fire prevention staff, working from the Calabasas Fire Prevention Office on Agoura Road, run the defensible space inspections that Zone 0 will ride on.
One more local wrinkle: CAL FIRE published a new Fire Hazard Severity Zone map for Calabasas on March 24, 2025. Your obligations follow the current map, not the one from a decade ago.
Regulation questions from Calabasas homeowners
Is Zone Zero law right now in Calabasas?
The statute exists (AB 3074 passed in 2020), but the detailed rules homeowners must follow are still in draft. The April 17, 2026 Board of Forestry draft is the most current text, and final regulations are expected late 2026. Once adopted, new-fence and rebuild rules apply immediately.
Does the City of Calabasas write its own Zone 0 rules?
The state sets the floor, and the local jurisdiction sets the specifics. In Calabasas, fire code enforcement runs through the Los Angeles County Fire Department under the city's fire services contract, so county fire prevention standards are what an inspector will apply on your parcel.
My parcel got remapped in 2025. Does that change what applies to me?
Possibly. CAL FIRE published a new Fire Hazard Severity Zone map for Calabasas on March 24, 2025. Zone 0 requirements attach to parcels in Very High zones, so your current mapped status, not the old map, determines your obligations. Check your address before assuming anything.
What happens if I do nothing?
Enforcement is education-first under the April 2026 draft, meaning notices and correction timelines come before penalties. But LA County Fire already inspects defensible space annually in the hazard zones, so Zone 0 items will show up on existing inspection visits once regulations are final.
