Santa Clarita is a city built where canyons meet
Wind-driven embers can land well ahead of a fire front. They land in bark mulch, wood fences, and dry plants pressed against siding. That is how homes are lost: from the ground up, in the first five feet.
Santa Clarita has lived this twice in a decade. The 2016 Sand Fire burned more than 41,000 acres on the city's eastern edge and destroyed 18 homes, with Sand Canyon and Placerita Canyon under evacuation. Three years later the 2019 Tick Fire pushed into Canyon Country neighborhoods and forced tens of thousands of residents out overnight.
If your home backs open space anywhere from Sand Canyon to Newhall Pass, the first five feet is the highest-leverage place to act, whether or not a Zone 0 rule ever applies to your parcel.

As of September 19, 2026 there is no statewide Zone 0 regulation in force in California, and we have not identified a local Zone 0 ordinance for Santa Clarita. Existing defensible-space law still applies.
Existing law
PRC §4291 and Gov. Code §51182 already require roofs and gutters to be kept clear of leaves and needles and branches within 10 feet of a chimney outlet to be removed.
Statewide Zone 0
The Board of Forestry approved a draft on August 19, 2026. OAL file 2026-0828-03E is listed as withdrawn on September 8, 2026. There is no statewide effective date and no phase-in clock.
No local Zone 0 ordinance identified
As of September 19, 2026 we have not identified one. That is not a claim that none exists: our check covered the LA County Fire program page and targeted searches, not the city's full municipal code.
Harden the first five feet
Clear combustibles, choose non-combustible ground cover, and consider ember-resistant vents. LA County Fire's Defensible Space page also lists a 100-foot defensible-space radius as a recommendation.
LA County Fire is Santa Clarita's fire authority
The Los Angeles County Fire Department Defensible Space program covers 60 incorporated cities plus unincorporated LA County, and the county's program page lists Santa Clarita. That page does not use the term Zone 0 as a requirement: it lists chimney clearance as required and a 100-foot defensible-space radius as a recommendation. We have not identified a Santa Clarita local Zone 0 ordinance.
Local alternatives to the statewide draft may be adopted in the future, so confirm with LA County Fire and the City of Santa Clarita before acting on any deadline. Source: fire.lacounty.gov/fire-hazard-reduction-programs, checked September 19, 2026.

Is Zone 0 a statewide law in California?
As of September 19, 2026 there is no statewide Zone 0 regulation in force in California. The Board of Forestry approved a draft on August 19, 2026, but the emergency filing (OAL file 2026-0828-03E) is listed as withdrawn on September 8, 2026. Existing law (PRC §4291 and Gov. Code §51182) still applies, including keeping roofs and gutters clear of leaves and needles.
Who is the fire authority in Santa Clarita?
The Los Angeles County Fire Department. The county’s Defensible Space program page lists Santa Clarita among the cities it covers. That page lists chimney clearance as required and a 100-foot defensible-space radius as a recommendation, and it does not use Zone 0 as a requirement.
How is the first five feet different from the wider defensible space around my home?
Zone 0 is the innermost band, 0 to 5 feet from the structure. It covers fences, mulch, firewood, and stored items as well as plants. The wider defensible space is the ring beyond it; LA County Fire recommends a 100-foot radius. Clearing the first five feet is Recommended now, not Required now.
Should I wait for a deadline before clearing the first five feet?
No deadline has been set. There is no statewide effective date, and we have not identified a Santa Clarita Zone 0 deadline. Hardening the first five feet is Recommended now because it lowers ember risk whether or not a rule is ever adopted.
