Zone 0 in Ventura County: what applies where

Fact-checked August 19, 2026·Sources at the end of this article

Two sets of rules, and only one is in force today

In most of California, "Zone 0 is already required here" is a false claim. In Ventura County it is partly true, provided you are precise about who requires it, and for which buildings. As of August 19, 2026:

In force now: the Ventura County Fire Protection District (VCFPD) adopted Zone 0 through its 2025 Wildland-Urban Interface Code (Ordinance 34). Per the district: "Effective March 1, 2025, VCFD has implemented a full 5-foot Non-Combustible Zone 0 for New Buildings and Additions to Existing Buildings." The code also covers "installation of new landscape, and refurbishment of existing landscape areas," and the district's Standard 515 notes it has had Zone 0 requirements for new buildings since April 1, 2019.

Adopted, not yet in effect: the statewide regulation, the one that will add fence and gate requirements for existing homes once it takes effect. The Board of Forestry approved it on August 19, 2026. The package still has to clear the Office of Administrative Law, a review that includes a five-day public comment period, and be published by the Secretary of State, so no statewide compliance clock is running yet. Board staff said they would submit it as an emergency rulemaking package under the provisions of AB 1455 (2025) and expected it could become effective as early as September 2026. Our timeline and enforcement guide covers how the phase-in will work. The district's code anticipates the handoff, printing an advisory notice that "Any State regulation more restrictive than this ordinance... shall apply."

Where the statewide rule will reach in this county

The statewide regulation covers two kinds of territory: all of the State Responsibility Area (SRA, land where the state holds financial responsibility for wildfire protection), every hazard class included, and Very High Fire Hazard Severity Zones only in the Local Responsibility Area (LRA). A home in a High zone inside a city falls outside it; a home in a Moderate zone in the SRA falls inside. Our coverage explainer explains the distinction.

Ventura County has substantial SRA, with a wrinkle: it is one of California's six "Contract Counties," where per the 2023 Community Wildfire Protection Plan "SRA fire protection is provided by the counties under contract with CAL FIRE." Even in state-responsibility territory, the agency at your door is the Ventura County Fire Department. The SRA hazard maps took effect April 1, 2024; the district adopted the 2025 LRA maps by Ordinance 33, effective July 1, 2025. If a parcel spans two or more zones, the district applies the highest zone to the entire parcel.

Very High acreage, jurisdiction by jurisdiction

The Office of the State Fire Marshal's March 10, 2025 map release lists Very High acreage by jurisdiction, with the 2011 figures for comparison:

The headline is the unincorporated county, where Very High acreage jumped from 5,370 to 31,487. Ojai roughly tripled. Ventura, Oxnard, and Fillmore sit outside the district, running their own fire departments and adopting their own maps; the Ventura City Council adopted its map July 1, 2025, classifying more than 4,600 acres as High or Very High.

What the district's Zone 0 requires, and what it doesn't

The in-force rules are the 2025 VCWUIC and Standard 515, which describes Zone 0 as hardscape-only: "No plantings, vegetation, or combustible material of any kind are allowed in this zone. Install hardscape only: Rock, sand, decomposed granite (DG), dirt, pavers, concrete, etc."

For new buildings and additions, the code requires noncombustible fencing and gates in Zone 0, bans tree canopy within 10 feet, and prohibits combustible mulch, wood chips, and firewood. If you are building in the district, the fence question is settled; see our guide to noncombustible fence materials.

For existing buildings, the code lists restrictions that apply now: no combustible mulch or wood chips, no firewood, no vegetation underneath decks, no artificial grass, no new trees. Note what is not on that list: replacement of existing fences. That is the piece the state regulation will add once it takes effect. Standard 515 is explicit about when:

State regulations for Zone 0 are currently under development... that will affect EXISTING buildings within the applicable zones constructed prior to April 1, 2019. An anticipated 3-year phase in of these regulations will likely be implemented with full compliance, expected sometime in 2029.

VCFPD Standard 515, Defensible Space and Landscape Plan Submittal Requirements (revised effective January 1, 2026)

That squares with the adopted statewide regulation, under which fences on existing structures are a Phase 2 item: three years from an effective date that does not yet exist, or up to five on a local fire agency's timeline. Even then, the regulation does not require wholesale fence replacement. Existing combustible fences may remain and repairs may use combustible replacement materials. The noncombustible requirement lands on attached fences, full replacements, and new installations; details are in our fence requirements guide. One caveat on the fine print: the August 19 package posted in the board binder is the pre-meeting deliberative draft, and no certified "as adopted" text has been published yet, so treat provision-level wording as pending.

One more piece of county reality: on October 21, 2025, the Board of Supervisors unanimously passed a resolution (not an ordinance) urging the state to rethink its draft Zone 0 rules, restore local control, and fund implementation. Supervisor Jeff Gorell: "Sacramento's one-size-fits-all approach to maps and regulations ignores local realities." So the county's fire district enforces a Zone 0 code while its supervisors lobby Sacramento to soften the statewide version.

Claims we could not verify

• "Ventura County passed a Zone 0 ordinance." Not as most people mean it. We found no Zone 0 ordinance from the Board of Supervisors. The adopted requirements are district instruments, Ordinance 34 (the 2025 VCWUIC) and Standard 515, and trade-press references to a "Ventura County Zone 0 ordinance" almost certainly mean these. The only supervisors' action we found is the October 2025 resolution pushing back on the state draft.
• "VCFD will apply Zone 0 to High zones, not just Very High." Asserted by an advocacy site; not confirmed on any district source we loaded. Standard 515's stated applicability is SRA zones, LRA Very High zones, VCFPD Hazardous Fire Areas, and "any property as determined by the Fire Department."
• "60,000 Ventura County properties will fall under the state Zone 0 rules." A local news headline we saw only as a search snippet; the article is paywalled. Treat the figure as unverified.
• "VCFD protects 353,370 acres of SRA." Appears on Wikipedia-style sources only; no primary source confirms it. Contract-county status itself is verified.

Inspections, brush clearance, and free help

The district's enforcement vehicle is the Fire Hazard Reduction Program (FHRP), its annual defensible-space and weed-abatement program. Notices to abate are mailed April 20 each year, and owners "are expected to maintain their property free of fire hazards or nuisance vegetation year round." Contact: [email protected], (805) 389-9759. The same program handles AB 38 defensible-space reports for home sales in High and Very High zones. The City of Ventura runs its own FHRP with a June 1 brush-management deadline.

For help before an inspector arrives, five fire safe councils serve the county: Ojai Valley, Bell Canyon, Oak Park, Ventu Park, and the Ventura Regional Fire Safe Council covering all other areas. Per the district, "Free Home Wildfire & Hardening Assessments are also provided by the Fire Safe Councils in locations prone to wildfires." The Ventura Regional council also runs chipping, Firewise USA, and resident grant programs. As in every county, most fuels-reduction grants pay for vegetation work, not hardscape or fencing; confirm scope with each program.

What this means for you

• Find your zone first. Use our address lookup walkthrough to see whether you are in the SRA, an LRA Very High zone, or neither. Remember: the highest zone on a split parcel applies to all of it.
• Building or adding on in the SRA, an LRA Very High zone, or a VCFPD Hazardous Fire Area? The noncombustible five-foot zone, fencing and gates included, applies now, and has in some form since 2019.
• Existing home in the SRA or a Very High zone? The district's in-force list already bars combustible mulch, firewood, and vegetation under decks in your first five feet. Fence requirements will arrive with the state rule once it takes effect; the district expects full compliance for older homes around 2029. You have runway; use it to plan rather than panic-buy. Run our Zone 0 self-assessment and work through the Zone 0 checklist.
• In Oxnard or Port Hueneme? The statewide regulation as adopted likely does not reach you: Oxnard has no Very High zones on the 2025 maps and Port Hueneme has none at all. Verify your own parcel anyway.
• The vote happened; now watch the OAL review. The Board approved the regulation on August 19, 2026, and the package goes next to the Office of Administrative Law for expedited review, including a five-day public comment period, before the Secretary of State publishes it. Nothing about the remaining timeline is guaranteed; the Board has missed deadlines before. The status tracker reflects changes as they happen, and our California Zone 0 fencing guide covers the fence rules in depth.
