Zone 0 in Marin County: the money is in place, the rule is not

Fact-checked August 20, 2026·Sources at the end of this article

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

That is the usual shape of a county guide. Marin breaks it. As of August 20, 2026 we could not find a Zone 0 or ember-resistant-zone requirement in force anywhere in the county, and the statewide rule adopted the day before is not yet in effect. Three things get mistaken for a local Zone 0 rule:

• San Rafael's vegetation standard. Municipal Code Chapter 4.12 sets citywide rules for "the immediate zone (zero to five feet (0-5′) from any structure)." It permits plants, and it contains no fence or gate clause.
• Material rules for new construction. On December 9, 2025 the Board of Supervisors adopted Ordinance No. 3838, which per county staff added "a restriction on the use of FRTW for new construction within all FHSZ and WUI fire areas." Fire-retardant-treated wood (FRTW) is lumber treated to slow ignition. The restrictions "include siding and other exterior building components." That is a wall-covering rule for new buildings: no ember-resistant zone, nothing about fences. A later staff report recommended undoing it, so see the unverified list below.
• Grants that pay for Zone 0 work. Three Marin programs will help fund a noncombustible fence section. An incentive is not a mandate.

One gap we cannot close: Novato Fire Protection District's ordinance index lists Ordinance 2025-04, adopting and modifying the 2025 California Wildland Urban Interface Code, and Ordinance 2025-01, designating fire hazard severity zones in local responsibility areas. Both are posted as image-only scans, and we could not extract a word of either. If a Marin Zone 0 rule exists anywhere, that is the likeliest place for it. Call the district and ask.

There was groundwork for something firmer. The MWPA work plan adopted May 15, 2025 proposed to "support required updates to local ordinances in response to direction from the State of California regarding Zone Zero." The plan that replaced it on May 21, 2026 carries no successor item, and neither document says why. The agency's public line today is a promise without a date: "Coming Soon! Stay tuned for upcoming programs to help residents with Zone Zero (the first 5 feet from your home)!"

Adopted, not yet in effect: the statewide regulation, the instrument that would carry fence and gate rules into Marin once it takes effect. It cleared the Board of Forestry on August 19, 2026 and still needs Office of Administrative Law review and publication by the Secretary of State, so no compliance clock is running. Our timeline and enforcement guide covers the phase-in; the local ordinance tracker lists the places that do have something in force. Marin is not among them.

Where the statewide rule will reach in this county

The regulation runs on two legal tracks. In the State Responsibility Area (SRA, land where the state holds financial responsibility for wildfire protection) it covers every hazard class, under Public Resources Code section 4291. In the Local Responsibility Area (LRA, city and district-protected land) it covers only mapped Very High Fire Hazard Severity Zones, under Government Code section 51182. A High-zone house in a city sits outside the rule; a Moderate-zone house in the SRA sits inside it.

Marin has plenty of SRA land and few SRA houses. Per the 2020 Community Wildfire Protection Plan the SRA "comprises more than half of the total land area in Marin," yet holds about 15,138 of the county's 96,042 parcels, most of them behind Marin County Fire (7,066), Southern Marin (2,590) and Novato (1,872). Marin is also one of six California "Contract Counties," where CAL FIRE "contracts with MCFD to provide wildland fire protection," so even on state land the agency at your gate is the county fire department.

For everyone else the question is whether a local map puts your parcel in a Very High zone, and Marin's agencies are at different stages. CAL FIRE released the updated LRA maps on February 24, 2025. Southern Marin Fire Protection District adopted them by ordinance on May 26, 2025, the only adoption we could confirm from an agency source. Central Marin Fire Authority received its maps the same day but its page does not say an ordinance followed, and the county's own LRA page still offers maps headed "Draft SRA/LRA Fire Hazard Severity Zone Maps," last updated April 17, 2025. Start with our address lookup walkthrough, then confirm with your agency.

What San Rafael's first five feet actually says

San Rafael is the one Marin jurisdiction with a mandatory citywide standard for the 0 to 5 foot band, required "for all properties in the WUI on or before August 1, 2021 and for properties outside the WUI by April 1, 2022." Section 4.12.030(C) requires the roof, gutters, decks, porches and stairways to be kept clear of accumulated leaves, needles and dead growth, then says this:

All vegetation within five feet (5′) of structure shall be well-irrigated and maintained to eliminate any dead or dying material build-up and trimmed to prevent contact with the structure. ... Single specimen trees shall be permitted when well-irrigated, limbed over five feet (5′) or one-third (1/3) of the tree height ...

San Rafael Municipal Code section 4.12.030(C)

Set that against the statewide Zone 0 concept and the gap is plain: San Rafael's first five feet permits irrigated vegetation and even single specimen trees. There is no noncombustible-material requirement and no fence or gate clause in the chapter. If someone tells you the city requires a metal fence section at the house, ask which code section says so. There is not one.

Measure C, and what it will actually pay toward a fence

Measure C, a ten-year parcel tax, passed in March 2020 "with 70.8% support of most Marin County voters (excluding Tiburon and Belvedere)." It "levies up to 10¢ per building square foot ($75 per multifamily unit) for ten years, providing $19,300,000 annually," and funds the Marin Wildfire Prevention Authority (MWPA), a joint powers authority of 17 member agencies. Two cautions before any dollar figure: Tiburon and Belvedere sit outside the taxing area, and every dollar runs through a free defensible space and home hardening evaluation.

San Rafael's conditions are as specific as its figures. An evaluation "must have been completed within 1 year of a grant application," pre-approval and a W-9 are required, and work by a contractor not registered with the city "will NOT be reimbursed." How long pre-approval holds your money is published two ways on that one page: "Funds are reserved for 90 days after pre-approval" under Rules and Requirements, and 60 days twice in the FAQ below it. Assume 60 and confirm with the fire department. A single parcel may receive at most $15,000 across the ten-year measure.

Doing the work yourself is allowed: the city will "reimburse for material costs if you plan on installing noncombustible fence panels yourself." One exclusion matters when you shop: "treated wood products do NOT qualify for reimbursement." Aluminum, steel, wrought iron, chain link, masonry, concrete and stone are the noncombustible families to price; our guide to noncombustible fence materials explains the test behind them.

The county-wide grant is harder to report honestly, because four agency pages publish four fiscal years of terms. The Board-adopted 2026-27 plan sets a $900,000 budget and pushes administration down to five zones, with San Rafael ($184,875) and Novato ($182,750) folding their shares into their own programs. It publishes no per-parcel cap and no income test, while the live grants page still shows 2024-25 terms and the Southern Marin and Sleepy Hollow pages show older $5,000 figures. Anyone quoting "$5,000 a year in Marin" is quoting a stale number, and one rule holds throughout: "the same work cannot be funded twice." Our who pays guide sets this in statewide context.

Novato: funded for this fiscal year, with no published window

The money is authorized. The 2026-27 work plan funds a Novato home hardening program at $650,000, vegetation management at $335,893.83, and Zone 0 vegetation removal at $150,000. The terms sit partly in that plan and partly on the district's page: a home hardening match up to $2,500 covering "wooden fences attached to the home in Zone 0 only"; a Zone 0 removal grant, "a reimbursable 50/50 matching grant, up to $1,000," which is "application-based and eligibility will be limited to residents who have received a full inspection by Novato Wildfire Mitigation Specialists"; and a defensible space vegetation grant with a $1,000 maximum.

What is not published is whether you can apply today. The district's grants page names no fiscal year and carries no dated banner. Its only status sentence reads: "Grants are awarded on a First come first serve for Novato Residents closing on June 15th at 5 pm or until funds are exhausted." We will not tell you that window is open, and we will not tell you it is closed, because neither is knowable from what has been published. Phone the district, or email Wildfire Mitigation Specialist Supervisor Yvette Blount at [email protected], before committing money.

Novato reimburses "already completed work only," the property needs a free evaluation "within the past year," and review runs "approximately 4-6 weeks" with payment another four to six. Unlike San Rafael, no W-9 is required.

Who inspects, and who can actually fine you

The MWPA says plainly that it is not the enforcer: "any enforcement of state or local regulations is the sole jurisdiction of your fire agency." Its evaluation report still matters, because "some issues identified may be required by law and must be corrected." San Rafael is the county's enforcement leader: a pre-citation, a $250 citation, a second $250 fine that forgives the first if the hazard is fixed in between, then compounding fines that "max out at $500/day." None of that is a fence penalty. It is vegetation, under Chapter 4.12.

Claims we could not verify

• "Marin County requires noncombustible materials where fences attach to structures." We found this only in a search snippet from a private architecture firm's blog. Nothing on any Marin fire agency page, city code or county code we loaded supports it, and a full-text search of San Rafael Chapter 4.12 returns no occurrence of "fence" or "gate." Fire Safe Marin calls noncombustible fencing "recommended." Do not act on the claim.
• What Novato FPD Ordinances 2025-04 and 2025-01 actually say. Both are listed by title on the district's own index, and both posted PDFs are image-only scans with no extractable text. Whether either creates a Zone 0 requirement is unknown to us. Ask the district before assuming it has one or lacks one.
• Whether Novato's grant window is open today. Funded, yes. Open, unknown.
• The current MWPA per-parcel cap and eligibility test. The adopted 2026-27 plan publishes a budget and zone splits but neither a cap nor a test, and the live page is stamped 2024-25. Which terms apply today is published nowhere we could load.
• The fate of the unincorporated county's FRTW restriction. A January 27, 2026 staff report recommended an ordinance allowing fire-retardant-treated wood again, "consistent with State code," on the February 10, 2026 consent calendar. We could not load any February 10 county record, so we take no position on the outcome.
• LRA map adoption in much of the county. Only Southern Marin's May 26, 2025 ordinance was confirmed. Unincorporated Marin still posts "Draft" maps, Central Marin's page stops short of saying an ordinance passed, and Kentfield, Ross Valley, Tiburon, Mill Valley, Larkspur, Corte Madera, Marinwood and Novato are unconfirmed.
• Whether San Rafael's refund program has a deadline. The page states none and shows no closure banner, which is not proof of an open window.
• Current SRA parcel counts. The figures above rest on 2018-2019 assessor data carried in the 2020 plan. A 2026 county plan is described as scheduled for adoption; we could not locate it.

What this means for you

• Do not buy a fence because you think Marin requires one. Nothing we could find in force here does. If you want the work anyway, sequence it around the grants, not a deadline that does not exist.
• Book the free evaluation, then get pre-approval. In San Rafael and Novato the evaluation is a precondition of funding, both reimburse completed work only, and San Rafael also requires a contractor registered with the city.
• Confirm the number, not the webpage. Marin's published grant terms disagree across four fiscal years. Email [email protected] or your own fire agency and ask what applies this week.
• In Tiburon or Belvedere? You are outside the Measure C taxing area. Southern Marin Fire District does say its jurisdiction includes the "Alto Richardson Bay Area within the Town of Tiburon," so ask the district where you stand.
• Plan the five feet, then decide what to buy. Run our Zone 0 self-assessment, work the Zone 0 checklist, and read what the adopted state rule asks of fences in our fence requirements guide and our explainer on the five-foot transition.
