Zone 0 in Santa Barbara County: who requires it, and who pays for it

Fact-checked August 23, 2026·Sources at the end of this article

Correction: the county does have a Zone 0 provision, and we were reading the wrong code

Added August 30, 2026. This page has said that Santa Barbara County's Board of Supervisors has no Zone 0 rule, on the basis that its 2026 fire code is a draft containing no Zone 0, ember or fence provision. The fire code part of that is still true. The conclusion was wrong, because the county's Zone 0 material is not in its fire code.

It is in County Code Chapter 10, Article XIX, the Primary Wildland-Urban Interface Code, which Ordinance No. 5270 repealed and reenacted in its entirety on November 18, 2025. It is codified, current through July 30, 2026, and in force. Not a draft.

Why we missed it, which is worth saying because it is now a repeatable mistake. The 2025 California code cycle created a standalone Wildland-Urban Interface Code at Part 7 of Title 24, and Zone 0 material moved into it. Reading a county's fire code and concluding it has no Zone 0 rule was reasonable in the 2022 cycle and is a trap in this one. We made the same mistake in San Diego County within the same week, where the 2026 Consolidated Fire Code contains no Section 4907 and no mention of Zone 0 at all, because it moved to the WUI code.

Here is what the county's article actually contains. First, a definition:

"ZONE 0. A five-foot ember-resistant area required around structures in high-fire-hazard zones to reduce home ignition from wind-blown embers during wildfires. Zone 0 regulations require the use of hardscaping like concrete or pavers, removal of dead plants and debris from roofs and gutters, clearing of combustible items from decks and porches, and the replacement of combustible fences attached to the home with non-combustible alternatives."

Santa Barbara County Code Chapter 10, Article XIX, Primary Wildland-Urban Interface Code, as reenacted by Ordinance No. 5270, § 1, November 18, 2025

Second, an operative amendment to Section 603.3.1, setting out what a Vegetation Management Plan must contain: "Identification of ground coverings within the 5-foot… to 30-foot… zone, with adherence to PRC 4291 within the ember resistant zone (Zone 0) from 0-foot… to 5-foot… from all structures."

Why this still does not put the county on our register

Read those two together and the shape is clear. The county's own operative duty is a plan-content requirement pointed at Public Resources Code section 4291. The fence sentence sits inside a definition, describing what Zone 0 regulations require, rather than inside a provision requiring anything of a named person on a named date. We do not treat a definition as a freestanding obligation, and we would rather say that plainly than bank a fence sentence we cannot stand behind.

What it does mean is that Santa Barbara County belongs on the list of local codes whose requirements are wired to state law by reference. We track those separately, because a code that points at PRC 4291 for its ember-resistant zone changes meaning on the day the statewide rule takes effect, without the Board of Supervisors voting again. Santa Barbara is the first one we have found in a 2025-cycle wildland-urban interface code rather than in an older fire or abatement chapter, which suggests it will not be the last.

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

In force now. Montecito Fire Protection District, in its own words, "has local Zone 0 requirements currently in effect for New Buildings and additions to Existing Buildings as described in the Development Standard #2." The hook is Ordinance No. 2025-02, which adopts the 2025 fire code and the district's Development Standards by reference. It passed November 17, 2025 and takes effect "thirty (30) days after final passage," which is December 17, 2025 by our arithmetic. Note the shape: a district development standard pulled into a fire code ordinance, not a free-standing Zone 0 ordinance. Nobody here has passed one of those. One note on our own count: Montecito is one of the thirty-five rows on the register. Our status tracker is where that number lives.

Adopted, not yet in effect. The statewide regulation, the one that will eventually reach existing homes, was approved August 19, 2026, and Office of Administrative Law review and Secretary of State publication are still ahead of it. Our timeline and enforcement guide covers what follows.

Where the statewide rule will reach in this county

Two legal tracks run in parallel and they are not the same law. The State Responsibility Area (SRA) is land where the state carries financial responsibility for wildfire protection, and defensible space there runs on Public Resources Code §4291; the Local Responsibility Area (LRA) is city and local district ground, running on Government Code §51182. Montecito's ordinance already carries a forward reference to the SRA track: its §604.3 lists California Code of Regulations Title 14, Section 1299.03 among the laws defensible space must comply with. That is a citation, not a claim that the state rule is effective today.

This county holds a great deal of SRA: its fire department is one of six CAL FIRE Contract Counties, and "As a Contract County, SBCFD protects 670,677 acres of SRA." On the local side what counts is Very High Fire Hazard Severity Zones (FHSZ, the hazard classes CAL FIRE maps). Montecito's November 2025 standards summarize the coming state requirement as reaching "all parcels within State Responsibility Areas and Very High Fire Hazard Severity Zones in Local Responsibility Areas," though the same passage also forecast it would take effect "January 1, 2026, for new construction," which it did not. Our address lookup walkthrough will tell you which track, if either, your parcel sits on.

CAL FIRE's March 10, 2025 release gave local agencies 120 days to adopt the updated zones, which they may raise but not lower. Only three jurisdictions here carry a figure in every column of the state acreage table, so those are the only three we print.

Lompoc's Very High acreage came out roughly nine times its 2011 figure. The City of Santa Barbara is the one jurisdiction in the table whose Very High acreage fell.

Up to $10,000 in Montecito, and exactly how the money works

Nearly every detail of this program is a condition. Montecito Fire's Home Hardening Assistance Program will "issue a reimbursement check to the property owner for eligible expenses, with a maximum assistance amount of up to $10,000," once per property, and only after you have paid: "Homeowners are responsible for completing and paying for eligible projects before requesting reimbursement." Eligible work reaches back to January 1, 2025. Fencing is named, not implied: the eligible-actions list carries a section headed "Upgrading Wood Fences."

Replace wood fencing with non-combustible materials, prioritizing the first 5 feet closest to the home. Using non-combustible fencing or gates where they attach to the structure reduces the risk of a burning fence igniting the home's exterior. Non-combustible fencing materials are often available in eight-foot sections, and using the full length is recommended for optimal protection.

Montecito Fire Protection District, Home Hardening Assistance Program, eligible retrofit actions

A photo caption shows the work funded in practice: "Example of the first 5' feet of combustible fence replaced with non-combustible." A companion section, headed "Zone 0 Compliance" in the district's own words (we never describe a product or a finished job that way), covers the ground around the fence, from gravel and pavers to combustible pergolas and decks. Our guide to noncombustible fence materials walks through the qualifying options: aluminum, steel, wrought iron, chain link, masonry, concrete and stone.

The free inspection is Step 1, and it is a gate. Applicants "must be willing to participate in a Defensible Space Inspection by a Montecito Wildland Fire Specialist," which produces "an individualized home assessment report" sorting measures into required, recommended and optional.

Then the paperwork, and the caveat. Reimbursement takes before-and-after photographs, an invoice showing the date, description, property address and the contractor's license number, and proof of payment. The program says outright that it is competitive: "Because funding is limited, submission of an application does not guarantee approval or reimbursement," and "projects located in lower-risk areas are less likely to be selected." The application page names the pot: "With a dedicated allocation of $60,000 from the fire department." Divide that by the $10,000 cap and you get six properties, but that arithmetic is ours: no award count, deadline or application window is published. On August 20, 2026 neither page carried a closure notice and the form was live, which is the whole basis for our finding that it is open. Call 805-969-7762 before you spend.

The rest of the county's money, and a deadline that is nearly here

The Santa Barbara County Fire Safe Council's Home Hardening Rebate reimburses homeowners "living in Firewise Communities in Socal Edison territory for up to $5,000," first come first served, on a Southern California Edison grant. Its qualified list includes "Replacement of fences with non-combustible materials (metal, masonry, etc) up to 5 feet from the home."

Two things about it, in order of cost to you. It is paused: the banner posted June 24, 2026 still stood on August 20, 2026, and new applicants "will be placed on a waitlist." Bigger than the pause is the calendar. "The deadline to complete all eligible work and submit reimbursement documentation is August 31, 2026," eleven days after this article's fact-check date, and the page never reconciles the waitlist with the deadline. If you are enrolled, the rule that catches people is written down: "Wait to plan or start work until we have sent you written approval."

Elsewhere the county offers time rather than money: free home fire safety inspections from County Fire, voluntary inspections from the City of Santa Barbara, and Montecito's chipping program, whose 2026 season is over. The state's California Wildfire Mitigation Program lists six project areas, none here. Our roundup of who pays tracks the rest.

What Montecito's rule requires, and who it binds

Development Standard #2 heads its list "Zone 0 Requirements: The items below are requirements applicable to New Structures. The bold items (b, d & e) are also applicable to Existing Structures." The fence and gate items read:

f. Combustible gates shall not be directly attached to a building or structure. g. Fences that are directly attached to a building or structure shall have a 5 foot non-combustible span at the point of attachment. No new sections of combustible fence are permitted within 5 feet of a building or structure including an attached deck.

Montecito Fire Department Development Standards, November 2025 (updated 02.02.2026)

Read the typography, because it is doing legal work. Items f and g are not bold, so they reach new structures and, per the advisory notice, additions. What reaches existing structures is item b (tree clearance from chimney and stovepipe outlets), d (roof and gutters kept clear) and e (nothing combustible under decks, balconies and stairs). Building, adding on, or attaching a new fence: the five-foot noncombustible span applies now, and our five-foot transition explainer shows what it looks like. House unchanged: nothing here orders you to replace an old wood fence. Enforcement matches that scope. Montecito's hazard abatement violation list runs to twenty items, from grass and weeds to Knox switches, with no Zone 0 or fence violation on it; the annual sweep is not written to enforce this rule.

The county standard that says "shall," and the question we could not answer

County Fire's Development Standard #6 (Defensible Space), revised 02/19/2026, contains a Chapter 5 headed ZONE 0 in mandatory language: "5.4.5 Fences and gates within this zone shall be non-combustible," plus bans on combustible mulch, vegetation and firewood. The identical text appears in the June 13, 2024 revision, so it is not new.

The trouble is the applicability clause: "Zone 0 is tied to legislation from the State. Any building constructed after July 1, 2024, or any landscapes modified after that date, shall comply with this Chapter." No statewide Zone 0 regulation was effective on July 1, 2024 and none is effective now, so that hinge turns on a date that has never existed. Nor could we confirm whether the department applies Chapter 5 at plan review, at inspection, or at all. So we say only this: the county publishes a mandatory-language Zone 0 chapter with a noncombustible fence requirement, and you should ask how it reaches your parcel ([email protected]).

One detail in the same standard cuts the other way. Its ignition-resistant construction list allows fences and gates within five feet of a structure to be "of non-combustible material or pressure-treated exterior fire-retardant wood." Fire-retardant treated wood (FRTW) does not pass ASTM E136, the noncombustibility test behind the state text approved on August 19, 2026, so satisfying the county's list is not the same as satisfying the state's. See our fence requirements guide.

Where there is no Zone 0 rule at all

The clean negatives matter as much as the rules, because we would rather you did not spend money on a requirement that is not there. The Board of Supervisors has adopted nothing: its 2026 fire code was announced on April 21, 2026 for a May 5 first reading, every attachment we read is labeled a draft, and the text returns no hits for "zone 0," "fence" or "1299.03." Carpinteria-Summerland's Ordinance No. 2025-02 defines "COMBUSTIBLE FENCING" and then requires nothing of it, and its vegetation standard defines Zone 0 without imposing anything inside it. The City of Santa Barbara now reads negative from its own adopted ordinance rather than its department pages: Ordinance 6199 adopts the 2024 International Fire Code, the 2025 California Fire Code and the 2025 California Wildland-Urban Interface Code with local amendments, and the amendments it writes for its own High Fire Hazard Area are ignition-source rules, smoking, spark arresters, off-road engine exhaust and where ashes may be dumped, rather than materials rules; its three fence provisions concern school grounds and hydrant clearance. The city sets defensible space by distance band, 30 to 150 feet, with no five-foot zone. It is also, like a growing number of California cities, an adopter of the 2025 Wildland-Urban Interface Code, which on the reading one city attorney has published would carry the state's Zone 0 requirements by reference once they take effect; Finding two of the survey explains why we do not count that as a rule in force. Even the countywide fire season release only asks residents to "Use non-combustible landscaping materials in this area when possible," and those last three words are the tell. What does get enforced countywide is brush clearance: County Fire's Hazard Reduction Program, where "A misdemeanor citation is issued to all property owners that do not comply by the compliance date." What it measures is a hundred feet of vegetation, not five feet of hardscape. Our roundup of local Zone 0 ordinances covers other jurisdictions.

Claims we could not verify

• Whether the Board of Supervisors adopted the 2026 fire code, or met its announced June 11, 2026 effective date. Our only source announces a future first reading of a draft.
• Whether County Fire's Chapter 5 is enforced, and against whom. A call to the department will settle it faster than we can.
• Whether the Montecito program has a window, a deadline, a fiscal-year reset, or how many awards it makes. None of it is published.
• Whether the Fire Safe Council rebate reopens after August 31, 2026. The banner promises contact "when the program reopens" and the deadline sets a hard cut-off. The page does not reconcile the two, so neither will we.
• State acreage for Buellton, Carpinteria, Goleta, Guadalupe, Santa Maria and Solvang. Those rows hold fewer numbers than there are columns, and nothing says which class a bare number belongs to. We will not guess, so they are absent from the table above. Guadalupe's blank row is consistent with no mapped LRA zones, but the source does not say so.
• Lompoc. Both city fire department pages returned HTTP 403 and were never loaded, so we claim nothing about their contents, including when Lompoc adopted its zones.
• Final map adoption dates for the City of Santa Barbara and Santa Maria, and any supervisors' ordinance adopting the maps for the unincorporated county. None was located.

What this means for you

• In Montecito, book the free inspection before you spend anything. Call 805-969-7762. It is Step 1, a required field on the application, and it produces the report naming what the district considers required.
• Keep the paperwork as you go. Reimbursement turns on before-and-after photos, an invoice carrying the date, description, address and contractor's license number, and proof of payment. A good job documented badly does not get paid.
• Treat $10,000 as a ceiling, not an expectation. The money is competitive against a $60,000 allocation, and applying does not guarantee approval.
• In a Firewise community in Edison territory, watch the calendar rather than the waitlist, and never start work without written pre-approval.
• Everywhere else, nothing in force today tells you to replace an existing fence. Walk your first five feet with our Zone 0 self-assessment and work the Zone 0 checklist, which flags what you do not need to buy as plainly as what you do.

How often CAL FIRE inspects here

CAL FIRE's dashboard shows 6,507 parcels in Santa Barbara County, of which 6,153 were compliant. We are not turning that into a compliance rate, because the row does not behave like the single month the dashboard says it covers: it is 18 percent of every inspection in California and nearly three times the next county, while contract counties with much larger programs show a few hundred. We read it as a bulk posting over a longer period. The numbers are the dashboard's; the doubt is ours, and we would rather name it than quietly use the figure.

Two things this does not tell you. These counts cover inspections by CAL FIRE and Contract Counties inside the State Responsibility Area only, so work done by local fire agencies in the Local Responsibility Area is absent entirely. And none of these inspections is checking Zone 0: they are inspections against the defensible space rules in force today, which reach from the structure out to one hundred feet and contain no ember-resistant zone requirement. See the full inspection figures and what they mean, read from CAL FIRE's public dashboard on August 23, 2026.
