A homeowner in Sierra Madre sent me three quotes last week for the same job: "Zone 0 compliance." They ranged from $2,400 to $18,900. All three were for the same 1950s ranch on the same quarter-acre lot.
The spread wasn't dishonesty. It was scope. The $2,400 quote was a landscaper pulling bark mulch and juniper. The $18,900 quote included a fence transition, a deck skirt, eleven vents and a gutter system. Both of those are Zone 0 work. Only one of them is what most people picture when they hear the phrase.
What got approved, and when it actually bites
On August 19, 2026 the Board of Forestry and Fire Protection voted unanimously to adopt the final Zone 0 regulations — the first statewide standard in the country governing the five feet immediately around a house. The rules went to the Office of Administrative Law in early September, and officials have pointed to roughly the end of September 2026 for them to become legally effective.
The statute underneath is AB 3074 (2020), which created the "ember-resistant zone" concept, with SB 63 (2023) and Governor Newsom's Executive Order N-18-25 in February 2025 pushing the rulemaking to a finish after the Eaton and Palisades fires. The rationale is the same number that has driven every home-hardening rule of the last decade: somewhere near 90 percent of homes lost in wildfire ignite from wind-blown embers, not from the flame front. The five feet is where those embers land and find something to burn.
The phase-in is gentler than the 2024 and 2025 drafts that had Altadena residents planting protest signs in their front yards:
| Who | When | What is required |
|---|---|---|
| New construction | Effective date | Full compliance at permit application. Includes every Eaton Fire rebuild still in plan check. |
| Existing homes, day one | Effective date | Roof and gutters clear of debris. Dead and dying branches removed. Ten feet of clearance from chimneys, nothing under eaves. |
| Existing homes, Phase 1 | Within 3 years | All combustible material out of the five feet: bark mulch, wood chips, leaf litter, firewood. Under-deck and under-stair space cleared. Ladder fuels removed, five feet of clearance above the roof. |
| Existing homes, Phase 2 | 3 years, extendable to 5 by the local fire agency | Vegetation-free buffers at walls, windows and eaves. Plant allowance compliance. Noncombustible fence and gate sections at the structure. Outbuilding rules. |
Enforcement in the early years is written as education-first. Inspectors are directed to look for measurable progress rather than a perfect yard. That is genuinely different from how defensible space citations have worked in some counties, and it is the reason panic spending right now is a mistake.
Does the rule reach your parcel?
Roughly 2 million structures are covered, in two buckets. Every property in a State Responsibility Area, where CAL FIRE handles wildfire protection. And every property mapped Very High Fire Hazard Severity Zone inside a city or county fire jurisdiction.
The second bucket has a catch worth reading twice. Inside local jurisdictions, only Very High parcels are reached by the state standard. If your map designation is High or Moderate, Sacramento's rule does not apply to you unless your city adopts it. Much of the Pasadena, Altadena, La Cañada Flintridge and Sierra Madre foothill belt is mapped Very High, so foothill homeowners should assume they are in. A flatland parcel in the same ZIP code often isn't. Look your own address up on the OSFM hazard severity maps before you buy anything.
The local-ordinance fight doesn't change your homework. Los Angeles has been the center of pushback — in January 2026 the City Council directed LAFD to draft a softer local version, with one councilmember estimating around $13,000 per property in some hillside neighborhoods. The state rules are a floor. Local agencies can go stricter and can stretch the Phase 2 clock, but a materially weaker local ordinance is expected to be preempted. Waiting for a carve-out is a bet against the statute.
The landscaping half, which is the cheap half
Bark mulch against the foundation, gorilla hair on the slope side, firewood stacked by the back door, juniper under a bedroom window, leaf litter in a side yard nobody walks through. That list is most of what an inspector flags and most of what actually burns houses down, and clearing it is a weekend or a $1,500 landscaping visit.
What can stay is broader than the rumor mill suggests: lawn and ground cover under three inches, spaced non-woody plants up to eighteen inches, noncombustible pots up to five gallons, and existing mature trees pruned to the clearances. Decomposed granite, pea gravel and stone are all compliant surfacing. Nobody is required to gravel their whole frontage.
One honest gap in the final rule text: artificial turf isn't addressed either way. Treatment will fall to inspector judgment under the general combustibility language. Anyone selling you a definitive answer on turf today is guessing.
The contractor half, which is where the money is
These are the items a landscaper will not touch and a general handyman will get wrong. They are also the items that overlap with work you may already be planning.
| Item | Trade | Typical 2026 CA cost |
|---|---|---|
| Noncombustible fence/gate span at the wall | Fencing or masonry | $400–$1,200 per attachment point |
| Ember-resistant vent replacement (ASTM E2886) | Roofing or general | $150–$600 per vent installed; $20–$80 in materials each |
| Under-eave enclosure / soffit boxing | Roofing or carpentry | $18–$40 per linear foot |
| Deck skirt and under-deck clearance | Carpentry | $1,200–$4,500 typical footprint |
| Gutter replacement with noncombustible covers | Roofing | $9–$22 per linear foot |
| Combustible shed removal or relocation | Demo / hauling | $600–$2,000 |
Vents deserve a paragraph of their own because they are the single most misquoted line on Zone 0 proposals. Chapter 7A of the California Building Code requires vents in wildfire-prone areas to resist ember and flame intrusion, protected by corrosion-resistant noncombustible mesh with 1/16 to 1/8 inch openings. The test standard is ASTM E2886, which subjects a vent assembly to both an ember shower and direct flame impingement. BrandGuard and Vulcan are the two names you will see most often on compliant products. A quote that says "upgrade vents to 1/8 inch screen" is not the same product as a quote that says "replace with ASTM E2886 listed vents," and the price gap between them is not a discount — it is a different job.
If a vent contractor is already on the roof, ask about rodent and bird exclusion at the same openings. Ember mesh and pest exclusion are the same hole and the same ladder, and California's rodent control crews are often the ones who find the soffit gaps in the first place.
Sequence it with work you were doing anyway
This is the part that separates a $6,000 outcome from an $18,900 one. Almost every expensive Zone 0 line item sits on a roof edge, a wall opening, or a deck — meaning it is nearly free to add to a job that already has scaffolding, a dumpster and a crew on site.
If your roof is within about five years of replacement, do the vents, the soffit boxing and the gutters during the reroof. Access and labor on a standalone vent visit commonly runs $100 to $250 more per vent than the same work folded into a tear-off. Start at California roofing, or go straight to Pasadena roofing, Riverside or San Diego if you are in those markets; the roofing hub covers material and Class A assembly questions.
Window work follows the same logic. Zone 0 requires vegetation-free space within two feet of windows, doors and vents, and Chapter 7A already governs the glazing itself in these zones — multi-pane with at least one tempered lite. If you are replacing windows anyway, the wildfire tempered glass spec and the Zone 0 clearance get evaluated in the same inspection. I went through the glazing performance data in wildfire-zone window protection, and none of it has changed with this rulemaking.
What to refuse
Three pitches are already circulating, and all three deserve a no.
"Compliance certification." No such certificate exists. Zone 0 is verified by a defensible space inspection from CAL FIRE or your local agency, and by the AB 38 documentation required at sale. Nobody sells you a passing grade.
"The deadline is next month." For existing homes, day-one duties are roof, gutters, dead branches and chimney clearance. Phase 1 is three years out. Phase 2 is three to five. Anyone compressing that into September urgency is selling on a clock they made up.
"We'll handle the whole yard." Ask which line items are Zone 0 requirements and which are recommendations. A full hardscape conversion is a fine project and it is not what the rule asks for. Get the required scope priced separately so you can see it.

Compare California contractor quotes →Where to start this fall
Do the day-one items in the next two weekends: roof and gutters cleared, dead branches cut, ten feet from the chimney, nothing growing under an eave. It costs almost nothing, it is required regardless, and it is the first thing any inspector looks at. Then walk your own five feet with a tape measure and write down only what needs a trade — a fence attachment, a vent count, a deck skirt, a soffit run. That list is your actual quote request.
Photograph everything as you go. Carriers already evaluate the first five feet at renewal under the Safer from Wildfires framework, and AB 38 will make you produce compliance documentation when you sell. The Sierra Madre homeowner ended up at $7,100: mulch and juniper out, two fence transition panels, nine ASTM E2886 vents scheduled into a reroof next spring, and the gutters done now. The $18,900 quote wasn't wrong about the work. It was wrong about the order.
If you are starting from scratch, California roofing, California windows and California pest control are the three pages that cover most of the contractor half, and the pest control hub and windows hub handle the terminology.
Frequently asked questions
Is Zone 0 enforceable in California right now?
The Board of Forestry approved the final regulations on August 19, 2026, and they went to the Office of Administrative Law for legal review in early September. Officials have pointed to roughly the end of September 2026 for the rules to become legally effective. Until OAL finishes, nothing is enforceable — but the substance is settled, so there's no useful reason to wait for paperwork before doing the day-one items.
Which California properties does Zone 0 cover?
Two categories, roughly 2 million structures. Every property in a State Responsibility Area, where CAL FIRE provides wildfire protection. And properties mapped Very High Fire Hazard Severity Zone inside a city or county fire jurisdiction. A parcel mapped High or Moderate inside a local jurisdiction isn't reached by the state rule unless the local agency extends it. Check your address against the OSFM hazard maps rather than assuming from your neighborhood's reputation.
Do I have to remove my wood fence?
No. The requirement is a noncombustible span where the fence or gate attaches to the structure, running the first five feet out from the wall. The rest of an existing wood fence stays, and like-for-like repairs remain legal. What's prohibited is new combustible fencing inside the five feet. In practice that's a steel or masonry transition panel — commonly $400 to $1,200 per attachment point installed — not a fence replacement.
Are all plants banned in the first five feet?
No, and this is where the early drafts scared people more than the final rule warrants. Lawn and ground cover under three inches is fine. Small, spaced non-woody plants up to eighteen inches are fine. Potted plants are fine in noncombustible pots up to five gallons. What goes is woody shrub material like juniper and hedging, anything growing under an eave or within two feet of a window, door or vent, and any newly planted tree inside the zone. Existing mature trees stay if pruned to the clearances.
Does Zone 0 compliance lower my homeowners insurance?
It can, through the Safer from Wildfires framework that the Department of Insurance requires admitted carriers to recognize. A clear first five feet is one of the listed property-level actions, alongside ember-resistant vents, a Class A roof and enclosed eaves. Carriers weight those differently and some apply them only at the community level, so the discount is real but modest on its own. For most foothill homeowners the bigger financial effect is renewal eligibility, not the percentage.
Should I do Zone 0 work during a roof replacement?
Yes, if the roof is within a few years of due. A reroof already has the crew on the eaves and the gutters off — exactly where under-eave clearance, gutter debris and ember-resistant vents live. Folding vents into a tear-off rather than a standalone visit typically saves $100 to $250 per vent in access and labor. Same logic for windows, since the two-foot clearance at openings and the Chapter 7A glazing spec get evaluated together.
What happens if I do nothing?
The early years emphasize education over penalties, and inspectors are told to look for measurable progress. But fines are available through existing defensible space enforcement authority, insurers already evaluate the first five feet at renewal, and AB 38 requires documented compliance at sale. Doing nothing mostly means doing it later, on someone else's schedule, at whatever contractors charge when everyone in your ZIP code needs the same work.
