Firewood storage in California's Zone 0: the free fix to make this weekend

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

Firewood costs nothing to fix: you pick the wood up and put it down somewhere else. Most other Zone 0 items cost money, from fences and gates to hardscape and hardware. Here is what the adopted rule says, what the in-force local rules require, and where the pile can go.

One sentence covers your woodpile

The Board of Forestry's Zone 0 regulation deals with firewood in one sentence. It sits in the Local Responsibility Area text at proposed 14 CCR §1298.04(b)(4), and the State Responsibility Area track carries the same prohibition at §1299.03(d)(4):

No firewood shall be stored in Zone 0.

Board of Forestry Zone 0 rule text, proposed 14 CCR §1298.04(b)(4) and §1299.03(d)(4), unchanged from the July 2026 draft through the August 19, 2026 package

Zone 0 is the ember-resistant zone: the first five feet measured out from the exterior wall, roof, attached deck, stairs, or pergola, or to the property line if that comes first (see what Zone 0 actually is). The August package narrowed the definition behind that measurement, so an attached deck, stairs, or pergola counts as part of the structure even when it is noncombustible, and only noncombustible patios are excluded. Firewood is the only stored-item category the rule names outright in its Zone 0 prohibitions.

The regulation is adopted, not yet in effect, so no compliance clock is running. Once effective, it applies in State Responsibility Areas (SRAs) and Very High Fire Hazard Severity Zones in Local Responsibility Areas (LRAs): about 2.12 million structures, 17 percent of the state's total, per the Board of Forestry and CAL FIRE. Check whether your address is covered. Two things to keep in mind about the text itself. The LRA and SRA tracks run in parallel but are not word for word the same: the SRA version uses "Building or Structure" where the LRA version uses "Occupied Structure," and the fence provisions differ in substance between them. And the August 19, 2026 package in the board binder is the pre-meeting deliberative draft, so amendments made from the floor would not appear in it, and no certified "as adopted" text has been published yet.

On timing, firewood sits in the three-year tier for existing homes:

PHASE 1 (Implemented within the first 3 years): Includes removing combustible items such as firewood, dead leaves and branches, mulch, and wood chips within 5 feet of the structure.

Board of Forestry, July 2026 draft Zone 0 summary

One August change reshuffled that grouping, though not for firewood. Roof and gutter debris, provision (b)(2), moved to immediate compliance for existing structures on the effective date, so the three-year tier now reads "(b)(1) and (b)(3)-(4)" rather than "(b)(1)-(4)". Firewood is (b)(4) and stays in the three-year group. New construction complies on the effective date. No calendar dates exist yet: every deadline runs from an effective date that has not been set. Fences sit in the later phase with a longer runway; the timeline and enforcement guide covers both.

Why this is the start-here category

Zone 0 is about embers: most homes lost in wildfires ignite when wind-driven embers land on or near the house, and combustible material in the first five feet gives them something to catch. A stacked cord of dry wood against the wall is exactly that. Firewood is the first example the Board's own Phase 1 description reaches for. And unlike a fence transition or a mulch-to-gravel swap, the whole fix is deciding where the wood lives and keeping it there.

Berkeley and San Diego already regulate stored combustibles

Statewide, the rule is approved but not yet effective. Locally, these are live obligations, and both in-force rule sets go further.

Berkeley. The EMBER ordinance took effect January 1, 2026 in the Grizzly Peak and Panoramic hillside mitigation zones. Within five horizontal feet of any structure (including outbuildings, attached decks, and stairs), combustible material is banned, with a list worth reading in full:

Combustible materials include but are not limited to vegetation, climbing vines, combustible boards, timbers, firewood, debris, synthetic lawn, wood mulch products, combustible fencing and gates (e.g.: wood/vinyl), playsets, plastic trash and recycle cans, trellises, pergolas, shade coverings, planters, attached window boxes, privacy walls, boats, RVs, and other material that could be ignited by embers, radiant heat, or direct flame.

City of Berkeley fire code amendments (Section 4907.6), adopted ordinance text, April 15, 2025 council packet

In Zone 1, which runs 5 to 30 feet out, the ordinance adds that "Storage of firewood, lumber, or other Combustible Material is not permitted"; exposed piles must leave Zone 1 unless completely covered in fire-resistant material. Uncovered firewood therefore ends up beyond 30 feet, where Zone 2 requires 10 feet of bare-soil clearance around exposed piles. Enforcement began with a grace period, with inspections reported ramping up through 2026; confirm practice with Berkeley Fire. Other jurisdictions are in our local ordinance tracker.

San Diego. The city's Zone 0 guidelines (Rev. 4/22/2026, implementing SDMC §512.0604) apply in Very High Fire Hazard Severity Zones inside city limits only (details in our San Diego guide). Section 4.8 prohibits within five feet of a structure: long-term storage of flammable or combustible materials; garbage and recycling containers (with a collection-day exception, and moved into the garage on Red Flag Warning Days); and boats, RVs, and trailers. On attached decks, firewood and combustible storage are prohibited within five feet of exterior walls, and under-deck areas must stay free of combustible storage.

Timing: the rules applied to new structures on February 28, 2026 and reach existing structures beginning February 28, 2027, when "Relocation of firewood piles, trash bins, and other stored combustible materials" becomes a Year 1 maintenance item; full compliance is targeted by February 28, 2029.

Where the woodpile can go

Every rule set we track agrees on the first five feet. They diverge beyond it.

Five feet is the line in the state regulation and in San Diego; 30 feet is where Berkeley and the IBHS standard land for uncovered wood. If you have the space, use the bigger number and every row of this table gets easier to meet.

Bins, boats, and RVs: what the statewide rule does not say

You may have seen claims that the state is about to ban trash cans and RVs. The rule text does not support that: a full-text search of the 26-page July 2026 draft found no Zone 0 prohibition naming bins, boats, RVs, trailers, vehicles, or patio furniture, and the August package did not add one. Such items are reachable only through the general definition of "Combustible" and the rule that areas under decks, balconies, pergolas, and stairs stay free of combustible items. The name-the-item lists live in the local rules and the voluntary standard:

Metal racks and enclosures: useful, not magic

The honest part first: nothing on this page requires a purchase. Relocation is the compliance path everywhere; a rack or enclosure is a convenience that makes the new location stick.

If you do buy, the materials logic is familiar: aluminum and steel are among the materials that pass ASTM E136, the noncombustibility test behind the regulation's definition of "Noncombustible" (see our materials guide). Placement matters more than product. The firewood sentence carries no cover-or-enclose exception, so once the rule is in effect a box in the first five feet will not make firewood storage there permitted. A structure in Zone 0 would also run into the outbuilding provision, which allows outbuildings there only if built entirely of noncombustible materials (see sheds and outbuildings). The rack's job is to live outside the five feet.

One claim we could not verify, so we will not make it: no primary source allows trash bins to stay inside Zone 0 because they sit in a metal enclosure. The verified paths are relocation-based. Berkeley bans "plastic trash and recycle cans" and does not say whether metal cans pass. Ask Berkeley Fire before spending money on that theory.

The insurance credit for clearing the five feet

Separate from defensible space law, California's "Safer from Wildfires" insurance regulation (10 CCR §2644.9, operative October 14, 2022) requires insurers that price on wildfire risk to offer rating credits for enumerated mitigation measures. One is this exact task:

Clearing of vegetation, debris, mulch, stored combustible materials, and any and all movable combustible objects, from the area within five (5) feet of the Building Being Evaluated

10 CCR §2644.9(d)(1)(B)1.b

Two clarifications, because this is where competitors overpromise: the regulation binds insurers, not homeowners, and it is a rating rule rather than an underwriting mandate. It promises no particular savings and guarantees no coverage. It does mean this free task maps to a line item on your carrier's mitigation form. Document the work with dated photos, as our documentation guide explains.

What this means for you

• Move the wood first. Five feet out at minimum, measured from the wall, attached deck, stairs, or pergola. With space, 30 feet covers Berkeley's rules and the IBHS standard for uncovered piles.
• Check under the deck. Every rule set on this page wants combustible storage out from under decks and stairs.
• Don't rely on a tarp. IBHS bars fire-retardant tarps outright, and the state rule's Zone 0 firewood ban has no cover exception.
• In Berkeley's hillside zones or San Diego's Very High zones? Treat these lists as current obligations and confirm details with your fire department.
• Photograph the result. The cleared five feet is a mandatory credit item under the insurance regulation. Dated before-and-after photos cost nothing.
• Then keep going. Firewood is one line on the full Zone 0 checklist; mulch, debris, and other stored combustibles follow the same five-foot logic.
