California Zone Zero enforcement: when a fence or gate can be cited

California Zone Zero enforcement starts the day the state rule takes effect. The agencies that inspect defensible space now (CAL FIRE in the State Responsibility Area, your city or county fire agency in local Very High zones) enforce it: a new wood fence within 5 feet of the house can be cited from day one, and an existing fence or gate that touches the house only after its 3 to 5 year deadline passes.

Today’s inspections check the 100 foot defensible space rules. Rule status is on is Zone Zero law in effect.

When could a fence or gate be cited?

Not until the rule takes effect and the relevant deadline passes. The attached-fence span on an existing home is due 3 years after the effective date in local areas, or up to 5 on the local agency’s timeline (14 CCR 1298.04(c)(4)), and 5 years in the SRA, or not less than 3 on the CAL FIRE Director’s timeline (14 CCR 1299.03(e)(4)). The ban on new combustible fences within 5 feet runs from the effective date. Worked dates are on when Zone Zero takes effect.

Some city rules are already enforced. Berkeley’s Zone 0 code took effect January 1, 2026, and by late September 2026 the city had done about 600 to 700 inspections with no citations issued. Details are on Berkeley’s ember zone ordinance.

Who enforces Zone Zero?

The fire agencies that inspect defensible space now. The Board’s guidance says: “The Board of Forestry and Fire Protection is not responsible for enforcement.” It expects Zone 0 to be “enforced like other defensible space requirements,” which splits by who protects the land:

Am I in Zone Zero shows how to find your row.

How does a defensible space inspection work today?

In the SRA, CAL FIRE leaves a written notice, form LE-100a. The 3/17 version opens: “A fire department representative has inspected your property for fire hazards. You are hereby notified to correct the violation(s) indicated below. Failure to correct these violations may result in a citation and fine.” Most checklist items cite PRC 4291 or 14 CCR 1299.03, from branches within 10 feet of a chimney to annual grass over 4 inches.

Local agencies run their own versions with their own deadlines. Two examples:

• Sonoma County Fire District (SRA form, 2022). Owners get 30 days to correct violations (the form says business days on the front and calendar days on the back). If they are not fixed by reinspection, “an Administrative Citation will be issued” with a $100 fine under Sonoma County Code 1.7.6, plus inspection costs, attorney’s fees and abatement costs, secured by a lien.
• LAFD brush clearance (City of Los Angeles, 2026). Clearance was due May 1, 2026. Fees, “subject to change,” were $31 after a failed first inspection and another $758 after a failed second. If the lot is still out of compliance, it “Shall Be Cleared by City Contractors and Billed to The Property Owner,” with a $1,740 administrative fee on top of the contractor’s bid, and a 200% penalty for late payment. More on LA is on Los Angeles Zone Zero.

None of these forms has a Zone 0 line yet.

What penalties apply under state law?

The Zone 0 rule text itself sets standards and deadlines (14 CCR 1298.04(c) and 1299.03(e)) but no fines. Penalties come from the statutes the rule sits under, which already apply to defensible space violations:

AB 1455 also protects owners who follow a local alternative: an owner in compliance with alternative practices adopted by local ordinance “shall not be deemed to have violated” Section 51182 for penalty purposes (Government Code 51182(f)(2)).

What does the law say about enforcing Zone 0 specifically?

Three provisions limit how fast Zone 0 enforcement can start, beyond the rule’s own 3 to 5 year clocks for existing homes:

1. Funding finding in the SRA. CAL FIRE “shall not change defensible space inspection practices and forms or enforcement” for the ember-resistant zone until the State Fire Marshal posts a written finding that the Legislature has appropriated enough money (PRC 4291(h)).
2. Notice before penalties in the SRA. The State Fire Marshal must “make reasonable efforts to provide notice to affected residents” of the Zone 0 requirements “before the imposition of penalties” (PRC 4291(f)(2)).
3. Notice before penalties in local areas. Each local agency must “make reasonable efforts to provide notice to affected residents” of the Zone 0 requirements “before the imposition of penalties” (Government Code 51186(b)(1), as amended by SB 504 in 2024). AB 1455 rewrote 51182 in 2025 but left 51186 alone, so this duty still stands.

The Board’s materials push the same direction. The guidance says SRA inspectors will help owners “prioritize actions over three years,” that inspections “aim to confirm good-faith progress toward compliance,” and that “the goal is not to penalize property owners.” Its tips for inspectors include “penalties are not a place to start a conversation.” The July 2026 staff memo says good-faith progress was put in the guidance “rather than within the regulations themselves,” so it is not a defense written into the rule.

What is not decided yet?

• The effective date, which starts every deadline. The Board process is on Board of Forestry Zone Zero regulations.
• Whether and when the State Fire Marshal makes the PRC 4291(h) funding finding.
• What the revised CAL FIRE inspection form will list for Zone 0, and how inspectors will check that a fence is noncombustible (the rule ties that to the ASTM E136 test but sets no paperwork procedure).
• The 3 to 5 year timelines each local fire agency and the CAL FIRE Director will choose.

What should I do before an inspector comes?

1. Pass the inspection you already face: roof and gutters clear, dead branches cut, branches 10 feet from the chimney. Those items are law now, and the rule makes them day-one Zone 0 items for existing homes too, along with keeping live branches out from under the eaves (14 CCR 1298.04(c)(2); 1299.03(e)(2)).
2. Keep any notice you receive. It names the inspecting agency and the reinspection date, and that agency is the one that enforces Zone 0 at your address.
3. Ask the inspector two questions: has the agency set a Zone 0 timeline, and what will it accept as proof that a fence or gate is noncombustible.
4. List each fence or gate that touches the house or comes within 1 foot of it. Each needs a 5 foot noncombustible span; options are on Zone 0 gate requirements.
