When does Zone Zero go into effect? Fence and gate deadlines

What starts on day one, how the 3 and 5 year clocks count for fences and gates, and what has to happen before the state rule takes effect.

In this article (10)
Zone 0 deadlines for new and existing homesTwo lanes. New homes, meaning a building permit application submitted after the effective date: every Zone 0 requirement applies from the day the rule takes effect. Existing homes (14 CCR 1298.04(c); 1299.03(e)): on day 1, keep the roof and gutters clear, remove dead branches, keep branches 10 feet from chimney outlets and out from under eaves, and build no new wood or other combustible fence or gate within 5 feet. Within 3 years: remove combustible mulch, leaves and debris, firewood and anything that burns under decks and stairs, remove ladder fuels and keep branches 5 feet above the roof. Within 3 to 5 years: create the plant-free strips, bring other plants within the limits, give attached fences and gates a 5 foot noncombustible span, and make sheds in Zone 0 noncombustible or move them. In local Very High Fire Hazard Severity Zones the local fire agency sets 3 years or up to 5; in the State Responsibility Area it is 5 years or a CAL FIRE Director timeline of at least 3.

If you are replacing a fence near the house before then, build the first 5 feet in metal or masonry now so you do not build it twice. The Board adopted revised emergency regulations on November 5, 2026, and they keep the same phases (day one, 3 years, 3 to 5 years) with a few items moved; see Zone Zero update November 2026. The tables below follow the August 19 text unless marked. Current status is on is Zone Zero law in effect.

What starts on the effective date?

Under the August 19, 2026 text:

Item New homes Existing homes, local Very High zone (LRA) Existing homes, State Responsibility Area (SRA)
Roof and gutter debris, dead branches, branches near chimneys and under eaves Day one Day one Day one
No new combustible fence or gate within 5 ft Day one Day one Day one
Combustible mulch and debris, under-deck clearing, firewood, ladder fuels Day one 3 years 3 years
Plant-free buffer, plants, 5 ft noncombustible span on attached fences and gates, outbuildings Day one 3 years, or up to 5 on a local timeline 5 years, or a CAL FIRE Director timeline of at least 3

LRA means the Local Responsibility Area, where a city, county or district fights fires; SRA is where CAL FIRE does. A “new” home is one whose building permit application for initial construction is submitted after the effective date (14 CCR 1298.02(e)), so a house whose application went in the day before counts as existing.

The revised November 5 text moves branches under eaves from day one to 3 years, and says a later LRA final-phase deadline would need a local ordinance with a written finding, with the CAL FIRE Director setting the SRA schedule.

Rule text: 14 CCR 1298.04(c)(2) to (c)(4) for the LRA and 1299.03(e)(2) to (e)(4) for the SRA; the new-fence ban is 1298.04(b)(9)(B) and 1299.03(d)(9).

Does the new-fence ban wait 3 to 5 years too?

No. The ban on new combustible fences and gates within 5 feet starts on the effective date itself. If a fence within 5 feet of your house comes down after the rule starts and you rebuild it rather than repair it, the new section has to be metal, masonry or another noncombustible material.

The rule text is explicit: “After the effective date of this regulation, no new Combustible fences or gates (whether attached or parallel to the Occupied Structure) are permitted within five (5) feet of an Occupied Structure” (14 CCR 1298.04(b)(9)(B); the SRA version has the same ban and the same trigger). The 3 to 5 year window covers only fences already standing: the 5 foot noncombustible span on a fence or gate attached to the house or within 1 foot of it. Repairs to an existing wood fence may still use wood.

The Board’s own guidance muddies this, which may explain why some summaries put the ban on the later clock. Its narrative (page 23) says the rule prohibits “construction of new combustible fences within Zone 0,” but its summary table (page 37) lists the ban under the 3 to 5 year timeline, and the narrative puts the attached-fence span “within five years of the Zone 0 regulation adoption.” The rule text binds. It ties the ban to the effective date and gives LRA homes 3 years for the span unless the local agency sets up to 5. The revised November 5 text also lists new fences and gates within 5 feet at the effective date. Fence details are on Zone 0 fence requirements.

What would the deadlines be? Two hypothetical examples

If the rule took effect on December 1, 2026:

  • Roof, gutter and chimney-branch items: December 1, 2026.
  • New wood fence or gate within 5 ft of any house: not allowed from December 1, 2026.
  • Debris, mulch, firewood and ladder fuels on existing homes: December 1, 2029.
  • 5 ft noncombustible span on attached fences and gates, existing homes in a local Very High zone: December 1, 2029, or as late as December 1, 2031 if the local fire agency sets a longer timeline.
  • The same span, existing homes in the SRA: December 1, 2031, or earlier if the CAL FIRE Director sets a timeline, but no earlier than December 1, 2029.

If it took effect on June 1, 2027, move every date by six months: LRA fences by June 1, 2030 (or up to June 1, 2032), SRA fences by June 1, 2032 (no earlier than June 1, 2030).

What has to happen before Zone Zero takes effect?

Four steps:

  1. The Board adopts the rule. It did, 8 to 0, on August 19, 2026, and adopted a revised version on November 5, 2026. AB 1455 lets the Board readopt an emergency regulation that is “the same as or substantially equivalent to” one it adopted before (Government Code 51182.4(c)).
  2. The Board files it with OAL. The August filing was withdrawn on September 8, 2026, before OAL ruled. The Board’s notice anticipates submitting the revised package on or after November 13, 2026.
  3. OAL reviews it. OAL posts a notice of the filing on its website, which opens a five calendar day public comment period. It then has 10 calendar days to approve or disapprove.
  4. OAL approves and files it with the Secretary of State. Per OAL, an emergency regulation “usually becomes effective when filed with the Secretary of State.” That filing date is the effective date every deadline counts from.

Most emergency regulations lapse after 180 days unless readopted. Zone 0 is an exception: AB 1455 says these regulations “shall remain in effect until revised” by the Board (51182.4(d)).

How soon could the rule take effect?

In late October 2026 Board staff put the soonest effective date at the very end of November or early December. If OAL approves within its 10 day window and files the rule promptly, the start date would come about two weeks after a filing. OAL lists an approval with its date on its recent actions list, and that date starts every clock on this page.

Does enforcement start on the same day?

Only for the day-one items. Everything else can be enforced only after its own deadline passes, which for the attached-fence span on existing homes is 3 to 5 years after the effective date. A new wood fence built within 5 feet after the start date would be out of compliance at once.

The Board’s guidance says Zone 0 “will be enforced like other defensible space requirements,” by local fire authorities in the LRA and CAL FIRE’s defensible space inspectors in the SRA, whose inspections “aim to confirm good-faith progress toward compliance.” In the SRA, CAL FIRE also needs a written funding finding from the State Fire Marshal before it changes its inspections for the zone (PRC 4291(h)). More on enforcement is on Zone Zero law in California.

Which local Zone 0 timelines are already running?

San Diego and Berkeley have their own rules in force, and AB 1455 lets a local agency be “more stringent” than the Board (Government Code 51182(f)).

  • San Diego: new structures since February 28, 2026; enforcement on existing homes from February 28, 2027; a target of February 28, 2029 for full compliance, fences and gates included. See San Diego Zone Zero fence rules.
  • Berkeley: since January 1, 2026 in the Grizzly Peak and Panoramic Hill areas, including a ban on new or replacement combustible fence sections within 5 feet. See Berkeley’s EMBER Zone 0 ordinance.

Why do some sites give a 2027 or 2029 deadline?

Usually because they borrowed San Diego’s local dates or counted from the Board’s August 19, 2026 vote. Neither is a state deadline. The state clocks start on the OAL effective date. Other common claims, including that Zone 0 applies when you sell a house, are covered on is Zone Zero a law. The day-one roof, gutter and branch work is worth doing now; the order of work is in how to comply with Zone Zero.

Questions people ask

What is the Zone Zero deadline for existing homes?

No deadline is running yet, because the rule has not taken effect. Under the text the Board adopted on August 19, 2026, existing homes in local Very High zones would get 3 years from the effective date for fences, gates and the plant-free buffer, or up to 5 on a local timeline. Existing homes in the State Responsibility Area would get 5 years, or a CAL FIRE Director timeline of at least 3. A new combustible fence or gate within 5 feet would not be allowed from the effective date itself. The revised text the Board adopted on November 5, 2026 keeps 3 to 5 years for existing fences and gates; a later LRA deadline would need a local ordinance with a written finding.

When will Zone Zero be enforced?

Not before the rule takes effect. Day-one items, including the ban on new combustible fences within 5 feet, apply from the effective date; the rest only after their own deadlines pass. Local fire agencies enforce it in the Local Responsibility Area and CAL FIRE in the State Responsibility Area. In the SRA, CAL FIRE also needs a written funding finding from the State Fire Marshal before it changes its inspections for the zone (PRC 4291(h)).

When was the Zone Zero vote?

The Board of Forestry voted 8 to 0 to adopt the Zone 0 regulations on August 19, 2026. The vote did not make the rule effective. The Board filed it with OAL on August 28, 2026 and withdrew it on September 8, 2026, before OAL ruled. Sonoma Valley Fire District reports the Board adopted revised emergency regulations on November 5, 2026.
