What changed in August 2026
On 19–20 August 2026, the California Board of Forestry and Fire Protection approved Zone 0 regulations for the first five feet around homes and structures. Coverage (ABC10, Patch, the San Francisco Chronicle, Insurance Journal) puts the stock at about 1.75 to 2 million homes in State Responsibility Areas and Very High Fire Hazard Severity Zones inside Local Responsibility Areas.
“Research, fire science, and experience show that this is the most critical area for protecting your home, your neighbor’s homes and the community around you.” Board explainer, as quoted by ABC10, 20 August 2026
The package is the ember-resistant layer on top of existing defensible-space zones. It is not a statewide wipe of every yard. Local jurisdictions can adopt alternative approaches with substantially similar practical effect.
Two clocks, not one punch list
- New construction — described as applying on adoption; some reports point to September.
- Existing homes, Phase 1 (within 3 years) — combustible items in the five-foot band (firewood, wood chips, combustible mulch, dead leaves and branches), gutters, dead or dying plants, tree maintenance.
- Existing homes, Phase 2 (within 5 years) — local timelines for under-eave vegetation other than trees, combustible gates, sheds, and fencing adjustments.
Those clocks start when the regulation is effective, not when you read this page. This desk dates the public record. It does not start your clock and does not inspect your lot.
Where the sources disagree — and stay in the paper
Board materials describe a five-foot Zone 0. Insurance Journal reported the strictest vegetation-free band was reduced to a minimum of one foot (or to the eaves, whichever is farther), with some plants and maintained trees allowed in the rest of Zone 0. Existing trees can remain if maintained; new trees in the zone are described as not allowed. Existing combustible fences are treated differently from new combustible fences in Board staff memos. This briefing does not collapse that into one official table.
Not legal, insurance, or CAL FIRE advice. Not a certificate that the property complies.
Preview — not the paid paper
Zone 0 work-list — this address
Name the address and what sits in the first five feet. This preview is a working assumption against the August 2026 public record. It is not an inspection and not a certificate.
This paper will lock the named address, the checked items, and the cited sources as of the issue date.
Worked example (free)
A 1,200 sq ft ranch. Wood-chip mulch to the siding. Combustible gate on the house. Gutters full of needles. One existing oak with limbs near the roof. No firewood pile.
- Phase 1 bucket: pull combustible mulch out of the five-foot band; clean gutters; maintain the existing tree (lift / clearance). That is the example, not a bid.
- Phase 2 bucket: combustible gate on the house sits in the later local-timeline bucket in the public coverage — confirm against the text that is in force for this jurisdiction.
The free example is how the phases split. The paid paper is the dated lock of your address and the sources retrieved that day.
Questions
Is this an official CAL FIRE or Board inspection? No. It is a briefing plus an optional dated paper. Enforcement sits with the state or the local authority, depending on the jurisdiction.
Does $29 clear my insurance or HOA? No. The paper is a third-party lock of the public record as of a date. The carrier, HOA, or inspector still decides.
What did the Board approve? Ember-resistant rules for Zone 0, the first five feet, after AB 3074 (2020), SB 504 (2024), AB 1455 (2025), and Executive Order N-18-25. See the citations.
