Are There Zone 0 Deadlines in Hidden Hills?
Zone Zero Hidden Hills / Deadlines
What is in force now, what is proposed, what is recommended
Three labels, used the same way on every page: Required now · Proposed — not in force · Recommended now. Nothing on this page carries a statewide date, because none exists.
-
Required now
Existing state law (PRC §4291 and Gov. Code §51182): keep roofs and gutters clear of leaves and needles, and remove branches within 10 feet of a chimney outlet. We have not identified a local Zone 0 ordinance for Hidden Hills.
-
August 19, 2026: draft approved
Proposed — not in force. The Board of Forestry approved a final draft of the statewide Zone 0 regulation. Approval of a draft is not adoption.
-
September 8, 2026: filing withdrawn
Proposed — not in force. OAL file 2026-0828-03E is listed as withdrawn. There is no statewide effective date and no statewide phase-in clock.
-
Recommended now
Clear combustible material from the first five feet of the house and the barn, and fit ember-resistant vents. This is effective prevention whether or not a Zone 0 rule ever applies to your parcel.
