Zone Zero Deadlines for Hidden Hills

Final Zone Zero regulations are expected late 2026. The ember-resistant zone rules for new fences and rebuilds apply immediately at adoption. Phase 1 clearing is estimated 2027-2028, and Phase 2 replacement runs on a deadline set by the Los Angeles County Fire Department, up to 5 years out.

Zone Zero Hidden Hills / Deadlines

The Timeline

Zone 0 arrives in phases, not all at once

Read this top to bottom as best current estimates, anchored to the April 17, 2026 Board of Forestry draft. Bold items are locked by statute; the rest can move before final adoption.

  1. Now, mid 2026

    The April 17, 2026 draft is in its final comment and revision cycle. Nothing is enforceable yet. This is the planning window, and the cheapest time to schedule work.

  2. Late 2026 (expected): final adoption

    Immediate on adoption: no new combustible fences or gates within 5 feet of a structure, and full Zone Zero compliance for rebuilds and new construction. No grace period.

  3. Est. 2027-2028: Phase 1

    Clear combustible material from the 0-5 ft zone around existing structures: mulch, dead vegetation, firewood, hay, shavings, stored items.

  4. Up to 5 years after adoption: Phase 2

    Replace built combustibles in the zone: fences, gates, attached combustible structures. The Los Angeles County Fire Department sets this deadline for Hidden Hills.

Your jurisdiction sets the specifics
Hidden Hills is enforced by the Los Angeles County Fire Department, not by a city fire department and not directly by Sacramento.
County defensible space inspections already run annually from May 1. Zone Zero checks will ride on that existing cycle.
Where county practice differs from the state default timeline, the county's dates are the ones that bind your parcel.

Common Questions

Deadline questions, answered

What is the very first deadline I could face?

The moment final regulations adopt, expected late 2026, two rules apply immediately: no new combustible fences within 5 feet of a structure, and full Zone Zero compliance for rebuilds and new construction. Everything else phases in afterward.

Who sets the Phase 2 deadline for Hidden Hills?

The Los Angeles County Fire Department, as the city's fire authority. State law allows the local jurisdiction up to 5 years after adoption for the built-item replacement phase.

Are these dates final?

No. Phase 1 at 2027-2028 is an estimate based on the April 17, 2026 Board of Forestry draft, and every date here can move before final adoption. That is exactly why this page separates what is immediate from what is estimated.
