Your jurisdiction sets the specifics. For Brentwood, that jurisdiction is the City of Los Angeles, acting through LAFD. The state timeline above is the floor; the city may publish stricter or earlier local requirements, and its annual brush clearance cycle (inspections from May) already applies today regardless of Zone 0 timing.
Deadline Questions

Zone 0 deadline questions from Brentwood

What is the very first deadline I need to care about?

Adoption itself, expected late 2026. The moment final regulations adopt, new combustible fences in Zone 0 are barred and rebuilds must comply from day one. Phase 1 clearing for existing homes follows, estimated 2027-2028.

Who sets the Phase 2 deadline for Brentwood?

The City of Los Angeles, as the local Authority Having Jurisdiction, working through LAFD. State law allows up to 5 years after adoption for replacing built items like fences and gates. The city's specific schedule has not been published yet.

I am remodeling now. Should I wait for the final rules?

No. Anything you build today that would violate Zone 0 becomes a retrofit later. Building the first five feet to the draft standard now, noncombustible ground cover and a metal fence connection, is cheaper than doing the work twice.

Will LAFD really enforce this?

LAFD already runs one of the most systematic defensible-space programs in the state: its Brush Clearance Unit inspects every Very High FHSZ parcel annually, including Brentwood's canyons. Zone Zero adds requirements to a program that already has inspectors, records, and consequences. Enforcement starts education-first.
