Malibu's fires are the case study for the first five feet
The Woolsey Fire crossed the Santa Monica Mountains in a single wind-driven run on November 9, 2018, and burned to the sand. An analysis of aerial imagery and property records by the Los Angeles Times and Zillow found at least 670 structures destroyed inside Malibu city limits, including more than 400 single-family homes.
Most of those homes were not touched by a wall of flame. Wind-blown embers landed in mulch beds, wood fences, and dry plants pressed against siding. The first five feet decided which houses stood the next morning.
Six years later the December 2024 Franklin Fire repeated the lesson on a smaller scale: 4,037 acres through Malibu Canyon and Serra Retreat, 20 structures destroyed, and Pepperdine students sheltering in place. The first five feet is where that pattern can be interrupted.

As of September 19, 2026 there is no statewide Zone 0 regulation in force in California. Malibu's own rule, Chapter 17.53, is in force locally and leads this site. Existing state defensible-space law still applies.
Malibu's own rule, plus existing state law
MMC Ch. 17.53, effective August 12, 2020, on projects requiring permits: hedges and flammable fences or walls are prohibited within 5 feet of a building, and mulch there must be nonflammable. State law (PRC §4291, Gov. Code §51182) also requires roofs and gutters clear of leaves and needles.
Statewide Zone 0
The Board of Forestry approved a draft on August 19, 2026. OAL file 2026-0828-03E is listed as withdrawn (September 8, 2026). There is no statewide effective date and no statewide phase-in clock.
No retrofit deadline found
Chapter 17.53 applies to projects requiring permits. Exemptions are in MMC 17.53.030(B). We did not find a retrofit deadline for existing structures. Confirm with the City of Malibu.
Harden the first five feet
Clear combustibles, use nonflammable ground cover, and consider ember-resistant vents. The county's 100-foot defensible-space radius is a recommendation, and Malibu's free city assessments flag vents first.
LA County Fire is the fire authority. The City of Malibu has its own rule.
Malibu contracts its fire protection to the Los Angeles County Fire Department, whose Defensible Space program lists Malibu among the cities it covers. That program lists chimney clearance as required and a 100-foot defensible-space radius as a recommendation. It does not use Zone 0 as a requirement.
The local rule is in the city's own code: Malibu Municipal Code Chapter 17.53, fire-resistant landscaping, effective August 12, 2020 (source: City of Malibu, Fire-Resistant Landscaping). The city also runs Fire Safety Liaisons, free home wildfire hardening assessments booked through City Hall, and a free hazard tree removal program.
Quick answers for Malibu homeowners
Is Zone 0 required in Malibu?
Malibu has its own rule for the first five feet, and it is in force. Malibu Municipal Code Chapter 17.53 (fire-resistant landscaping) took effect August 12, 2020. On projects that require permits, hedges and flammable fences or walls are prohibited within 5 feet of a building, and mulch in the first 5 feet must be nonflammable, such as gravel or decomposed granite. Shredded bark, pine needles, artificial turf, wood chips, and shredded rubber are prohibited. Exemptions are listed in MMC 17.53.030(B), and we did not find a retrofit deadline for existing structures. Confirm what applies to your project with the City of Malibu and Los Angeles County Fire.
Is Zone 0 a statewide law in California?
As of September 19, 2026 there is no statewide Zone 0 regulation in force in California. The Board of Forestry approved a final draft on August 19, 2026, but the state's own record lists OAL file 2026-0828-03E as withdrawn on September 8, 2026. Existing defensible-space law (PRC section 4291 and Government Code section 51182) still applies, including keeping roofs and gutters clear of leaves and needles.
Is there a deadline for existing Malibu homes?
We did not find a retrofit deadline for existing structures in Malibu's Chapter 17.53, and there is no statewide deadline because no statewide Zone 0 regulation is in force. The statewide draft is Proposed — not in force, with no effective date. Clearing and hardening the first five feet is Recommended now as prevention.
Do Woolsey rebuilds or new construction have to meet a Zone 0 rule?
No statewide Zone 0 rule is in force. Malibu's Chapter 17.53 applies to projects requiring permits after August 12, 2020, subject to the exemptions in MMC 17.53.030(B), so your permit is the place to ask the City of Malibu what applies to your lot.
Who is the fire authority in Malibu?
The Los Angeles County Fire Department. The county's Defensible Space program lists Malibu among the cities it covers. That program lists chimney clearance as required and a 100-foot defensible-space radius as a recommendation; it does not use Zone 0 as a requirement. The City of Malibu adds its own layer: Fire Safety Liaisons, free home wildfire hardening assessments, and a hazard tree removal program.
Is this the same as brush clearance?
No. Existing defensible-space rules cover a wider band around your home. Malibu's Chapter 17.53 speaks to the first five feet on projects requiring permits: hedges, fences and walls, and mulch. Even where no rule applies to your project, clearing that five feet is the most effective prevention step a homeowner can take.
