Zone 0 Fire Safety in Southern California: The 2026 Homeowner’s Guide

November 3, 2026

Robert on a job, or a clean, cleared Zone 0 area around a Southern California home.

If you own a home anywhere from San Diego up to Ventura County, Zone 0 has probably landed on your radar this year. Maybe your insurance company mentioned it. Maybe your fire department did. Or maybe after the January 2025 fires in Los Angeles, you just started looking at the five feet around your house differently.

This is the complete rundown for Southern California homeowners: what Zone 0 is, where the rules actually stand right now, what has to go, what you can keep, and how to get ahead of it without overspending.

What is Zone 0 (or “Zone Zero”)?

Zone 0, also written Zone Zero, is the first five feet around your home. The state calls it the “ember-resistant zone.” It’s measured out from your walls, your deck, and anything attached to the house.

It matters because most homes that burn in a wildfire aren’t hit by a wall of flames. They’re lit by embers. In Southern California, Santa Ana winds can carry embers a long way ahead of a fire. They land in dry leaves, bark mulch, or a woodpile against the house, and that’s what starts it.

Zone 0 sits inside California’s bigger defensible space system:

Zone 0: 0 to 5 feet, the ember-resistant zone
Zone 1: 5 to 30 feet
Zone 2: 30 to 100 feet

For the full explainer, see our guide: What is Zone 0?

Where the Zone 0 rules stand right now

Here’s the short version, because there’s a lot of outdated information floating around:

August 19, 2026: California’s Board of Forestry approved the final draft of the statewide Zone 0 rules, 8 to 0.
August 28: The Board sent the rules to the state’s Office of Administrative Law for final review.
September 8: The Board pulled them back from that review to make technical fixes.

You can read more about the rules and status here: https://www.fire.ca.gov/dspace

So right now, the statewide Zone 0 rules are not in effect, and there’s no effective date. The Board has said the withdrawal is procedural, and another public comment period is likely before the rules come back.

The big exception is San Diego. The City of San Diego already has its own Zone 0 rules, with its own timeline. More on that below.

Nothing below is a requirement today, statewide. But the rules are coming, and the approved version gives a very clear picture of what they’ll look like.

Does Zone 0 apply to your Southern California home?

Once the statewide rules take effect, they apply to homes in:

State Responsibility Areas, mostly unincorporated and wildland areas where CAL FIRE is responsible.
Very High Fire Hazard Severity Zones inside cities and other local areas.

You can look up your address on CAL FIRE’s Fire Hazard Severity Zone map, or we can check it for you during a free assessment. A lot of Southern California falls into these zones, including hillside and canyon neighborhoods in all four of our counties.

Zone 0 in your county

Los Angeles County. From the South Bay to Malibu and up into the foothills, thousands of homes sit along canyons and hillsides. After the 2025 Palisades and Eaton fires, Zone 0 became a priority for a lot of LA homeowners. Robert spent more than 28 years with the Torrance Fire Department, so LA County is home turf.

Orange County. Many neighborhoods back right onto open space and canyons, from the coast to the Santa Ana Mountains. HOAs here often have their own standards on top of state rules. Zone 0 in Orange County

San Diego County. The City of San Diego is ahead of the state, with its own Zone 0 rules already adopted. If you’re in the city, your timeline is set locally, not by the statewide rule. Zone 0 in San Diego County

Ventura County. From Ojai to the Conejo Valley, Ventura County has been through some of the state’s most destructive recent fires, and lots of homes sit near brush-covered hillsides and orchards. Zone 0 in Ventura County

The two parts of Zone 0

The approved rules split the five feet into two areas:

The safety zone, right against your house. This is a plant-free strip at least a foot wide, and it widens to match your eaves. If your eaves stick out two feet, the safety zone is two feet.
The low-combustibility zone, the rest of the five feet. Some plants can stay here, as long as they’re healthy, spaced out, and nothing burnable is on the ground.

Your Zone 0 checklist: what has to go

Under the approved rules:

Bark mulch and wood chips. Swap them for gravel, rock, or decomposed granite.
Dead leaves, needles, and dead or dying plants.
Firewood and anything burnable stored against the house.
Leaves and debris on your roof and in your gutters.
Plants within two feet of windows, doors, and vents, and within five feet of an attached deck.

What you can keep

This part surprises people. Zone 0 doesn’t mean a bare dirt moat around your house.

Small, non-woody plants, like bulbs, poppies, petunias, and succulents, in spaced-out groupings.
Low ground covers, like creeping thyme or beach strawberry.
A maintained lawn.
Potted plants, in containers that won’t burn and that you can easily move.
Your trees, if they’re maintained. Keep branches 10 feet from the chimney and 5 feet above the roof, keep them out from under the eaves, and trim off the lower branches that could carry fire up into the tree.

Fences, gates, and sheds

Wood fences attached to your house need a five-foot noncombustible section where they meet the house. A metal gate is a common fix. You don’t have to replace the whole fence. We wrote a full post on this: Zone 0 fence rules.
Sheds inside Zone 0 need noncombustible roofs and walls.

When it all kicks in

Once the statewide rules take effect:

New homes have to comply right away.
Existing homes get about five years, in two phases. The first phase, within about three years, covers the basics: clearing out mulch, firewood, and dead plants, cleaning gutters, and trimming trees. The second phase, within five years, covers the bigger stuff: the safety zone under the eaves, gates, fences, and sheds.

The state has said it’ll focus on education first, not penalties. But there’s still a good reason not to wait.

What about your insurance?

News coverage of Zone 0 has reported that insurance companies are looking at the five feet around the home when they size up wildfire risk. Plenty of Southern California homeowners are already getting non-renewal letters or inspection visits.

We can’t promise what any insurance company will do, and nobody honestly can. But clearing Zone 0 takes care of exactly the kind of thing an inspector notices first. More in our post on Zone 0, selling, buying, and insurance.

How to choose a Zone 0 fire safety company in Southern California

A lot of companies have started offering “Zone 0 services” this year. Before you hire anyone, ask:

Do they actually know fire behavior, or are they a landscaping crew with a new sign?
Do they know the rules for your specific city? San Diego, LA, and an unincorporated canyon area can all be different.
Can they handle trees properly? Trimming the wrong way can kill a tree you’re allowed to keep.
Do they haul it away, or leave you with a pile?
Are they straight about where the rules stand? Be careful with anyone saying you have to do everything right now, or promising they can “certify” your home. Only your local fire authority decides whether a property meets the rules.

He personally oversees every job, from the first walk-through to the last load on the truck. Read Robert’s story, or see all of our services.

Zone 0 questions from Southern California homeowners

Is Zone 0 the law in California yet?
Not statewide. The rules were approved in August 2026, but the Board pulled them back from final review in September, and there’s no effective date yet. The City of San Diego has its own rules already.

Is “Zone 0” the same as “Zone Zero”?
Yes. Same thing, two spellings. Both mean the first five feet around your home.

Do I have to remove all the plants around my house?
No. The strip right against your house has to be plant-free, but healthy, well-spaced plants can stay in the rest of the five feet.

Can I keep my trees?
In most cases, yes, as long as they’re healthy and trimmed to keep branches away from the roof, the chimney, and the eaves.

How much does Zone 0 work cost?
It depends on your property: how much needs clearing, whether trees need trimming, and whether you add gravel. That’s why we start with a free assessment and a clear quote.

Can you certify my home as Zone 0 compliant?
No one but your local fire authority can do that. We help you meet Zone 0 standards, and we’ll walk you through exactly what we did and why.

Get ahead of Zone 0

The rules are coming, and the easy stuff, like mulch, leaves, firewood, and gutters, is worth doing before fire season no matter what. Request a free Zone 0 assessment, or start with our one-minute Zone 0 self-check. Robert will walk your property and tell you exactly what your home needs.
