Julianna and Mark Hayes have a lush Japanese garden in Marin County. They're pulling out nearly all the plants that hug the house anyway. The couple is spending about $100,000 to swap them for rocks, turf and pavers. No law told them to. She says her husband's thinking is, "Let's just get ahead of it."
What they're getting ahead of is Zone 0, the first 5 feet around a house. Best practice keeps that strip free of anything that burns. That means no plants or bark mulch, no wooden fence or patio chairs, and not even a jute doormat. Embers riding the wind start 60% to 90% of house ignitions, according to research by the Insurance Institute for Business & Home Safety. Todd Lando, a battalion chief with Central Marin Fire, helped set Marin County's 5-foot rule in 2018. It covers new construction and major remodels only. "It changes what sits directly against the house, not the whole landscape," he says.
The rule that isn't a rule yet
California has no statewide Zone 0 rule in force. The state's Board of Forestry and Fire Protection approved one in August for high-risk areas. It pulled the package back in September to clean up the wording. The board expects to resubmit it in November, a spokesperson said. If it's approved, it could reshape the yards of roughly two million structures. Until then, most of the pressure comes from insurers.
Ryan Elam, a retired software developer, is moving between two San Diego County homes. Both sit in Very High Fire Hazard Severity Zones on the state map. His longtime insurer refused to cover the new one because of fire risk, he says. The coverage he's shopping for will likely mean clearing plants, including two birch trees by the front door. For the house he's selling, he'll make whatever changes the buyer's insurer wants. "Real lawns won't exist," he says. Insurers and fire agencies don't coordinate, says Janet Ruiz of the Insurance Information Institute. Their Zone 0 rules still look alike, since both lean on the same science.
Pulling shrubs and raking out mulch costs close to nothing. At Yardzen, a national landscape design firm, a full redesign averages about $50,000. Demand there for fire-resilient design has more than tripled since 2024.
Our read
This is an insurance story wearing gardening gloves. We file it under Insurance and Consumer Protection (M11) and Housing (M6). In fire country, the insurer has a growing say in what a house is worth and what it costs to keep. Elam's longtime carrier wouldn't cover his new house. The next buyer's insurer gets to write the to-do list for his old one. The underwriters aren't waiting for the state, and anyone who plans to sell or renew in a fire zone shouldn't either. Lando says this changes the 5 feet by the wall, and nothing more. A clear strip is the goal, and a gravel moat is overkill.
Here's where it touches your own plan. It's your homeowners policy, if you own in a fire zone or plan to buy there. This week, find your renewal date. Then ask your agent, in writing, what the insurer wants in the 5 feet around your house. If you're buying, get a real quote before you close. Elam learned that a yes from your old carrier doesn't follow you to a new address. You clear the gutters before the wind picks up, and you read the policy before the renewal letter. If the answer changes what the house costs you, bring it to a review and we'll work the numbers with you.
