Fire-safe yards: Zone 0, defensible space and insurance.

Most homes lost to wildfire are lit by embers, not by a wall of flame. Wind carries burning embers ahead of a fire, and they land in mulch, dry plants, wood fences and debris right next to the house. Zone 0 is the first five feet around a home, where keeping things non-combustible matters most.

• Where the rule stands. The California Board of Forestry and Fire Protection approved a statewide Zone 0 rule on August 19, 2026. It is not in effect yet. The state's Office of Administrative Law lists the filing as withdrawn on September 8, 2026, and the Board says it is still working on a final review. Until the final rule is published, there is no statewide Zone 0 deadline, and the details could still change.
• Where it would apply. In the version the Board approved: all homes in State Responsibility Areas, and homes in Very High Fire Hazard Severity Zones inside cities. In our area that includes many properties in Fallbrook, Valley Center, De Luz and the hillsides around Temecula, Murrieta, Escondido and San Marcos.
• Timing once it takes effect. A few basics apply right away, such as clean roofs and gutters, no firewood in Zone 0 and no dead branches over the house. The rest phases in for existing homes over about three to five years. Requirements for new construction wait until the Board publishes its final guidance.
• What already applies. Zone 1 and Zone 2 defensible space is already required by state law in many areas, and some local fire agencies have their own rules. Check with yours.
• Check your property. CAL FIRE's fire hazard severity zone map shows whether your address is in a mapped zone. The link is in the sources at the bottom of this page.

Why do it now? CAL FIRE already recommends Zone 0 for every home in fire country, and California's Safer from Wildfires insurance program already counts a five-foot ember-resistant zone today. Building it into a yard project now is usually simpler than tearing it out later.

Zone 1 and Zone 2 requirements already apply to many properties under state defensible-space law. Zone 0 is the new piece. It isn't required yet, and it is the one most yards don't meet today.

The version the Board of Forestry approved in August covers the five feet out from the walls, attached decks, stairs and pergolas, or to the property line if that is closer. It calls for:

• No combustible ground cover. Remove wood mulch, bark, wood chips and built-up leaves and needles, with limited exceptions.
• No firewood or debris. Firewood is stored outside Zone 0, and roofs and gutters are kept clear.
• Clear under decks and stairs. No plants or stored combustibles under decks, balconies, pergolas and stairs.
• Trimmed trees and shrubs. Dead branches and ladder fuels are removed, with clearance kept from the chimney, roof, eaves and walls. Plants are kept back from the walls, windows, doors and vents.
• No wood fences against the house. Combustible fences and gates can't attach to the home, and new fencing in Zone 0 must be non-combustible.
• Small outbuildings. Sheds under 120 square feet can stay in Zone 0 only if they are fully non-combustible. In practice, we recommend keeping sheds and anything stored in them, like fuel, furniture and boxes, out of Zone 0 entirely.

Inside cities, local agencies can adopt alternative practices that work about as well, and local rules can also be stricter. Because the rule isn't final, we confirm the current requirements with the Board of Forestry and your fire agency before we finalize a plan.

Zone 0 doesn't have to look like a gravel moat. Done well, it reads as a clean border that frames the house.

• Non-combustible surfaces. Pavers, concrete, decomposed granite, gravel or river rock against the house. We pick the material to match the patio, walks and style of the home.
• No wood mulch. Bark and wood chips come out of Zone 0. Rock or decomposed granite replaces them, and some decorative rock products contain organic material, so we specify mineral-only products.
• Drainage stays right. The new surface still has to slope away from the foundation and stay below the weep screed. We design Zone 0 and drainage together. See our storm-ready yards guide.
• Irrigation moves out. Sprinkler heads and drip lines are relocated to the planting beds beyond five feet, and spray heads are adjusted so they don't hit the walls.
• Clean edges. Metal or concrete edging separates the Zone 0 border from planting beds, so mulch and soil don't creep back in.
• Planting moves outward. The color and greenery move to Zone 1, where plants can be watered and spaced properly. From the street, the yard still looks planted.

A wood fence attached to the house acts like a fuse. Embers ignite the fence, and the fire walks along it to the wall. The California Department of Insurance calls replacing wood fencing connected to the home with metal "critical."

• The first five feet. Where a fence or gate meets the house, the first five feet should be metal or another non-combustible material.
• Beyond five feet. The rest of the fence can be another material. Vinyl, block or metal are common choices, and we match the look so the transition is clean.
• Gates. Side-yard gates next to the house are part of this. A metal gate with a matching section of metal fence usually covers it.
• HOAs. Many HOAs control fence materials and colors, so we include fencing in the HOA plan when needed.

• Remove from Zone 0. Shrubs, hedges and dry plants against the house, especially dense shrubs that collect dead material inside. Junipers, eucalyptus, pampas grass, dry ornamental grasses and other resinous or twiggy plants are common problems near homes.
• Zone 1 planting. Lower plants with high moisture content, spaced so fire can't jump from plant to plant, and watered on a schedule. Succulents, low ground covers and well-irrigated perennials are common choices.
• Fire-resistant is not fireproof. Any plant can burn if it is dry or neglected. Spacing, watering and removing dead material matter more than the plant list.
• Grass in Zone 2. Annual grasses and weeds should be cut to four inches or less.
• Maintenance. A fire-safe yard stays fire-safe only if dead leaves, branches and debris are cleared regularly, especially before fire season.

• Overhanging branches. Remove dead branches over the roof and near windows, and keep branches at least ten feet from a chimney or stovepipe.
• Trees inside five feet. Under the approved rule, some existing trees can stay if they are maintained and kept clear of the house. Others are better removed, especially if they drop debris on the roof, crowd the walls or have aggressive roots near the foundation.
• Replace, don't just remove. When a tree comes out, we usually design a new focal tree or planting farther from the house, so the yard keeps its shade and character.
• Ladder fuels. In Zones 1 and 2, lower limbs are trimmed and shrubs are kept out from under trees, so a ground fire can't climb into the canopy.

• Under decks. Clear plants, weeds and debris from under decks and stairs. Concrete, gravel or bare soil are acceptable underneath.
• Sheds and outbuildings. The Safer from Wildfires program asks that combustible sheds, gazebos, playhouses and similar structures be moved at least 30 feet from the home.
• Six inches at the base of the walls. Keep at least six vertical inches of non-combustible material at the bottom of exterior walls, measured from the ground and from attached surfaces like decks. This often means lowering soil and mulch along the house, which also helps drainage.
• Firewood and propane. Firewood stacks don't belong in Zone 0 or Zone 1. State guidance calls for ten feet of clearance around exposed woodpiles and propane tanks.

Under California Department of Insurance rules, insurers must offer discounts for the steps in the state's Safer from Wildfires program. The state says every action on the list qualifies for a discount, but the amount and how it is applied depend on each insurer's approved rating plan. The landscape-related actions are:

• A five-foot ember-resistant zone around the home, including fencing.
• Clearing vegetation and debris from under decks.
• Moving combustible sheds and outbuildings at least 30 feet from the home.
• Meeting state and local defensible-space requirements.

What we can and can't promise. We design to the Zone 0 standard and the Safer from Wildfires measures, and we document the work with photos and a plan you can give your insurer. Each insurer applies its own discounts, verification and underwriting, so we can't promise a discount or a policy. If your coverage is through the California FAIR Plan or another insurer, ask them which measures they credit and what proof they need before work starts.

The rest of the Safer from Wildfires list covers the building: a Class A roof, ember-resistant vents, enclosed eaves and upgraded windows. That work is done by roofers and general contractors, not landscapers. Vents are where the yard and the house meet: burning mulch or plants next to a foundation or crawlspace vent can push embers inside, so we keep Zone 0 clear in front of every vent, and ember-resistant vent screens are worth asking your contractor about. We coordinate with licensed partners when a project includes it, so the yard and the house are planned together.

• Remove wood mulch, bark and debris within five feet of the house.
• Use a non-combustible surface, like pavers, decomposed granite or rock, against the walls.
• Pull plants back from the walls, windows, doors and vents.
• Clear plants and stored items from under decks and stairs.
• Replace the first five feet of wood fence and gates at the house with metal.
• Clear leaves from the roof, gutters and the base of the walls.
• Remove dead branches over the roof, and keep branches ten feet from the chimney.
• Move firewood and combustible sheds away from the house.
• Cut dry grass and weeds to four inches or less.
• Check your address on CAL FIRE's fire hazard severity zone map.
