A practical, step-by-step wildfire home preparation guide for LA homeowners: defensible space zones, ember-resistant vents, roof and gutter clearing, vegetation trimming, and a ready go-bag.
Wildfire home preparation comes down to two jobs: clear a defensible space around your house, and seal the small gaps where embers get in. Do both before fire weather arrives, not during it. Most homes lost in a wildfire aren't consumed by a wall of flame. They ignite from wind-blown embers that land in dry debris, drift through an open vent, or catch on a wood fence, according to CAL FIRE.
That's actually good news for you. Embers are something you can plan against with a weekend of work and a few smart upgrades. This guide walks through the practical steps, in order, for a typical LA-area home. We'll flag where a homeowner can handle it and where a pro or specialist earns their fee.
Key Takeaways
- Defensible space works in zones. CAL FIRE splits the area around your home into Zone 0 (0–5 feet), Zone 1 (5–30 feet), and Zone 2 (30–100 feet). Start closest to the house and work outward.
- Embers cause most home losses. Screening vents with 1/8-inch metal mesh and clearing debris from roofs and gutters blocks the most common ignition paths.
- Keep the first five feet bare. Zone 0 — right against your walls, deck, and fence line — should have nothing that burns easily.
- The City of LA requires brush clearance to 200 feet of structures in high-fire-hazard areas, per the LAFD.
- Pack a go-bag now. Ready.gov and CAL FIRE both recommend a grab-and-go kit and knowing the "6 P's" before an evacuation order.
- Call a pro for the roof and vent retrofits. Steep roofs and code-rated ember-resistant vents are worth doing right.
Step 1: Set up your defensible space, zone by zone
Defensible space is the buffer between your home and whatever can burn around it. CAL FIRE and ReadyForWildfire.org break it into three zones, measured out from your walls. Work from the house outward.
Zone 0 — the first 0 to 5 feet. This is the ember-resistant zone, and it matters most. Keep it clear of anything that ignites easily: dead leaves, wood mulch, firewood stacks, dry plants, and combustible patio furniture. CAL FIRE recommends hardscape here — gravel, pavers, or bare soil instead of bark. Move the woodpile and the recycling bins away from the wall.
Zone 1 — 5 to 30 feet. Remove dead plants, grass, and weeds. Clear leaves and needles from the yard and off the roof and gutters. Prune tree branches so they don't touch the house, and keep firewood stacks out of this zone.
Zone 2 — 30 to 100 feet. This is about slowing a fire down before it reaches the house. Cut annual grasses to a low height. Create horizontal and vertical spacing between shrubs and trees so flames can't ladder up or hop across. On a slope, space plants farther apart, since fire climbs faster uphill.
In the City of Los Angeles, brush clearance rules go further than 100 feet. The LAFD requires year-round clearance of hazardous vegetation within 200 feet of structures in designated brush zones. If you're in a hillside neighborhood, check your annual brush clearance notice for the specifics.
Step 2: Clear your roof and gutters of debris
Your roof and gutters are the number-one ember trap. Dry pine needles and oak leaves collect in gutter troughs and roof valleys, then catch a falling ember like kindling. Clear them out before fire season and again after any Santa Ana wind event.
Get debris off the whole roof, not just the gutters — pay attention to valleys, behind the chimney, and where a lower roof meets a wall. Then flush and clear the gutters completely. If you're not sure how to do it safely, our gutter-cleaning walkthrough covers ladder safety and the right tools.
For homes under heavy tree cover, noncombustible metal gutter guards cut down how often debris piles up. CAL FIRE recommends noncombustible gutter covers to keep the trough from filling with fuel in the first place.
Step 3: Screen and cover your vents against embers
Vents are the hidden weak point. Attic, eave, foundation, and gable vents pull air — and embers — straight into your home's cavities, where they can smolder unseen. This is one of the most overlooked parts of home wildfire prep.
Cover every vent opening with corrosion-resistant metal mesh. CAL FIRE and the California Building Code call for 1/8-inch metal mesh (some agencies allow 1/16-inch). Never use plastic or fiberglass screening — it melts and burns right through. For a lasting fix, ember-resistant "WUI" vents are built and tested to block embers and flame.
Retrofitting vents to code is a good place to bring in help. The mesh has to be installed without blocking required airflow, and gable and under-eave vents can be awkward to reach. If you'd rather not climb, hire a vetted local handyman to screen the accessible vents and flag any that need a specialist.
Step 4: Trim vegetation and break up the fuel
Plants aren't the enemy — dry, dense, poorly spaced plants are. Your goal is separation, so fire can't run from one fuel source to the next.
- Trim tree limbs up off the ground. For taller trees, the LAFD requires clearing lower branches so no foliage hangs within 6 feet of the ground. This stops a ground fire from climbing into the canopy.
- Keep branches away from the house and roof. Give at least 10 feet of clearance between tree limbs and your chimney or roofline.
- Space out shrubs. Break up continuous hedges, especially on slopes, so flames can't spread plant to plant.
- Pull dead material. Dead grass, dry leaves, and brittle branches are prime ember fuel. Clear them from beds and from under decks.
Keep plants near the house well-watered and healthy during fire season. A hydrated, maintained landscape resists ignition far better than a neglected one.
Step 5: Close the small gaps around the house
Once the big fuel is handled, seal the little openings embers exploit. These are quick, low-cost wins:
- Fences and gates. A wood fence that touches your house is a fuse leading straight to the wall. Swap the last few feet to metal, or add a noncombustible gap where it meets the structure.
- Decks and porches. Keep the area under decks clear of stored items, leaves, and firewood. Box in open under-deck space if you can.
- Door and garage seals. Add weatherstripping and a tight garage-door bottom seal so embers can't blow underneath.
- Windows and siding. Repair damaged screens and seal gaps in siding and trim. These fixes double as everyday upkeep — see our exterior home maintenance guide for the full seasonal checklist.
Step 6: Stage a garden hose and firefighting tools
Keep a garden hose long enough to reach every side of your house, connected and ready. Add a nozzle that produces a strong stream. CAL FIRE also recommends keeping basic hand tools on hand — a shovel, rake, axe, or hoe — to knock down spot fires or clear a path.
Know where your water shutoffs are, and keep a ladder accessible so firefighters can reach your roof. If you're on a well and lose power, note that your pump won't run — plan a backup water source.
Step 7: Pack a go-bag and know the 6 P's
Preparation isn't only about the structure. When an evacuation order comes, you may have minutes. Ready.gov recommends an emergency supply kit you can grab and go.
Go-bag basics: water and non-perishable food, a manual can opener, a first-aid kit, current medications, a flashlight with extra batteries, a battery or hand-crank radio, phone chargers, cash, and copies of important documents. Pack sturdy shoes and long cotton clothing to protect against heat and sparks, and don't forget carriers, food, and water for pets.
CAL FIRE frames the last-minute checklist as the 6 P's:
- People and pets — plus a meeting point and escape routes you've practiced.
- Papers — IDs, passports, insurance cards, and important documents.
- Prescriptions — a full current supply, plus eyeglasses and health supplies.
- Photos and irreplaceable mementos.
- Personal computer — laptops and hard drives with your key files.
- Plastic — credit and debit cards and cash, since power outages can down ATMs.
Sign up for local emergency alerts, and know your neighborhood's evacuation routes before you need them.
When to bring in a pro
Plenty of this is honest weekend work: clearing gutters, raking Zone 0, trimming low shrubs, staging a hose, and packing a go-bag. A few jobs are worth handing off. Steep or tile roofs, hard-to-reach gable vents, and code-rated ember-resistant vent retrofits reward a steady hand and the right ladder. Ongoing brush clearance on a hillside lot is another one many homeowners choose to hire out.
