Defensible Space

The 3-Zone Defense System

California Fire Code requires homeowners to maintain defensible space in concentric zones around their home. Each zone serves a specific purpose in slowing fire spread and protecting your structure.

Zone 2 · 30–100ft · Reduced Fuel Zone
Zone 1 · 0–30ft · Non-Combustible Landscaping

Zone 0

0–5ft

The Structure

Zone 0

Home itself

Zone 1

30ft buffer

Zone 0

30–100ft

Zone 0 · 0–5 feet

The home itself and immediate surroundings. This zone focuses on the structure — fire-resistant materials, ember-proof vents, non-combustible decking, and sealed gaps.

Zone 0 · 0–5 feet

Lean, clean, and green. Irrigated plants with adequate spacing, no wood mulch, no combustible fences, and hardscaping elements that slow fire movement.

Zone 0 · 0–5 feet

Reduced fuel zone. Remove dead plant material, create separation between plants, prune tree canopies, and mow grasses below 4 inches to prevent fire spread.
Action Checklist

12 Actions to Harden Your Home

Organized into three categories — tackle them in order for the highest impact per dollar spent.

Roof & Structure

Ember-Resistant Vents

Install 1/16" wire mesh screens on all attic, crawl space, and foundation vents to block ember intrusion.

Class A Roofing Materials

Use fire-rated asphalt shingles, metal, clay tile, or concrete tile — all rated Class A for maximum flame spread resistance.

Metal Gutters with Mesh Guards

Replace plastic gutters with non-combustible metal and add mesh guards to prevent debris and ember accumulation.

Fire-Resistant Siding & Stucco

Stucco, fiber cement, or brick siding dramatically reduces ember ignition risk on the exterior wall surfaces.

Landscaping

30ft Non-Combustible Zone

Maintain a bare earth or gravel buffer within the first 5 feet of your foundation — no plants, mulch, or wood.

Space Plants Apart

Keep shrubs and trees separated so fire cannot ladder from ground fuel to tree canopy. Prune lower branches to 6–10ft.

Remove Dead Vegetation

Dead plants, leaves, and grass are the most dangerous fuels. Clear them annually — especially before fire season.

Avoid Wood Mulch Near Foundation

Use gravel, decomposed granite, or rock mulch within Zone 0. Wood chips act as a wick for ember-driven ignition.

Emergency Preparedness

Go-Bags Ready

Prepare 72-hour emergency bags for each family member with documents, medications, water, and essentials.

Evacuation Routes Mapped

Know at least two exit routes from your neighborhood. Drive them in advance and share with every family member.

Important Docs Backed Up

Scan and store insurance policies, IDs, deeds, and financial records in a secure cloud account.

Family Communication Plan

Designate an out-of-area contact point, set meeting locations, and ensure every family member has the plan memorized.

Risk Comparison

Protected vs. Unprotected

The difference between a home that survives a wildfire and one that doesn't often comes down to preparation made months before the fire arrives.

Unprotected Home

  • Wood shake or asphalt shingles easily ignited by embers
  • Plants and wood mulch touching the foundation
  • Plastic gutters filled with dry debris
  • No ember-blocking vent screens installed
  • Dense, un-pruned vegetation within 30ft
  • Dead grass and leaves accumulated under decks
  • No family evacuation plan in place
  • Critical documents stored only on-site

Protected Home

  • Class A metal or tile roof with ember-resistant vents
  • 5ft gravel/stone buffer around entire foundation
  • Metal gutters with mesh guards — cleared seasonally
  • 1/16" mesh screens on all vents and openings
  • Spaced, irrigated low-fuel plants in Zone 1
  • Zero dead vegetation within 100ft of the structure
  • Go-bags packed, two evacuation routes memorized
  • Docs backed up to cloud and out-of-state contact set
