Create defensible space around your home
CAL FIRE zones 0, 1, and 2 are what stand between a wildfire and your house. Half the work is stuff a homeowner can do.
What you'll learn
- Zone 0 (0-5 ft): the ember-resistant zone and why nothing combustible belongs here
- Zone 1 (5-30 ft): spacing rules for shrubs, mulch choice, dead material removal
- Zone 2 (30-100 ft): canopy spacing, ladder fuels, and the 10-ft ground-to-limb rule
- What an insurance adjuster actually looks for in a defensible space inspection
Step by step
- Clear all dead leaves, pine needles, and debris from roofs, gutters, and the 5-ft zone.
- Move firewood, propane tanks, and flammable mulch at least 30 ft from the house.
- Limb up trees so the lowest branches are 10 ft above the ground.
- Space shrubs so the canopies don't touch each other or overhanging tree limbs.
- Schedule the tree-canopy and brush work every 2-3 years.
In fire-zone East County and the backcountry, defensible space isn't optional. Non-compliance shows up on insurance renewals and CAL FIRE inspections. Document your work with dated photos.

Walk your trees for warning signs
A 15-minute seasonal walk catches 80% of the failures that kill trees or drop limbs.
Prune small branches the right way
Branches under 2 inches are homeowner-friendly if you cut in the right spot. Cutting wrong invites decay.
