Keep your property lean and green to help protect your family and home.

Defensible space is essential to improve your home’s chance of surviving a wildfire. It’s the buffer you create between a building on your property and the grass, trees, shrubs, or any wildland area that surround it. This space is needed to slow or stop the spread of wildfire and it helps protect your home from catching fire—either from direct flame contact or radiant heat. Defensible space is also important for the protection of the firefighters defending your home.

Zone 1

Zone 1 extends 30 feet* from buildings, structures, decks, etc.

  • Remove all dead plants, grass and weeds (vegetation).
  • Remove dead or dry leaves and pine needles from your yard, roof and rain gutters.
  • Remove branches that hang over your roof and keep dead branches 10 feet away from your chimney.
  • Trim trees regularly to keep branches a minimum of 10 feet from other trees.
  • Relocate wood piles to Zone 2.
  • Remove or prune flammable plants and shrubs near windows.
  • Remove vegetation and items that could catch fire from around and under decks.
  • Create a separation between trees, shrubs and items that could catch fire, such as patio furniture, wood piles, swing sets, etc.

Zone 2

Zone 2 extends 100 feet out from buildings, structures, decks, etc.

  • Cut or mow annual grass down to a maximum height of 4 inches.
  • Create horizontal space between shrubs and trees. (See diagram)
  • Create vertical space between grass, shrubs and trees. (See diagram)
  • Remove fallen leaves, needles, twigs, bark, cones, and small branches. However, they may be permitted to a depth of 3 inches.

* San Diego County requires 50 feet of clearance in Zone 1. Check with your local fire department for any additional defensible space or weed abatement ordinances.

Plant and Tree Spacing

The spacing between grass, shrubs, and trees is crucial to reduce the spread of wildfires. The spacing needed is determined by the type and size of brush and trees, as well as the slope of the land. For example, a property on a steep slope with larger vegetation requires greater spacing between trees and shrubs than a level property that has small, sparse vegetation.

Vertical Spacing

Remove all tree branches at least 6 feet from the ground.

Allow extra vertical space between shrubs and trees. Lack of vertical space can allow a fire to move from the ground to the brush to the treetops like a ladder.
