Defensible space is an area around a structure where fuels are removed or reduced to provide a buffer between a structure and the surrounding area that is vital for protecting homes and communities from wildfire. Adequate defensible space acts as a barrier to slow or halt the progress of fire that would otherwise engulf a home or structure. It also helps ensure the safety of firefighters defending a structure. Defensible space is the first line of defense for homes and buildings against wildfire.

 

Defensible Space Zones

ZONE 0:  0'-5'
The area of defensible space within the first five feet of a home or other building. Keep this zone ember resistant by clearing the area from combustible material and plants.

Illustration of defensible space zones around a house: Zone 0 (0-5 ft), Zone 1 (5-30 ft), Zone 2 (30-100 ft).

ZONE 1: 5'-30'
This area reduces the chance of fire directly reaching your home. Properly space plants, shrubs and trees to provide fuel discontinuity. Zone 1 allows fire personnel to defend your home.

ZONE 2: 30'-100'
Designed to limit fire movement by reducing its height. Remove dead vegetation and reduce living vegetation to eliminate fuel ladders and create separate islands of planting.

OTHER BENEFITS
The California Department of Insurance “Safer from Wildfire” program identifies Defensible Space Zones as critical for protection. Some insurance companies are taking into account whether a home has implemented these standards.
