Defensible Space Clearing in San Diego County
Help protect your home and property with professional brush clearing, tree thinning, and vegetation management from Bar D Bar Landworks Inc.
Defensible space is the maintained area between your buildings and the surrounding vegetation. Removing excess fuel and separating trees and shrubs can reduce wildfire intensity, limit pathways for fire to reach your home, and give firefighters a safer place to work.
Creating defensible space does not mean clearing your entire property to bare dirt. It means managing vegetation strategically, starting closest to your home.
Understanding Defensible Space Zones
California’s general defensible space guidance identifies Zone 0 within 5 feet, Zone 1 from 5–30 feet, and Zone 2 from 30–100 feet.
San Diego County’s guidance for unincorporated areas extends Zone 1 to 50 feet, with Zone 2 continuing from 50–100 feet. The following overview uses those local distances. Your fire district, approved fire protection plan, and property conditions may impose additional requirements.
Zone 0: Ember-Resistant Area — 0–5 Feet
The area immediately next to your home deserves special attention. Windblown embers can ignite materials against a building, allowing fire to spread to the structure.
San Diego County’s local code calls for continuous hardscape or noncombustible materials in this zone, measured from exterior walls and applicable patios, decks, and building attachments.
Use noncombustible surfaces such as gravel, pavers, or concrete.
Remove bark mulch, wood chips, dry vegetation, and combustible debris.
Keep firewood and lumber outside this area.
Keep roofs, gutters, porches, decks, and stairways free of accumulated combustible debris.
Zone 1: Maintained Landscape — 5–50 Feet
Maintain a landscape with limited fuel and separation between vegetation.
Remove dead or dying vegetation and accumulated leaves and needles.
Maintain low-growing, drought-tolerant, fire-resistant landscaping with irrigation as required by your district.
Separate shrubs and trees to interrupt continuous paths of vegetation.
Prune trees to reduce contact with buildings and remove branches within 10 feet of chimney or stovepipe outlets.
Fire-resistant plants still require regular maintenance; no plant is fireproof.
Zone 2: Reduced-Fuel Area — 50–100 Feet
Reduce fuel in the outer zone while retaining appropriately spaced, healthy vegetation.
Cut annual grasses to a maximum height of 4 inches.
Thin dense brush and remove dead vegetation.
Create horizontal separation between trees and shrubs.
Remove lower branches and vegetation beneath trees to reduce ladder fuels.
Steeper slopes may need greater vegetation spacing. Where your property boundary is closer than 100 feet, confirm the required treatment with your local fire authority before planning work.
