Defensible Space in San Diego: Zone 0, Zone 1, and Zone 2
San Diego does not have one defensible space rule. It has several. Homes in State Responsibility Areas follow CAL FIRE’s standard. The unincorporated county follows the County Fire Code, which draws its zone lines differently. The City of San Diego has its own brush management rules, with Zone 0 arriving for new construction in 2026. Similar frameworks, different numbers.
A CWD assessment starts by identifying which authority answers for your parcel, and what its rules actually say.
Zone 0
The non-combustible first five feet. The newest requirement, landing on different timelines by jurisdiction.
Zone 1
Lean, clean, and green. The City draws this band at 5 to 30 feet. The County draws it at 5 to 50. Your authority sets yours.
Zone 2
Reduced fuel beyond Zone 1, out to 100 feet or your property line.

Home Hardening — Preparing Your Structure for Wildfire
Defensible space slows fire’s approach. Home hardening addresses the structure’s ability to survive ember intrusion and direct flame contact. Research by the Insurance Institute for Business and Home Safety (IBHS) shows embers, not flames, cause the majority of home losses in wildland-urban interface fires.
AB 38 disclosure requirement. Under California’s AB 38 (2019), sellers of homes in high and very-high Fire Hazard Severity Zones must disclose home hardening compliance to buyers at point of sale. Under California’s updated Wildland-Urban Interface Code (effective January 1, 2026), construction standards in fire hazard zones have been consolidated and strengthened.
CWD evaluates all 9 home hardening components established by CAL FIRE. Each has a full guide covering quick wins, retrofit options, full upgrades, code references, and applicable grants.
Grant Programs and Insurance Discounts
Several programs can offset the cost of defensible space and home hardening work for San Diego County property owners. Most homeowners don’t know these programs exist — or that an independent assessment is often the first step to qualifying. Verify program status and eligibility before applying; program windows and community lists change.
