Wildfire Preparedness Services for San Diego County Properties
Independent assessments. Practical mitigation. Clear answers on what California law requires for your property.
Cal Wildfire Defense helps East County homeowners and rural landowners understand their fire risk, meet California’s defensible space and home hardening requirements, and access the grant programs available to fund the work. We start with an independent assessment, not a sales pitch, so you know exactly where you stand and what to do first.
Serving San Diego County and backcountry. Same-day and next-day appointments available.
Start With an Assessment
Before you spend money on mitigation work, you need to know what your property actually needs. CWD’s assessments give you an independent, documented picture of your fire risk — the kind of planning tool your contractor, insurance carrier, and grant applications can all use.
Property Fire Risk Walk
A walkthrough of your property covering defensible space, Zone 0, and the exterior of your home. We identify the highest-priority items, explain what California law requires for your property type and location, and give you a clear starting point.
Best for: Early planning, inspection prep, and most San Diego County landowners.
Structure Hardening Assessment
A deeper evaluation of your home’s exterior against California WUI Code standards and CAL FIRE’s home hardening component categories — roofs, vents, eaves, gutters, siding, windows, decks, fences, and accessory structures. Produces documentation suitable for insurance carriers, grant applications, and contractor planning.
Best for: Major retrofit work, insurance documentation, and grant applications.
Defensible Space — Zones 0, 1, and 2
California law requires defensible space on properties in State Responsibility Areas under Public Resources Code §4291 and Local Responsibility Areas under Government Code §51182. CWD’s assessments evaluate all three zones and produce a prioritized plan, not just a compliance checklist.
Zone 0 — 0 to 5 Feet
Non-combustible materials only. Enforced now in San Diego County under County Ordinance 10927. Mulch, wood decking, and combustible fencing are common violations.
Zone 1 — 5 to 50 Feet
Lean, clean, and green. San Diego County requires 50 feet of clearance in Zone 1, stricter than the state’s 30-foot baseline. Reduce fuel continuity, prune trees, remove dead material.
Zone 2 — 50 to 100 Feet
Reduce fire intensity. Thin vegetation, maintain spacing between plant canopies, and cut annual grass to a maximum of 4 inches.
San Diego County’s 50-foot Zone 1 requirement is cited by CAL FIRE at fire.ca.gov/dspace as a stricter local standard. Requirement set by the County of San Diego 2023 Consolidated Fire Code.

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.
