Wildfire Preparedness Services for San Diego County Properties
Independent assessments. Practical mitigation. Clear answers on what local law and compliance requires for your property now and in the future.
Cal Wildfire Defense helps San Diego area homeowners and landowners understand their fire risk and meet local defensible space and home hardening requirements.
Start With an Assessment
If you are new to oa Fire Severity Hazard Zone, before you spend money on defensible space or an fire proofing construction project, 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 contractors, home owners associations, and grant applications can all use.
Wildfire Risk Walk
An educational walkthrough of your property covering defensible space, Zones 0-2, and your home’s exterior. We flag the highest-priority items, explain what California and local law require for your property type and location, and leave you with a clear starting point. It’s the entry point — approachable and useful for almost everyone, without the in-depth documentation the other two assessments provide.
Best for: Early planning, inspection prep, quick estimates, and most San Diego County landowners.
Full Assessment
A deep, on-site evaluation of your structures and property — a thorough field assessment followed by a comprehensive written report and documentation, custom-built around your home and its specific needs. This is our full fire problem review: the reference document that maps your risks and requirements and can guide your decisions for years.
Best for: A comprehensive understanding of your property, its fire risks, and how it aligns with current and near-term regulations and wildfire preparedness posture.
Complete Plans
A full planning package for properties facing real work — not small projects, but larger transformations. Defensible space plans with fire-safe landscape design, contractor scoping and guidance, vegetation identification and setback definitions, plus a detailed evaluation of structures, existing building materials, applicable WUI codes, and Zone 0 complexities. Every aspect documented and ready to build or submit for outside approvals. This is a process, not a one-time service.
Best for: Homeowners preparing for a significant transformation of their property to meet wildfire risk and comply with current and near-term defensible space and Zone 0 laws.
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.
