Zone Zero Fire Safety: What San Diego Homeowners Need to Know
What is Zone Zero
Zone Zero refers to the area extending from zero to five feet out from your home, attached structures, and decks — the closest perimeter to your building.
Traditional defensible space plans in California typically include:
Zone 0 (0–5 feet) — Ember-resistant zone
Zone 1 (5–30 feet) — Lean, clean, green zone
Zone 2 (30–100 feet) — Reduced fuel zone
Ultimately, Zone Zero aims to remove or reduce anything that could catch fire next to your home, such as:
Wooden and vinyl fences or gates
Bark mulch, wood chips, and most artificial turfs
Wooden lawn furniture
Combustible planters or decor
Where does Zone Zero Apply?
Zone Zero applies to homes within Local Responsibility Areas (LRA) or Very High Fire Hazard Severity Zones (VHFHSZ), which is about two-thirds of San Diego — this includes areas like Scripps Ranch, Rancho Bernardo, and Carmel Valley, along with parts of more densely populated neighborhoods like Bankers Hill and Hillcrest.

Are you Zone Zero Compliant?
If you’re unsure whether Zone Zero applies to your property in San Diego County, you can start by checking your wildfire risk classification on the CAL FIRE Fire Hazard Severity Zone maps. These maps show areas designated by risk level, which often aligns with the jurisdictions where Zone Zero rules are being implemented.
Steps to get started:
Visit the CAL FIRE Fire Hazard Severity Zone map (searchable by address).
Determine whether your home sits in a Very High or High Fire Hazard Severity Zone.
Measure the 5-foot perimeter around your home’s walls, decks, and attached structures.
Inventory combustible materials — including fences — and plan upgrades if needed.
Taking early action not only enhances home safety but also helps with insurance and resale value down the line.
