Zone Zero · City & County of San Diego

Home Hardening in San Diego

Home hardening under Zone Zero means the first 5 feet, the ember-resistant zone around your home, can't feed a fire: what's on the ground, what's against the walls, and what's attached to the structure. Two categories, fences and landscaping, carry San Diego Fire-Rescue's own legal deadlines. The rest decide whether your home survives an ember storm.

In Effect + Phase 2

Fences & gates

New combustible fences have been banned in the zone since February 28, 2026; existing ones get a Phase 2 window, targeted for February 2027.

Phase 1

Landscaping

Combustible mulch, dead vegetation, and plants against the structure leave the first five feet. San Diego's own target: February 2027.

Decks & patios

Attached combustible decks inside the zone are built items. Expect them in Phase 2, with material and clearance requirements.

Best practice

Roof & gutters

Embers land on roofs first. Clean gutters, gutter guards, and Class A roofing protect everything the zone work buys you.

Best practice

Vents & openings

Fine-mesh ember-resistant vents block the most common path fire takes into a house: through the attic and crawlspace.

Best practice

Sheds & outbuildings

A combustible shed within 5 feet of the house is part of your Zone Zero. Move it, harden it, or plan around it.

The Order of Operations

Where to start

1

Clear before you build. Phase 1 landscaping work is the cheapest step and the first deadline San Diego Fire-Rescue is asking for. Do it before any structural spending.

2

Break the fence fuse. The fence-to-house connection is the highest-risk five feet on the property and often a small, targeted fix.

3

Then chase embers upward. Gutters, vents, and deck clearance turn a compliant yard into a survivable home.
