Zone Zero: The 5 Feet That Decide If a Home Ignites

Most homes lost in wildfires don’t ignite from flames. They ignite when embers reach the structure—especially in the first 0–5 feet around the home.

What is Zone Zero?

Zone Zero refers to the 0–5 foot perimeter around a structure where ember ignition risk is highest. Under AB 3074, this area is moving toward ember-resistant, non-combustible standards in wildfire-prone regions.

0–5 feet from the structure
Focus: ember ignition prevention
Goal: remove or replace combustible materials closest to the home

Why Homes Ignite Without Flames

Wildfires generate wind-driven embers that can travel ahead of fire fronts and ignite vulnerable points like rooflines, vents, eaves, and combustible materials near the structure.

Zone Zero is the ignition zone—this is where prevention matters most.

Zone Zero Checklist (Quick Version)

To prepare for Zone Zero standards, homeowners typically need to address combustibles within five feet of structures.

✓

Remove wood mulch, dry debris, and dead vegetation within 5 feet

✓

Replace ground cover with gravel, stone, concrete, or hardscape

✓

Move combustible items (woodpiles, patio cushions, bins) away from the structure

✓

Keep gutters/rooflines clear of debris

✓

Ensure fences/gates attached to structures are non-combustible

✓

Reduce ember entry points (vents/screens/material transitions)

When Will AB 3074 Be Enforced?

Enforcement timelines are developing through state regulation. Regardless of formal enforcement, insurance carriers are increasingly using Zone Zero principles when evaluating renewals in high-risk areas.
