Zone Zero Requirements in Glendale

Zone Zero (officially "Zone 0") is California's new ember-resistant zone law (AB 3074): the first 5 feet around your home must be kept free of combustible material if your parcel sits in a Very High Fire Hazard Severity Zone. In Glendale, the Glendale Fire Department enforces it, and the city's 2025 hazard remap put more than 16,000 Glendale homes in the Very High zone.

Why the first five feet

Two mountain ranges, one city, and embers in between

Glendale is flanked on both sides: the Verdugo Mountains to the north and west, the San Rafael Hills and Chevy Chase Canyon to the east. When Santa Ana winds push fire through either range, wind-blown embers travel far ahead of the flames and land in mulch beds, wood fences, and dry plants pressed against siding.

Glendale learned this the hard way in March 1964, when wind-driven fires swept the Verdugos and the San Rafael Hills on the same day and embers ignited homes blocks below the hillsides. The 2017 La Tuna Fire put roughly 250 Glendale homes under evacuation orders on the city's Verdugo side.

If your home sits near either range, from Whiting Woods to Chevy Chase Canyon, Zone Zero applies to you.

Glendale's 2025 hazard remap, at a glance
  • 16,383 homes now sit in the Very High Fire Hazard Severity Zone, an 83 percent increase over the prior maps.
  • 7,410 parcels were added to the Very High zone when the City Council adopted the new CAL FIRE maps on July 29, 2025.
  • Designated hazard areas grew from 12,242 acres to nearly 15,000 acres citywide.
First revision since 2011. If your street was outside the zone before, check again: the boundaries moved.

The Requirements

What Zone 0 requires, and when

The requirements arrive in phases. Rebuilds and new construction comply from day one.

ZONE 2 · 30-100 FT · REDUCED FUEL ZONE 1 · 5-30 FT · LEAN & GREEN ZONE 0 · 0-5 FT · NEW LAW YOUR HOME 5 ft
Zones 1 and 2 are California's existing defensible-space law, which Glendale Fire Department already inspects annually. Zone Zero adds the strictest band: the five feet where mulch, plants, fences, and stored items are regulated. Not to scale.
Phase 1

Clear the five feet

Mulch, dead plants, firewood, stored items: all of it leaves the 0-5 ft zone. Estimated deadline 2027-2028.

Phase 2

Replace what burns

Combustible fences, gates, and attached decks in the zone get replaced. The City of Glendale sets the deadline, up to 5 years after adoption.

Immediate

New fences & rebuilds

No new combustible fences in Zone Zero once regulations adopt. Rebuilds meet Zone Zero from day one, with no grace period.

Best Practice

Harden vents now

Ember-resistant vents are the highest-value upgrade you can make today. No deadline needed.

Who enforces it

Glendale Fire Department enforces Zone Zero here

Glendale is not CAL FIRE territory and not LA County Fire territory. The city runs its own municipal fire department, and Glendale parcels are a Local Responsibility Area: the city reviews, adopts, and enforces the hazard maps itself.

GFD's Vegetation Management Program already inspects thousands of hillside parcels every year in the designated hazard zones, requiring defensible space within 100 feet of structures, and up to 200 feet where the Fire Marshal calls for it. Zone Zero layers onto that existing program. Enforcement is education-first, per the April 2026 state draft.

Common Questions

Quick answers for Glendale homeowners

Is Zone Zero the same as Glendale's brush clearance inspections?

No. Glendale Fire Department's Vegetation Management Program covers defensible space out to 100 feet, and up to 200 feet where the Fire Marshal requires it. Zone 0 is stricter and closer: everything combustible in the first 5 feet, including fences, mulch, and stored items.

My home is below the hillsides. Does Zone Zero apply to me?

Check your parcel against the adopted maps. Glendale's 2025 remap added thousands of parcels to the Very High zone, and boundaries run well below the obvious hillside streets in areas near the Verdugo Mountains, the San Rafael Hills, and Chevy Chase Canyon.

Who enforces Zone Zero in Glendale?

The Glendale Fire Department. Glendale is a Local Responsibility Area with its own municipal fire department, so GFD, not CAL FIRE or LA County Fire, is the authority for Glendale parcels.

When do Glendale homeowners have to comply?

Final state regulations are expected late 2026. Rules for new fences and rebuilds apply immediately at adoption. Phase 1 clearing for existing homes is estimated for 2027-2028, and Phase 2 structural replacement follows on a schedule the City of Glendale sets, up to 5 years after adoption.
