Zone Zero Landscaping Rules in Glendale

In the ember-resistant zone, the first 5 feet around your home, combustible mulch, dead vegetation, and flammable plantings have to go. The Glendale Fire Department, which already runs annual brush inspections in the hazard zones, will apply the final rules locally. The state draft has softened its stance on mature, well-maintained trees.
What Changes

What leaves the first five feet under Zone 0

  • Bark and wood mulch. The most common ember bed in Glendale yards. Replace with gravel, decomposed granite, or pavers inside the 5 foot band.
  • Dead and dying vegetation. Anything brown against the structure, including leaf litter in corners and under decks.
  • Flammable shrubs against siding. Junipers and similar resinous plants pressed against the house are the classic first ignition.
  • Firewood and stored combustibles. Wood stacks, lumber, and combustible storage move beyond 5 feet.

Beyond 5 feet, the existing defensible space rules keep applying: lean and green from 5-30 ft, reduced fuel from 30-100 ft, exactly the bands GFD already inspects.

About trees and shade: many hillside residents pushed back on early drafts that read like blanket vegetation removal, and the April 2026 state draft scaled that back. Well-maintained trees may be allowed near structures, subject to maintenance conditions. Glendale's own application of the final text will control here, so verify with GFD before removing any mature tree. Shade matters in a city that backs onto two mountain ranges.

A Zone 0 yard that still looks like a garden

Compliance is a materials question, not a beauty question. Glendale's hillside gardens can keep color in the first five feet with succulents, low ice plant, potted plants on noncombustible surfaces, and stone or DG ground cover. The structure of the yard stays; the fuel goes.

Ground plane

Gravel, decomposed granite, pavers, or concrete in the 0-5 ft band. No combustible mulch against the structure.

Plant palette

High-moisture, low-fuel plants, kept irrigated and litter-free. Avoid resinous species like juniper near walls and under vents.

Maintenance

The zone is only as good as its upkeep. Clear leaf litter from corners, under decks, and along fence lines, especially before Santa Ana season.

Landscaping questions Glendale homeowners ask

Will I have to remove mature trees near my Glendale home?

The April 2026 state draft scaled back blanket vegetation removal after public concern about mature trees and shade. Well-maintained trees may be allowed even near structures, with conditions like limbing up and clearing litter. The final text and Glendale Fire Department's local application will settle the specifics, so verify before cutting anything large.

Is bark mulch banned in the first 5 feet?

Combustible mulch is exactly the kind of material Phase 1 removes from the ember-resistant zone. Swap it for gravel, decomposed granite, pavers, or bare soil in the 0-5 ft band. Bark mulch stays fine beyond 5 feet.

How does this fit Glendale's existing brush inspections?

GFD's Vegetation Management Program already inspects hazard-zone parcels annually and requires defensible space within 100 feet, up to 200 feet where the Fire Marshal requires. Zone 0 adds a stricter near-structure band on top: the inspection you already get will eventually include the first 5 feet.
