Zone 0 landscaping: what stays, what goes, and what about the trees

The ember-resistant zone rewrites the first 5 feet of your yard. It does not require scorched-earth landscaping, and the tree question deserves a straight answer.

Quick answer: Zone Zero requires noncombustible ground cover in the 0 to 5 foot ember-resistant zone: no bark mulch, no woody shrubs against the wall. The April 2026 draft scaled back blanket vegetation rules amid concern over mature trees and shade, and local authorities may allow well-maintained trees. Your Orange County fire authority sets the specifics.

The redesign

The five-foot ring, replanted

Out: bark and wood-chip mulch, juniper and other resinous shrubs, climbing vegetation on walls, and plantings under eaves and vents.

In: gravel and decomposed granite, pavers and stone, low succulents in noncombustible beds where your authority allows plantings, and clean hardscape paths that double as access.

On trees, honestly: homeowners across California pushed back on early drafts precisely because mature trees provide needed shade, and the state responded. The current draft is more permissive than the headlines suggested, and local rules may allow well-maintained trees near the home. Do not preemptively remove a healthy tree; verify with OCFA or your city's own department first.

Canyon properties

Where landscaping meets wildland

In the Santa Ana Mountain canyons and the county's foothill neighborhoods, Zone 0 is only the innermost ring: Zones 1 and 2 (5 to 30 and 30 to 100 feet) still govern the broader property. The free assessment covers all three zones, so canyon homeowners see the full picture, not just the first five feet.

Questions

Quick answers

Do I have to remove my trees?

In most cases, no. The April 2026 draft scaled back blanket vegetation restrictions after widespread public concern about mature trees and shade, and local rules may allow well-maintained trees. What Zone 0 clearly targets is combustible ground cover and shrubs in the first 5 feet. Verify specifics with your own fire authority before removing anything.

What replaces bark mulch in Zone 0?

Noncombustible ground cover: gravel, decomposed granite, pavers, stone, and concrete. Many Orange County front yards can swap the 5-foot ring to hardscape without losing the planting design further out.

Does drought-tolerant automatically mean fire-safe?

No. Some drought-tolerant plants are resinous and burn readily. In the ember-resistant zone the standard is noncombustible, not just low-water.
