Do Altadena Yards Have to Change for Zone 0?
Zone Zero Altadena / Landscaping
Altadena is a town of big trees. This is not a war on them.
This community's identity is written in its canopy: the deodar cedars of Christmas Tree Lane, the oaks and sycamores of the foothill streets. After the Eaton Fire, surviving mature trees became even more precious. So say it plainly: we have not identified any Altadena rule that orders healthy mature trees removed, and this page does not recommend removing them.
The first-five-feet approach is about fuel against the structure: mulch beds against siding, dead material, resinous shrubs under windows. A healthy tree whose trunk stands well away from the house is a different question.
Local rules decide the fine print. If Los Angeles County adopts a Zone 0 rule for Altadena, it would set how overhanging limbs and trunk placement are treated. Until then, confirm specifics with LA County Fire and do not remove healthy trees based on rumor.
Replanting after the fire: Zone 0 from bare dirt
Many Altadena lots are being landscaped from nothing. That is a hard fact, and one real advantage: a bare lot can be designed with a noncombustible first five feet at little extra cost.
Hardscape the first five feet
Decomposed granite, pavers, or stone against the structure. Planting beds start at the 5-foot line, not at the wall.
Shade without fuel
Plant new trees so canopies mature away from the roofline, and keep the drip line maintained. Shade and compliance are not enemies.
Standing homes: clear, then keep clear
Rake out mulch, remove dead material, relocate shrubs pressed against siding. For many yards this is a weekend of work.
Mind the wind path
Wind-driven embers land on the sides of a house most exposed to the wind. Harden those five feet first, then the rest.
Landscaping questions, answered
Do I have to change my yard for Zone 0 in Altadena?
As of September 19, 2026 we have not identified a local Zone 0 ordinance for Altadena. The statewide Zone 0 draft is Proposed — not in force. Clearing the first five feet is Recommended now. Confirm with LA County Fire before acting on any deadline.
Will Zone 0 force Altadena to cut down its deodars and mature trees?
We have not identified any Altadena rule that orders healthy mature trees removed, and the statewide Zone 0 draft is Proposed — not in force. The first-five-feet approach is about fuel against the structure: mulch against siding is a different question from a healthy tree whose trunk stands well away. Confirm specifics with LA County Fire.
What should leave the first 5 feet?
Recommended now: combustible mulch, dead or dying vegetation, woody shrubs against the wall, firewood stacks, and combustible planter boxes. Hardscape, stone, gravel, bare soil, and low-fuel plantings are the replacements.
I am replanting a rebuild lot from bare dirt. What should I do differently?
Design the first five feet as hardscape from the start: decomposed granite, pavers, stone, or bare-earth pathways against the structure, with planting beds beginning beyond the 5-foot line. On a bare lot this costs little extra and avoids retrofitting later.
Does gravel or rock mulch work in the first five feet?
Yes. Rock, gravel, decomposed granite, and pavers are noncombustible and are the usual choices for the first five feet. Rubber and bark mulch are combustible and are not recommended there.
Keep the garden. Lose the fuel.
