Does Zone 0 Change Landscaping in Hidden Hills?
Zone Zero Hidden Hills / Landscaping
What to change at the foundation line: Recommended now
The first five feet is mostly a ground-layer question. Wood mulch, bark, dead leaves, dry ornamental grasses, and firewood stacks are the first things to move out. What replaces them: gravel, decomposed granite, pavers, stone, bare soil, and hardscape that reads perfectly natural on a ranch-style lot.
On an equestrian property the ground layer includes things a suburban checklist never mentions: hay storage, shavings and bedding piles, and paddock footing materials stacked against barn walls. Those are the first things to move away from the walls.
Out of the zone
Combustible mulch, dead plants, dry grasses, leaf litter, firewood, hay, shavings, and stored combustibles within 0-5 ft of any structure.
Into the zone
Gravel or decomposed granite beds, stone borders, pavers, irrigated low-fuel plantings in noncombustible containers.
Case by case
Mature trees, established hedges, and specimen plantings near structures. We have not identified a local rule on these, and the statewide draft is not in force. Confirm with LA County Fire and the city before removing established trees.
The oak question, answered honestly
Public discussion of Zone 0 has raised the worry that it means stripping greenery, and shade, from around homes. No rule we identified requires removing healthy mature oaks in Hidden Hills for Zone 0. No statewide regulation is in force, and we have not identified a local ordinance.
The practical priority is dead material and ground fuels near structures: dead fronds, leaf litter, and resin-heavy shrubs against a wall matter far more than a healthy, irrigated, limbed-up tree.
Two honest caveats: the statewide draft is not in force and could change, and tree-by-tree questions belong to the fire authority and the city, not to any website. Confirm with LA County Fire and the City of Hidden Hills before you cut, and before you assume you must.
Landscaping questions, answered
Is Zone 0 required for landscaping in Hidden Hills?
Not by any rule we have identified. As of September 19, 2026 no statewide Zone 0 regulation is in force, and we have not identified a local Zone 0 ordinance for Hidden Hills. Existing law (PRC §4291 and Gov. Code §51182) requires roofs and gutters to be kept clear of leaves and needles.
Do I have to remove my mature oaks?
No rule we identified requires it. The statewide draft is Proposed — not in force, and we have not identified a local ordinance. The practical priority is dead material and ground fuels near structures. Confirm with LA County Fire and the city before you cut.
Is wood mulch a problem in the first five feet?
Recommended now: replace it. Combustible mulch against a foundation can carry embers to the wall. Gravel, decomposed granite, pavers, or bare soil are noncombustible replacements at the foundation line.
What about hay, shavings, and manure piles near the barn?
Hay and dry bedding are among the most ignitable materials on an equestrian property. Recommended now: keep them at least 5 feet off structure walls, and farther where practical. Manure is not the fire issue; the dry combustibles are.
Can I keep planters against the house?
Plan on noncombustible pots with well-irrigated, low-fuel plants. Dead or dry container plants against a wall behave like kindling regardless of the pot. This is Recommended now, not required.
