Do Zone 0 Landscaping Rules Apply in Santa Clarita?
Out of the first five feet
- Bark and wood-chip mulch against the foundation. Combustible mulch against the house is an easy place for embers to ignite.
- Dead or dying vegetation of any kind, including dry annuals against the wall after a Santa Clarita summer.
- Firewood and lumber stacks. Store them in Zone 1 or beyond, at least 5 feet off the structure.
- Combustible planters and trellises touching siding, and juniper or italian cypress pressed against the house.
- Stored combustibles: patio cushions, cardboard, brooms, door mats made of natural fiber.
Safer by design
- Gravel, decomposed granite, and pavers. A dry-garden look is a good fit for the first five feet.
- Low, irrigated, high-moisture plants in noncombustible beds, spaced away from vents and windows.
- Hardscape paths and patios ringing the house: they double as the ember break.
- Metal furniture and planters within the zone.
- Well-maintained mature trees whose limbs are kept off the roof and away from chimney outlets. Confirm any removal with the city and LA County Fire first.
Do I have to remove my trees?
We have not identified a Santa Clarita Zone 0 rule that requires tree removal, and no statewide Zone 0 regulation is in force. Existing law does require that branches within 10 feet of a chimney outlet be removed.
The practical, Recommended now approach treats healthy, maintained trees differently from ground fuels: limbs up, dead material out, nothing overhanging the roofline untended.
Before removing any mature tree, confirm with the City of Santa Clarita and LA County Fire. Removal is the last resort, not the default.

What can I plant in the first five feet?
Think low, green, irrigated, and sparse. Low-growing, high-moisture plants in noncombustible beds, with generous spacing from vents, windows, and siding, are the pattern we recommend.
How is the first five feet different from the defensible space I already maintain?
The first five feet is the innermost band. Zone 0 focuses on everything within 5 feet, including mulch, planters, and stored items, not just plants. LA County Fire’s Defensible Space page lists a 100-foot defensible-space radius as a recommendation.
