Defensible Space & Weed Abatement in San Mateo
Bring your property up to CAL FIRE standard — and keep your insurance.
Wildfire fuel reduction to CAL FIRE's defensible-space standards. California's PRC 4291 requires 100 feet of defensible space around structures in wildland areas — we clear and limb to those Zone 0, 1, and 2 specs. Across San Mateo County — from Redwood City, San Mateo, Half Moon Bay, and Woodside — most of the work sits in the rural estate belt — Woodside, Portola Valley, and the coastal hills — where large wooded parcels need defensible space, brush clearing, driveways, and site prep.

Local context
Why San Mateo landowners need defensible space
The wooded coastal hills above Woodside and Portola Valley sit in the wildland-urban interface, and large estate lots backing onto open space and redwood canyon drive defensible-space and fuel-reduction needs.

Common questions
Defensible Space & Weed Abatement FAQs
How much defensible space does California require?+
Public Resources Code 4291 requires 100 feet of defensible space around structures in State Responsibility Areas and most wildland zones — or to your property line if it's closer. That 100 feet is split into Zone 0 (0–5 ft, ember-resistant), Zone 1 (5–30 ft, lean/clean/green), and Zone 2 (30–100 ft, reduced fuel).
Why is my insurer asking for this?+
After repeated catastrophic wildfire seasons, many carriers now condition renewal in the Bay Area WUI on documented defensible space, and some have non-renewed policies outright in high-risk areas. Bringing your property to PRC 4291 standard — and keeping photos and an invoice — is increasingly what it takes to stay insurable.
What does Zone 0 actually mean?+
Zone 0 is the critical 0–5 feet right around your home, and it should be ember-resistant: no combustible bark mulch, no firewood stacks, no flammable shrubs touching the siding, and ideally hardscape or bare mineral soil. Embers landing in this zone are the leading way homes ignite, so it gets the strictest treatment.
What will it cost for my place?+
A typical one-acre home runs roughly $1,000–$4,000 for full 100-foot defensible space. Crews often price by the hour ($100–$250) or by the acre for Zone 2 brush ($100–$500+). Steep terrain, heavy fuel loads, and lots of close-in hand work around structures push costs up.
Can a machine do all of it?+
Not the close-in zones. A mulcher is ideal for thinning Zone 2 brush quickly, but Zone 0 and Zone 1 around the house, decks, fences, and landscaping need careful hand work to protect structures and keepers. The best results come from combining both.
