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.
Defensible space is the buffer of treated vegetation around a home that gives it — and firefighters — a fighting chance during a wildfire. In California, Public Resources Code 4291 legally requires 100 feet of defensible space around structures in State Responsibility Areas and many wildland-urban interface zones. Meeting that standard is no longer just smart; in much of the Bay Area it's the difference between keeping and losing your home insurance.
The work is organized into three zones. Zone 0, the ember-resistant 0–5 feet immediately around the house, should be kept clear of anything combustible — no bark mulch, no woodpiles, no shrubs against siding. Zone 1, from 5 to 30 feet, is the 'lean, clean, and green' zone: remove dead plants, prune up tree limbs, and break up continuous fuels. Zone 2, from 30 to 100 feet, is the reduced-fuel zone where you thin brush, mow grass, and create horizontal and vertical spacing between plants so fire can't ladder up or run.
Demand for this work has surged across the Bay Area's WUI as insurers non-renew policies in high-risk areas and counties step up inspections. A skid-steer with a mulching head can knock out Zone 2 brush far faster than hand crews, while careful hand work handles the close-in zones around structures, fences, and landscaping.
How It Works
The Defensible Space process
- 1
Risk & zone assessment
We map your structure's 0–5 ft, 5–30 ft, and 30–100 ft zones against PRC 4291 and any insurer or county requirements.
- 2
Zone 0 & 1 close-in work
Hand crews clear the ember-resistant zone, remove dead material, limb up trees, and break ladder fuels near the home.
- 3
Zone 2 fuel reduction
A mulching machine thins and spaces brush across the outer 30–100 ft far faster than hand labor, leaving mulch in place.
- 4
Compliance walk-through
We walk the finished clearance with you against the standard so you're ready for inspection or insurance documentation.

FAQ
Defensible Space questions, answered
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.
