Defensible Space

Zones 0, 1, and 2 around your home

California requires 100 feet of defensible space around structures in California's high-risk areas. The zones are cumulative: the closer to the house, the stricter the standard.

Zone 0
0–5 feet
  • Remove all dead plants, leaves, and pine needles from the ground and roof
  • No bark mulch, wood chips, or combustible ground cover — use gravel, pavers, or bare soil
  • Move firewood, propane tanks, and stored lumber at least 30 feet away
  • Relocate potted plants and door mats made of combustible material
  • Trim any branch overhanging the roof or within 10 feet of the chimney
Zone 1
5–30 feet
  • Keep grass mowed to four inches or less through fire season
  • Remove ladder fuels — clear brush growing under trees
  • Space shrubs so fire cannot carry from one to the next
  • Limb trees up 6 to 10 feet from the ground
  • Clear dead vegetation and keep landscaping irrigated where possible
Zone 2
30–100 feet
  • Thin trees so canopies are separated by at least 10 feet on level ground, more on slopes
  • Cut annual grass down to a maximum height of four inches
  • Remove fallen leaves, needles, and small branches to a depth of three inches
  • Stack downed material for the community chipping day rather than burning it
  • Keep exposed woodpiles clear of surrounding vegetation by 10 feet

Maintenance calendar

  • Late winter

    Plan the year, book a chipping slot, order materials while contractors are available.

  • Spring

    Cut grass before it cures, limb up trees, clear winter storm debris. Firewise Day falls here.

  • Early summer

    Final Zone 0 sweep before fire season. Clean gutters and roof valleys again.

  • Fire season

    Weekly needle and leaf removal from roof, gutters, and Zone 0. Keep go-bags current.

  • Fall

    Post-season cleanup, chip piles removed, note what to fix before next year.

Chipping program

Stack cut material butt-end toward the road, no piece thicker than eight inches, within ten feet of the roadway edge and clear of overhead lines. Sign up for a chipping date on the events page — the program is funded through the Fire Safe Council and is free to residents.
