Why 100 Feet ? Following these simple steps can dramatically increase the
chance of your home surviving a wildfire!
A Defensible Space of 100 feet around your home is
required by law.(1) The goal is to protect your home while
providing a safe area for firefighters.
“Lean, Clean and Green Zone.”
- Clearing an area of 30 feet immediately
surrounding your home is critical. This area
requires the greatest reduction in flammable
“Reduced Fuel Zone.”
- The fuel reduction zone in the remaining
70 feet (or to property line) will depend on
the steepness of your property and the
Spacing between plants improves the chance
of stopping a wildfire before it destroys your
home. You have two options in this area:
Create horizontal and vertical spacing
between plants. The amount of space will
depend on how steep the slope is and the
size of the plants.
Large trees do not have to be cut and
removed as long as all of the plants
beneath them are removed. This
eliminates a vertical “fire ladder.”
When clearing vegetation, use care when
operating equipment such as lawnmowers.
One small spark may start a fire; a string
trimmer is much safer.
Remove all buildup of needles and leaves
from your roof and gutters. Keep tree limbs
trimmed at least 10 feet from any chimneys
and remove dead limbs that hang over your
home or garage. The law also requires a
screen over your chimney outlet of not more
than ½ inch mesh.
(1) These regulations affect most of the grass, brush, and
timber-covered private lands in the State. Some fire department
jurisdictions may have additional requirements. Some
activities may require permits for tree removal. Also, some
activities may require special procedures for, 1) threatened and
endangered species, 2) avoiding erosion, and 3) protection of
water quality. Check with local officials if in doubt. Current
regulations allow an insurance company to require additional
clearance. The area to be treated does not extend beyond your
property. The State Board of Forestry and Fire Protection has
approved Guidelines to assist you in complying with the new
law. Contact your local CDF office for more details.
