Listed here are several suggestions that you can implement immediately. Others need to be considered at
the time of construction or remodeling. You should also contact your local fire department, forestry office,
emergency management office or building department for information about local fire laws, building codes and
protection measures. Obtain local building codes and weed abatement ordinances for structures built near
Find Out What Your Fire Risk Is
Learn about the history of wildfire in your area. Be aware of recent weather. A long period without rain
increases the risk of wildfire. Consider having a professional inspect your property and offer recommendations
for reducing the wildfire risk. Determine your community's ability to respond to wildfire. Are roads
leading to your property clearly marked? Are the roads wide enough to allow firefighting equipment to get
through? Is your house number visible from the roadside?
Learn and teach safe fire practices.
- Build fires away from nearby trees or bushes.
- Always have a way to extinguish the fire quickly and completely.
- Install smoke detectors on every level of your home and near sleeping areas.
- Never leave a fire--even a cigarette--burning unattended.
- Avoid open burning completely, and especially during dry season.
Always be ready for an emergency evacuation.
Evacuation may be the only way to protect your family in a wildfire. Know where to go and what to
bring with you. You should plan several escape routes in case roads are blocked by a wildfire.
Create Safety Zones Around Your Home
All vegetation is fuel for a wildfire, though some trees and shrubs are more flammable than others. To
reduce the risk, you will need to modify or eliminate brush, trees and other vegetation near your home.
The greater the distance is between your home and the vegetation, the greater the protection.
Create a 30-foot safety zone around the house.
Keep the volume of vegetation in this zone to a minimum. If you live on a hill, extend the zone on
the downhill side. Fire spreads rapidly uphill. The steeper the slope, the more open space you will need
to protect your home. Swimming pools and patios can be a safety zone and stone walls can act as heat shields
and deflect flames. In this zone, you should also do the following:
- Remove vines from the walls of the house.
- Move shrubs and other landscaping away from the sides of the house.
- Prune branches and shrubs within 15 feet of chimneys and stove pipes.
- Remove tree limbs within 15 feet of the ground.
- Thin a 15-foot space between tree crowns.
- Replace highly flammable vegetation such as pine, eucalyptus, junipers and fir trees with lower growing,
less flammable species. Check with your local fire department or garden store for suggestions.
- Replace vegetation that has living or dead branches from the ground-level up (these act as ladder fuels
for the approaching fire).
- Cut the lawn often keeping the grass at a maximum of 2 inches. Watch grass and other vegetation near the
driveway, a source of ignition from automobile exhaust systems.
- Clear the area of leaves, brush, evergreen cones, dead limbs and fallen trees.
Create a second zone at least 100 feet around the house.
This zone should begin about 30 feet from the house and extend to at least 100 feet. In this zone, reduce or
replace as much of the most flammable vegetation as possible. If you live on a hill, you may need to extend
the zone for several hundred feet to provide the desired level of safety.
Clear all combustibles within 30 feet of any structure.
- Install electrical lines underground, if possible
- Ask the power company to clear branches from power lines.
- Avoid using bark and wood chip mulch
- Stack firewood 100 feet away and uphill from any structure.
- Store combustible or flammable materials in approved safety containers and keep them away from the house.
- Keep the gas grill and propane tank at least 15 feet from any structure. Clear an area 15 feet around
the grill. Place a 1/4 inch mesh screen over the grill. Always use the grill cautiously but
refrain from using it all during high risk times.
Protect Your Home
Remove debris from under sun decks and porches.
Any porch, balcony or overhang with exposed space underneath is fuel for an approaching fire.
Overhangs ignite easily by flying embers and by the heat and fire that get trapped underneath. If
vegetation is allowed to grow underneath or if the space is used for storage, the hazard is increased
significantly. Clear leaves, trash and other combustible materials away from underneath sun decks and
porches. Extend 1/2-inch mesh screen from all overhangs down to the ground. Enclose wooden stilts with
non-combustible material such as concrete, brick, rock, stucco or metal. Use non-combustible patio
furniture and covers. If you're planning a porch or sun deck, use non-combustible or fire-resistant
materials. If possible, build the structure to the ground so that there is no space underneath.
Enclose eaves and overhangs.
Like porches and balconies, eaves trap the heat rising along the exterior siding. Enclose all eaves
to reduce the hazard.
Cover house vents with wire mesh
Any attic vent, soffit vent, louver or other opening can allow embers and flaming debris to enter a
home and ignite it. Cover all openings with 1/4 inch or smaller corrosion-resistant wire mesh. If you're
designing louvers, place them in the vertical wall rather than the soffit of the overhang.
Install spark arrestors in chimneys and stovepipes.
Chimneys create a hazard when embers escape through the top. To prevent this, install
spark arrestors on all chimneys, stovepipes and vents for fuel-burning heaters. Use spark
arrestors made of 12-gauge welded or woven wire mesh screen with openings 1/2 inch across.
Ask your fire department for exact specifications. If you're building a chimney, use non-combustible
materials and make sure the top of the chimney is at least two feet higher than any obstruction within
10 feet of the chimney. Keep the chimney clean.
Use fire resistant siding.
Use fire resistant materials in the siding of your home, such as stucco, metal, brick, cement shingles,
concrete and rock. You can treat wood siding with UL-approved fire retardant chemicals, but the
treatment and protection are not permanent.
Choose safety glass for windows and sliding glass doors.
Windows allow radiated heat to pass through and ignite combustible materials inside. The larger the
pane of glass, the more vulnerable it is to fire. Dual- or triple-pane thermal glass, and fire resistant
shutters or drapes, help reduce the wildfire risk. You can also install non-combustible awnings to shield
windows and use shatter-resistant glazing such as tempered or wireglass.
Prepare for water storage: develop an external water supply such as a small pond, well or pool.
Other safety measures to consider at the time of construction or remodeling.
What to do before a wildfire
What to do during a wildfire
- Choose locations wisely; canyon and slope locations increase the risk of exposure to woodland fires.
- Use fire-resistant materials when building, renovating, or retrofitting structures.
- Avoid designs that include wooden decks and patios.
- Use non-combustible materials for the roof.
- The roof is especially vulnerable in a wildfire. Embers and flaming debris can travel great distances, land on your
roof and start a new fire. Avoid flammable roofing materials such as wood, shake and shingle. Materials that are more fire resistant include single ply membranes, fiberglass shingles, slate, metal, clay and concrete tile. Clear gutters of leaves and debris.
