What Is A Fire Defensible Space Created Around A Home?

A defensible space is the area completely surrounding a home and extending 100 feet out from the home. That space is divided into two “zones”, Zone 1 encircles the entire area around any buildings, structures, decks, etc., for a distance of 30 feet, and Zone 2 encircles Zone 1, extending the remaining 100 feet distance away from the homes. There are specific requirements for what elements can be in Zone 1 and Zone 2, as well as what must be removed. This is the breakdown of what a good “defensible space” would be:
ZONE 1
• Zone 1 extends 30 feet* out from buildings, structures, decks, etc.
• Trim trees regularly to keep branches a minimum of 10 feet from other trees.
• Remove branches that hang over your roof and keep dead branches 10 feet away from your chimney.
• Remove or prune flammable plants and shrubs near windows.
• Remove all dead plants, grass and weeds.
• Remove dead or dry leaves and pine needles from your yard, roof and rain gutters.
• Relocate wood piles into Zone 2.
• Remove vegetation and items that could catch fire from around and under decks.
• Create a separation between trees, shrubs and items that could catch fire, such as patio furniture, wood piles, swing sets, etc.

ZONE 2
• Cut or mow annual grass down to a maximum height of 4 inches.
• Create horizontal spacing between shrubs and trees: make sure there is extra clearance between trees and bushes that are in close proximity to each other.
• Create vertical spacing between grass, shrubs and trees:
• remove all tree branches that are lower than 6 feet from the ground.; trim shrubs and trees so that there is extra clearance between the tops of shrubs and the bottom of the lowest tree branches
• Remove fallen leaves, needles, twigs, bark, cones, and small branches.
