Defensible space is one of the most important steps you can take to improve your home's chance of surviving a wildfire. Defensible Space is the buffer you create between a structure on your property and the grass, trees, shrubs, and any wildland area that surrounds it. This space is needed to slow or stop the spread of wildfire. It helps protect your home from catching fire from embers, direct flame contact or radiant heat.
The County of San Diego's Defensible Space for Fire Protection Ordinance sets forth various requirements property owners must comply with in order to increase the resilience of their properties.
