Full Breakdown
El Cajon requires defensible space consistent with California Public Resources Code Section 4291, mandating 100 feet of clearance around structures. Zone 1 (0-35 feet) requires removal of all flammable vegetation. Zone 2 (35-100 feet) requires thinning. Annual grass must be kept to 4 inches maximum. Heartland Fire & Rescue serves El Cajon and enforces brush management regulations through annual inspections. The East County valley climate with hot summers (regularly exceeding 100 degrees F), low humidity, and Santa Ana wind exposure creates critical fire risk. Properties on hillsides and near canyon areas require particular attention. Tree branches must be cleared at least 6 feet from the ground. Wood piles must have 10 feet of clearance to bare mineral soil.
Violations & Fines
Failure to maintain defensible space results in citation and forced abatement at owner's expense. Non-compliance may void fire insurance.
