Summary
Corona property owners must maintain 100 feet of defensible space around structures under California Public Resources Code §4291, enforced locally by Riverside County Fire Department/CAL FIRE. Corona's Skyline Drive, Sierra Del Oro, and southern hillside properties are subject to annual inspection programs.
(a) A person who owns, leases, controls, operates, or maintains a building or structure in the state responsibility area shall at all times do all of the following:
(1) (A) Maintain defensible space of 100 feet from each side and from the front and rear of the structure, but not beyond the property line, except as provided in subparagraph (B). The amount of fuel modification necessary shall consider the flammability of the structure as affected by building material, building standards, location, and type of vegetation. Fuels shall be maintained and spaced in a condition so that a wildfire would be unlikely to ignite the structure. This subparagraph does not apply to single specimens of trees or other vegetation that are well-pruned and maintained so as to effectively manage fuels and not form a means of rapidly transmitting fire from other nearby vegetation to a structure or from a structure to other nearby vegetation or to interrupt the advance of embers toward a structure. The intensity of fuels management may vary within the 100-foot perimeter of the structure, with more intense fuel reductions being utilized between 5 and 30 feet around the structure, and an ember-resistant zone being required within 5 feet of the structure, based on regulations promulgated by the board, in consultation with the department, to consider the elimination of materials in the ember-resistant zone that would likely be ignited by embers.
(2) Remove that portion of a tree that extends within 10 feet of the outlet of a chimney or stovepipe.
(3) Maintain a tree, shrub, or other plant adjacent to or overhanging a building free of dead or dying wood.
(4) Maintain the roof of a structure free of leaves, needles, or other vegetative materials.
Full Breakdown
20 in coordination with Riverside County Fire/CAL FIRE, applying California's statewide 100-foot defensible space rule from Public Resources Code §4291 to all parcels within or adjacent to State Responsibility Areas (SRA) and Local Responsibility Area Very High Fire Hazard Severity Zones (LRA-VHFHSZ). Defensible space is divided into Zone 0 (0-5 feet ember-resistant zone added under AB 3074, regulations finalizing 2025), Zone 1 (5-30 feet 'lean, clean and green'), and Zone 2 (30-100 feet reduced fuel zone with grass mowed to 4 inches and limbs trimmed).
Hillside Corona neighborhoods including Skyline Drive, the Sierra Del Oro/Coronita corridor, and parcels backing onto Cleveland National Forest receive annual notice-and-inspection cycles each spring before fire season. Notices typically allow 30 days for owner abatement before the city engages a contractor for forced abatement at owner expense plus administrative fees, with costs recorded as a special assessment against the property tax roll if unpaid. 20.
