Summary
State law folded into Palmdale's fire-prone development rules requires owners to maintain 100 feet of defensible space around every building, with intensified fuel reduction between 5 and 30 feet and an ember-resistant zone within 5 feet. Los Angeles County Fire, which serves as Palmdale's Fire Department, administers the standard citywide.
(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. ... 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.
Full Breakdown
Public Resources Code Section 4291 obligates anyone who owns, leases, controls, operates or maintains a building in a state responsibility area to maintain defensible space of 100 feet from each side, front and rear of the structure, though never beyond the property line. A greater distance can be imposed by local ordinance or, for insured dwellings, by an insurer's fire expert, but any fuel modification beyond the property line requires the adjacent owner's written consent. Owners must also remove any tree limb within 10 feet of a chimney or stovepipe outlet, keep trees and shrubs near a building free of dead or dying wood, and keep the roof clear of leaves, needles and other vegetative debris.
Before building or rebuilding a fire-damaged structure requiring a permit, the owner must obtain the local building official's certification of compliance and, after completion, a final inspection report, both of which must be furnished to the insurer on request. The State Fire Marshal may exempt structures built entirely of nonflammable exterior materials, but only once the occupant consents in writing to an interior inspection verifying compliance. 090(A)(1)(l) requires every landscape design plan for a fire-prone project to provide a defensible space or zone around the building per Public Resources Code Section 4291(a) and (b) and to avoid fire-prone plant materials and highly flammable mulches. 400, incorporating Los Angeles County Fire Code Title 32) governs Wildland-Urban Interface construction in those zones.
Violations & Fines
If defensible space is not maintained, the State Fire Marshal may authorize removal of noncompliant vegetation and charge the cost as a lien against the property under Government Code Section 51186. Owners must be notified of new requirements, such as the ember-resistant zone added by Assembly Bill 3074, before penalties attach. Los Angeles County Fire District, defined as Palmdale's Fire Department, enforces defensible space citywide; general code violations carry PMC Chapter 1.12 misdemeanor exposure up to a $1,000 fine and six months in jail, or infraction fines to $500.
