Public Resources Code 4291 requires anyone who owns or occupies a building in the State Responsibility Area to keep 100 feet of defensible space (or to the property line), an ember-resistant zone within 5 feet, and more intensive fuel reduction from 5 to 30 feet. You also have to remove tree limbs within 10 feet of a chimney, keep plants next to the house free of dead wood, and keep the roof clear of leaves and needles. Violations are infractions with $100–$500 fines, and a third conviction within five years is a misdemeanor. Lassen County's Ordinance 2025-03 requires the county fire warden to review limited-density owner-built rural dwelling permits against PRC 4290 and 4291 and County Code Chapter 9.16 (Fire Hazards).

What happens if I don't clear defensible space?
Under PRC 4291.1, a first violation is an infraction with a $100–$500 fine, and a second within five years is $250–$500. A third within five years is a misdemeanor with at least a $500 fine, and CAL FIRE may do the work and bill the owner.
How much defensible space do I need?
100 feet around each structure, or to the property line if that's closer. Do the most intensive fuel reduction within 30 feet and keep an ember-resistant zone within 5 feet. Also remove limbs within 10 feet of chimney outlets and keep the roof free of leaves and needles.
