Napa County Code Chapter 8.36 (Fire Protection — Fire Hazard Abatement) requires property owners to clear weeds, dry grass, brush, dead trees, and rubbish that constitute a fire hazard. The Napa County Fire Marshal conducts annual inspections, issues abatement notices, and may have nuisance vegetation removed at the owner's expense under §8.36.100.
Chapter 8.36 of the Napa County Code, re-enacted as Ordinance 1467, governs weed and rubbish abatement on a fire-hazard basis. The chapter defines 'combustible vegetation' as material that in its natural state will readily ignite, burn, and transmit fire — including dry grass, brush, weeds, dead or dying trees, leaf litter, and other flammable materials. Property owners must clear or treat this vegetation within 100 feet of any structure and along driveways and access roads. The Fire Marshal conducts annual inspections beginning in late spring; first contact is typically a notice of violation with a compliance deadline. If the owner does not comply by the deadline (and any timely appeal is denied by the fire chief), the County may declare a public nuisance and contract removal under §8.36.100. All costs — including administrative expenses — are charged to the parcel owner and may be recorded as a lien if unpaid. Adjacent property owners share responsibility when a neighboring structure is within 100 feet of the property line.
Failure to abate after notice is a violation of Chapter 8.36 and triggers County-led abatement at the owner's expense. Costs are billed to the parcel owner and unpaid amounts become a lien on the property. The Fire Marshal may also issue administrative citations. Cost-recovery applies even if the violation results from neglected weeds rather than active misconduct.
