Summary
San Luis Obispo County abates fire-hazardous weeds and rubbish under County Code Title 16 (Fire Prevention) and California Health and Safety Code Sec. 14875 et seq., authorizing the Fire Code Official to order clearance, enter and abate, and bill costs as a lien on the property.
'Weeds,' as used in this part, includes ... (a) vegetation that bears seeds of a downy or wingy nature; (b) ... not pruned or otherwise neglected so as to attain such large growth as to become, when dry, a fire menace to adjacent improved property; (c) vegetation that is otherwise noxious or dangerous; (d) poison oak and poison ivy ...; (e) dry grass, stubble, brush, litter, or other flammable material which endangers the public safety by creating a fire hazard.
Full Breakdown
County Code Title 16 (Fire Prevention) includes Chapter 16.30, the Abatement of Fire Hazardous Weeds and Rubbish in County Service Area No. 10 - Cayucos, recently amended by Ordinance 3545 to broaden county-wide enforcement authority. Property owners and persons in possession must abate hazardous vegetation or combustible material within thirty days of notice, and the Fire Code Official is authorized 'to enter real property and summarily abate any public nuisance determined to constitute an immediate threat to public health or safety without prior notice or hearing.' Abatement costs may be made a special assessment, added to the county assessment roll, and become a lien on the property under Health and Safety Code Sec.
14875 et seq. Throughout the rest of the unincorporated county, CAL FIRE / SLO County Fire enforces California Public Resources Code Sec. 4291 (defensible space) and the Health and Safety Code weed abatement framework. The County Department of Agriculture / Weights and Measures operates a separate Noxious Weed Management Program targeting state-listed pests (e.g., yellow starthistle, perennial pepperweed) under California Food and Agricultural Code Sec. 5000 et seq.
Violations & Fines
Failure to abate after notice authorizes the County or fire district to perform the work and recover all costs through a special assessment that becomes a lien on the property and is collected with property taxes. Continued non-compliance can lead to additional administrative citations and infraction penalties under PRC Sec. 4291.
