Lake County, CA Property Maintenance: Vacant Lot Maintenance (2026)

8 defines an unimproved parcel as any real property, regardless of size, on which no structure is located. 3, the duty to abate hazardous vegetation on an unimproved parcel requires removing flammable vegetation and combustible growth within thirty feet of neighboring structures and roadway frontage, removing dead and dying vegetation in that same thirty-foot zone, trimming grass and combustible surface vegetation within ten feet of neighboring structures or road frontage to less than six inches in height unless it is needed for erosion control, and pruning trees within ten feet of neighboring structures or frontage to at least six feet above grade.

5 exempts a commercial agricultural crop actively grown and managed by the property owner or tenant from the definition of hazardous vegetation. As with improved parcels, the County Fire Official may require additional defensible space out to one hundred feet based on slope, fuel load, and fuel type, and may authorize alternatives to disking or mowing where terrain makes standard clearing impractical. The County Fire Official may also summarily abate an immediate threat to public health or safety without prior notice or hearing under Health and Safety Code Section 14930 and Government Code Section 25845.

Separately, Chapter 13's general nuisance definition in Section 13-3(e)(7) already treats the accumulation of weeds and rubbish on any real property, improved or not, as a nuisance subject to abatement.
