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

There is no dedicated vacant-lot maintenance code in the unincorporated county; vacant and absentee-owned parcels are regulated through the same nuisance framework as all property. Under Title 8 (Health and Safety), accumulated garbage, junk, or illegally dumped material on a vacant parcel can be declared a public nuisance and abated by the County with cost recovery (Chapters 8.20 and 8.50). The zoning code reinforces this: Chapter 18.110 (General Development Standards) provides that 'No trash or rubbish shall be allowed to accumulate on any lot or parcel,' and it also limits inoperative/junk vehicles on private property (see the weeds-grass and garage-sale entries). The most significant rural-land duty is wildfire-related. Much of Modoc County lies within a CAL FIRE State Responsibility Area served by the CAL FIRE Lassen-Modoc Unit, and the state Office of the State Fire Marshal publishes Fire Hazard Severity Zone maps for Modoc's SRA. Where a parcel with a structure is in the SRA, California Public Resources Code section 4291 requires the owner to maintain defensible space — generally 100 feet of clearance around buildings (or to the property line) — by removing dead vegetation and combustible debris and keeping grasses low. Truly undeveloped, structure-free lots are managed mainly for fire hazard rather than under a numeric County weed-height rule. Note that large parts of the county are federal land (Modoc National Forest) outside County jurisdiction. Owners should keep lots free of dumped waste and flammable vegetation and confirm current requirements with County code enforcement and CAL FIRE / the local fire district.
