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

In all-unincorporated Trinity County there is no dedicated vacant-lot code; vacant and absentee-owned parcels are regulated through the same nuisance framework as all property. Under Title 8 (Health, Safety and Nuisances), Chapter 8.08, it is unlawful to dump or accumulate solid or hazardous waste on any public or private property, including vacant land, and accumulated garbage, junk, or illegally dumped material on a vacant parcel can be abated by the County as a nuisance with cost recovery. The most significant maintenance duty on rural land is wildfire-related: Trinity County lies almost entirely within a CAL FIRE State Responsibility Area, so California Public Resources Code section 4291 requires owners of parcels with structures to maintain defensible space — generally 100 feet of vegetation clearance around buildings (or to the property line), with the most intensive clearing nearest the structure. Annual grasses must be kept low (CAL FIRE guidance sets a maximum height of about four inches for dead/dying grass), dead vegetation removed, and combustible debris cleared. Truly undeveloped, structure-free lots are managed primarily for fire hazard through CAL FIRE rather than a numeric County weed-height rule. The County's blight enforcement (being strengthened in 2025) also targets unsafe abandoned structures on neglected parcels. Owners should keep lots free of dumped waste, junk vehicles, and flammable vegetation, and confirm current requirements with County code enforcement and the local CAL FIRE / fire district.
