9 rules for unincorporated Lassen County, California.
Verified from official government sources
Unincorporated Lassen County has no fixed lawn-height number in its code. Tall, dry grass and weeds are handled as a public nuisance under County Code Chapter 1.18 and through state defensible-space law (PRC 4291), which directs annual grasses near structures in fire areas to be kept short.
Unincorporated Lassen County does not require a permit to trim trees on private property. The zoning code (Title 18) does require trees near street corners to be limbed up for sight distance, and state defensible-space law (PRC 4291) drives fire-related branch clearance around homes in the State Responsibility Area.
Unincorporated Lassen County has no general ordinance requiring a permit to remove trees from private residential property. Timberland is regulated through the Timber Production Zone (Title 18, Ch. 18.70) and the state Forest Practice Act, and defensible-space removals near homes are allowed and encouraged.
Unincorporated Lassen County controls weeds and hazardous dry vegetation primarily through the Public Nuisances ordinance (County Code Chapter 1.18) and state defensible-space law. The county Agricultural Commissioner and the Lassen Special Weed Action Team also work on noxious-weed control, and PRC 4291 governs fire clearance around homes.
Unincorporated Lassen County does not impose its own day-of-week watering schedule. Outdoor water use is governed by statewide State Water Resources Control Board prohibitions and by each retail water provider. New and rehabilitated permitted landscapes follow California's Model Water Efficient Landscape Ordinance (MWELO).
Capturing rooftop rainwater is legal across California, including unincorporated Lassen County. Under the Rainwater Capture Act of 2012, rooftop rainwater capture needs no state water-right permit, and simple gravity-fed rain barrels generally need no building permit. Larger or pressurized cisterns may require county permits.
Unincorporated Lassen County does not require native or drought-tolerant plantings for homeowners, nor does it ban them. State law (Civil Code 4735) protects a homeowner's right to install low-water and native landscaping, and MWELO encourages climate-appropriate plants for permitted landscapes. Defensible-space rules limit flammable vegetation near homes.
Unincorporated Lassen County has no ordinance banning artificial turf, and the county imposes no special synthetic-turf permit for residential yards. State Civil Code 4735 bars homeowners' associations from prohibiting artificial turf used to replace lawns for water conservation. Installations must still meet drainage and defensible-space rules.
California's SB 1383 requires organic-waste diversion statewide, including unincorporated Lassen County, though rural, low-population, and high-elevation areas may qualify for state waivers. Home backyard composting is encouraged and exempt from collection. Compost piles must not become a nuisance or fire-fuel hazard.
