9 rules for unincorporated Lake County, California.
Verified from official government sources
In unincorporated Lake County, the Hazardous Vegetation Abatement Ordinance (County Code Chapter 13, Article VIII, Ord. 3082) requires a 30-foot defensible space around structures and, on unimproved parcels, grass trimmed to under 6 inches within a 10-foot buffer of structures and roads. It supplements California Public Resources Code 4291.
Unincorporated Lake County has no stand-alone urban tree-trimming permit ordinance for private trees. Pruning is governed mainly by the Hazardous Vegetation Abatement Ordinance (trees pruned 6 feet above grade in fire buffers) and the Scenic Combining District. Routine pruning of your own trees generally needs no county permit.
Unincorporated Lake County has no general urban tree-removal permit for individual yard trees. Removal is regulated when it occurs during permitted grading (County Code Ch. 30), on parcels with Scenic (Art. 34) or Environmental Protection (Art. 64) overlays, or as commercial timber harvest, which requires a CAL FIRE Timber Harvesting Plan.
Unincorporated Lake County's Hazardous Vegetation Abatement Ordinance (County Code Chapter 13, Article VIII, Sections 13-57 to 13-66; Ord. 3082, 2019) declares flammable weeds, brush, and combustible material a public nuisance and supplements California PRC 4291. The County Fire Official may abate and bill owners who fail to clear.
Lake County has no single county-wide outdoor watering-day schedule. Conservation is set by the County's Special Districts for its CSA water systems (currently a voluntary 20% reduction, Stage 1), a fixture-retrofit-on-sale ordinance (Ord. 2291), and statewide MWELO requirements administered by Community Development for qualifying new landscapes.
Rainwater harvesting is permitted in unincorporated Lake County. California's Rainwater Capture Act of 2012 (Water Code 10574) allows rooftop capture without a water-right permit, and small non-potable rain barrels are typically permit-exempt under the California Plumbing Code. The County has no ordinance prohibiting rain barrels.
Unincorporated Lake County does not mandate native plants for private gardens. Native and drought-tolerant planting is encouraged through the State MWELO (administered by Community Development) and UC Master Gardener firewise guidance, but homeowners may plant most non-invasive species freely.
Unincorporated Lake County has no ordinance banning residential artificial turf, and California Civil Code 4735 prohibits HOAs from banning synthetic grass on an owner's property. Installation may still require drainage, grading, or building review under County codes when it affects runoff.
California's SB 1383 makes organic-waste recycling mandatory statewide, including unincorporated Lake County: residents and businesses must separate organics or self-haul to a diversion facility. Backyard composting is allowed and encouraged as a diversion method. The County's Health Services / Environmental Health Division administers exemptions.
