Twain Harte, CA Noise Ordinances: Leaf Blower Rules (2026)

Some California cities and counties restrict leaf blowers by limiting their hours of use, capping their noise output, or banning gas-powered models outright. Unincorporated Tuolumne County has adopted no such rule. The county's FAQ confirms there is no general noise ordinance covering the unincorporated area, and there is no separate leaf-blower or yard-equipment provision in the county code that this research identified. Practically, routine daytime use of a leaf blower or other landscaping equipment on private property is not regulated by the county and is not a violation of any local noise standard. The only avenue available is California's general law: if equipment noise is willful, loud and unreasonable and actually disturbs another person, the Sheriff could cite disturbing the peace under California Penal Code section 415, and chronic noise could in principle support a private nuisance claim under California Civil Code section 3479. Separately, California's statewide shift away from gas-powered small off-road engines is driven by state air-quality regulation (administered by the California Air Resources Board), not by any Tuolumne County noise rule. Residents seeking limits beyond state law would need the county to adopt a noise ordinance, which as of the latest reporting it had not done.
