Sonoma County, CA Noise Ordinances: Leaf Blower Rules (2026)

There is no Sonoma County ordinance that bans gas-powered leaf blowers, sets leaf-blower hours, or imposes leaf-blower decibel limits in the unincorporated communities. The County's General Plan Noise Element noted that a future noise-control ordinance 'may exempt or modify noise requirements for ... property maintenance' activities, which would include yard equipment, but no such comprehensive ordinance has been adopted. As a result, routine daytime leaf-blower use by homeowners and landscapers is generally not separately regulated by the County. Where leaf-blower noise becomes a genuine, persistent disturbance, the applicable tools are the General Plan Noise Element's exterior performance standards (Table NE-2) — which can be relevant to commercial landscaping operations reviewed through permits — and California Penal Code section 415, which the Sheriff can enforce against loud and unreasonable noise. It is also worth noting that, separate from any local noise rule, the California Air Resources Board has restricted the sale of new gas-powered small off-road engines (which include many leaf blowers) statewide; that is an emissions and equipment-sales regulation, not a Sonoma County noise ordinance. Residents bothered by neighbor or landscaper leaf-blower noise generally have the best results by communicating directly and, if needed, raising a nuisance complaint.
