Sonoma County, CA Noise Ordinances: Barking Dogs (2026)

Barking dogs are one area where unincorporated Sonoma County does have a specific, enforceable rule. Under Chapter 5 of the County Code (the Sonoma County Animal Regulation Ordinance), section 5-126 prohibits an animal owner from permitting an animal 'to obstruct the reasonable and comfortable use of property in any neighborhood or community by chasing vehicles, molesting passersby, barking, howling or making other noise.' Any such violation 'is hereby declared to be a public nuisance.' The ordinance sets out how a complaint is handled: when two or more people residing in separate residences (or regularly employed in the neighborhood) affirm in writing that a nuisance exists, the Director must investigate. Where only one person lives or works within 300 feet of the alleged nuisance, that single written affirmation is enough to trigger an investigation. If the investigation confirms a public nuisance, the Director may issue an abatement order to the animal's owner; failure to comply can be referred to the District Attorney for prosecution. The ordinance preserves a neighbor's right to bring a private action under California Civil Code section 3493, and it exempts qualifying agricultural-operation animals protected under Civil Code section 3482.5. Complaints are handled by Sonoma County Animal Services.
