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

Two parts of the Mono County Code address barking dogs in the unincorporated communities. Section 9.36.030 (Noisy dogs), in the Title 9 Animals code adopted by Ordinance No. 21-01 in 2021, states that it is unlawful for any person to permit a dog in his possession or under his control to habitually destroy the peace and quiet of any person or neighborhood by habitual barking or howling. Animal Services enforces this provision; where a barking nuisance affects multiple residents, neighbors can file a petition and an officer can issue the owner a citation for a public-nuisance violation. Separately, the Noise Regulation in Section 10.16.070(B)(4) prohibits owning, possessing or harboring any animal or bird that, frequently or for continued duration, generates sounds that create a noise disturbance across a residential or commercial real property line. A noise disturbance is defined as a sound exceeding the background level by 10 dBA during the day or 5 dBA at night. Because Mono County is rural Eastern Sierra terrain, the focus is on habitual barking that disturbs the neighborhood rather than a fixed decibel cap for a single bark. These animal rules apply only in the unincorporated areas, not the Town of Mammoth Lakes.
