Livermore, CA Noise Ordinances: Barking Dogs (2026)

060(A) targets chronic barking directly: it is unlawful and a nuisance for the owner of any animal to knowingly permit that animal, by barking or other noise, to disturb any other person's peace and quiet. The ordinance does not stop at a single bark; it requires the owner to take immediate steps to quiet the animal every time it creates a disturbance, and separately bars leaving the animal unattended in a spot where its barking, if prolonged or repeated an undue number of times, disturbs a neighbor.

The same section, in subsections B and C, folds in related nuisance conduct: letting an animal damage or destroy another person's or public property, repeatedly depositing waste on that property, or letting the animal molest, attack or chase people, vehicles or other domestic animals. 040 lets the officer inspect a property on reasonable cause after presenting credentials and demanding entry. Because the barking-dog rule is written as a nuisance standard rather than a decibel or time-of-day limit, an officer or a complaining neighbor must show the noise was prolonged or repeated enough, and disturbed someone's peace and quiet, rather than pointing to a fixed numeric threshold. The ordinance applies citywide to every animal owner, not only dog owners, and the section itself dates to the original 1987 codification (Ord. 1244).
