Sutter County, CA Noise Ordinances: Amplified Music & Events (2026)

Unincorporated Sutter County does not have a broad amplified-music ordinance covering house parties, backyard speakers, or commercial venues. The one piece of county code that directly governs amplified sound is Chapter 200, "Sound Trucks," in the Sutter County Code of Ordinances (Municode), which applies to sound-amplifying equipment mounted on or used from vehicles in the unincorporated area. Under that chapter, non-commercial sound-truck use is limited to music or human speech, the content may not be profane, lewd, indecent, or slanderous, and the volume must be controlled so it is not audible beyond 100 feet from the truck and is not unreasonably loud, raucous, jarring, or a nuisance; equipment may not exceed 15 watts of power in the last stage of amplification. Commercial-advertising use of a sound truck requires a license from the County Clerk. For amplified music that is not from a sound truck — a loud party or sound system at a residence — there is no county ordinance with decibel limits, because the county has not adopted a general noise ordinance. Those situations are handled as disturbing the peace under California Penal Code 415, which covers loud and unreasonable noise that maliciously and willfully disturbs others, enforced by the Sutter County Sheriff.
