Glenn County, CA Noise Ordinances: Quiet Hours (2026)

Glenn County's primary quiet-hours rule sits in Chapter 10.25 of the Glenn County Code, added by Ordinance 1322 (adopted by the Board of Supervisors on January 24, 2023). Section 10.25.020 makes it unlawful, between 10:00 p.m. and 7:00 a.m. (and not until 11:00 p.m. on Friday and Saturday), to use or permit any audio equipment 'in such a manner as to disturb the peace, quiet and comfort of neighboring residential inhabitants.' The county adopted this targeted ordinance specifically because California Penal Code section 415(2) requires a complaining party other than the responding officer, leaving deputies few options when neighbors would not file a formal complaint. The ordinance applies in unincorporated communities such as Hamilton City, Artois, Elk Creek, Butte City, Bayliss, Glenn, and Ord Bend; the incorporated cities of Willows and Orland enforce their own municipal codes. Separately, the zoning code's noise performance standard, Section 15.56.100, sets lower one-hour equivalent sound-pressure limits at night: 45 dBA for property received in residential and resource districts, 55 dBA for commercial, and 60 dBA for industrial between 10:00 p.m. and 7:00 a.m. Together these give Glenn County both a plain-audibility test for amplified sound and numeric dBA limits during overnight hours.
