Lassen County, CA Noise Ordinances: Outdoor Music (2026)

There is no separate 'outdoor concert' chapter in the Lassen County Code; outdoor and event music is regulated through the general Noise Ordinance, Chapter 9.65. Section 9.65.040 makes it a public nuisance to exceed the one-hour average sound-level limits in Table 1 at the property line - 65 dBA (7 a.m.-7 p.m.), 60 dBA (7 p.m.-10 p.m.) and 55 dBA (10 p.m.-7 a.m.) for residential property. Section 9.65.050 separately declares it a prohibited act to play a radio, instrument, stereo, loudspeaker or amplifier that exceeds the Section 9.65.040 levels (including when measured 25 feet from a device in a public right-of-way), or to use amplifiers for commercial advertising over public property. For organized or temporary events with amplified sound, the Noise Element's Action 1.1b directs the county to enforce temporary-event permit noise standards (referenced to Section 9.65.070(a)(3)) and to set conditions such as hours of operation, speaker orientation and amplifier placement through the use-permit or license. Discretionary projects that may exceed the standards can be required to submit a noise study.
