Grass Valley, CA Noise Ordinances: Outdoor Music (2026)

The County of Nevada (California) regulates outdoor music primarily through land-use approvals rather than a stand-alone music ordinance. Outdoor special-event venues in rural districts are allowed subject to approval of a Use Permit, and the County administers an Outdoor Event Application process. In County special-event approvals reviewed through CEQA, conditions have included 'no amplified music after 10 p.m.,' restricting late-night amplified sound even where the event itself may run later. Outdoor music must also comply with the County's exterior noise standards under the General Plan Noise Element (Chapter 9) and zoning Section L-II 4.1.7, which cap exterior noise by zoning district and time of day (for instance, residential daytime 55 dBA Leq dropping to 45 dBA Leq overnight). The General Plan further allows the County to apply a more restrictive standard where the noise contains music or speech. Some smaller gatherings sponsored by qualifying nonprofit organizations may be exempt from the outdoor event permit under specific conditions. For non-event outdoor music that disturbs neighbors, the County directs complaints to the Sheriff (530-265-1471) under California Penal Code Section 415.
