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

Outdoor music in unincorporated Stanislaus County is governed by the same provisions that cover amplified sound. Section 10.46.060(D) of the Noise Control Ordinance (Chapter 10.46) provides that no person shall install, use, or operate sound-amplifying equipment, or perform or allow live music, unless the resulting sound is not audible to the human ear more than 200 feet away. This 200-foot audibility test applies to outdoor performances at homes, ranches, venues, and events. In addition, Section 10.46.050 requires the general Table A exterior limits to be reduced by 5 dB(A) where the noise consists primarily of music or speech, so an outdoor band or DJ is held to a stricter measured standard than ordinary background noise. Audio equipment more generally (such as outdoor speakers) may not be audible inside a neighbor's dwelling between 10:00 p.m. and 7:00 a.m. (Section 10.46.060(C)). Parades, fireworks displays, and other special events that obtain a county permit are exempt under Section 10.46.080, provided they comply with all conditions written on the permit. Where the 200-foot rule conflicts with a land use permit's conditions of approval, the ordinance states the 200-foot requirement controls. The Sheriff's Department enforces these rules (Section 10.46.100).
