Riverside, CA Noise Ordinances: Outdoor Music (2026)

Riverside's outdoor-music rules are layered. §7.35.010(B)(1) makes it unlawful to play any radio, audio equipment, drum, or musical instrument in a manner that disturbs neighbors of normal sensitivity; between 10 p.m. and 7 a.m., audibility at 50 feet from the source is prima facie evidence of violation. §7.35.010(B)(2) restricts loudspeakers and PA systems: between 10 p.m. and 7 a.m., they may not create a noise disturbance across a residential property line, and at any time may not exceed the underlying land-use decibel cap (55 dBA residential day / 45 dBA night). The 'plainly audible' test under §7.35.010(B)(11)(c)–(d) sets a 50-ft daytime threshold (7 a.m.–10 p.m.) and a tighter 25-ft nighttime threshold (10 p.m.–7 a.m.) measured in any direction from the music/sound source. Non-commercial public speaking, public assembly, school events, and 'occasional public and private gatherings' between 7 a.m. and 10 p.m. are exempt under §7.35.020(B). Variances for outdoor concerts/events are issued by the Zoning Administrator under §7.40.010 (one-year max, 300-foot notice).
