San Leandro, CA Noise Ordinances: Amplified Music & Events (2026)

San Leandro treats amplified sound more strictly than ordinary stereos. §4-1-1115(d) (Loud Music in Parks) makes it unlawful to use any amplifier, radio loudspeaker, phonograph, tape amplifier, electronically operated or acoustic musical instrument, or similar device for producing sound on any public street, park, grounds, or open area to which the public has access (publicly OR privately owned) between 10:00 p.m. and 9:00 a.m. - an 11-hour blackout. Outside those hours, the equipment still may not be used in a manner that disturbs neighbors or persons of normal sensitivity. §4-1-1115(e)(2) extends this to band, orchestral concerts, rehearsals, or practice between 10:00 p.m. and 8:00 a.m. §4-1-1115(e)(3) prohibits any loudspeaker, public address, or similar device between 10:00 p.m. and 8:00 a.m. anywhere if it disturbs neighbors. Permitted special events under Chapter 4-20 of the Municipal Code are exempt, as are school athletic events, school bands, and outdoor entertainment events conducted between 7:00 a.m. and 10:00 p.m. (§4-1-1120(b)). If immediate compliance is impractical, applicants may seek up to a 6-month exception permit from the City Manager under §4-1-1125.
