San Leandro, CA Noise Ordinances: Outdoor Music (2026)

SLMC §4-1-1115 (Prohibited Acts) makes it unlawful to use 'any loud speaker, loudspeaker system, public address or similar device between the hours of 10:00 p.m. and 8:00 a.m. in such a manner as to disturb the peace, quiet and comfort of neighboring residents or persons of normal sensitivity,' with a carve-out for noncommercial public speaking, public assembly, or other permitted activity under Title 4 Chapter 4-20 of the Municipal Code. Separate provisions of §4-1-1115 prohibit band or orchestral concerts during nighttime hours and the use of electronic amplification equipment in City parks during nighttime hours. Daytime amplified outdoor events (block parties, weddings, concerts, fitness classes) require a Noise Exception Permit under SLMC §4-1-1125. Vehicle-mounted amplification is independently regulated by California Vehicle Code §27007 (no sound amplification audible from 50 feet or more outside the vehicle while operating on a highway, except for authorized parades/special events permitted by local authority). The ambient + 5 dB rule of §4-1-1115 always applies as a secondary basis for citation.
