Corona, CA Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Section 9.24.020 makes it unlawful for anyone other than law enforcement or a government agency to install, use or operate a loudspeaker or amplifying device, fixed or vehicle-mounted, on any city street without a Chief of Police permit. The Chief must issue the permit unless the equipment's placement or condition would create a clear danger to public safety, and cannot factor in the content of the message being amplified; a denial must come with written reasons, and §9.24.030 gives the applicant two business days to appeal to the City Council.

Section 9.24.040 then boxes in how a permitted loudspeaker can actually run: only between 8:00 a.m. and 9:00 p.m.; a vehicle-mounted unit can't broadcast unless the vehicle is moving at least 10 miles per hour, except when stopped by traffic, and then for no more than one minute per stop; no sound may be emitted within 100 yards of a hospital, school, church or courthouse; no obscene, lewd, indecent or slanderous speech is allowed; sound from equipment next to residential property can't be heard past the parcel line except as allowed under §17.84.040; volume is capped at 75 decibels as measured under §17.84.040; and the same vehicle can't pass the same street point more than twice per hour. Loudspeaker noise must also independently comply with the general nuisance-noise standard in §9.24.010, which weighs volume, duration, timing and the noise's residential or commercial origin.
