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

Lodi Municipal Code Chapter 9.24 regulates noise citywide, and Section 9.24.030(B) specifically targets amplified sound equipment used in public places. The rule reaches any drum, radio, phonograph, loudspeaker, sound amplifier, stereo, television or similar sound system, and it does not matter whether the equipment is mounted in a vehicle or set up at a fixed location: if it is clearly audible fifty feet away on a public street, public right-of-way or in a city park, the person operating it is in violation. The city council's stated rationale, written into the ordinance, is that sound carrying that far interferes with drivers' and pedestrians' ability to hear approaching traffic and warning signals, a public-safety concern rather than a purely aesthetic one.

The ordinance singles out nighttime use for extra weight: playing the same equipment on streets and rights-of-way adjacent to public parks between 10:00 p.m. and 7:00 a.m., audible at fifty feet or more, is declared prima facie evidence of a violation, meaning the city does not have to separately prove the equipment was disruptive once the distance and time are established. Section 9.24.050(C) exempts sound equipment operating under a city license or permit, and equipment used for a First Amendment-protected activity, and Section 9.24.030(B) itself exempts radio systems licensed by the Federal Communications Commission operating in the regular course of business. Enforcement runs through the police department or the director of community development under Section 9.24.070, and Section 9.24.060 sets the penalty at an infraction capped at $250. This subsection is separate from the nighttime ambient-decibel standard in Section 9.24.030(C), which measures sound level at a property line rather than audibility distance on public property.
