Quiet hours in Lodi, CA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Lodi Municipal Code Chapter 9.24 (Noise Regulation) prohibits excessive, offensive, or disturbing noise citywide, with elevated enforcement against loud noise between 10:00 p.m. and 7:00 a.m. The ordinance is built around a 'plainly audible' standard rather than fixed decibel caps.
Chapter 9.24 of the Lodi Municipal Code (Title 9, Public Peace, Morals, and Welfare) governs general noise in the city. The most-cited provision, Lodi Municipal Code §9.24.030, makes it unlawful to operate any radio, television, drum, phonograph, loudspeaker, sound amplifier, stereo, or similar sound-producing device 'in such a fashion that it is clearly audible at a distance of 50 feet' on public streets, sidewalks, rights-of-way, or in public parks. Lodi Police Department has confirmed via the Lodi News-Sentinel 'Ask Jennifer' civic column that officers routinely enforce the chapter, and that conduct creating high levels of noise between 10:00 p.m. and 7:00 a.m. is treated as a violation of the city code. Lodi did not adopt fixed dBA/dBC caps the way many larger California cities have; instead enforcement turns on the 'plainly audible at 50 feet' test plus a general nuisance standard. Code Enforcement (Community Development, 209-333-6700) follows a progressive process - courtesy notice, notice of violation with 15 days to cure, then administrative citation - before fines are issued.
A violation of Chapter 9.24 is enforced through Lodi's progressive code-enforcement process: a courtesy notice (15 days to cure, no fine), then a Notice of Violation (15 days, no fine), then an Administrative Citation carrying monetary penalties. Persistent violators can face inspection warrants, liens, orders to abate, and injunctions. Lodi PD can also cite under §9.24.030 as a misdemeanor in serious cases.
