Lynwood, CA Noise Ordinances: Quiet Hours (2026)

Lynwood Municipal Code § 3-12.7 imposes a nighttime quiet-hours rule on residential-zone sound devices: radios, musical instruments, phonographs, televisions or any other machine that produces or reproduces sound may not be operated between 10:00 p.m. and 7:00 a.m. in a manner that disturbs the peace, quiet and comfort of neighboring residents or a reasonable person of normal sensitiveness in the area. Subsection b builds in an objective backstop to that subjective standard: if the device pushes the noise level at the complaining property's line, or inside an adjoining unit in a condominium or apartment building, more than five decibels above the ambient base level set for the zone under § 3-12.5, that reading is prima facie evidence of a violation, meaning the complaint does not rest on a neighbor's opinion alone.

The rule sits inside the broader Chapter 3 noise article: § 3-12.6 separately bans wilfully making a loud, unnecessary or unusual noise that disturbs the peace at any hour, while § 3-12.13 imposes the same 10:00 p.m. to 7:00 a.m. window on outdoor construction equipment and § 3-12.14a applies it to vehicle repair work in residential areas. The Los Angeles County Sheriff's Department, contracted to Lynwood through the Century Station, and the city's code enforcement officers respond to and cite quiet-hours complaints, applying the ambient base noise readings taken under the § 3-12.4 measurement procedure.
