Quiet hours in Montebello, CA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Montebello has no single citywide quiet-hours curfew. Chapter 9.08 of the Municipal Code bans any 'loud and raucous noise' at all times, and sets prima facie nighttime windows for amplified sound, yelling, loading and construction noise.
Montebello regulates noise through Chapter 9.08 (Offenses Against Public Peace), not a fixed dBA curfew. Section 9.08.020 makes it unlawful to make or allow any loud or raucous noise, defined in Section 9.08.030 as sound disturbing a reasonable person of ordinary sensitiveness; two or more complaints are prima facie evidence. Instead of one curfew, Section 9.08.050 sets nighttime windows treated as presumptive violations: amplified radios and stereos audible next door and yelling between 8 p.m. and 7 a.m.; loading and box-opening 10 p.m. to 7 a.m.; sound trucks 9 p.m. to 10 a.m. Any loud or raucous noise is a public nuisance. LA County Code Chapter 12.08 governs only unincorporated areas, not incorporated Montebello.
Under Section 9.08.060, any noise violation is a misdemeanor or infraction, each a separate offense. Repeated disturbance calls to one location within 24 hours trigger a service-fee charge; chronic violations may be abated as a public nuisance.
