Huntington Park, CA Noise Ordinances: Quiet Hours (2026)

Huntington Park builds its quiet hours out of several time-specific rules in Article 5, Noise Standards, of the Zoning Code (Ordinance 666-NS, effective September 15, 2001). The general prohibition is § 9-3.504: it is unlawful to willfully make or continue any loud, unnecessary or unusual noise that disturbs the peace or quiet of any neighborhood or constitutes a public nuisance. Section 9-3.505 lists what counts in deciding a violation, including the loudness, the proximity of the noise to residential sleeping facilities, the time of day or night, the duration and whether the noise is recurrent, intermittent or continuous, and whether the source is residential or nonresidential.

Section 9-3.507 then fixes the night window at 8:00 p.m. to 7:00 a.m. for specific activities. Item 3 bars repairing, rebuilding, modifying or testing any motor vehicle, motorcycle or motorboat in a manner that causes a noise disturbance within or adjacent to any residential area. Item 4 says parking and landscape area activities such as mechanical sweeping, mechanical grass cutting and mechanical blowing shall not impact residential uses, and that no parking area or landscape maintenance shall occur in that window if it would cause a noise disturbance to a residential area. Item 2 adds the same window for loading and unloading, and item 1 sets a 65 dBA property line limit from 10:00 p.m. to 8:00 a.m. for sound devices.

The window shifts for exempt work. Under § 9-3.506, construction noise is exempt only outside 7:00 p.m. to 7:00 a.m. on weekdays including Saturdays and never on Sundays or Federal holidays, and real property maintenance is exempt unless it falls between 8:00 p.m. and 7:00 a.m. or earlier than 9:00 a.m. on Sundays and Federal holidays. Section 5-14.06 treats sound plainly audible at fifty feet between 10:00 p.m. and 7:00 a.m. as prima facie evidence of a violation.
