Torrance Quiet Hours Rules (2026): What You Need to Know

Torrance's noise ordinance under TMC Division 4, Chapter 6 declares it the policy of the city to prohibit unnecessary, excessive, and annoying noises. The ordinance covers all sources subject to the city's police power and establishes noise level standards based on geographic regions within the city. Region 1, which surrounds the oil refineries in the industrial area, permits higher levels (70 dBA day, 65 dBA night), while standard residential areas have lower thresholds.

A key provision is the 5-decibel rule: any noise exceeding the ambient noise level at the property line of residential land by more than 5 decibels is deemed prima facie evidence of a violation. This applies to machinery, equipment, pumps, fans, air conditioning units, and similar mechanical devices. The ordinance also specifically addresses radios, musical instruments, televisions, and other sound-reproducing devices, prohibiting their use in a manner that disturbs the peace and comfort of neighboring residents.

Amplified sound equipment in public places requires a permit and is restricted to 9:00 AM to 9:00 PM (except on Sundays and legal holidays). Exceptions for events outside these hours require City Council approval on a case-by-case basis. Train horns are prohibited between 10 PM and 7 AM if they create noise exceeding 96 dB at 300 feet.
