Los Angeles County
South San Gabriel is an unincorporated community in Los Angeles County, so amplified music is governed by County Code Title 12, Chapter 12.08 (Noise Control), not a city ordinance. Residential limits are 50 dBA daytime (7 a.m.-10 p.m.) and 45 dBA nighttime (10 p.m.-7 a.m.) at the property line under Sec. 12.08.390.

South Gate FAQ
Can South Gate police shut down my backyard party?
Yes. Under §7.44.020.02(c), if two or more people's noise can be heard 30 feet beyond your property line, the gathering is an offensive portable noise emission and police can order it shut down. Continued operation can be charged as a misdemeanor with each hour a separate count under §7.44.050(a).
What is the actual decibel limit for outdoor music in South Gate?
§7.44.020.02(b) sets a sliding scale: 70 dB measured at 10 feet from the source, 65 dB at 20 ft, 62 dB at 25 ft, 60 dB at 30 ft, and 58 dB at 35 ft, on a slow-response meter. Independently, if the sound is plainly audible more than 225 feet from the source, that alone is a violation.
Do these rules apply during the day too?
Yes. Chapter 7.44 does not specify quiet-hours windows — the audibility, decibel, and 30-foot party limits apply 24 hours a day. Time of day can affect the reasonable-person analysis under §7.44.020.02(a) for borderline cases, but the bright-line distance and decibel limits in (b) and (c) are time-independent.
South San Gabriel FAQ
Can I have amplified music in my South San Gabriel backyard?
Yes, but the sound at your property line cannot exceed 50 dBA between 7 a.m. and 10 p.m. or 45 dBA between 10 p.m. and 7 a.m. under LA County Code Sec. 12.08.390. Amplified DJs and live bands routinely exceed those limits and require a Public Health permit.
Who do I call about a loud party in South San Gabriel?
Call the LA County Sheriff's Temple Station at 626-285-7171 for an active disturbance. South San Gabriel is unincorporated, so the Sheriff (not a city police department) is the responding agency under Chapter 12.08.
