South Gate has explicit, numeric limits on amplified music. Under SGMC §7.44.020.02(b), any radio, television, record player, tape or video recorder, or other electronic entertainment device that can be heard more than 225 feet from the source is an 'offensive portable noise emission' and a misdemeanor. The same section sets a decibel scale: 70 dB at 10 feet, 68 dB at 15 ft, 65 dB at 20 ft, 62 dB at 25 ft, 60 dB at 30 ft, 58 dB at 35 ft.

Santa Monica FAQ
Can I play loud music at home in Santa Monica?
Music must not exceed noise zone limits (50 dBA at night, 55 dBA daytime in residential zones). Enforcement uses a reasonable person standard.
What happens if my neighbor plays loud music after 10 PM?
Contact Code Enforcement or SMPD. The 50 dBA nighttime residential limit applies, and the catch-all provision of §4.12.025 covers unreasonable noise.
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.
