Full Breakdown
Rather than one citywide decibel cap, South Gate's noise control program (Chapter 11.34) sets a table of maximum sound levels by noise zone: Noise Zone I (noise-sensitive areas such as schools and hospitals) caps at 45 dBA at any time; Zone II (residential properties in any zone) caps at 50 dBA from 7 a.m. to 10 p.m. and drops to 40 dBA overnight. The standards apply to all noise sources, ambient noise, equipment, animals, tools, vehicles, or gatherings, and are measured at the property line under the noise control officer's oversight. A separate table permits short, limited decibel spikes above these ceilings depending on how long the noise lasts.
Violations & Fines
Exceeding the zone's decibel ceiling is a misdemeanor under Chapter 11.34, with each day of continuing violation a separate offense.
