South Gate Municipal Code Chapter 11.34 (Noise Control Program) sets dBA Leq limits at the receiving-property line, measured against the actual ambient noise level. Noise standards are land-use-based and inclusive of ambient noise per Table 11.34-1. South Gate's manufacturing legacy (former GM Assembly site, active heavy-industrial corridors along Atlantic Ave, Tweedy Blvd, and the Alameda Corridor rail line) means industrial-to-residential conflicts are common. Industrial uses must meet the noise standard of the receiving zone, not the source zone — so a factory abutting a residential parcel must comply with residential limits at that shared property line. South Coast AQMD also separately regulates equipment-source emissions.

South Gate FAQ
A factory next to my house runs all night — what limit applies?
The receiving-property's land use determines the limit. If your home is in a residential zone, the factory must keep noise at your shared property line at or below the residential nighttime standard (~40 dBA Leq) inclusive of ambient, per Chapter 11.34.
Can South Gate shut down a noisy industrial use?
Persistent violations can trigger administrative citations, conditional-use-permit review, or nuisance abatement. South Coast AQMD Rule 402 and Cal. H&S Code §41700 provide additional shutdown leverage for genuine public nuisances.
What about loading docks and truck idling?
Idling diesel trucks over 5 minutes are prohibited statewide under 13 CCR §2485 (CARB Anti-Idling Rule). Loading-dock noise must comply with Chapter 11.34 standards at the receiving property line.
