South Gate FAQ
Can I have a backyard DJ for a quinceañera until midnight?
Generally no after 10 p.m. — Chapter 11.34 nighttime limits (~40 dBA at the neighbor's property line) effectively prohibit amplified music audible across the property line. South Gate residents commonly receive Sheriff visits after 10 p.m. for sustained amplified events. Plan to wrap amplified music by 10 p.m. and shift to acoustic/recorded background sound.
Are restaurant patios allowed to play music outdoors?
Yes, provided sound at the nearest residential property line stays within Chapter 11.34 daytime (~50 dBA) or nighttime (~40 dBA) limits. Many commercial permits include conditions requiring amplified sound to face away from residential neighbors.
Are churches really exempt at any volume?
The religious-services exemption in Chapter 11.34 applies to bona fide worship services. Sustained outdoor amplified events unrelated to worship are not exempt. State law (Cal. H&S Code §41700) still provides a public-nuisance backstop.

Large outdoor events with amplified sound in unincorporated LA County may require a temporary use permit from the Department of Regional Planning, especially if attendance exceeds normal gathering sizes.
