Carson FAQ
Can I have a DJ at my backyard party?
Yes, during permissible hours (before 10 p.m.), provided the amplified sound is not plainly audible at 50 feet from your property line. After 10 p.m. it must be brought inside or shut down.
Do I need a permit for amplified sound at a public event?
Yes. LA County Code §12.08.490 requires a sound-amplifying device permit for public-place amplification. Apply through Carson City Hall / LA County Sheriff.
What about concerts at Dignity Health Sports Park?
Stadium events operate under separate noise-mitigation conditions tied to the CSU Dominguez Hills CUP and CEQA findings - not the general residential noise ordinance.
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.
