Carson Municipal Code Art. 4 Ch. 5 adopts LA County Code Title 12 Ch. 12.08 by reference. Section 12.08.390 sets exterior decibel standards by Noise Zone (defined in §12.08.380).

Carson FAQ
What is Carson's nighttime residential noise limit?
45 dBA between 10 p.m. and 7 a.m., measured at your property line — per LA County Code §12.08.390 (Noise Zone I), adopted by Carson Municipal Code Art. 4 Ch. 5.
Do I need a sound level meter to file a noise complaint?
No. While the formal standard is a measured dBA reading, Carson Code Enforcement and the LA County Sheriff's Carson Station respond to plainly-audible-from-50-feet violations and may issue citations based on officer observation under LA County Code §12.08.560 (amplified sound) and §12.08.570 (animal noise).
What if my neighbor's stereo is loud but only for 5 minutes at a time?
Short-duration loud noise is still regulated by a graduated table — +15 dBA above the standard is allowed for 1–5 minutes per hour, but not more. Sustained amplified sound audible at 50 ft in a residential zone is a per se violation regardless of duration.
Are emergency generators and HVAC equipment regulated?
Yes — stationary mechanical equipment must comply with the property-line dBA limits. Carson's Building Code (CMC Art. 4) and CALGreen Title 24 Part 11 §5.507 also require noise attenuation for new commercial HVAC located near residential.
