Sutter FAQ
Is loud car audio illegal in unincorporated Sutter County?
Yes. Both county Zoning Code Sec. 1500-21.5-060(B) and California Vehicle Code Sec. 27007 prohibit vehicle sound systems audible more than 50 feet from the vehicle in public streets and places.
Are loud exhausts covered by county noise rules?
Vehicle exhaust on public roads is regulated by state law: Vehicle Code Sec. 27150 requires an adequate muffler and Sec. 27151 prohibits modified exhaust exceeding 95 dBA. Off-road vehicle use on private property is treated as private recreation, exempt only 7 a.m. to sunset and under 65 dBA Leq at the property line (Zoning Code Sec. 1500-21.5-070(G)).
Yuba City FAQ
Can Yuba City write its own loud-exhaust ordinance?
Generally no — Vehicle Code §21 preempts local regulation of on-road vehicle equipment, so loud-exhaust enforcement happens under state §§27150–27151.
What's the dBA limit for a motorcycle in Yuba City?
California Vehicle Code §27202 sets 80–82 dBA depending on model year, measured under SAE J331 procedures. This applies statewide, including Yuba City.
What about a loud truck idling on my street at 3 a.m.?
On-road noise is Vehicle Code territory (call Yuba City PD); if the truck is parked on private property, Chapter 17's reasonable-person standard applies and you can call Code Enforcement at (530) 822-4703.
