Sioux Falls, SD
Noise Code

Operating equipment for construction, repair, alteration, or demolition work must not cause a sound pressure level exceeding 75 dBA measured at a distance of 50 feet. No specific quiet hours are explicitly stated for construction, but general noise prohibitions would apply.

Operating any amplified sound device is unlawful between 10:30 PM and 6:00 AM if it is plainly audible at the property boundary of the source, 50 feet from a parked vehicle, or 100 feet from a moving vehicle. Permits are required for certain loud noises after 10:30 PM, such as concerts or racing events. Public loudspeakers for commercial advertising or music transmission are prohibited if they cause a noise disturbance or violate specific decibel limits.

Barking dogs that create a nuisance should first be addressed with the owner. If the problem persists, Animal Control (605-367-7000) should be contacted when the dog is barking. An officer will respond and may issue citations if the barking continues.

Unnecessary engine noise, tire squeal, and exhibition driving are prohibited. Motor vehicles must be equipped with an exhaust system and muffler in good working condition, free from defects affecting sound reduction, and without cutouts or bypass devices. Noise limits are 90-94 dBA for vehicles 10,000 lbs or more GVWR/GCWR, and 80-84 dBA for other motor vehicles, measured at 25 feet. Horns and signaling devices are to be used only as danger warnings, not for unnecessary or unreasonable periods. Recreational vehicles and snowmobiles operating in a manner that causes a noise disturbance are also prohibited.
