Residential Noise Limits
In South Dakota, the typical residential noise limit is 65 dB during the day and 55 dB at night.

Quiet hours — the period when stricter nighttime limits apply — run from 10:00 PM to 7:00 AM in most South Dakota jurisdictions. During these hours, activities that generate noise above the nighttime limit may result in a citation. Exemptions typically apply to emergency services, emergency repairs, and certain agricultural operations.

Some cities allow Saturday construction with shorter hours (often 8:00 AM to 5:00 PM), while Sunday and holiday construction is typically prohibited in residential areas. Emergency construction and utility repairs are usually exempt from time restrictions.
Fines and Penalties
Noise ordinance violations in South Dakota typically carry fines ranging from $50-$200. First-time offenders usually receive a warning or the minimum fine. Repeat offenders face escalating penalties.
