Minnehaha County, SD Noise Ordinances: Quiet Hours (2026)

Minnehaha County's Public Nuisance Ordinance MC33-04 (adopted 11/23/2004, amended 8/18/2007) enumerates 14 categories of nuisance in Section 2 — abandoned property, breeding places for pests, careless burning, dead animals, garbage, manure handling, litter, water pollution, private landfills, rubbish, and noxious weeds — but does NOT include noise, music, machinery sound, or quiet-hour provisions. The Planning Director enforces only the enumerated nuisances. For unincorporated-area noise complaints, the Minnehaha County Sheriff's Office relies on SDCL 22-18-35 (disorderly conduct — 'making unreasonable noise' that causes serious public inconvenience, annoyance, or alarm, Class 2 misdemeanor) and on civil nuisance actions under SDCL 21-10-1 (unlawful act or omission that 'annoys, injures, or endangers the comfort, repose, health, or safety of others'). The state disorderly-conduct standard is subjective ('unreasonable') rather than decibel-based, so enforcement depends on officer judgment and complainant testimony. Residents inside incorporated cities (Sioux Falls, Brandon, Hartford, Dell Rapids, Crooks, Garretson, Humboldt, Valley Springs) are governed by that city's municipal noise ordinance, not by county rules.
