Shawnee, KS Noise Ordinances: Quiet Hours (2026)

Authority: K.S.A. Chapter 19 (county government) and K.S.A. 21-6203 (disorderly conduct). Kansas counties draw their land-use and police-power authority from K.S.A. 19-101 et seq.; counties may adopt noise codes by separate resolution but Johnson County has not done so for unincorporated territory. The operative state rule is K.S.A. 21-6203, which prohibits using fighting words or engaging in noisy conduct that tends reasonably to arouse alarm, anger, or resentment in others — a class C misdemeanor punishable by up to one month in jail and a fine. The Johnson County Sheriff's Office responds to unincorporated calls and follows a complaint-based model: residents are encouraged to talk to the neighbor first, then call the Sheriff's non-emergency dispatch at 913-782-0720 (911 if there is an active threat). Inside Johnson County's incorporated cities, separate municipal noise codes apply: Overland Park (Code Chapter 7.08) sets numeric decibel limits and quiet-hour rules; Olathe Municipal Code Chapter 6.16 prohibits unreasonable noise with quiet-hour overlays; Lenexa, Shawnee, Mission, Leawood, Prairie Village, De Soto, Edgerton, Gardner, Spring Hill, and others each maintain their own ordinances. Always confirm whether your address is inside city limits before assuming county-level rules apply.
