Johnson County has not adopted a numeric noise ordinance with set quiet hours for unincorporated territory. Enforcement defers to Kansas's disorderly conduct statute, K.S.A. 21-6203, which makes it an offense to engage in noisy conduct that tends reasonably to arouse alarm, anger, or resentment in others. The Johnson County Sheriff's Office (913-782-0720) is the responding agency for unincorporated noise complaints. Inside the cities — Overland Park, Olathe, Lenexa, Shawnee, Mission, Leawood, Prairie Village, and others — each maintains its own numeric noise ordinance with set quiet-hour windows.
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.
Disorderly conduct under K.S.A. 21-6203 is a class C misdemeanor on first conviction, punishable by up to one month in jail and a fine up to $500. Repeated calls to the same address may also support nuisance claims. Inside Johnson County cities, municipal noise violations are prosecuted in each city's municipal court — typical fines run $100 to $500 per offense, with each day or each unique disturbance treated as a separate violation. Persistent unaddressed noise can support civil nuisance suits in Johnson County District Court.
