Summary
In the City of Lenexa, Kansas, Section 3-9-E-3 makes it unlawful to take part in or be present at a party whose sound disturbs a reasonable neighbor in a residential area. Police can order everyone out of the dwelling instead of writing charges, and sound plainly audible across a property line between 7:00 P.M. and 7:00 A.M. is prima facie evidence of a violation.
Elements of Disturbing the Peace: It shall be unlawful for any person to: ... Congregate because of, participate in or be in any party or gathering of people from which sound emanates of a sufficient volume so as to disturb the peace, quiet or repose of any reasonable person of normal auditory sensitivity residing in any residential area. No person shall visit or remain within any residential dwelling unit wherein such party or gathering is taking place except persons who have gone there for the sole purpose of abating said disturbance. A police officer may order all persons present in any group or gathering from the dwelling unit to immediately disperse in lieu of being charged under this Section. Prima Facie Violation: The operation of any tool, ... or other noise- or sound-producing device at any time in such a manner as to be plainly audible across a property boundary line in a residential area, or for fifty feet (50') or more in the case of a multiple-family dwelling, between the hours of seven o'clock (7:00) P.M. and seven o'clock (7:00) A.M. shall be prima facie evidence of a violation of this Section.
Full Breakdown
Section 3-9-E-3 is the disturbing the peace ordinance in the Lenexa City Code, and its third clause is the one aimed at parties. It makes it unlawful to congregate because of, participate in or be in any party or gathering of people from which sound emanates of a sufficient volume to disturb the peace, quiet or repose of any reasonable person of normal auditory sensitivity residing in any residential area. The standard is a reasonable neighbor, not a decibel reading.
The clause reaches guests as well as hosts. No person can visit or remain within a residential dwelling unit where such a party or gathering is taking place, with one carve-out: people who have gone there for the sole purpose of abating the disturbance. That gives the Lenexa Police Department a choice at the door. An officer can order all persons present in the group or gathering to disperse from the dwelling immediately, in lieu of charging anyone under the section.
The code also adds a presumption. Operating a tool, equipment, vehicle, electronic device or other sound-producing device so that it is plainly audible across a property boundary line in a residential area, or for fifty feet or more in the case of a multiple-family dwelling, between 7:00 P.M. and 7:00 A.M. is prima facie evidence of a violation. The exceptions are narrow: sound from police and other emergency vehicles, sound from government or utility vehicles and equipment working a potentially hazardous situation, sound made under a City license or permit that specifically allows it, and emergency generators running when grid electricity is unavailable.
Parties with underage drinkers face a second rule. Section 3-9-G-4 makes it unlawful to intentionally or recklessly permit your residence, or any land, building, structure or room you own, occupy or procure, to be used by your invitee, or an invitee of your child or ward, in a manner that results in people under 21 possessing or consuming alcoholic liquor or cereal malt beverage there. That offense carries a minimum fine of $1000.00.
Violations & Fines
Section 3-9-J-1 treats an offense under Chapter 3-9 as a public offense punished under Section 1-1-C-3 unless another penalty is stated: a fine of up to $2,500, imprisonment for up to one year, or both. Each day a violation continues is a separate offense, and the code lets a court revoke City licenses and permits the offender holds. Hosting underage drinking under Section 3-9-G-4 carries a minimum fine of $1000.00.
