Summary
In the City of Lenexa, Kansas, construction, excavation, demolition and repair sound that is plainly audible across a residential property line between 7:00 p.m. and 7:00 a.m. is a prima facie violation. Between 7:00 a.m. and 7:00 p.m., that sound is not subject to the code's dB(A) limits.
3. Prima Facie Violations. It shall be unlawful to conduct or allow to be conducted any of the following noise-producing activities so as to cause a sound plainly audible across any property boundary line in a residential area during specified times. The fact that the noise is plainly audible across a property boundary line constitutes prima facie evidence of a violation of this Section. ... a. A sound resulting from the erecting, constructing, excavating, demolishing, altering, or repairing of any structure, or operating, or permitting the operation of any tools or equipment used in construction, drilling, or demolition work in such a manner as to cause a sound plainly audible across any property boundary line between the hours of 7:00 p.m. and 7:00 a.m. Between the hours of 7:00 a.m. and 7:00 p.m., sounds resulting from these activities shall not be subject to the time, area, and dB(A) limits set forth in Section 4-1-C-4-E-2.
Full Breakdown
Section 4-1-C-4-E-3-a of the Lenexa City Code covers a wide list of work: erecting, constructing, excavating, demolishing, altering or repairing any structure, and operating any tools or equipment used in construction, drilling or demolition. The night rule is a plainly audible test, not a meter test. If the sound is plainly audible across any property boundary line between 7:00 p.m. and 7:00 a.m., the fact that it is audible is prima facie evidence of a violation.
The lead-in to Section 4-1-C-4-E-3 limits the rule to a residential area, meaning property zoned RE, RP-E, R-1, RP-1 through RP-5, AG, or a PUD with residential uses (Section 4-1-C-4-E-1-i). The daytime window is protected in the text itself: from 7:00 a.m. to 7:00 p.m., sounds from these activities are not subject to the time, area and dB(A) limits in Section 4-1-C-4-E-2. A contractor working a weekday morning at 7:15 a.m. is therefore outside the 70 dB(A) residential day cap that applies to other sources.
Vibration has its own daytime carve-out. Section 4-1-C-4-F-1 exempts vehicular traffic and nonblasting vibration from temporary construction activity that occurs between 7:00 A.M. and 7:00 P.M. Blasting is separate: Section 4-1-C-4-F-2 sets peak particle velocity limits and lets the Fire Chief modify them for specific purposes.
A person cannot avoid the rule by pointing at a hired crew. Section 4-1-C-4-E-6 makes it unlawful for a property owner, tenant or other person in control of residential property to allow a noise disturbance, and makes that person responsible for abating it. Section 4-1-C-4-E-7-c exempts sound made under a valid license or permit from a City department, board or commission that specifically allows the sound.
Violations & Fines
The Community Standards Officer enforces through Article 3-5-H. A Notice of Violation states that each alleged violation is punishable by a fine of not more than $2,500, imprisonment for not more than one year, or both (Section 3-5-H-7-B-3-e). The recipient has 10 days to ask in writing for a hearing. Each day of violation is a separate offense under Section 1-1-C-3.
