Summary
Kansas City treats air conditioners, heat pumps and other HVAC equipment as a regulated 'source of sound,' capping property-line noise at 60 dBA by day and 55 dBA at night on residential property under the citywide noise code's Table I.
No person shall make, cause, suffer, continue, allow or permit the operation of any source of sound on any receiving property in such a manner as to create a sound level that equals or exceeds the sound level limits set forth in table I, when measured at the real property boundary or within the real property lines of any of the receiving properties listed in table I.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 139 | Zoning and Development Code: Supplement 38).
Full Breakdown
Kansas City's noise code doesn't single out HVAC, but Section 46-4(a) bars operating any 'source of sound', which covers AC condensers, heat pumps and rooftop mechanical units, above the limits in Table I when measured at the real property boundary. Residential property is capped at 60 dBA outdoors from 7:00 a.m. to 10:00 p.m. and 55 dBA overnight, dropping to 45/40 dBA indoors; commercial property gets 80 dBA outdoors around the clock. A reading only counts as a violation if it exceeds ambient noise by more than 5 dB, and Health Department noise control officers can measure at the boundary or at the complainant's property if that's more practical.
Violations & Fines
First violation draws a $100 administrative citation from the Health Department, rising to $300, $500 and up to $1,000 for repeat violations within 12 months. Each day of continued violation is a separate offense, and the director of health can also issue an abatement order.
