Summary
Columbus classifies air-conditioning and refrigeration equipment as a "stationary sound source" under its noise code, capping how far the sound can carry past your property line before it's a violation.
"Stationary sound source" means a machine or device capable of creating a noise level at the property upon which it is regularly located, including...air-conditioning apparatus or refrigeration machines...No person shall operate or permit the operation of any sound amplification system, auditory device, or stationary sound source from a residential unit in a manner as to be audible at a distance of fifty (50) feet beyond the property line of the property from which the sound emanates.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 85 | Form Based Code: ?).
Full Breakdown
Columbus City Code § 2329.11 defines a "stationary sound source" to include air-conditioning apparatus and refrigeration machines. Running one from a residential unit so it's audible 50 feet past your property line is a strict-liability violation; the distance shrinks to 25 feet where units sit within 50 feet of each other, as in duplexes or close-set houses. A commercial AC or condenser running overnight (10 p.m.-7 a.m.) that's audible at a residential property line 100+ feet away also violates the code. Residential receiving land uses also cap the hourly average sound level at 60 dBA at night and 65 dBA by day.
Violations & Fines
Minor misdemeanor on the first offense; a repeat violation after a warning within 12 hours becomes a fourth-degree misdemeanor. Non-residential property owners face civil fines up to $5,000 for repeat violations.
