Full Breakdown
Midwest City Code § 26-6(a) bans operating any 'stationary source of sound', which covers air conditioning condensers, heat pumps and rooftop mechanical units, above the percentile sound levels set in Table I of § 26-12. In residential districts the cap is 55 dBA from 7 a.m. to 10 p.m. and 50 dBA from 10 p.m. to 7 a.m.; commercial/office limits run 60/55 dBA and industrial/agricultural 70 dBA around the clock. Where a unit sits near a property line shared with a different owner, the level is measured at that line, not at the equipment itself, and impulsive sound limits drop by 5 dBA.
Violations & Fines
Enforcement officers can issue a 24-hour abatement order before filing in municipal court under § 26-9; continuing violations count as a separate offense each day, per § 26-10.
