Full Breakdown
City Code § 36-8 makes it unlawful to operate mechanical and fire equipment, air conditioning compressors, pumps, blowers, exhaust fans, filters and similar noise-producing equipment, on residential, institutional, commercial or industrial property when it exceeds set decibel limits measured at the nearest receiving property line with an ANSI-standard sound level meter. For single-family property the cap is 5 dBA above ambient or 55 dBA, whichever is greater, between 10:00 p.m. and 7:00 a.m., rising to 5 dBA above ambient or 60 dBA between 7:00 a.m. and 10:00 p.m. Multifamily, institutional and park zones get 60/65 dBA; retail commercial gets 65 dBA around the clock; wholesale commercial and industrial gets 70/75 dBA. This sits inside Chapter 36 (Noise), alongside separate sections on construction equipment (§ 36-6) and steam/gas emissions (§ 36-7).
Violations & Fines
Running an AC compressor, condenser, exhaust fan or similar unit above the listed dBA ceiling for its zone and time period violates § 36-8; enforcement runs through the city's general noise and code compliance process rather than a fixed statutory fine printed in this section.
