Summary
Lansing, Michigan caps the steady noise from air conditioners, heat pumps, refrigeration units and other compressors at 55 dBA measured at a residential property line. Lansing Codified Ordinances Section 654.07(k) forgives the rule only if the equipment adds less than a 3 dBA increase over the neighborhood's existing background sound.
No person shall make, or continue, cause or permit to be made, verbally or mechanically, any unnecessary noise disturbance. The following acts, and the causing thereof, are hereby declared to be violations of this section: ...(k)Air Conditioning and Air Handling Devices. The operation of air conditioning, air handling devices, refrigeration devices or other compressors causing a continuous sound level in excess of fifty-five dBA measured at any property line in residential areas. This subsection shall not apply if the sound from the air conditioner or air handling device produces less than a three dBA increase in the sound level that exists in the absence of such sound.

Full Breakdown
' It bars operating air conditioning, air handling devices, refrigeration devices or other compressors that cause a continuous sound level above 55 dBA, measured at any property line in a residential area. The section builds in a practical carve-out: the limit doesn't apply if the equipment's sound produces less than a 3 dBA increase over the ambient sound level that already exists without it, recognizing that a unit barely audible above street noise or other background sound isn't the target of the rule. 03, as land zoned A, A-1, B, C, DM-1, DM-2, DM-3 or DM-4 under the Zoning Code or an adopted zoning map, so the 55 dBA ceiling is tied to the zoning district at the property line, not to whether the specific parcel happens to be a house.
The rule sweeps in central air conditioners, window units, heat pumps, walk-in refrigeration compressors behind restaurants, and similar mechanical equipment wherever its continuous hum crosses into one of those residential zoning districts. 07.
Violations & Fines
Section 654.07 doesn't carry its own fine schedule, so an HVAC noise violation is punished under the Code's general penalty, Section 202.99: a misdemeanor with a fine up to $500 plus prosecution costs, up to 90 days in jail, or both. Because the rule is measured against a continuous sound level rather than a single incident, a persistent violation, such as an undersized or poorly mounted compressor that runs above 55 dBA for weeks, can also be charged as a separate offense for each day it continues under Section 202.99(e).
