Full Breakdown
Lansing Codified Ordinances Section 654.07(k) sets the City's clearest numeric noise ceiling: air conditioning, air handling devices, refrigeration equipment, and other compressors may not produce a continuous sound level above 55 dBA measured at any property line in a residential area. The limit doesn't apply if the unit's noise raises the pre-existing ambient sound level by less than 3 dBA, a narrow exception for equipment that isn't meaningfully louder than the surrounding neighborhood. The standard sits within the general noise chapter, which applies citywide to nonindustrial sound sources in Lansing, Ingham County.
Violations & Fines
Exceeding the 55 dBA limit is a misdemeanor under the Code's general penalty section, punishable by up to a $500 fine plus costs, up to 90 days in jail, or both; each day of violation counts separately.
