Full Breakdown

Section 31-75 of Flint's Noise Control Ordinance bars operating any source of continuous noise, sound that varies less than 5 dB(A) over at least five minutes, the profile typical of machinery, HVAC equipment, and other steady industrial operations, that exceeds the maximum permissible sound levels, measured at the real property line of the receiving land use. For an industrial area, defined at § 31-71 as land zoned E, F, or G or devoted to a principal industrial use, the cap is 70 dB(A) daytime and 65 dB(A) nighttime, higher than the 60/50 dB(A) residential limit and 65/60 dB(A) commercial limit, but still enforceable at the boundary line.

Violations & Fines

Exceeding the cap is a misdemeanor under § 31-78: a fine up to $1,500, up to 90 days in jail, or both.
