Full Breakdown
05 lists the noises exempt from Chatham County's general noise ordinance, and construction is the first exception in division (A). on Sundays, for work under an issued building permit or work that does not require one, but only if all equipment runs according to the manufacturer's specifications and with the manufacturer's mufflers and noise-reducing equipment in use and in proper operating condition. 04 separately caps sound at 60 decibels at the receiving property without a noise permit, or 80 decibels with one under a defined schedule.
04(C) even if the same activity would have been exempt during permitted hours. 01, handles enforcement of both the general prohibition and the hours-based construction exemption: a sound meter is not required to prove a violation of the general unreasonably-loud standard, so a deputy can cite based on the officer's own assessment of the noise and the time of day.
Violations & Fines
Running construction equipment outside the 7 a.m.-9 p.m. weekday or 8 a.m.-7 p.m. Sunday window forfeits the § 92.05(A) exemption and exposes the contractor or property owner to a misdemeanor citation under § 92.02, or under § 92.04(C) if the sound also exceeds 60 decibels at the receiving property without a permit.
