Summary
In the Town of Chapel Hill, Town Code § 11-40(b) exempts permitted construction operations from the noise article only between 7:00 a.m. and 9:00 p.m. on weekdays and 8:00 a.m. and 9:00 p.m. on weekends, provided equipment runs with proper mufflers and noise-reducing equipment.
The following are exempt from the provisions of this article: ... (b)Construction operations from 7:00 a.m. to 9:00 p.m. on weekdays and 8:00 a.m. to 9:00 p.m. on weekends for which building permits have been issued, or construction operations not requiring permits due to ownership of the project by an agency of government; providing all equipment is operated in accord with the manufacturer's specifications, and with all standard equipment, and with manufacturer's mufflers and noise-reducing equipment in use, and in proper operating condition.
Full Breakdown
Section 11-40 lists the activities exempt from the Noise Control Code's general property-boundary decibel limits, and subsection (b) exempts 'construction operations from 7:00 a.m. to 9:00 p.m. on weekdays and 8:00 a.m. to 9:00 p.m. on weekends for which building permits have been issued, or construction operations not requiring permits due to ownership of the project by an agency of government,' but only if all equipment is operated according to the manufacturer's specifications and with the manufacturer's mufflers and noise-reducing equipment in use and in proper operating condition.
Construction noise that runs outside that daily window, before 7:00 a.m. or after 9:00 p.m. on a weekday, or before 8:00 a.m. or after 9:00 p.m. on a Saturday or Sunday, loses the § 11-40(b) exemption and falls back under the general nuisance rule in § 11-39.1(a), which bars unreasonably loud noise, particularly at night, and the property-boundary decibel tables in § 11-39, 50 dBA daytime and 45 dBA nighttime at a residential line. Section 11-40(n) separately exempts non-government infrastructure work performed under a town-issued permit, which can cover certain utility-related construction noise outside a builder's own permit.
Enforcement of construction noise outside permitted hours still runs through § 11-42, where the town gives an oral order to cease or abate before or alongside a citation.
Violations & Fines
Construction noise that falls outside the § 11-40(b) exemption is enforced as a general noise nuisance: a first violation within twelve months draws a written warning and/or a $25 civil citation under § 11-43(a), rising to $75, $150, and up to $500 for repeat violations, with each continuing day a separate offense. The town may instead prosecute the violation as a misdemeanor punishable by up to $250 and ten days in jail, and a contractor cited may appeal to the town manager within fifteen days.
