Construction hours in Durham, NC — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Durham regulates construction noise under Ch. 26, Sec. 26-4. Loud construction, drilling, and demolition is prohibited 11 PM to 8 AM. After-hours permits are available when work is necessary.
Under Sec. 26-4, construction and demolition activities that produce unreasonably loud and disturbing noise are specifically listed as prohibited acts. The general sound level limits of 60 dBA daytime (8 AM to 11 PM) and 50 dBA nighttime (11 PM to 8 AM) apply to construction sites. Durham allows the city to issue permits for construction work during otherwise restricted hours when the work is deemed necessary for public safety or infrastructure needs. North Carolina state law under N.C.G.S. 160A-184 grants municipalities the authority to regulate noise including construction activities. Contractors working on public projects or emergencies may receive exemptions. Residential complaints about construction noise can be filed through Durham One Call at (919) 560-1200.
Construction noise violations are enforced under the general noise ordinance provisions. Violations are misdemeanors with no warnings issued for first offenses. Contractors may face stop-work orders in addition to citations. Fines of up to $500 per violation may apply, and repeated violations can result in permit revocation.
