Summary
Guilford County's general noise ordinance treats government street construction as exempt from its 'unreasonably loud' standard only when equipment meets manufacturer noise specifications, and it caps blasting and pile driving on those street projects to 7:00 a.m. to 10:00 p.m., Monday through Saturday. Outside that window, or on Sundays, blasting and pile driving on a county or state road project lose the Sec. 11-8(d)(2) exemption and become an enforceable noise violation.
Any street construction activity performed by, or on behalf of, a government agency on streets designated on the then current thoroughfare plan as adopted county or state; provided that all equipment is operated in accordance with the manufacturer's specifications and is equipped with all legally required noise-reducing devices in proper operating condition. Blasting and pile driving on street projects are covered under this exemption only to the extent that they are carried on between the hours of 7:00 a.m. and 10:00 p.m., Monday through Saturday.
Full Breakdown
Sec. 11-8(a) bars any noise that is unreasonably loud, disturbing or unnecessary, judged by time of day, proximity to homes, whether it is constant or recurring, its volume, and whether it could be controlled without unreasonable cost. m. Subsection (d) then carves out exceptions 'in the interest of public safety and convenience': emergency repair work, utility restoration work, and street construction performed by or for a government agency on a road in the current thoroughfare plan, so long as the equipment runs to the manufacturer's specifications and carries required noise-reducing devices.
Sec. , Monday through Saturday. S. 153A-340(b)(2) and aircraft or Piedmont Triad Airport Authority activity are exempted separately under (d)(3) and (d)(4). A property owner who is not the current occupant can still be held civilly liable for a tenant's or guest's violation, but only after being notified by personal service or certified mail of an earlier violation within the prior 12 months.
Violations & Fines
The Sheriff's Office or a person the county manager designates in writing can issue a written warning or a civil citation: $200 for a first offense, $400 for a second within a year, and $500 for each one after that, plus a $50 late fee if unpaid within ten days. Each day a violation continues is a separate offense, and the county may also prosecute under G.S. 14-4 as a Class 3 misdemeanor punishable by up to a $500 fine, seek an injunction or abatement order, or use any remedy under G.S. 153A-123.
