Noise Ordinances in Charleston, SC

If you live in Charleston or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Charleston has 5 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Amplified Music & Outdoor Sound

Charleston bans amplified music in privately owned courtyards and outdoor areas after 11 p.m. and before 7 a.m. if it can be heard from a public street. Unamplified instruments in the same spaces face a later midnight-to-7-a.m. cutoff, and brass or drum instruments are singled out for the tighter 11 p.m. limit either way.

Key details: Amplified sound curfew: 11:00 p.m. to 7:00 a.m.. Unamplified instrument curfew: Midnight to 7:00 a.m.. Brass/drum instruments: Barred outdoors after 11 p.m. always. Applies to: Any person, entity, or establishment. Exemption: Registered sound trucks under §21-26.

Charleston Police Department officers cite violations under the general municipal penalty in Section 1-16 because Section 21-16 sets no separate fine: up to a $500 fine or 30 days in jail, with continuing nightly violations chargeable as separate offenses. Officers can issue a Uniform Ordinance Summons on the spot under Section 1-20 without a custodial arrest.

Vehicle Noise

City Code § 21-16(c) makes it unlawful to operate a motorized vehicle, including cars, trucks, motorcycles, and mopeds, in a manner that emits loud, unnecessary, or long-continued noise disturbing the peace and quiet of the city, whether on a public street or private property. The prohibition specifically names rapid throttle advancing, or revving, of an internal combustion engine as a covered violation.

Key details: Governing section: City Code § 21-16(c). Covered vehicles: Cars, trucks, motorcycles, mopeds, scooters. Specifically named act: Rapid throttle advancing (revving). Applies: On public streets and private property. Horn exception: Safety and passenger-notification use allowed.

A person, entity, or establishment that violates § 21-16, including by revving an engine loudly enough to disturb the peace, is subject to Charleston's general penalty provision under § 1-16 of the Code, since Article II does not set its own separate fine schedule. Police officers may cite drivers directly for the noise violation, and the same section governs excessive courtyard music, amplified sound, and loud gatherings.

Decibel Limits

Charleston's zoning code sets a hard numeric noise ceiling only for certain LI and Upper Peninsula district manufacturing conditional uses: no more than 67 decibels (dBA) at lot lines touching residential zones, or 72 dBA at lot lines touching non-residential zones, measured at least 1,000 feet from roads and rail lines under Section 54-207(i)(3)(a).

Key details: Residential-adjacent limit: 67 dBA at lot line. Non-residential-adjacent limit: 72 dBA at lot line. Applies in districts: Light Industrial and Upper Peninsula only. Covered use categories: 26, 30-39, 7692 (manufacturing). Vibration cap: 65 velocity decibels at lot line.

Failing the 67/72 dBA standard blocks conditional-use approval outright, since the Zoning Administration must make the compliance finding before permitting the use. Once approved, exceeding the standard is a Section 54-950 zoning misdemeanor punishable by a fine and/or incarceration, with each day of continued violation a separate offense, and the zoning administrator can withhold permits or issue a stop order against the operation.

Construction Hours

Charleston limits loud construction equipment to 7 a.m. to 7 p.m. on weekdays and 9 a.m. to 7 p.m. on Saturdays. Section 21-17 bars pile drivers, excavators, backhoes, pneumatic hammers, and similar power equipment outside those hours, and forbids all loud construction work on Sundays and six named city holidays.

Key details: Weekday hours: 7:00 a.m. to 7:00 p.m.. Saturday hours: 9:00 a.m. to 7:00 p.m.. Sundays/holidays: No loud construction work allowed. Concrete pours: Require 48 hours' resident notice. After-hours permit: 7-day permit, renewable on reapplication.

Section 21-17 imposes no standalone fine, so contractors who run loud equipment outside the permitted hours face the Code's general penalty under Section 1-16: up to a $500 fine or 30 days in jail, with each day of continued after-hours work a separate offense. Section 21-17(d) makes clear that compliance with the construction-hours limit does not excuse a contractor from also complying with the general noise restrictions in Section 21-16.

Barking Dogs

Charleston prohibits owning or keeping a dog that barks or howls so much it disturbs the neighborhood's peace, under City Code § 5-18. The code defines "excessive noise" for animals as sound that occurs consistently and exceeds 20 minutes.

Key details: Governing section: City Code § 5-18. Excessive noise definition: Consistent, exceeds 20 minutes. Enforcing agency: Animal control division. Citation authority: § 5-25, probable cause. Penalty: Up to $500 fine or 30 days jail.

An animal control officer or law enforcement officer with probable cause may issue a citation under § 5-25 directing the owner to appear in municipal court, delivered in person or by certified mail if the owner can't be located; the violation is subject to the chapter's general penalty under § 1-16, up to a $500 fine and/or 30 days in jail, with each day the barking nuisance continues counted as a separate offense.

The Bottom Line

Charleston's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Charleston is broadly strict or permissive.
