Construction hours in Charleston County, SC — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Charleston County's Livability chapter sets no dedicated construction-hours window. Jobsite noise is governed by the general excessive-noise rule (Section 3-43): sound plainly audible within 500 feet of a residential property line or above 70 dBA can be cited, so early-morning or overnight work is where complaints land.
Unlike many city codes, the unincorporated Charleston County code (Chapter 3, Livability) does not list specific permitted construction hours. Contractors are instead held to the same excessive, unnecessary or unreasonable sound standard as everyone else under Section 3-43 (500-foot plainly-audible test or 70 dBA). Individual municipalities in the county — Charleston, North Charleston, Mount Pleasant, Folly Beach — do impose their own construction-hour limits, so verify the governing jurisdiction before scheduling work.
Construction noise that violates Section 3-43 is a misdemeanor subject to a fine of up to $500.00.
