Do I need a permit for pavers, driveway, or hardscape in Mount Pleasant?
It depends. Whether pavers, driveway, or hardscape needs a permit in Mount Pleasant comes down to the details of your project.
A simple at-grade paver patio or walkway may not need a building permit, but drainage, impervious coverage limits, and zoning setbacks can still apply, so confirm with the Building Inspections Division at 843-884-5184 before starting. Work that touches a driveway apron or the public right of way, or a retaining wall over the code height threshold, can require a permit and engineered design, and homes in the Special Flood Hazard Area face added fill and grading rules since the town permits all floodplain development including clearing, fill, and regrading. In the Old Village Historic District, changes to walls, driveways, and hardscape visible from the street can require a Certificate of Appropriateness from the Historic District Preservation Commission. South Carolina has a statewide answer here. Section R105.2 of the 2021 South Carolina Residential Code, mandatory statewide since 1 January 2023, exempts sidewalks and driveways from a building permit, along with painting, papering, tiling, carpeting, cabinets, countertops and similar finish work. A patio is not named in that list, so confirm a paver patio with your local department rather than assuming it is exempt. The retaining wall line is precise: exempt only where the wall is not over 4 feet in height measured from the bottom of the footing to the top of the wall, and does not support a surcharge. A wall carrying a surcharge needs a permit at any height. Large impervious areas can trigger stormwater or drainage review, and you should always locate underground utilities before excavating.
