Do I need a permit for shed or accessory structure in Isle of Palms?
It depends. Whether shed or accessory structure needs a permit in Isle of Palms comes down to the details of your project.
Accessory structures are called out as permitted work by the Isle of Palms Building and Planning Department, so confirm your shed size and use at 843-886-9912 before assuming a small shed is exempt, since a false no-permit assumption is the risky direction. City zoning places accessory structures in the rear yard behind the plane of the main structure with minimum distances to the property line, and running power or water to a shed adds a separate electrical or plumbing permit. On a barrier island, a shed must meet the coastal high-wind anchoring provisions, and a structure in the Special Flood Hazard Area faces the city's flood construction and freeboard requirements, including the design flood elevation of one foot above base flood elevation. A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured. South Carolina has a statewide answer and the figure is 200 square feet. Section R105.2 of the 2021 South Carolina Residential Code exempts, other than storm shelters, one-story detached accessory structures where the floor area does not exceed 200 square feet. The South Carolina Building Codes Council adopted the 2021 codes effective 1 January 2023 and they are mandatory statewide. The exemption is from the permit, not from the rules. R105.2 states that exemption "shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction", so zoning setbacks, HOA limits and flood requirements still apply. Counties and municipalities both run building offices in South Carolina, so confirm which one covers your address before you apply. Running electrical power or plumbing to a shed requires its own permit even when the structure itself is exempt.
