Do I need a permit for shed or accessory structure in Horry County (Unincorporated)?
It depends. Whether shed or accessory structure needs a permit in Horry County (Unincorporated) comes down to the details of your project.
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. In Horry County, permits outside the cities are handled by the Horry County Code Enforcement office, reachable on 843-915-5090 at https://www.horrycountysc.gov/departments/code-enforcement/. Its online permit portal is https://egweb.horrycounty.org/EnerGov_prod/selfservice#/home. Horry County accepts residential building permit applications directly. Several municipalities in the county also run their own building offices, so confirm which one covers your address. Ask specifically about the size that triggers a permit and about setbacks, since those are set locally and are the two things people most often get wrong on a shed.
