Do I need a permit for shed or accessory structure in Summerville?
It depends. Whether shed or accessory structure needs a permit in Summerville comes down to the details of your project.
The Town of Summerville reviews detached accessory structures such as sheds, garages, and carports on the plot plan, so whether a small shed needs a building permit depends on size and construction, and the Building Department at 843-851-4203 is the office that decides for addresses inside the town limits. The town notes that detached residential structures of 800 square feet or less, one story, with a roof pitch of 7 in 12 or less and not habitable may not need a design professional seal, but that guidance is about drawings, not a permit exemption, so confirm the permit requirement rather than assuming a shed is exempt. Zoning setbacks still apply to shed placement, running power, water, or gas to a shed adds a separate trade permit, and a shed on a home in the Downtown Historic District can require Board of Architectural Review approval. 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.
