Do I need a permit for pergola or trellis in Sumter?
It depends. Whether pergola or trellis needs a permit in Sumter comes down to the details of your project.
South Carolina's statewide code adoption does not include the codes' administrative chapters (S.C. Code Section 6-9-50 and the Building Codes Council's adoption notice). The list of work exempt from a permit is set by each city or county ordinance, so ask your local building office before assuming an exemption applies. An open-roof pergola is the version most often exempted locally. Adding a solid or louvered roof, attaching it to the house, or running power to lights or fans makes a permit much more likely. South Carolina adopted IRC Appendix AH (Patio Covers) statewide, so a pergola with a solid roof may be reviewed as a patio cover. A solid, waterproof or louvered roof turns an open pergola into a roofed structure, which departments generally review like a patio cover, with attention to roof framing and wind loads. An open lattice or rafter pergola is the version most often treated as minor, so if you are comparing designs, ask your department how it treats each one before you buy a kit.
