Do I need a permit for interior remodeling in Sumter County (Unincorporated)?
Most likely yes. Interior remodeling usually requires a permit in South Carolina. Confirm the specifics with Sumter County (Unincorporated).
Purely cosmetic work such as paint, flooring and cabinet swaps usually does not need a permit, but moving a wall or changing electrical, plumbing or mechanical does. When in doubt, ask the building department before you start. In a home built before 1978, disturbing painted surfaces can involve lead-safe work practices. Factor this into an older-home remodel. A remodel that moves walls or includes electrical, plumbing, or mechanical work falls outside cosmetic exemptions, which cover finishes such as paint, flooring, trim, and cabinets. Each trade normally needs its own permit and inspection on top of the building permit, and removing or altering a load bearing wall usually requires a beam detail or engineering before the work is approved. Opening walls in an older home can trigger separate lead paint, asbestos, and smoke alarm requirements, so raise those with your department at application time.
