Do I need a permit for basement finishing in Aiken County (Unincorporated)?

Permit required

Yes. In South Carolina, basement finishing generally requires a permit, and Aiken County (Unincorporated) is no exception.

S.C. Code Section 6-10-50 says construction, which Section 6-10-20 defines to include alteration of a building, must not begin until a building permit is issued. South Carolina's amendment to NEC 210.8(A) requires GFCI protection for 125-volt basement receptacles, with an exception for receptacles in walk-out basements. The 2009 International Energy Conservation Code is the statewide energy standard (S.C. Code Section 6-10-30), so new conditioned space needs insulation that meets it.
