S.C. Code § 58-11-870
Pursuant to the provisions of this article and applicable federal law, an authority may continue to exercise zoning, land use, planning and permitting authority within its territorial boundaries with respect to small wireless facilities, poles, and support structures outside of the ROW, including the enforcement of applicable codes. An authority does not have and may not exercise any jurisdiction or authority over the design, engineering, construction, installation, or operation of a small wireless facility located in an interior structure or upon the site of a campus, stadium, or athletic facility not owned or controlled by the authority, other than to require compliance with applicable codes. Nothing in this article authorizes the State or any agency, department, or instrumentality thereof, including an authority, to require any wireless facility deployment or to regulate wireless services.
