S.C. Code Regs. § § 61-93.600.608
In instances when there have been no Patients in a Facility for any reason for a period of ninety (90) days or more, the Facility shall notify the Department in writing that there have been no admissions, no later than the one hundredth (100th) calendar day following the date of departure of the last active Patient. At the time of that notification, the Department shall consider, upon appropriate review of the situation, the necessity of inspecting the Facility prior to any new and/or readmissions to the Facility. In the event the Facility is at zero census or temporarily closed, the Licensee is still required to apply and pay the licensing fee to keep the License active. If the Facility has no Patients for a period longer than one (1) year and there is a desire to admit a Patient, the Facility shall re-apply to the Department for licensure and shall be subject to all licensing requirements at the time of that application, including construction-related requirements for a new Facility.
