S.C. Code § 27-47-520
Upon termination of a tenancy, monies held by the owner as a security deposit or prepaid rent must be returned less amounts withheld by the owner for accrued rent or damages the owner has suffered by reason of the resident's noncompliance with Section 27-47-510. Deductions must be itemized in a written notice to the resident within thirty days after termination of the tenancy. The resident shall provide the owner a forwarding address. The owner is not liable for damages if the resident does not provide a forwarding address and the owner has no notice of the resident's address and mails the notice to the resident's last known address. If the owner does not return monies due the resident, he may recover an amount equal to three times the amount wrongfully withheld and reasonable attorney's fees.
