S.C. Code Ann. § 40-59-130
Any residential builder or residential specialty contractor who undertakes or attempts to undertake the business of residential building or residential specialty contracting without first having procured a valid license or registered with the commission as required in Section 40-59-50 which has neither expired nor been revoked, or who knowingly presents to, or files with, the commission false information for the purpose of obtaining a license or becoming registered is guilty of a misdemeanor and, upon conviction, must be fined not less than one hundred dollars or imprisoned for not less than thirty days.
A residential builder who does not have a license or residential specialty contractor who is not registered as required may not bring any action either at law or in equity to enforce the provisions of any contract for residential building or residential specialty contracting which he entered into in violation of this chapter.
Whenever it appears to the commission that any residential builder or residential specialty contractor has violated, or is about to violate, the provisions of this chapter, the commission may in its own name petition an administrative law judge as provided under Article 5 of Chapter 23 of Title 1 to issue a temporary restraining order enjoining the violation of this chapter, pending a full hearing to determine whether or not the injunction must be made permanent.
