Tradesmen in the electrical, plumbing, gas and mechanical fields are required to provide proof of proper licensing. South Carolina Master Certificates will be accepted as will City of Dillon Master Cards. Other state licenses may also be accepted. After each individual card or state license is reviewed and verified by the Code Enforcement Office and the Board of Governors, a decision will be made on its validity. A twenty-four (24) hour wait may be necessary so that we may better research the credentials of a master tradesman.
