How do you check a contractor license in South Carolina?

South Carolina's Residential Builders Commission licenses or registers residential builders, residential specialty contractors and home inspectors, and its home page links to a Licensee Lookup. Larger commercial work sits with the Contractor's Licensing Board instead. A lookup is an optional public-record step.

A yearly roster also goes to each county's clerk of court. Section 40-59-50 of the South Carolina Code, on the state legislature's site, reads: "A roster including the names and places of business of the residential builders and residential specialty contractors licensed or registered by the commission during the preceding year must be prepared annually by the commission and forwarded to and filed with the clerk of court for each county."

When does a South Carolina home job need a residential builder?

The size of the job matters. The Commission's residential builder page puts it this way: "A Residential Builder is one who constructs, superintends, or offers to construct or superintend the construction, repair, improvement, or reimprovement of a residential building or structure which is not over three floors in height and which does not have more than sixteen units in any single apartment building, when the cost of the undertaking exceeds five thousand dollars."

Local permit offices are part of the picture too. Section 40-59-280 of the code reads: "The building official, or other authority charged with the duty of issuing building or similar permits, of any incorporated municipality or subdivision of the municipality or county shall refuse to issue a permit for an undertaking which requires licensure or registration under this chapter unless the applicant has furnished evidence that he is either licensed or registered in accordance with this chapter or exempt from the requirements of this chapter."

What do South Carolina specialty contractors register or license for?

Roofers, painters, masons and other single-trade workers come under the Commission as residential specialty contractors. Its specialty page gives the definition: "Residential Specialty Contractor means an independent contractor who contracts with a licensed residential builder, general contractor, or individual property owner to do construction work, repairs, improvement, or reimprovement which requires special skills and involves the use of specialized construction trades or craft, when the undertakings exceed five hundred dollars ($500) and are not regulated by the provisions of Chapter 11, Title 40."

The page sets a limit on trades: "A Residential Specialty Contractor Registration is limited to three trade classifications."

On exams, the same page says: "An examination is not required to become a registered specialty contractor."

Three trades are different. Section 40-59-20 of the code reads: "Plumbers, electricians, and heating and air conditioning installers and repairers must be issued specialty contractor licenses after passing the required examination, if the other requirements of this article are met."

On bonds for bigger specialty jobs, section 40-59-240 reads: "When the total cost of materials and labor for an undertaking performed by a residential specialty contractor for an individual property owner exceeds five thousand dollars, the residential specialty contractor shall obtain an executed bond with a surety in an amount approved by the commission and shall furnish a signed original to the commission."

What can a South Carolina homeowner do before signing a contract?
