Contractor licensing

South Carolina contractor license requirements

South Carolina licenses general and mechanical contractors for commercial work over $10,000 through the Contractor's Licensing Board, and residential builders for jobs over $5,000 through the Residential Builders Commission. Your license group caps the size of job you can take.

Yes, South Carolina has a statewide contractor license, and it actually has two systems. Commercial general and mechanical contracting over $10,000 needs a license from the South Carolina Contractor's Licensing Board under Title 40, Chapter 11 of the Code. Residential building over $5,000 on structures of three floors or fewer falls under the Residential Builders Commission and Chapter 59. Both boards sit inside the Department of Labor, Licensing and Regulation (LLR). What makes South Carolina different from most states is the group system: your financial strength sets a hard cap on the size of each job you can contract.

Who needs a South Carolina contractor license

Under S.C. Code Section 40-11-30, anyone doing general or mechanical contracting where the total cost of construction is greater than $10,000 must hold a license. That threshold used to be $5,000. 2023 Act No. 69 raised it to $10,000, effective May 19, 2023, so older guides and old bid documents may still show the lower number.

Licensing also controls bidding, not just the work. Section 40-11-200(B) makes it a violation for an owner, awarding authority, or contractor to consider a bid, sign a contract, or let a contractor start work before the required license is in place. A bid submitted while unlicensed cannot be resubmitted later. If you are an estimator with three bids due Friday on a $250,000 job, check the license group before the numbers go out, not after award.

License groups and the net worth you need

Section 40-11-260 sorts every commercial license into Groups 1 through 5. The group sets the most you can contract on a single job, and each group requires a minimum net worth (or a lower working capital figure). Larger groups also require a stronger financial statement: owner-prepared for Groups 1 and 2, CPA-compiled under GAAP for Groups 3 and 4, and an audited balance sheet for Group 5.

General contractor groups, S.C. Code Section 40-11-260
GroupMax per jobNet worth or working capitalInitial statement
1$100,000$20,000 or $10,000Owner-prepared
2$400,000$60,000 or $40,000Owner-prepared

4$3,000,000$250,000 or $175,000CPA-compiled
5Unlimited$350,000 or $250,000Audited
Mechanical contractor groups, S.C. Code Section 40-11-260
GroupMax per jobNet worth or working capitalInitial statement
1$35,000$7,000 or $3,500Owner-prepared
2$100,000$15,000 or $10,000Owner-prepared
3$200,000$30,000 or $20,000CPA-compiled
4$400,000$60,000 or $40,000CPA-compiled
5Unlimited$300,000 or $200,000Audited

Under Section 40-11-262, a surety bond in the same amount as the required net worth can stand in for the financial statement. Say a Group 2 general contractor is offered a $480,000 tenant improvement. The license tops out at $400,000 per job, so the company either moves up to Group 3 (with a CPA-compiled statement and $150,000 net worth) or passes. That is why the financial statements bonding companies want matter here even for licensing, not only for bond capacity.

Classifications

Each license also carries one or more classifications from Section 40-11-410. General contractor classifications are Building, Highway (bridges, concrete paving, asphalt paving, grading, highway incidental), Public Utility (pipe lines, water and sewer plants and lines), and Specialty. Specialty covers trades such as concrete, masonry, roofing, structural framing, nonstructural renovation, marine, swimming pools, glass and glazing, and wood frame structures. Mechanical classifications are Air Conditioning, Heating, Packaged Equipment, Electrical, Lightning Protection Systems, Plumbing, Pressure and Process Piping, and Refrigeration. You may use unlicensed subcontractors under Section 40-11-270(E) only if you provide supervision.

How to get a South Carolina commercial license

  1. Pick the classification and group that matches the work and job sizes you plan to bid.
  2. Name a qualifying party. Section 40-11-240 requires a certified qualifying party in a responsible management position. A primary qualifying party generally needs two years of full-time experience in the classification within the last five years, and one person can qualify only one licensee (with a limited exception).
  3. Pass the exams. The qualifying party must score 70 percent or better on the technical exam where required and on the South Carolina law exam. For General Building, Groups 1 to 3 may use the limited building exam (structures up to three stories); Groups 4 and 5 need the unlimited general exam. Retakes are limited to two attempts in twelve months, then one every six months.
  4. Prove financial strength with the right statement for your group, or a surety bond.
  5. Apply to the Contractor's Licensing Board and pay the fees LLR lists on its application.
  6. Renew every two years. A lapsed license can be renewed within ninety days with late fees; after that you reapply as a new licensee.

If the qualifying party leaves, notify LLR within 15 days and name a replacement within 90 days. Contractors licensed in another state can sometimes skip the technical exam under Section 40-11-290 if South Carolina has a waiver agreement with that state, though the business, law, and project management exam may still be required.

Residential builders and specialty contractors

Chapter 59 defines a residential builder as anyone who builds, superintends, repairs, or improves a residential structure of no more than three floors and sixteen units when the cost exceeds $5,000. A residential specialty contractor does trade work over $500 for a builder, general contractor, or owner. Plumbers, electricians, and HVAC installers must pass an exam; other specialty trades register without one. Builders need at least one year of supervised experience (or approved equivalent) before the exam, plus a bond of at least $15,000 or proof of financial responsibility. A licensed Chapter 11 general or mechanical contractor is generally exempt from Chapter 59.

The stakes are real: an unlicensed residential contractor who needed a license cannot file a mechanics lien or sue to enforce the contract, and building officials must refuse permits without proof of a license or exemption.

Exemptions and penalties

  • Owners building for themselves: both chapters let an owner improve their own residence for personal or family occupancy. A sale or rental within two years of completion is treated as evidence the work was not exempt.
  • Minor residential work: Section 40-59-265 lets an owner of residential property make certain small improvements, such as fences under seven feet, small decks, and finish work, without a permit or a residential license.
  • Commercial penalties: administrative fines up to $500 for a first violation and $1,000 for a second within five years, civil penalties up to $5,000 per violation, and a misdemeanor carrying up to one year or a $5,000 fine. An unlicensed entity cannot sue to enforce its contract (Section 40-11-370).
  • Residential penalties: unlicensed work is a misdemeanor with a fine of $500 to $10,000.

South Carolina contractor license lookup

Use the Licensee Lookup link on the LLR website to check a contractor's status, classification, and group before you sign a subcontract. Check the group as well as the status: a sub with a Group 1 mechanical license cannot legally take a $60,000 plumbing package. Keep the result with the certificate of insurance in your sub file. Smart Business Automator tracks license numbers, insurance certificates, and expiration dates for every sub so nothing lapses mid-job. See subcontractor compliance automation.

Frequently asked questions

What is the dollar limit for working without a license in South Carolina?

For commercial general or mechanical contracting, a license is required when the total cost of construction is greater than $10,000 (raised from $5,000 in 2023). Residential builder work needs a license over $5,000, and residential specialty work over $500 needs a license or registration.

Does South Carolina require a separate license for residential work?

Yes. Residential builders and residential specialty contractors are licensed by the Residential Builders Commission under Chapter 59. A licensed Chapter 11 general or mechanical contractor is generally exempt from Chapter 59.

How much net worth do I need for a South Carolina general contractor license?

It depends on the group. Group 1 (jobs up to $100,000) needs $20,000 net worth or $10,000 working capital, while Group 5 (unlimited) needs $350,000 net worth or $250,000 working capital. A surety bond in the same amount can replace the financial statement.

Can I bid a South Carolina job before my license is issued?

No. Section 40-11-200 bars owners and contractors from considering a bid or signing a contract before the required license is obtained, and a bid submitted while unlicensed cannot be resubmitted.

How often do South Carolina contractor licenses renew?

Commercial licenses under Chapter 11 renew every two years, with a ninety day late renewal window. Residential licenses carry an annual fee on a renewal period set by commission regulation.
