How to Start a General Contractor Business in South Carolina: CLB License, Groups and Bonds

If you want to run a general contractor business in South Carolina, the core requirement is the Contractors' Licensing Board (CLB) license. Most people searching for a south carolina general contractor license want the same three answers: when a license is required, what it takes to qualify, and how the Group and bond system works. This guide walks through each step in the order you will actually complete them.

This article is informational content, not legal or tax advice. Licensing rules, fees and forms can change, so confirm current requirements with the agencies named below and consult a qualified attorney or CPA for decisions about your specific situation.

Do You Need a South Carolina General Contractor License?

You need a CLB license when the total cost of construction on a project is over $10,000. The Legislature raised that threshold from $5,000 in 2023 through Act 69, so many older guides list the wrong number. Keep that in mind when you read older articles or forum posts.

The threshold matters for more than your own paperwork. South Carolina law makes it grounds for the CLB to refuse a license to a contractor who bids on work while unlicensed (S.C. Code Section 40-11-130). It also bars owners from considering bids from unlicensed contractors (Section 40-11-200). In practice, that means a homeowner or commercial client who hires you without a license can run into problems, and that usually shows up as lost bids for you.

Residential specialty work follows a separate rule. Residential specialty registration applies to jobs above $500, which is a different track from the general contractor license. If your business will mix general contracting with specialty trades, confirm which credential each job type needs before you bid.

Materials and Documents You Will Need

Gather these before you start the application. Missing one item usually means a delayed file, not a rejected one, but it still costs you time.

• Your Primary Qualifying Party (PQP) information. The PQP is the individual whose experience and exam results support the license. You need a clear record of their work history.
• Proof of two years of experience within the last five years. Gather pay stubs, signed project records, prior license certificates or employer letters that show the work was in the classification you are applying for.
• Proof of financial capacity for your target Group. This can be working capital, net worth documentation, or a surety bond. Step 3 explains the options.
• A surety bond, if you choose that route. A bond amount equal to the net worth figure for your Group is one way to meet the financial requirement.
• Your business entity documents. If you form an LLC or corporation, you need the filed Articles of Organization or Articles of Incorporation.
• Exam registration with PSI. PSI administers the business and law exam and the technical exams.
• A local business license from each city or county where you operate. South Carolina has no general statewide business license, so this step is separate.
• Payment for the $350 initial license fee, plus any application or exam fees the CLB or PSI charges. Confirm those extra fees directly with the agencies before you budget.

Step 1: Choose Your Classification and Group

South Carolina has 20 general contractor classifications that require a PSI technical exam, plus five classifications that require only the business and law exam. One classification to know about is Nonstructural Renovation, which replaced the older Interior Renovation name. If your work is mostly finishing, remodeling or interior projects that do not touch structural elements, this classification may fit your business better than a broader one.

Your classification and your Group work together. The Group controls how large a job you can bid, and the limit goes up at each level:

Group	Maximum job size	Financial proof options
Group 1	$100,000	Working capital, net worth, or a surety bond at the Group 1 net worth figure
Group 2	$400,000	Working capital, net worth, or a surety bond at the Group 2 net worth figure
Group 3	$1,000,000	Working capital, net worth, or a surety bond at the Group 3 net worth figure
Group 4	$3,000,000	Working capital, net worth, or a surety bond at the Group 4 net worth figure
Group 5	Unlimited	Working capital, net worth, or a surety bond at the Group 5 net worth figure

The surety bond amounts in these Groups range from $20,000 to $350,000, depending on the net worth figure the Group requires. Confirm the exact figure for the Group you pick with the CLB before you buy a bond, because you will be locked into that bond amount for the application.

Tip: Pick the Group you can support today, not the one you hope to reach. A higher Group requires more financial proof, and you can usually move up later once your records show it.

Step 2: Name Your Primary Qualifying Party

Every licensed general contractor business needs a Primary Qualifying Party. The PQP must have at least two years of experience within the last five years in the construction field covered by the license. The PQP is the person whose qualifications stand behind the license, so the choice has real consequences.

If you are the owner and you have that experience, you can usually serve as the PQP. If you plan to hire a supervisor or partner to meet the experience requirement, make sure that person is willing to take on the role and that the paperwork is airtight. A PQP who leaves the company can create a compliance problem, so plan for who will fill the role if your original PQP moves on.

Step 3: Prove Your Financial Capacity

Each Group requires you to prove financial capacity. You have three ways to do it:

1. Working capital. Show that the business has the cash or liquid resources the Group requires. Your accountant can prepare a statement that meets the CLB format.
2. Net worth. Show that the business or owner holds net worth equal to the figure for your Group. Keep your balance sheets current and signed.
3. Surety bond. Buy a bond in the amount equal to the net worth figure for your Group. Bond amounts range from $20,000 to $350,000 across the Groups. A surety company will look at your credit and financial history before issuing the bond, so start that conversation early.

Many new contractors choose the bond because it is the fastest way to show capacity without a large cash balance. The tradeoff is cost. You pay a premium to the surety, and you may have to pay that premium again at renewal. Compare quotes from more than one surety, and ask your CPA how the premium fits into your first-year budget.

Step 4: Pass the Exams

Your exam path depends on your classification:

• Classifications with a technical exam require the PSI business and law exam and the PSI technical exam for that classification. All 20 technical-exam classifications fall here, including Nonstructural Renovation.
• The five classifications without a technical exam require only the business and law exam.

The CLB accepts NASCLA exams as well. If you already hold NASCLA scores, check with the CLB whether those scores match your classification before you register for PSI, so you do not pay for a test you do not need.

Study for the business and law exam even if you have years of field experience. It covers contract terms, lien rules, licensing obligations and the legal framework for running a contracting business, which is where many first-time applicants lose points. Confirm exam fees and scheduling directly with PSI, since this guide does not list them as settled figures.

Step 5: Submit the Application and Pay the License Fee

Once your PQP, Group, financial proof and exams are in order, submit the application to the CLB. The initial license fee is $350. The license is renewed every two years at $135, and general contractor licenses expire October 31 of even-numbered years.

Timing note: If you are reading this in October 2026, the next expiration date for general contractor licenses is October 31, 2026. If you already hold a license, put that date on your calendar now, and confirm your renewal status with the CLB before it passes.

Keep copies of everything you submit, including payment receipts and exam score reports. If the CLB asks for a document you already sent, you can answer quickly, and that speeds up the whole process.

Step 6: Set Up Your Business Entity

South Carolina does not require a general contractor to form a company, but most contractors do so for liability and tax reasons. Sole proprietors and general partnerships do not file organizing documents with the Secretary of State. An LLC or corporation does. This is a decision to make with your attorney and CPA, because the choice affects liability, taxes and how you sign contracts.

• LLC. The filing fee for Articles of Organization is $110. The name must include Limited Liability Company, Limited Company, LLC, L.L.C., LC or L.C., and it must be distinguishable from other registered names. An LLC does not file an annual report in South Carolina.
• Corporation. The filing fee for Articles of Incorporation is $110. You must also file Form CL-1 with a one time $25 initial License Fee within 60 days of doing business or using capital in South Carolina. The recurring annual report is filed with your corporate income tax return.
• Registered agent. An LLC must designate and continuously maintain an agent with a South Carolina street address. The agent must be a South Carolina resident, a domestic corporation or an authorized entity, and the agent's name and address must appear on your formation document.

File online through Business Entities Online at businessfilings.sc.gov. Documents filed online are returned within 24 to 48 business hours. Mailed and in person filings take longer, and the Secretary of State does not publish a mail turnaround window. Search for your name first at the business entity search so you do not file a name that will be rejected.

If you plan to use a name other than your legal name in marketing, such as a trade name, South Carolina has no state level DBA filing. You record the DBA with the county or municipality, typically on the local business license, and list it as a trade name on your IRS EIN application and your SCDOR Business Tax Application.

Step 7: Get Your Local Business License

South Carolina has no general statewide business license. Registering with the Secretary of State does not count as a business license. Instead, you must hold a local business license tax registration in every city or county where your business operates.

Most cities levy a business license tax, and nine counties do as well: Beaufort, Charleston, Dorchester, Horry, Jasper, Marion, Orangeburg, Richland and Sumter. Those jurisdictions use a standardized class schedule. The license year runs May 1 to April 30, and the license is due April 30. Renewals are processed at localblrenewal.com.

If you work across several jurisdictions, you may owe a license in each one where you perform work. Ask the city or county clerk how the standardized class schedule applies to general contracting, because the classification you use can change the amount.

Common Mistakes to Avoid

• Using the old $5,000 threshold. The CLB license requirement starts above $10,000 in total construction cost. Quoting jobs as though the threshold were still $5,000 can put you on the wrong side of the law.
• Bidding before you are licensed. A bid submitted without a license can be grounds for refusal of your application, and owners cannot consider unlicensed bids. Wait for your license before you quote any job above the threshold.
• Choosing a Group too high for your finances. A bigger Group means bigger jobs, but it also means a bigger financial requirement and a bigger bond premium.
• Relying on an old experience record. The two years of experience must fall within the last five years. Work from a decade ago does not count toward the current window.
• Assuming the state license covers your city. The CLB license does not replace the local business license. Missing the local license is one of the most common gaps for new contractors.
• Missing the October 31 renewal. General contractor licenses expire October 31 of even-numbered years. Set a reminder at least 90 days out.
• Forming an entity without naming it correctly. A name that is not distinguishable from an existing registration will be rejected, and an LLC name must include one of the required endings.

Tips for a Smoother Application

• Organize your experience proof by project. Build a folder with one sheet per project showing the dates, your role, the classification and the contract value. It makes the PQP review faster.
• Get your financial statements prepared before you buy a bond. A surety underwriter will ask for them, and clean statements can help you qualify for a better rate.
• Keep your PQP and your insurance broker in the loop. Insurance requirements can affect how you structure the business, so ask your broker to review your entity choice.
• Calendar every date. Track the October 31 license expiration, the April 30 local license due date and any bond renewal date in one place.
• Confirm open fees in writing. Exam fees, application fees and surety premiums are not all settled figures in this guide. Get the current amounts from PSI, the CLB and your surety before you commit money.

Expected Results

If you follow these steps in order, you should be positioned to bid on general contracting work at the Group and classification you selected. Many applicants find the exam and the financial proof take the longest, so plan those first. Results depend on your experience record, your financial documents and how quickly the agencies process your file, so treat any timeline as an estimate you confirm with the CLB rather than a promise.

Once licensed, you can likely expect to bid on larger jobs over time as you build a record and move up Groups. That progression depends on your work, your finances and your compliance habits, and it is not automatic.

When to Talk to a Professional

A single-owner contractor with one classification and one city may handle much of this alone. A business with several classifications, multiple Groups, employees, out of state owners or large commercial contracts should involve a qualified attorney for entity and contract questions and a CPA for tax and capital questions. A surety agent can explain bond underwriting, and your local clerk can confirm your business license class.

For official information, start with the South Carolina Secretary of State at sos.sc.gov for entity filings, the South Carolina Department of Revenue at dor.sc.gov for tax questions, and the Contractors' Licensing Board for license rules, Group requirements and renewals.
