South Carolina Contractor License Lookup: Check the Right LLR Record Before You Hire or Pay
South Carolina uses separate licensing routes for commercial general and mechanical contractors and for residential builders and specialty contractors. Start with the correct SC LLR database, then verify the legal name, license number, status, classification and project limit before signing a contract or relying on a contractor’s claim.
This guide explains both official lookup systems, status meanings, commercial license groups, current 2026 renewal deadlines, residential rules, complaints and the fixes to try when a search returns no record.
Quick Answer: How to Check a South Carolina Contractor License
For a commercial general or mechanical contractor, use the South Carolina Contractor’s Licensing Board public search. For a residential builder, residential specialty contractor, residential electrician, residential plumber or residential HVAC contractor, use the Residential Builders Commission lookup.
Search by license number when possible. The commercial lookup instructs users to enter numbers only and leave out prefixes such as G, M, CLG or CLM. If searching by company name, do not combine the company and individual-name fields in the same search.
After locating the record, confirm the legal company or individual name, exact credential, current status, classification and any group or project limitation shown. Do not rely only on a truck decal, proposal, old license card or a contractor saying that renewal is “in process.”
If you need a broader professional-license route rather than only contractors, use the South Carolina License Verification guide to identify the correct state licensing system.
Which South Carolina Contractor Lookup Should You Use?
South Carolina does not place every construction credential in one identical search screen. The safest approach is to identify the work first and then open the board responsible for that credential.
| Work or credential | Official regulator | Best lookup | Key warning |
|---|---|---|---|
| Commercial general contractor | SC Contractor’s Licensing Board | Commercial Contractors public search | Check both classification and license group, not only “Active.” |
| Commercial mechanical contractor | SC Contractor’s Licensing Board | Commercial Contractors public search | Electrical, plumbing, HVAC, heating and other mechanical subclassifications have different scopes. |
| Residential builder | SC Residential Builders Commission | Residential Builders public search | Residential builder licensing is different from the commercial Chapter 11 license. |
| Residential specialty contractor | SC Residential Builders Commission | Residential Builders public search | Registration is limited to the classifications shown on the record. |
| Residential electrician, plumber or HVAC contractor | SC Residential Builders Commission | Residential Builders public search | Do not substitute an unrelated commercial or general license for the residential trade credential. |
| Burglar alarm, fire alarm or fire sprinkler contractor | SC Contractor’s Licensing Board | LLR Contractor’s Licensing Board resources and license lookup | These are separately regulated contractor categories. |
Both official lookup pages tell users to try the other contractor board when a search returns zero records. Check commercial and residential routes before reaching a final conclusion.
South Carolina Contractor License Lookup: Step-by-Step
Use this workflow before signing a construction contract, paying a large deposit, approving a subcontractor, reviewing a bid or accepting a contractor’s claimed license number.
Identify whether the project is commercial or residential
Commercial general and mechanical contractors generally use the Contractor’s Licensing Board lookup. Residential builders and residential specialty contractors use the Residential Builders Commission search.
Collect the strongest identifier
Ask for the exact license or registration number and legal business or individual name. A number is usually safer than a broad name search when several contractors have similar names.
Search the official LLR database
For commercial records, enter numbers only when using the license-number field. Do not include G, M, CLG or CLM. The commercial tool also advises against searching the company name and individual name at the same time.
Open the matching record and read beyond the name
Confirm status, license type, classification, city and other identifying information. For commercial contractors, review the classification and group because those fields can affect what work and project size the contractor is authorized to handle.
Match the licensed entity to the contract
The legal company or person named in the agreement should match the LLR record. A qualifying party connected to one company should not automatically be treated as proof that another company is licensed.
Save dated verification proof
Record the lookup used, date checked, legal name, license number, status, classification, group limitation and any public issue that requires follow-up before work begins.
Commercial Contractor Search Tips That Prevent False “No Record” Results
Enter numbers only
The official commercial lookup says not to enter G, M, CLG or CLM when searching by license number.
Company or individual, not both
Search either the company name or the individual’s name. Combining both can prevent the result you expect.
Use fewer letters if uncertain
A short partial name can help when the exact legal company spelling or punctuation is unclear.
Add a city
The commercial search instructions state that a city name is required when searching by classification only.
Avoid punctuation
LLR specifically tells users not to use punctuation when searching the company-name field.
Try the Residential Builders database
A residential contractor may not appear in the commercial search even though a valid residential credential exists.
SC Contractor License Status: Active, Inactive, Lapsed and Suspended
The commercial and residential databases use similar status words, but the official pages provide specific warnings about what each status means.
Commercial Contractor’s Licensing Board status
| Status | LLR meaning | What you should do |
|---|---|---|
| ACTIVE | LLR describes the contractor as current and properly licensed to work and pull permits in South Carolina. | Continue checking classification, group limit, legal entity and project scope. |
| INACTIVE | The contractor cannot bid, pull permits or perform regulated contracting work above the $10,000 commercial threshold. | Do not treat the record as an active commercial license. |
| LAPSED | The license is lapsed or cancelled and cannot be used for regulated commercial work above the threshold. | Wait for reinstatement or renewed status and verify again. |
| SUSPENDED | The license has been suspended by the Board; work and permit activity are restricted by that status. | Stop relying on the credential until LLR shows an acceptable status. |
Residential Builders Commission status
| Status | Residential lookup meaning | Practical response |
|---|---|---|
| ACTIVE | Current and properly licensed to work and pull permits. | Confirm license type and scope before contracting. |
| APPROVED | The applicant or licensee is in final stages of becoming Active. | Do not automatically treat Approved as an Active credential. |
| PENDING | The license has not been issued; the database warns that work over $500 cannot be performed under a pending credential. | Wait for issuance and recheck status. |
| INACTIVE | The licensee cannot work until the credential returns to Active status. | Do not rely on the license for current regulated work. |
| LAPSED | The credential is lapsed or cancelled; the database states work over $500 cannot be performed. | Require reinstatement or a new qualifying credential before covered work. |
| SUSPENDED | The license is suspended and no work or permits may be pulled during suspension. | Do not proceed under the suspended credential. |
| CEASE AND DESIST | The Commission has issued a Cease and Desist order. | Do not treat the contractor as cleared for work or permits covered by the order. |
South Carolina Contractor License Types and Dollar Thresholds
The phrase “contractor license” can refer to several different South Carolina credentials. Project type, total cost and residential versus commercial work all matter.
| Credential | Typical scope | Key threshold | Authority |
|---|---|---|---|
| General Contractor | Commercial/general construction under the licensed classification. | Chapter 11 requires licensure when total cost of general contracting is greater than $10,000. | Contractor’s Licensing Board |
| Mechanical Contractor | Mechanical construction such as electrical, plumbing, heating, air conditioning and other listed subclassifications. | Chapter 11 requires licensure when total cost of mechanical contracting is greater than $10,000. | Contractor’s Licensing Board |
| Residential Builder | Covered construction, repair or improvement of residential structures not over three floors and not more than sixteen units in a single apartment building. | More than $5,000 for the covered undertaking. | Residential Builders Commission |
| Residential Specialty Contractor | Specialized residential trades within the classifications held. | Residential specialty contracting definition applies to undertakings over $500 when not regulated by Chapter 11. | Residential Builders Commission |
Building permits, county or municipal business licenses and other local requirements may still apply. Residential specialty contractors are specifically not exempt from local business-license or regulatory ordinances.
Commercial License Group Limits: What Group 1–5 Means
For commercial general and mechanical contractors, the license group sets a bid and job dollar limitation. It is not simply a ranking or experience score.
| Group | General contractor limit | Mechanical contractor limit | Why it matters |
|---|---|---|---|
| Group 1 | $100,000 per bid/job | $35,000 per bid/job | A project above the limit requires a higher applicable group. |
| Group 2 | $400,000 | $100,000 | Check the group against the total project or contracting amount. |
| Group 3 | $1,000,000 | $200,000 | An Active status alone does not erase the group limitation. |
| Group 4 | $3,000,000 | $400,000 | Verify the exact classification as well as the group. |
| Group 5 | Unlimited | Unlimited | The classification still determines the type of work authorized. |
The classification tells you the type of regulated work. The group tells you the bid and job dollar limit. A contractor should satisfy both for the project you are checking.
How to Read Common SC Contractor Classification Codes
Commercial records may show classification abbreviations. The exact code matters because one commercial license does not automatically authorize every construction trade.
Building
The Building classification covers the broad general-contractor building scope described by South Carolina law, subject to exclusions and separately regulated work.
Air Conditioning
AC is a mechanical contractor classification. Verify the mechanical group and the exact scope shown in the current record.
Electrical
Electrical is a mechanical contractor classification under the commercial Contractor’s Licensing Board system.
Plumbing
Plumbing is separately classified. Do not assume another mechanical or building classification automatically covers the plumbing portion of a project.
Heating
Heating is another regulated mechanical classification. Confirm the specific license record rather than relying on a general “HVAC contractor” description.
Check the scope before paying
A contractor may be licensed in one classification but not another. Compare the record to the exact work in your written proposal.
South Carolina Contractor License Renewal: Current 2026 Deadlines
Renewal timing depends on the board and license type. A renewal receipt or submitted application should not be treated as current authority when the public database still shows an unacceptable status.
October 31, 2026 deadline
The current 2026–2028 General Contractor renewal period requires renewal by October 31, 2026. The on-time renewal fee is $135.
Late cost rises each month
Current totals are $235 during November 2026, $285 during December 2026 and $335 during January 2027. After January 31, 2027, the license lapses and reinstatement is required.
Odd-numbered expiration cycle
SC LLR states General Contractor licenses expire October 31 in even-numbered years and Mechanical Contractor licenses expire October 31 in odd-numbered years.
June 30, 2026 regular deadline passed
The 2026–2028 Residential Builder regular renewal deadline was June 30, 2026. Late renewal is currently available through June 30, 2027.
$270 during late renewal period
SC LLR lists a $220 renewal fee plus a $50 late fee for Residential Builder licenses renewed after June 30, 2026 and by June 30, 2027.
Commercial renewal needs financial support
General and mechanical contractor renewal can require an acceptable financial statement or qualifying surety bond before the online renewal process can be completed.
If you are checking a commercial general contractor near the October 31, 2026 deadline, save a fresh lookup result. A status can change when renewal requirements are not completed.
Before Hiring a South Carolina Contractor: Verification Checklist
A contractor can give you a real license number and still be the wrong company, wrong classification or wrong group for your job. Verify the complete match.
- Exact legal company or individual name.
- License or registration number.
- Commercial versus residential board.
- Current status.
- Expiration or renewal context.
- Correct construction classification.
- Commercial group limit where applicable.
- City or identifying information that matches the contractor.
- Local permit and business-license requirements.
- Date the official record was checked.
- A contractor number printed on a truck.
- An old wallet card or certificate.
- A screenshot with no current lookup date.
- Online reviews instead of state licensing status.
- A Secretary of State business record alone.
- A qualifying party’s name without matching the licensed entity.
- A license for a different construction classification.
- A “renewal submitted” email when the public record is not current.
A corporation or LLC can exist as a business entity without holding the contractor credential required for a regulated project. Contractor verification and business-entity verification answer different questions.
Applying for a South Carolina General or Mechanical Contractor License
If you searched because your own commercial contractor record does not yet exist, the initial licensure process includes more than passing an exam.
$350 license fee
SC LLR currently lists a $350 initial license fee for general and mechanical contractor licensure.
Two years within the past five
A primary or qualifying party generally must document at least two years of applicable work experience performed within the past five years, except where a waiver or reciprocity route applies.
Technical + SC business law where required
Applicants may need the applicable technical examination and the South Carolina Business Management and Law for Commercial Contractors examination.
Financial statement or surety bond
The requested group limitation is supported through the applicable financial documentation or surety-bond option.
South Carolina business authority may be needed
The initial application requires verification to conduct business in South Carolina when applicable; the Board notes an exception for sole proprietorships.
The company and qualifier are linked
Commercial contractor licensure uses primary qualifying party and qualifying party certifications. Verify that the active licensed entity is the entity actually contracting for the project.
South Carolina Contractor Complaints and Discipline
A license lookup answers whether the credential is current. A complaint is a separate process used when conduct may violate licensing law or when unlicensed activity is alleged.
Contractor’s Licensing Board
The Board can investigate licensing-law violations and take disciplinary action such as a reprimand, fine or license action. Its complaint process is not a substitute for resolving every contract or monetary dispute.
- Keep a copy of the signed contract.
- Keep the building permit when applicable.
- Keep invoices, photographs and written communications.
- Describe the alleged licensing or construction-standard issue clearly.
Residential Builders Commission
The Commission accepts complaints against licensees and unlicensed persons when the activity falls under its jurisdiction. Supporting records help the agency determine whether an investigation is appropriate.
- Include contracts and relevant project documents.
- Include permit or occupancy records when relevant.
- Provide invoices, estimates or cancelled checks that connect the respondent to the project.
- Include a right-to-cure letter when the project requires one.
The statewide licensing complaint system explains that LLR investigates administrative and licensing violations but cannot award monetary restitution on a complainant’s behalf. Civil or contractual remedies may require a different route.

South Carolina Contractor License Lookup FAQs
How do I look up a South Carolina contractor license?
Use the South Carolina LLR public lookup that matches the contractor type. Commercial general and mechanical contractors use the Contractor’s Licensing Board search, while residential builders and residential specialty contractors use the Residential Builders Commission lookup.
Can I search an SC contractor by license number?
Yes. The commercial lookup allows license-number searches and instructs users to enter numbers only without prefixes such as G, M, CLG or CLM. The residential lookup also instructs users to enter numbers only when searching by license number.
Why does my South Carolina contractor search show zero records?
You may be using the wrong board, the business may be licensed under a different legal name, punctuation may interfere with a company-name search, or the license number may have been entered with letters. Try the other official contractor database and search again using the legal name or numbers-only license search.
What does Active mean in the SC contractor lookup?
The official commercial and residential lookup pages describe Active licensees as current and properly licensed. You should still confirm that the classification, license group or residential credential matches the work being offered.
What does Lapsed mean for a South Carolina contractor?
A lapsed record is not a current active credential. The commercial lookup states that a lapsed contractor cannot perform regulated contracting work above the commercial threshold, while the residential lookup states that a lapsed licensee cannot perform work over $500 under that credential.
When is a commercial contractor license required in South Carolina?
South Carolina law requires a Chapter 11 contractor license when the total cost of regulated general contracting or mechanical contracting is greater than $10,000. The classification and license group must also fit the work and project amount.
When does a South Carolina residential builder need a license?
South Carolina defines a residential builder as a person who performs or offers covered residential construction, repair or improvement work on qualifying residential structures when the cost of the undertaking exceeds $5,000.
What do South Carolina contractor license groups mean?
Commercial General and Mechanical Contractor Groups 1 through 5 determine the bid and job dollar limit. For example, General Contractor Group 1 is limited to $100,000 per bid or job, while Group 5 is unlimited. Classification still determines the type of work authorized.
When do South Carolina General Contractor licenses renew in 2026?
The current 2026–2028 General Contractor renewal period has an October 31, 2026 on-time deadline and a $135 renewal fee. Late fees increase during November, December and January, and licenses not renewed by the end of the late period lapse.
How do I file a complaint against a South Carolina contractor?
Use the complaint process for the board that regulates the contractor. Commercial general and mechanical contractor complaints go through the Contractor’s Licensing Board, while residential builder and specialty-contractor complaints use the Residential Builders Commission process. Include relevant contracts, permits, invoices, photographs and other supporting records.
Check the License Before the Contract, Deposit or Permit
Start with the correct SC LLR contractor database, search by license number when possible, and read the entire record rather than stopping at a matching name. For commercial contractors, verify both classification and group limit. For residential work, confirm that the credential is Active and covers the trade or building work involved.
If the record is inactive, lapsed, suspended, pending or subject to a cease-and-desist status, resolve the issue in the official LLR system before relying on the contractor for regulated work.
