South Carolina Contractor License Lookup: Verify LLR Status, Group Limits & Residential Board Routing
Use this guide to verify a South Carolina contractor license, understand the SC Contractor’s Licensing Board, check the $10,000 general/mechanical contractor threshold, compare license groups, avoid residential-board confusion, apply or renew through LLR, and file the right complaint if a contractor problem appears.
South Carolina contractor searches can be confusing because commercial general and mechanical contractors, residential builders, residential specialty contractors, burglar/fire alarm contractors, fire sprinkler contractors and construction managers do not all use the exact same user path. This guide puts the official routes into one practical page.
Independent guide: ContractorsBoard.org is not the official South Carolina Contractor’s Licensing Board, SC LLR, South Carolina Residential Builders Commission, or a legal service. Always verify license status, group limits, classifications, fees, renewal dates, forms, financial requirements, complaints, board orders, exams and residential-board requirements directly with SC LLR before hiring, bidding, applying, renewing or filing a complaint.
South Carolina Contractors Licensing Board quick answer: search the board, then verify the right route
The official South Carolina Contractor’s Licensing Board is under the South Carolina Department of Labor, Licensing and Regulation, commonly called SC LLR. The board regulates general and mechanical contractors, construction managers, burglar alarm and fire alarm contractors, fire sprinkler contractors, and the boiler safety program.
For general or mechanical contracting, South Carolina law says no entity or individual may practice as a contractor by performing or offering to perform covered work when the total cost of construction is greater than $10,000 without a license issued under Chapter 40-11.
A safe search is not only “active or not active.” You should verify the exact license name, license type, classification or subclassification, group financial limit, expiration date, and whether the job belongs under the Contractor’s Licensing Board or the Residential Builders Commission.
Official South Carolina sources used for this contractor license guide
This page is built around official SC LLR and South Carolina Code resources. Use it as an independent guide, but use the official board pages and license lookup tools for final action.
Contractor’s Licensing Board
Official LLR board page with contractor lookup, applications, renewals, fees, board orders, complaints, forms and contact details.
South Carolina Code Chapter 40-11
Official statutory source for licensing thresholds, definitions, group limitations, renewals, exemptions and unlicensed-contractor limits.
Residential Builders Commission
Official LLR commission for residential builders, residential specialty contractors, residential electricians, HVAC installers, plumbers and home inspectors.
South Carolina contractor license lookup: commercial board vs residential board confusion
The most common search mistake is using one South Carolina lookup for every contractor. The SC Contractor’s Licensing Board is the correct path for general and mechanical contractors under Chapter 40-11, plus other board-regulated contractor areas. Residential builder and residential specialty work may route through the Residential Builders Commission instead.
Commercial/general work
Use the Contractor’s Licensing Board route when covered general or mechanical construction is over $10,000.
Residential building
Use the Residential Builders Commission when the work is residential building, specialty contracting or home inspection under that commission.
Alarm and sprinkler work
Burglar/fire alarm and fire sprinkler contractors have dedicated lookup and board paths under the CLB site.
Construction manager
Construction manager registration has special rules and should not be treated as the same as a normal contractor lookup.

South Carolina contractor license lookup: what to verify before hiring or paying
Use SC LLR Licensee Lookup before hiring a contractor, signing a contract, paying a deposit, approving a change order or allowing work to begin. A website, truck sign, referral, social media ad or business card is not the same as an official LLR license record.
Search the exact business name and license number whenever available. Then compare the LLR record against the written contract, invoice, payment name, permit application and project scope. If the record name does not match the name used in marketing, contracts or payment requests, pause and verify with LLR.
| What to check | Why it matters | Bad sign |
|---|---|---|
| License name | South Carolina law restricts construction under a name other than the exact licensed name. | Contract, invoice or payment name differs from LLR license name. |
| License type | General, mechanical, alarm, sprinkler, residential and construction manager paths differ. | Contractor says “licensed” but cannot explain which board or type. |
| Classification/subclassification | The classification controls the kind of work the contractor can perform. | License does not match building, highway, utility, mechanical, roofing, pool or other work type. |
| License group | Groups control bidding and performing financial limits. | Project value exceeds the contractor’s group limit. |
| Expiration or lapsed status | A lapsed license creates unlicensed-practice risk. | Contractor says renewal is “in process” but cannot show active status. |
Plain-English rule: If the LLR record does not match the business name, job type and project value, do not rely on the word “licensed” until the mismatch is resolved.
South Carolina contractor license groups: financial limits for general and mechanical contractors
South Carolina license groups are not decorative. They set financial limitations for bidding and performing general or mechanical construction. A contractor can be licensed but still not hold the proper group for a larger project.
General contractor group limits
| General group | Bid/job limit | Required net worth or working capital |
|---|---|---|
| Group 1 | Not to exceed $100,000 per job | $20,000 net worth or $10,000 working capital |
| Group 2 | Not to exceed $400,000 per job | $60,000 net worth or $40,000 working capital |
| Group 3 | Not to exceed $1,000,000 per job | $150,000 net worth or $100,000 working capital |
| Group 4 | Not to exceed $3,000,000 per job | $250,000 net worth or $175,000 working capital |
| Group 5 | Unlimited | $350,000 net worth or $250,000 working capital |
Mechanical contractor group limits
| Mechanical group | Bid/job limit | Required net worth or working capital |
|---|---|---|
| Group 1 | Not to exceed $35,000 per job | $7,000 net worth or $3,500 working capital |
| Group 2 | Not to exceed $100,000 per job | $15,000 net worth or $10,000 working capital |
| Group 3 | Not to exceed $200,000 per job | $30,000 net worth or $20,000 working capital |
| Group 4 | Not to exceed $400,000 per job | $60,000 net worth or $40,000 working capital |
| Group 5 | Unlimited | $300,000 net worth or $200,000 working capital |
Do not split the job: South Carolina license groups are tied to bidding and performing limits. Trying to split one project into smaller pieces to fit a lower group can create serious licensing and contract-risk issues.
Apply for a South Carolina general or mechanical contractor license
SC LLR explains that Primary Qualifying Parties and Qualifying Parties must complete examination requirements before the entity or individual submits the application for licensure. Applicants generally must satisfy technical exam requirements, the South Carolina Business Management and Law for Commercial Contractors exam, work experience, business authorization and financial responsibility requirements.
To qualify for licensure under Chapter 40-11, an entity must be a sole proprietorship, partnership, qualifying business entity or registered out-of-state entity authorized to do business in South Carolina, and must have a certified qualifying party in a responsible management position.
| Application item | Why it matters | Mistake to avoid |
|---|---|---|
| Business authority | LLR requires verification to conduct business in South Carolina from the Secretary of State unless sole proprietorship exception applies. | Submitting a business entity that is not properly authorized in South Carolina. |
| PQP/QP certification | The Primary Qualifying Party is responsible for directing or reviewing work in the requested classification. | Not confirming the qualifying party’s certification and responsible management role. |
| Two years of work experience | LLR lists at least two years of work experience within the past five years, except waiver/reciprocity situations. | Using vague experience that does not match the classification or subclassification. |
| Technical and business-law exams | Applicants may need technical exam pass sheets and Business Management and Law exam pass sheet. | Submitting an initial application before the exam route is complete. |
| Financial statement or surety bond | Group limitations require financial proof or allowed surety bond alternative. | Requesting a group without meeting its net worth, working capital or bond requirement. |
| Licensure fee | LLR lists a $350 licensure fee for the general/mechanical application route. | Relying on old third-party fee pages instead of current LLR forms. |
South Carolina residential builders and specialty contractors: use the right LLR commission
If the job is residential, do not automatically use the commercial Contractor’s Licensing Board as the only route. The South Carolina Residential Builders Commission licenses or registers qualified individuals performing residential building, residential specialty contracting and home inspecting on residential buildings or structures not over three floors and not more than sixteen units in any single apartment building.
The Residential Builders Commission also issues residential business certificates of authorization to firms qualified to practice residential building, residential specialty contracting or home inspecting. It receives and investigates complaints involving residential building licensing and registration laws.
Residential builder license
Use the Residential Builders Commission for residential building work that falls under that commission.
Residential specialty work
Residential specialty contractor registration, residential electrician, HVAC installer/repairer and residential plumber paths are separate from commercial CLB lookup.
Home inspector and COA
Home inspector licensing and Certificate of Authorization routes are also listed under the Residential Builders Commission.
Renew a South Carolina contractor license and avoid lapsed-license problems
South Carolina contractor licenses are renewable biennially. LLR’s licensure page states that all General Contractor licenses expire October 31 in even-numbered years and all Mechanical Contractor licenses expire October 31 in odd-numbered years.
South Carolina law says renewal applications not postmarked by the expiration date result in a lapsed license. A license lapsed for failure to renew may be renewed within ninety days from expiration by filing the renewal and paying renewal and late fees. If the license is not renewed within the allowed period, the entity must meet initial licensure requirements to engage in construction.
- Check your exact expiration date in LLR online services.
- General contractor licenses expire October 31 in even-numbered years.
- Mechanical contractor licenses expire October 31 in odd-numbered years.
- Renew by the expiration date to avoid a lapsed license.
- Use the ninety-day lapsed-license route only if it applies and verify fees.
- Do not keep contracting after lapse and assume it is only a paperwork issue.
Before hiring a South Carolina contractor: license, name, group, specialty and permit checks
A South Carolina contractor license is important, but it does not replace normal project protection. Owners should verify the LLR record, written contract, insurance proof, local permits, scope, payment schedule and change-order process before work begins.
What to verify before signing
- Search the official LLR license record.
- Match the license name to the contract and payment name.
- Confirm the license type fits commercial or residential work.
- Confirm classification or subclassification matches the actual work.
- Confirm license group fits the bid or job amount.
- Ask who pulls permits and schedules inspections.
- Keep written scope, payment terms and change-order rules.
Red flags that should slow payment
- No LLR license number is provided.
- The business name differs from the LLR record.
- The job value exceeds the license group limit.
- The work type does not match the license classification.
- The contractor says residential and commercial boards are the same.
- Cash-only pressure or no written contract.
- Permit responsibility is vague or avoided.
What happens if someone performs South Carolina contractor work without the required license?
South Carolina law makes it unlawful to use the term “licensed contractor” or perform or offer to perform general or mechanical construction without first obtaining the required license. The law also restricts engaging in construction under a name other than the exact name on the license.
This matters because an entity without a valid required license may not bring an action at law or equity to enforce contract provisions. An entity that contracts under a name other than the name appearing on its license may also lose the ability to enforce the contract.
Name match risk
Marketing, advertising, site signs and contracts should use the exact licensed name unless a narrow exception applies.
Contract enforcement risk
Unlicensed entities may lose the ability to enforce contract provisions for work requiring a license.
Project withdrawal risk
Entities engaging in regulated construction without the required license or certificate may have to withdraw from the project.
File a South Carolina LLR complaint against a contractor or report unlicensed activity
Complaint users should start by identifying the correct board. If the problem involves a commercial general or mechanical contractor, use the Contractor’s Licensing Board complaint route. If it involves residential building or residential specialty contracting, use the Residential Builders Commission complaint route.
A strong complaint usually includes the license number, business name, jobsite address, contract, invoices, payment proof, photos, messages, permit details, inspection details, advertisements and a clear timeline. If the issue is mainly money recovery, bad workmanship or private damages, a board complaint may not be the only path. Civil/legal options may also matter.
| Complaint issue | Official route to review | What to prepare |
|---|---|---|
| Licensed commercial contractor | SC Contractor’s Licensing Board complaint route. | License number, business name, contract, invoices, photos, payments and timeline. |
| Unlicensed general or mechanical work | LLR lookup first, then complaint if facts support unlicensed activity. | Ads, estimate, payment proof, job value, jobsite and name used. |
| Residential builder or specialty issue | Residential Builders Commission complaint route. | Residential license/registration details, contract, photos, messages and permit facts. |
| Wrong business name | Contractor’s Licensing Board if CLB-regulated work is involved. | LLR lookup screenshot, contract name, advertising name, invoice and payment name. |
Complaint limit: A licensing complaint is not the same as a guaranteed refund, repair order or lawsuit. For major financial loss, property damage, lien disputes or breach-of-contract claims, consider legal advice in addition to LLR reporting.

Final recommendation for South Carolina contractor license users
The safest South Carolina contractor check is not simply “does a license exist?” You need to verify the correct board, exact license name, license type, classification or subclassification, group limit, expiration date, and whether the project belongs under the Contractor’s Licensing Board or the Residential Builders Commission.
Contractors should confirm PQP/QP, exam, work experience, business authorization, financial statement or surety bond, renewal and group requirements before bidding or applying. Owners should search LLR, match names, confirm scope and group limits, keep written documents and use the correct complaint route if the contractor record does not match the job.
