South Carolina · Concrete licensing · official-source guide
South Carolina licenses concrete work through two agencies. The South Carolina Contractor's Licensing Board issues the General Contractor Concrete (CT), Masonry (MS) and Concrete Paving (CP) subclassifications for commercial construction over $10,000. The Residential Builders Commission registers masons doing residential concrete and masonry over $500. Both require verified work experience before the state issues any credential.

South Carolina splits concrete contracting between two state agencies, and the dividing line is the type of building, not the size of the pour. The South Carolina Contractor's Licensing Board, part of the Department of Labor, Licensing and Regulation, handles commercial work. Section 40-11-30 of the state code says no entity may perform or offer to perform general contracting work with a total cost of construction greater than $10,000 without a license from that board. A 2023 amendment raised that figure from $5,000, so older guidance you find online is out of date. The Residential Builders Commission handles residential buildings not over three floors in height with no more than sixteen units in any single apartment building. On the residential side the thresholds are lower. A residential specialty contractor must register once an undertaking exceeds $500. A residential builder license is required once the cost of the undertaking exceeds $5,000. Both agencies sit at the state level, so there is no county concrete license to chase and no city concrete exam to pass. Cities and counties still charge a business license and still issue the building permits, and both statutes order permit officials to refuse a permit unless the applicant shows the state credential first. A concrete crew that pours driveways for homeowners, slabs for a licensed builder and footings for a commercial shell can need credentials from both agencies at the same time. Deciding which one you need starts with the building, then the dollar value, then the specific subclassification that matches the work you sell.

The Concrete subclassification sits under General Contractors-Specialty in Section 40-11-410 and carries the abbreviation CT in the state license file. Its written scope is wide. The statute covers all work in connection with concrete forming and placing, assembling of forms, molds, slipforms and pans, and centering. It covers trenching, excavating, backfill and grading when that work is in connection with concrete construction. It covers construction of sidewalks, driveways, curbs, medians and barrier walls. It covers installing embedded items essential to or comprising an integral part of concrete construction, including reinforcing elements and accessories, and it names concrete chimneys, floors, piers and foundations built with concrete rebar and other materials common to the concrete industry. Two carve-outs matter when you bid. The Concrete subclassification does not include the General Contractor-Highway-Bridge subclassification. It also does not include construction of streets, roads, parking lots and highways, which belong to Concrete Paving. A flatwork contractor holding CT can pour a building slab, a sidewalk and a loading dock, but cannot take the parking lot in the same bid package on that credential alone. Concrete appears on the board's published list of classifications that require a technical examination through PSI. That makes CT more work to obtain than the neighboring Masonry credential, and it is the reason some South Carolina firms whose work is footings and slabs hold Masonry instead. Read the statutory scope against your own estimate sheet before you apply, because the board confines a licensee to the limitations of the classifications it actually holds.
Masonry is the other Specialty subclassification that reaches poured concrete, and both boards define it in nearly identical words. Section 40-11-410 describes Masonry as the installation, alteration and repair of poured-in-place concrete foundations, with footings and reinforced slabs given as the examples, plus brick, concrete block and products common to the masonry industry, including mortarless types and synthetic masonry products. The Residential Builders Commission uses the same wording for its Masons trade classification, which it attributes to Regulation 106-1. The practical difference between Masonry and Concrete is the examination. The Contractor's Licensing Board lists Masonry among the General Contractor classifications with no technical exam. An applicant for Masonry passes only the South Carolina Business Management and Law for Commercial Contractors exam and files a Work Experience Affidavit showing two years of work performed within the past five years. An applicant for Concrete sits a PSI technical exam on top of that. Masonry carries the abbreviation MS in the public license file. If your commercial work is footings, stem walls, reinforced slabs, block and brick, Masonry may match what you actually sell. If you also form and place site concrete such as curbs, medians, barrier walls and sidewalks, the Masonry scope does not reach it. Holding both is allowed. Section 40-11-270 lets one entity be licensed in more than one classification or subclassification once all qualifications are met, and the board accepts more than one subclassification on the same application form.

Concrete Paving is a subclassification of General Contractors-Highway rather than of Specialty, and that placement tells you how the board thinks about it. Section 40-11-410 defines Concrete Paving as the construction, rehabilitation and repair of concrete streets, roads, highways, driveways, parking lots, airport runways and aprons, plus concrete work incidental to those, naming sidewalks, curbs, medians and barrier walls. The subclassification also includes work under the Grading subclassification, so a paving licensee can do its own soil preparation without a second credential. The abbreviation in the license file is CP. Commercial parking lots are the usual reason a flatwork company needs this one. A driveway at an owner-occupied house falls on the residential side and under the residential thresholds, but a parking lot at a retail center with a total cost of construction over $10,000 is commercial paving. Concrete Paving requires a technical exam through PSI. The related Asphalt Paving subclassification covers asphalt streets, roads, driveways and parking lots and also reaches concrete curbs and gutters, which is worth knowing when you subcontract to an asphalt firm. The full Highway classification is not a shortcut around the exams. The board states that Highway requires passing the exams for Bridges, Concrete Paving, Asphalt Paving and Grading. Section 40-11-300 also makes it unlawful for an owner, construction manager or prime contractor to divide work into portions so as to avoid the classification or license group requirements, and it says the total cost of construction determines the group for the project.
On the residential side, a concrete and masonry crew usually registers rather than tests. Section 40-59-20 defines a residential specialty contractor as an independent contractor who contracts with a licensed residential builder, a general contractor or an individual property owner to do construction work, repairs, improvement or reimprovement requiring special skills and specialized trades, when the undertakings exceed $500 and are not regulated by Chapter 11 of Title 40. The statute names masons among the trades that are issued registrations rather than examined specialty licenses, and the Residential Builders Commission confirms that no examination is required to become a registered specialty contractor. The Masons trade classification covers poured-in-place concrete foundations such as footings or reinforced slabs, brick, concrete block and masonry products. Three limits shape how the registration can be used. A registration may cover no more than three trade classifications, and Section 40-59-240 says anyone who wants more than three must be examined and licensed as a residential builder. A registrant may not undertake work outside the scope of the registration, including hiring or subcontracting others to perform that work on its behalf. A residential specialty contractor is also not authorized to construct additions to residential buildings without supervision by a residential builder or another appropriately licensed person or entity. The Commission lists the registration fees as a $100 application fee, a $100 renewal fee, a $20 renewal late fee and a $290 reinstatement fee. Trade classifications can be changed, but only during the renewal period.
Once a residential job exceeds $5,000, the work belongs to a licensed residential builder. Section 40-59-20 defines a residential builder as one who constructs, superintends, or offers to construct or superintend the construction, repair, improvement or reimprovement of a residential building not over three floors in height with no more than sixteen units in any single apartment building, when the cost of the undertaking exceeds $5,000. A concrete contractor who wants to take whole foundation packages directly from homeowners, or who needs more than three trade classifications, applies here instead of registering as a specialty contractor. Section 40-59-220 sets a minimum of one year of actual experience under the supervision of a licensed residential builder or another appropriately licensed professional as the prerequisite for taking the examination, and requires an executed bond in the sum of not less than $15,000 or proof of financial responsibility acceptable to the commission. The Commission publishes the fees as a $135 application fee, a $220 license fee, a $220 renewal fee, a $50 renewal late fee and a $480 reinstatement fee. A builder licensed by examination in South Carolina may perform work in the specialty areas as well. Firms need a separate credential. Section 40-59-410 requires a residential business certificate of authorization for practice through a firm or under a fictitious name, with a surety bond of $15,000 and an application and annual renewal fee of $100, unless the individual practices in their own licensed name or holds at least fifty-one percent of the firm and is its sole resident licensee.
Commercial licenses in South Carolina are issued to an entity, but they are earned by a person. The Contractor's Licensing Board requires an applicant to designate a Primary Qualifying Party for each classification or subclassification it wants. The board defines the Primary Qualifying Party as the principal individual responsible for directing or reviewing work performed by the applicant in that classification. Additional qualifying parties are individuals who have met the same exam requirements without being designated as the primary. The sequence matters and trips up applicants: the qualifying party must finish the exam requirements before the entity submits its license application. For a concrete or masonry credential, the board requires at least two years of work experience performed within the past five years for each requested classification or subclassification, documented on a Work Experience Affidavit supplied with the application. Waiver and reciprocity applicants are excepted from that submission. The board says experience should be primarily commercial unless the classification specifically allows otherwise, and it notes that only the Nonstructural Renovation classification may be supported entirely by residential experience. Supervisors are told to submit the hands-on work they supervised employees performing in the field, not office management. Transfers are possible: a qualifying party certification that is current, or inactive for less than four years, moves to a new license on a transfer form, while one inactive longer than four years is handled as an initial application. On the residential side the Commission verifies and approves work experience before an applicant is made eligible for the examination.
Every commercial applicant takes at least one exam. The Contractor's Licensing Board requires all individuals to pass the South Carolina Business Management and Law for Commercial Contractors exam before requesting qualifying party certification, regardless of how they are applying. That exam and the technical exams are delivered by PSI, and the board states there are no pre-approvals required to schedule a PSI exam, so a candidate can register directly at PSI's South Carolina contractor page. Study material is published by PSI in its Candidate Information Bulletin. Which technical exam you owe depends on the subclassification. The board's published list of General Contractor classifications requiring a technical exam includes Concrete and Concrete Paving. The board's list of classifications with no technical exam includes Masonry, alongside Boring and Tunneling, Highway Incidental, Miscellaneous Metals and Railroad Lines. A Masonry applicant therefore passes the business and law exam and files the Work Experience Affidavit. A Concrete applicant does both and sits the technical exam. The board also points to two national exams for contractors licensing in multiple states, the National Commercial Building Contractor exam and the NASCLA Accredited Trade Examination for Electrical Contractors, with NASCLA transcripts sent directly to the board. On the residential side, Section 40-59-220 allows re-examination after payment of an additional examination fee, but an applicant who fails three times must wait twelve months before being examined again. That waiting period is a reason to treat the first attempt seriously rather than as a trial run.
A South Carolina commercial license carries a bid limit, and the limit comes from money rather than skill. Section 40-11-260 sets five license groups for general contractors, and an applicant must file an acceptable financial statement with a balance sheet dated no more than twelve months before the application. Group One allows bids and jobs not to exceed $100,000 per job and requires net worth of $20,000 or working capital of $10,000. Group Two allows up to $400,000 per job on net worth of $60,000 or working capital of $40,000. Group Three allows up to $1,000,000 per job on net worth of $150,000 or working capital of $100,000. Group Four allows up to $3,000,000 per job on net worth of $250,000 or working capital of $175,000. Group Five is unlimited and requires net worth of $350,000 or working capital of $250,000. The documentation tightens as the group rises. Groups One and Two accept an owner-prepared statement on a board form with an affidavit of accuracy. Group Three and Group Four require a statement compiled by a licensed certified public accountant on initial application. Group Five requires an audited balance sheet initially and a reviewed statement on renewal. Moving up means meeting the higher group's requirements, and the board may order additional financial information and downgrade a license if it believes the minimums are no longer met. A licensee that bids past its group limit can be penalized under Section 40-11-280.

South Carolina gives commercial contractors a way around the accountant. Section 40-11-262 lets an applicant provide a surety bond instead of a financial statement, from a surety authorized to transact surety business in the state, in the same amount as the net worth required for the applicant's license group. A 2023 amendment reduced that from twice the required net worth. The bond must be continuous, must list the State of South Carolina as obligee, and must benefit any person damaged by a breach of a construction contract or an unlawful act or omission in performing construction. It can only be canceled on thirty days notice to the board, and after cancellation the licensee has ten days to prove net worth or the license is suspended. On the residential side, a residential builder files a bond of not less than $15,000 or proof of financial responsibility, and Section 40-59-240 requires a registered residential specialty contractor to obtain an executed bond with a surety in an amount approved by the Commission once the total cost of materials and labor for an undertaking performed for an individual property owner exceeds $5,000. The Commission requires a current bond on file before a residential builder renews online. Neither chapter sets a general liability minimum. Workers compensation is governed separately: Section 42-1-360 exempts an employer who regularly employs fewer than four employees in the same business in the state, or whose total annual payroll the previous calendar year was under $3,000.

The commercial fee schedule is short. The Contractor's Licensing Board lists a General and Mechanical Contractor initial license fee of $350 and a biennial renewal fee of $135. Late renewal is tiered: renewed or postmarked on or before October 31 costs $135; November 1 through November 30 adds a $100 late fee for $235; December 1 through December 31 adds $150 for $285; January 1 through January 31 adds $200 for $335. Reinstatement is $350. A replacement certificate is $10 and a replacement license is $5. General Contractor licenses expire October 31 in even-numbered years, and Mechanical Contractor licenses expire October 31 in odd-numbered years, so a concrete licensee renews on the even-year cycle. Section 40-11-250 says all licenses may be renewed biennially, that a renewal application not postmarked by the expiration date results in a lapsed license, and that an entity which fails to renew and keeps building is practicing without a license. A lapsed license may be renewed within ninety days of expiration with renewal and late fees, and approval is retroactive to the expiration date. On the residential side the Commission renews residential builders, home inspectors and certificates of authorization by June 30 of the even year, charges $220 to renew a residential builder license, adds a $50 late fee during the following year, and requires a reinstatement application after that. Specialty registration renewal is $100 with a $20 late fee.

An out-of-state concrete contractor does not always start over. Section 40-11-290 allows the Contractor's Licensing Board to grant a license or certificate to an applicant holding a license in good standing in another state whose requirements are equal to or greater than South Carolina's, if the board has authorized an exam waiver agreement with that state. The statute goes further: an applicant may be exempt from the technical examination if the applicant can verify passing an examination in another state that is essentially the same as the one South Carolina requires, even without a reciprocal agreement. An applicant using this route may still be required to pass the South Carolina Commercial Contractors Business, Law and Project Management examination and must meet all other licensing requirements. The board sets conditions in practice. Waiver applicants must hold a license in good standing in a jurisdiction that administered the reciprocating exam, must have the other state's board complete an Examination Waiver form and mail it in, and may not use a license that was itself obtained by waiver or grandfathering. If the state is listed but the classification is not, the applicant is not eligible by waiver. Residential builders have their own path. The Commission waives the technical portion for a currently licensed South Carolina General Contractor with the Building or Limited Building classification, for licensees of Alabama, Georgia, Mississippi or North Carolina who were examined, and for applicants who passed the NASCLA Commercial General Building Contractor exam within the past three years. Work experience and the business and law portion still apply.
South Carolina attaches both criminal and commercial consequences to unlicensed contracting. Under Section 40-11-200, a person who practices or offers to practice in violation of Chapter 11, or who knowingly submits false information to obtain a license, is guilty of a misdemeanor and on conviction must be imprisoned not more than one year or fined not more than $5,000. The same section makes it a violation for an awarding authority, owner, contractor or their agent to consider a bid, sign a contract or allow a contractor to begin work before the required license is obtained, and it blocks a bid from being reconsidered or resubmitted if the bidder was unlicensed when the bid went in. Section 40-11-300 orders an unlicensed entity to withdraw immediately from the project and bars it from acting as a subcontractor there. The department can also issue administrative citations and penalties against unlicensed contractors under Section 40-11-100, capped at $500 for a first violation of a provision, $1,000 for a second within five years, and no more than $2,500 in administrative penalties per day. The contract consequence bites hardest. Section 40-11-370 says an entity without a valid license may not bring an action at law or in equity to enforce a contract. On the residential side, Section 40-59-30 makes unlicensed residential building or specialty contracting a misdemeanor punishable by a fine of not less than $500 and not more than $10,000 or at least thirty days imprisonment, and bars the offender from filing a mechanics lien.
The state credential is not the only paper a concrete company carries. Section 40-59-240 says residential specialty contractors are not exempt from complying with county and municipal business license ordinances or other regulatory ordinances, and that a county or municipality may require a specialty contractor to be examined and licensed under its own standards, with one protection: if the contractor has passed an examination in that area of contracting approved by the Commission, no additional examination may be required locally. Business license taxes themselves are standardized statewide. Section 6-1-400 requires a business license to be issued for a twelve-month period beginning May 1 and ending April 30, and says a license issued on a construction contract expires at the completion of the construction project. Renewal is due before May 1, and a jurisdiction may impose penalties if the tax is not paid by then. The tax is computed on gross income, and a business license related to construction contract projects may be issued on a per project basis at the taxpayer's option. Contractors working in Charleston, Columbia, Greenville, North Charleston and Mount Pleasant should note two provisions that reduce double payment and paperwork: gross income taxed by another jurisdiction is deducted when computing the tax where you are domiciled, and every taxing jurisdiction must accept the standard business license application established by the Director of the Revenue and Fiscal Affairs Office. Each jurisdiction adopts the Standardized Business License Class Schedule by ordinance, keyed to North American Industry Classification System codes.
South Carolina regulates contractor advertising through names rather than license numbers, and concrete contractors get this wrong often. Section 40-11-370 makes it unlawful to use the term "licensed contractor" or to perform or offer to perform general or mechanical construction without a license. It then makes it unlawful to engage in construction under any name other than the exact name that appears on the license, and it defines engaging in construction to include marketing, advertising, using site signs and submitting contracts. One narrow exception follows: the requirement does not include advertising on vehicles, which may use an abbreviated version of the license name as long as the advertising is not misleading. So your website header, your yard signs and your contracts should carry the exact licensed entity name, while a truck wrap may shorten it. The penalty is commercial as well as regulatory. An entity that contracts in a name other than the one on its license may not bring an action at law or in equity to enforce that contract. Chapter 11 does impose a license number display rule, but only on mechanical contractors licensed in air conditioning, heating or packaged equipment, who must display the license at the principal place of business and put the number on commercial vehicles, invoices and proposal forms. That rule does not reach concrete, masonry or paving licensees. Permits are a separate display point: Section 40-11-420 requires the sole prime contractor to pull the permit in the name on its license.

South Carolina publishes a free license lookup, and a concrete contractor should treat it as a sales asset rather than a compliance chore. The Department of Labor, Licensing and Regulation runs a Licensee Lookup main menu that lists every board it regulates. Commercial concrete credentials are under Contractors. That search screen lets anyone search by company or last name, first name, license number, city, state abbreviation and classification, and the classification menu is where the abbreviations become useful to a buyer: Concrete appears as CT, Masonry as MS, Concrete Paving as CP, Asphalt Paving as AP and Grading as GD. Residential credentials are under Residential Builders, where the license type menu includes Home Builders, RB Exam Waiver, Residential Non Mechanical Specialty, Home Inspector and COA. The residential screen even tells searchers that a zero-record result may mean the firm is listed under commercial contractors instead. The board also publishes board orders and offers bulk online verification. Two practical uses follow. First, point prospects at the lookup in your own words, naming your exact licensed entity name and classification so the search returns you on the first try. Second, run the search on every subcontractor before you sign. Section 42-1-415 relieves a higher tier contractor of workers compensation liability only when it collected documentation of coverage on a standard form at the time the subcontractor was engaged, and a contractor who falsely documents coverage faces license revocation for two years.

These are common details other guides publish about South Carolina, but we could not verify them from the agency source. Confirm them directly before relying on them.
Usually yes. The Residential Builders Commission requires a residential specialty contractor to register once an undertaking exceeds $500, and masons are a registered trade covering poured-in-place concrete foundations, brick and block. Above $5,000 for the undertaking, the work belongs to a licensed residential builder under Section 40-59-20.
Either can fit, so compare the exams. Section 40-11-410 puts poured-in-place concrete foundations, footings and reinforced slabs inside Masonry, which the board lists as having no technical exam. Concrete reaches forming, placing, curbs, medians and sidewalks but requires a PSI technical exam plus the business and law exam.
Yes. The Contractor's Licensing Board lists Concrete and Concrete Paving among the General Contractor classifications requiring a technical examination through PSI. Every applicant also passes the South Carolina Business Management and Law for Commercial Contractors exam. No pre-approval is needed to schedule a PSI exam, so you can register directly.
Not on the Concrete subclassification alone. Section 40-11-410 states that Concrete does not include construction of streets, roads, parking lots and highways, which fall under Concrete Paving. Section 40-11-270 allows one entity to hold more than one subclassification, and the board accepts both on the same application form.
Three. Section 40-59-240 limits a residential specialty registration or certificate to no more than three classifications, and anyone wanting more must be examined and licensed as a residential builder. The Commission allows trade classifications to be changed, but only during the renewal period rather than mid-term.
It depends on the credential. Commercial applicants may file a surety bond under Section 40-11-262 instead of a financial statement, in the same amount as their license group net worth. Residential builders file a bond of not less than $15,000, and registered specialty contractors bond jobs for property owners over $5,000.
Section 40-11-260 ties bid limits to finances. Group Two allows jobs up to $400,000 on net worth of $60,000. Group Three allows up to $1,000,000 on net worth of $150,000 and requires a CPA-compiled statement initially. Group Four reaches $3,000,000, and Group Five is unlimited.
General Contractor licenses expire October 31 in even-numbered years, and Mechanical Contractor licenses expire October 31 in odd-numbered years. Section 40-11-250 allows biennial renewal, treats a renewal not postmarked by the expiration date as a lapse, and permits renewal within ninety days of expiration with late fees applied.
Possibly. Section 40-11-290 allows a license where the board has an exam waiver agreement, or where you verify passing an essentially equivalent examination elsewhere. The board requires the other state to complete its Examination Waiver form, and excludes licenses obtained by waiver or grandfathering. The business and law exam may still apply.
Section 40-11-200 makes it a misdemeanor punishable by up to one year of imprisonment or a fine up to $5,000. The department can also cite unlicensed contractors administratively. Worse commercially, Section 40-11-370 bars an unlicensed entity from suing to enforce its contract, so collection becomes very difficult.
Not for concrete work. The display rule in Section 40-11-270 applies to mechanical contractors in air conditioning, heating or packaged equipment. Concrete contractors face a naming rule instead: Section 40-11-370 requires the exact license name in marketing, advertising, site signs and contracts, while vehicles may use an abbreviated version.
