South Carolina · Electrical licensing · official-source guide
South Carolina splits electrical licensing across two boards inside the Department of Labor, Licensing and Regulation. The Contractor's Licensing Board licenses the business as a mechanical contractor in the Electrical subclassification for work over $10,000, backed by a certified individual qualifying party. The Residential Builders Commission licenses the individual as a Residential Electrician for residential work over $500.

South Carolina does not run a single electrical board. It runs two contractor boards inside the Department of Labor, Licensing and Regulation, and electrical work crosses both. Section 40-11-30 says no entity or individual may practice as a contractor by performing or offering to perform contracting work for which the total cost of construction is greater than ten thousand dollars for general contracting or greater than ten thousand dollars for mechanical contracting without a license. Act No. 69 of 2023 raised both figures from five thousand dollars. Electrical is a mechanical contractor subclassification under Section 40-11-410(5)(d), so commercial electrical work above $10,000 is a Contractor's Licensing Board matter. Below that, the Residential Builders Commission picks it up. Section 40-59-20(7) defines a residential specialty contractor as an independent contractor who contracts with a licensed residential builder, general contractor, or individual property owner to do work requiring special skills when the undertakings exceed five hundred dollars and are not regulated by Chapter 11. Electricians appear at 40-59-20(7)(b), and the statute says plumbers, electricians, and heating and air conditioning installers and repairers must be issued specialty contractor licenses after passing the required examination. Act No. 186 of 2022 raised that trigger from two hundred dollars to five hundred dollars. The Residential Builders Commission states the split in plain words on its own page: residential electrical work exceeding $500 requires a license, and commercial electrical work exceeding $10,000 goes to the Contractor's Licensing Board. Section 40-59-270 closes the loop by exempting a mechanical contractor from the residential specialty contractor rules when engaged in contracting in the classification in which he is licensed.
Section 40-11-10(A) creates the South Carolina Contractor's Licensing Board under the administration of the Department of Labor, Licensing and Regulation. Subsection (B) sets nine members appointed by the Governor, seven of whom must be licensed contractors. One of those seven must have as the larger part of his business the performance of electrical work. Another must have as the larger part of his business the performance of heating, plumbing, or air conditioning work, and one each must represent highways, public utilities, commercial and industrial buildings, burglar or fire alarm systems, and fire sprinkler systems. Two members are consumer members representing the public at large. Members serve five year terms under subsection (C). The board regulates general and mechanical contractors, construction managers, burglar alarm and fire alarm contractors, fire sprinkler contractors, and the boiler safety program. The license itself attaches to an entity. Section 40-11-20(8) defines entity to include a sole proprietorship, partnership, limited liability partnership, limited liability company, association, joint venture, cooperative, or corporation, and 40-11-20(14) defines licensee as an entity that has been issued either a general or mechanical contractor's license. The individual credential inside that license is the qualifying party. The board office sits at 110 Centerview Drive, Columbia, with mail to PO Box 11329, Columbia, SC 29211, and the published contact is contact.clb@llr.sc.gov and (803) 896-4686.
Section 40-11-410(5)(d) writes the scope out at length. The Electrical subclassification covers the installation, alteration, or repair of wiring related electrical material and equipment used in the generating, transmitting, or utilization of electrical energy less than six hundred volts, including all overhead electrical wiring on public rights-of-way for signs and street decorations and all underground electrical distribution systems of less than six hundred volts serving private properties. It names panels, controls, conductors, conduits, cables, devices, plates, electric ceilings, control wiring, electric heating, lighting fixtures, lamps, general outside lighting, and underground and overhead feeder distribution systems for services. It allows installing window or through-the-wall air conditioning units not to exceed three HP or three tons where no piping is necessary. General outside lighting under this subclassification is limited solely to within property lines and not on public easements or rights-of-way. The subclassification also includes the design, installation, and servicing of fire alarm systems and all lighting on private property, athletic fields, stadiums, and parking lots. The line that matters most for bidding is this one: a contract that contains electrical work above fifty volts must be performed by a contractor licensed under this subclassification or a licensed public electrical utility contractor. Work on public easements and rights-of-way, including pole erection, tower line erection, street lighting, and primary metering, sits in the separate General Contractor Public Electrical Utility subclassification at 40-11-410(4)(m). Section 40-11-360(11) adds that sign and billboard work is exempt from the chapter, but an electrical license is required to perform a final connection to a branch circuit conductor.

Section 40-11-20(23) defines a qualifying party as an individual who has been issued a certificate to qualify an entity for a license by way of examination in a license classification or subclassification. Section 40-11-20(21) defines the primary qualifying party as the qualifying party designated by a licensee as the principal individual responsible for directing or reviewing work performed by the licensee in a particular classification. The board's licensure page requires applicants to designate a primary qualifying party for each classification or subclassification sought, and says primary qualifying parties must complete the exam requirements for certification before the entity or individual submits an application for licensure. Experience is checked at the individual level. The board requires at least two years of work experience performed within the past five years for the requested license classification or subclassification, and says that unless specifically listed, experience should include primarily commercial work experience. Waiver and reciprocity applicants are exempt from that experience filing. The initial entity application is Doc. 165 and the qualifying party application is Doc. 168. A qualifying party certification that is current, or has been inactive for less than four years, transfers to a new license on Doc. 181. A certification inactive for more than four years goes back to Doc. 168. An individual acting as a dual qualifying party for two licensed entities files Doc. 173. Under Section 40-11-110(A)(22), attempting to serve as primary qualifying party while serving house arrest, a jail sentence, or a prison sentence is a disciplinary matter.
Every route to a Contractor's Licensing Board license runs through the South Carolina Business Management and Law for Commercial Contractors exam. The board's licensure page states that regardless of how you are applying for licensure, all individuals must pass that exam before requesting qualifying party certification. Electrical then sits on the board's list of Mechanical Contractor classifications that also require a technical examination, alongside Air Conditioning, Heating, Lightning Protection, Packaged Equipment, Plumbing, Process Piping, and Refrigeration. PSI is the board's testing provider, and candidates register directly at the PSI South Carolina contractor page. The board notes that there are no pre-approvals required to schedule the PSI exams, so a candidate can test before the application goes in. Two national exams are recognized for people licensing in more than one jurisdiction: the National Commercial Building Contractor exam and the NASCLA Accredited Trade Examination for Electrical Contractors. NASCLA transcripts go directly from NASCLA to the board. There is a third route into the Electrical classification that is specific to this state. A current Master Electrician Certification issued by examination between December 1990 and December 2025 by the Municipal Association of South Carolina, or issued after January 1, 2026 by Carolinas AGC, corresponds to the Electrical classification. As of January 1, 2026, Carolinas AGC is the South Carolina Mechanical Trades Certification Program provider, and holders of older MASC certifications obtain a certification verification letter from CAGC.

A mechanical contractor license carries a group number, and the group caps what you can bid and build on a single job. Section 40-11-260(B) and the board's published table set five mechanical groups. Group 1 caps bids and jobs at $35,000 and requires net worth of $7,000 or working capital of $3,500. Group 2 caps at $100,000 against net worth of $15,000 or working capital of $10,000. Group 3 caps at $200,000 against net worth of $30,000 or working capital of $20,000. Group 4 caps at $400,000 against net worth of $60,000 or working capital of $40,000. Group 5 is unlimited and requires net worth of $300,000 or working capital of $200,000. An applicant meets one of the two tests, not both. Groups 1 and 2 may file an owner prepared financial statement on Doc. 172 with an affidavit of accuracy. Groups 3 and 4 need a statement compiled by a licensed CPA under GAAP at initial application. Group 5 needs an audited balance sheet at initial application and a reviewed statement at renewal. In place of the financial statement, Section 40-11-260 allows a surety bond in the same amount as the required net worth or working capital for the group. Act No. 69 of 2023 cut that from two times the required net worth. The published mechanical bond amounts are $7,000 for Group 1, $15,000 for Group 2, $30,000 for Group 3, $60,000 for Group 4 and $300,000 for Group 5. The bond must be continuous, must list the State of South Carolina as obligee, and may be cancelled only on thirty days notice to the board.
The Contractor's Licensing Board publishes a short fee schedule. The general and mechanical contractor initial license fee is $350. General contractor licenses expire October 31 of every even-numbered year and mechanical contractor licenses expire October 31 of every odd-numbered year, so an Electrical subclassification licensee renews on the odd-year cycle. The biennial renewal fee is $135 if renewed or postmarked on or before October 31. After that the board stacks a late fee on top: $100 for November, taking the total to $235, $150 for December, taking it to $285, and $200 for January, taking it to $335. Reinstatement is $350. A replacement certificate is $10 and a replacement license is $5. The renewal is not a fee-only transaction. The board requires an acceptable financial statement with a balance sheet dated no more than twelve months before the renewal application, or a valid surety bond or surety bond continuation certificate, submitted through the document submission portal before the online renewal system will open. The board states there is no grace period for filing that financial documentation later. Surety bonds payable to the South Carolina Residential Builders Commission are not accepted by the Contractor's Licensing Board, which matters for anyone holding both credentials. At the time of writing the board's renewal page states that mechanical contractor license renewals for the 2027-2029 period will open in August 2027.
The second credential is issued by the South Carolina Residential Builders Commission, also inside LLR, at 110 Centerview Drive, Columbia, reachable at Contact.RBC@llr.sc.gov and (803) 896-4696. Regulation 106-1(b) sets the scope of the electrician classification as the installation, alteration and repair of any wiring, related electrical material and equipment common to the residential building industry. Regulation 106-2(c) made examination mandatory for electricians effective July 1, 2004. Unlike siding installers, masons, drywall installers, carpenters, stucco installers, painters and solar panel installers, who receive registrations, electricians receive a license after passing the exam. The experience bar is set in the commission's own application package: an applicant must show a minimum of one year of residential electrical experience performed within the past five years, documented with copies of W2s or 1099s and a Residential Electrician Experience Affidavit completed by each supervisor or employer listed. Where documentation cannot be produced, the applicant submits a written explanation for the commission to weigh. Section 40-59-250 also requires a credit report, and the application package requires one dated no more than thirty days before the application. Company information is required only if the licensee intends to operate under a company name, and the applicant must own at least 51 percent of that company to list it on the license. An applicant with less than 51 percent ownership sends the company to apply for a Certificate of Authorization instead. Section 40-59-240(A) limits any residential specialty contractor to three classifications; a person wanting more must be examined and licensed as a residential builder.

PSI administers the residential exam through the commission's own portal. The applicant must pass both the Business Management and Law portion and the Residential Electrical technical portion. Once approved, examination eligibility is valid for one year and allows three attempts inside a twelve month period. Failing three times means waiting twelve months from the last failure. Four waiver routes drop the technical portion but not the experience requirement or the Business Management and Law portion: holding a South Carolina Mechanical Contractor license with the Electrical (EL) classification, active and in good standing for a year or more and obtained by examination; holding a license obtained by examination and held for a year or more in Mississippi or North Carolina; passing the NASCLA Accredited Electrical exam within the past three years; or holding a Master Residential Electrician or Master Electrician Certification issued by examination between December 1990 and December 2025 by MASC, or after January 1, 2026 by Carolinas AGC. Grandfathered out of state licensees do not qualify. The published Residential Electrician fees are a $135 application fee, a $220 license fee, a $220 renewal fee, a $50 renewal late fee and a $480 reinstatement fee. Bonding is triggered by job size rather than by licensure. Regulation 106-2 requires a surety bond of not less than ten thousand dollars when the cost of an undertaking exceeds five thousand dollars, and Sections 40-59-220(D) and 40-59-240(D) carry the same trigger. The commission's application package specifies a $10,000 bond with the power of attorney attached and the individual's name, not a company name, as principal, on file before performing or offering to perform work above that amount. Handwritten and DocuSign bonds are refused.

Two primary sources do not line up on the residential renewal period, and both are reported here. Section 40-59-230(A) says the commission shall annually renew all licenses on submission of the completed renewal application, proof of financial responsibility or bond, and payment of all applicable fees, and Section 40-59-220(A) says licensees and registrants must pay an annual fee. The commission's own renewal page instead runs two year cycles: it describes a 2026-2028 renewal period for Residential Builder, Home Inspector and Certificate of Authorization licenses, with a deadline of June 30, 2026 to renew without penalty, late renewal open until June 30, 2027 at a $50 late fee on top of the $220 renewal fee, and reinstatement at $480 after that. A license in inactive status for more than three years requires a new application and re-examination under 40-59-230(A). On continuing education, Section 40-59-230(B) says the commission may require by regulation that a licensee satisfactorily complete continuing education through a commission approved program. Regulation Chapter 106 as published by the Legislative Council contains classification, licensing, fee, home inspector qualification and emergency license rules and sets out no continuing education hours for residential specialty contractors. On the commercial side, neither the Contractor's Licensing Board renewal page nor its published board FAQ states a continuing education requirement for general or mechanical contractors. What the board does require at every renewal is a current financial statement or surety bond.

Section 40-11-290 lets the board 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, where the board has authorized an exam waiver agreement with that state. It also allows an applicant to skip the technical examination by verifying passage of an essentially equivalent examination elsewhere even without a reciprocal agreement. The applicant may still be required to pass the South Carolina Commercial Contractors Business, Law and Project Management examination. The board publishes the current list as a Technical Exam Waiver Agreements sheet, revised May 2026. For the Electrical classification it names Alabama Electrical, Georgia Unrestricted Electrical with a note that Georgia no longer accepts South Carolina waiver applicants, Mississippi Electrical, North Carolina Limited, Intermediate and Unlimited Electrical, Ohio Electrical, Pennsylvania (Reading) Mechanical/Electrical, Tennessee CE, and Utah Master Electrician for exams passed before May 2017. It also accepts Carolinas AGC and MASC Master Electrical certifications where the exam was passed after January 1, 1990, and the NASCLA Electrical Examination Program from all states administering the NASCLA accredited exam. Two disqualifiers are stated on the board's licensure page. If the existing license in one of those states was obtained by waiver or by being grandfathered, the applicant is not eligible. If the state is listed but the trade or classification is not, the applicant is not eligible. The residential side is narrower: the Residential Builders Commission names only Mississippi and North Carolina as eligible states for its exam waiver.

The penalties run on two tracks. Criminally, Section 40-11-200(A) makes practicing or offering to practice in violation of the chapter, or knowingly submitting false information to obtain a license, a misdemeanor punishable on conviction by imprisonment of not more than one year or a fine of not more than five thousand dollars. Section 40-11-200(B) also makes it a violation for an awarding authority, owner, contractor, or agent to consider a bid, sign a contract, or allow a contractor to begin work before the required license is obtained. Administratively, Section 40-11-100 lets the department issue citations and cease and desist orders against anyone including unlicensed contractors, with penalties capped at five hundred dollars for a first violation of a provision, one thousand dollars for a second violation of the same or substantially similar provision within five years, and no more than two thousand five hundred dollars in administrative penalties per entity per day. Section 40-11-110(C) lets the board impose a civil penalty of up to five thousand dollars for each violation. The commercial consequence is in Section 40-11-370(C): an entity without a valid license may not bring an action at law or in equity to enforce a contract, and neither may an entity that contracted in a name other than the name on its license. Section 40-11-300(B) requires an unlicensed entity to withdraw from the project immediately and bars it from acting as a subcontractor there. On the residential side, Section 40-59-30(A) makes unlicensed residential specialty contracting a misdemeanor punishable by a fine of not less than five hundred dollars or more than ten thousand dollars or imprisonment for not less than thirty days, or both, and 40-59-30(B) bars the mechanics' lien and the contract action.
South Carolina has a vehicle and invoice display mandate, and electrical is not inside it. Section 40-11-270(B) requires each person holding a license in the mechanical contractor subclassification of air conditioning, heating, or packaged equipment to display the mechanical contractor license in a conspicuous manner at his principal place of business. Section 40-11-270(C) requires all commercial vehicles used by mechanical contractors licensed in those same three subclassifications exclusively in the daily operation of their business to have the mechanical contractor license number prominently displayed, and requires the number on each invoice and proposal form. Both subsections were added by Act No. 193 of 2016 and both name only air conditioning, heating, or packaged equipment. An Electrical subclassification licensee is not named there. What does bind an electrical contractor is the naming rule. Section 40-11-370(A) makes it unlawful to use the term licensed contractor or to perform or offer to perform general or mechanical construction without a license. Section 40-11-370(B) makes it unlawful to engage in construction under a name other than the exact name which appears on the license, and defines engaging in construction to include marketing, advertising, using site signs, and submitting contracts. The one carve-out is vehicles: advertising on vehicles may use an abbreviated version of the license name so long as the advertising is not misleading. Section 40-11-110(A)(11) makes false, misleading, or deceptive advertising whereby a member of the public may be misled and injured a ground for discipline, and 40-11-110(A)(21) covers contracting or offering to contract outside your group or classification. On the residential side, Section 40-59-20 prohibits a residential specialty contractor from undertaking work outside the scope of his license, including by hiring or subcontracting others to do it.
Code adoption is not done by either contractor board. The South Carolina Building Codes Council adopts the mandatory codes referenced in Section 6-9-50, and every municipality and county must enforce them. The Council adopted the current set on October 6, 2021 and set the implementation date for local jurisdictions as January 1, 2023. The electrical code in that set is the 2020 National Electrical Code (NFPA 70) with South Carolina modifications. The rest of the package is the 2021 editions of the building, residential, fire, plumbing, mechanical and fuel gas codes with South Carolina modifications, plus the 2009 International Energy Conservation Code. The Council states that only the modifications approved and listed on its website are valid for use in the state, and that building code modifications not approved by the Council cannot be adopted, employed, or enforced by municipalities and counties. Appendices to the mandatory codes may not be used by a local jurisdiction unless specifically adopted as a local modification by the Council. The next cycle is under way. A Notice of Intention to Modify and Adopt Building Codes was published in the State Register on January 24, 2025 and lists the 2024 editions of the building, residential, fire, plumbing, mechanical and fuel gas codes together with the 2023 Edition of the National Electrical Code. The comment window for modification requests ran from February 3, 2025 to August 4, 2025, the Council acted on modifications at its August 26, 2025 meeting, and the 2024 code modifications were published in the State Register on May 22, 2026.

A state license does not finish the paperwork. The Contractor's Licensing Board tells licensees plainly that cities and counties where they plan to work may require additional licensing or permitting, that each has its own rules, regulations and fees, and that the way to check is to call the business license or building permit department for that city or county. Two statutes back that up from the state side. Section 40-11-350 requires a building official or other permit issuing authority to refuse a permit for work that would classify the applicant as a contractor unless the applicant furnishes evidence of licensure or exemption, and requires that official to report suspected violators to the department. Section 40-11-420(A) requires the building permit to be obtained by the sole prime contractor in the name appearing on that entity's contractor's license. On the residential side, Section 40-59-240(C) gives an electrician a useful shield: a county or municipality may require a residential specialty contractor to be examined and licensed to its own standards, but if the contractor has passed an examination in his area of contracting approved by the commission, no additional examination may be required by that county or municipality. In the City of Charleston, all businesses operating or generating income in the city must pay an annual business license fee, with the fee based on gross income and the rate class assigned to the business NAICS code; applications and permits run through the city's Customer Self-Service portal and the Permit Center at 2 George Street. North Charleston's business license ordinance requires every person engaged or intending to engage in any calling, business, occupation or profession within the corporate limits to pay an annual license fee and obtain a license, and requires a new business to hold one before operating.

LLR runs one public verification system for every board it administers, and it is the fastest thing to put in front of a homeowner who asks whether you are licensed. The general entry point is the LLR Licensee Lookup. The Contractor's Licensing Board publishes a contractor specific lookup that returns general and mechanical contractor licenses, and the Residential Builders Commission publishes its own lookup covering residential builders, residential specialty contractors, home inspectors and certificates of authorization. Because South Carolina splits the trade across two boards, a contractor working both sides of the $10,000 line appears in two different result sets, and a customer searching only one lookup can come away thinking a genuinely licensed electrician is unlicensed. That is worth naming in an estimate. Both boards also publish final orders and disciplinary records. The Contractor's Licensing Board posts Board Orders, and the Residential Builders Commission posts orders through the LLR public orders system. Complaints against either credential are filed online or by mail to the LLR Office of Investigations and Enforcement at PO Box 11329, Columbia, SC 29211. Section 40-11-110(K) states that a final order of the board finding a violation becomes public knowledge, except for an order dismissing the complaint, issuing a letter of caution, or imposing a private reprimand. For a contractor, the practical reading is that the lookup entry, the license name and the order history are the public record a customer will find, so keeping the licensed entity name identical to the trading name is not only a Section 40-11-370(B) obligation, it is what makes the search return you.

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.
Yes, through two boards. The Contractor's Licensing Board licenses the business as a mechanical contractor in the Electrical subclassification for work above $10,000 under Section 40-11-30. The Residential Builders Commission licenses the individual as a Residential Electrician for residential work above $500 under Section 40-59-20(7).
Section 40-11-30 sets it at a total cost of construction greater than ten thousand dollars for mechanical contracting, which is where electrical sits. Act No. 69 of 2023 raised that from five thousand dollars.
Five hundred dollars. Section 40-59-20(7) defines a residential specialty contractor by undertakings that exceed five hundred dollars and are not regulated by Chapter 11. Act No. 186 of 2022 raised it from two hundred dollars.
Section 40-59-270 says a mechanical contractor is exempt from the residential specialty contractor rules when engaged in contracting in the classification in which he is licensed to perform mechanical contracting.
The Contractor's Licensing Board requires at least two years of work experience performed within the past five years for the classification sought, primarily commercial. The Residential Builders Commission requires a minimum of one year of residential electrical experience performed within the past five years.
On the commercial side, the South Carolina Business Management and Law for Commercial Contractors exam plus the Electrical technical exam. On the residential side, both the Business Management and Law portion and the Residential Electrical technical portion. PSI administers both sets.
Yes on the commercial side. Section 40-11-260 allows a surety bond in the same amount as the required net worth or working capital for your license group. The published mechanical amounts run from $7,000 for Group 1 to $300,000 for Group 5.
The commission publishes a $135 application fee, a $220 license fee, a $220 renewal fee, a $50 renewal late fee and a $480 reinstatement fee.
Section 40-59-230(B) lets the Residential Builders Commission require it by regulation, but Regulation Chapter 106 as published sets no hours. The Contractor's Licensing Board renewal page and board FAQ state no continuing education requirement for general or mechanical contractors.
Not as an electrical contractor. Section 40-11-270(B) and (C) apply the place of business display and the commercial vehicle, invoice and proposal number requirements only to the air conditioning, heating, and packaged equipment subclassifications.
Section 40-11-370(B) makes it unlawful to engage in construction under a name other than the exact name on the license, and counts marketing, advertising, site signs and contracts as engaging in construction. Vehicle advertising is the exception and may use an abbreviated version of the license name if it is not misleading.
The 2020 National Electrical Code with South Carolina modifications, adopted by the Building Codes Council on October 6, 2021 with a local implementation date of January 1, 2023. The Council has published a notice of intention to adopt the 2023 edition with the 2024 I-codes.
