South Carolina splits electrical licensing between the Residential Builders Commission and the Contractor's Licensing Board, with narrow reciprocity, exam waivers, fees, and the 2026 MASC to CAGC certification change explained.
South Carolina licenses electricians through two separate boards, not two tiers of one license: the Residential Builders Commission for residential work and the Contractor's Licensing Board for commercial work. Which board you deal with depends on the dollar value and type of work you intend to do, not your experience level or job title.
This guide is checked against the South Carolina Department of Labor, Licensing and Regulation (LLR), including the Residential Electrician license application package most recently revised December 2025. Fees, thresholds, and exam rules are set by the boards and the testing vendor and change, verify before paying.

At a glance
- Residential electrical work over $500 needs an RBC Residential Electrician license; commercial work over $10,000 needs a CLB Mechanical Contractor license with the Electrical (EL) classification.
- Reciprocity is narrow: the RBC waives only the technical exam, and only for licensees from North Carolina or Mississippi with one year or more of experience by examination.
- As of January 1, 2026, Carolinas AGC (CAGC) administers the Master Electrician certification program MASC used to run.
- Residential fees run $135 application plus $220 license; commercial licensure is $350.
The Two-Board Split
Residential Builders Commission (RBC). Handles the Residential Electrician license. Residential electrical work exceeding $500 requires this license.
Contractor's Licensing Board (CLB). Handles commercial work. If you intend to perform commercial electrical work exceeding $10,000, you need a Mechanical Contractor license with the Electrical (EL) classification from the CLB.
These are not tiers of the same license. They are different boards, different applications, different exams, and different fee schedules. Some people end up holding both. Figure out which side of that line your work falls on before you spend a dollar.
Reciprocity: What Out of State Electricians Need to Know
"South Carolina electrical license reciprocity" is one of the more common searches that lands on this page, and the honest answer is that reciprocity here is narrower than most electricians expect, and it works differently depending on which board you are dealing with.
Residential reciprocity (RBC)
The Residential Builders Commission waives only the technical portion of its exam, and only for two states. A current license from North Carolina or Mississippi, obtained by examination and held for one year or longer, lets you skip the Residential Electrical technical exam. Grandfathered licenses from either state do not qualify, and you still have to pass the Business Management and Law exam and meet the one year experience requirement described below.
Commercial reciprocity (CLB)
The Contractor's Licensing Board runs a separate reciprocity structure for its Mechanical Contractor Electrical (EL) classification, built on a Technical Exam Waiver Agreement List the Board keeps on file. The version of that list we reviewed, carrying a 2019 revision date, covered electrical licensees from Alabama, Georgia, Mississippi, North Carolina, Ohio, Pennsylvania (Reading only), Tennessee, and Utah, with the specific accepted exam varying by state. That list can change, so confirm your state and exam are still on the current version before you rely on it, the Board can verify at Contact.CLB@llr.sc.gov. Whichever state you come from, every CLB applicant, waiver or not, still has to pass the South Carolina Business Management and Law for Commercial Contractors exam.
What reciprocity does not cover
Reciprocity waives a technical exam, not the license itself. You still apply to the relevant South Carolina board, still meet its paperwork and experience requirements, and still hold a South Carolina license separate from your home state license. If you are coming from North Carolina specifically, our North Carolina electrician license guide covers that side of the comparison, and our NASCLA exam guide covers what the NASCLA credential unlocks if your state is not on either list.
The 2026 Change: MASC Is Out, CAGC Is In
If you have held or are pursuing a South Carolina trade certification, this matters.
Historically the Municipal Association of South Carolina (MASC) administered the SC Mechanical Trades Certification Program, the Master Electrician certification that a lot of South Carolina electricians carry. As of January 1, 2026, Carolinas AGC (CAGC) is the SC Mechanical Trades Certification Program provider, now called the CAGC SC Trades Certification Program.
What that means in practice:
- A Master Electrician Certification issued by examination between December 1990 and December 2025 by MASC is still recognized.
- A certification issued after January 1, 2026 comes from CAGC.
- If you hold a MASC certification and need to use it in an application, you now contact CAGC to obtain a certification verification letter, not MASC.
- The exam itself, its standards, and its testing process have not changed. PROV, not PSI, remains the test administrator for the trade certification exam, handling scheduling, delivery, and scoring.
That last point catches people. Your old MASC certification is fine, the office you request verification from has changed. For the certification exam itself, CAGC can be reached at cagctrades@cagcfoundation.org or 803-933-1209.
Path A: Residential Electrician (RBC)
This is the license for residential electrical work over $500.
Experience
You must show a minimum of one year of residential electrical experience performed within the past five years. That five year recency window is strict, a decade old year of experience does not count.
Documentation is specific:
- A Residential Electrician Experience Affidavit completed by each supervisor or employer listed in your work experience section, notarized
- Copies of W-2s and/or 1099s from each of those employers
- The person completing the affidavit must have been appropriately licensed during the dates of supervision, a licensed residential electrician, residential builder, or mechanical contractor with the electrical classification, and must have direct personal knowledge of your work
If the information on your application does not match the affidavits, the application comes back for corrections. Fill them out together, not separately.
The affidavit asks the supervisor to identify what you actually did: service panel installation and upgrades, general residential wiring, new construction wiring, remodel and renovation wiring, service call troubleshooting, estimating and plan review, with approximate project counts, plus specialty work like pool and spa wiring, solar PV connections, EV charger installation, and generator and transfer switch work. It closes with a direct question to your supervisor: does this applicant have the knowledge and experience to independently perform full-scope electrical work on an entire home? Plan for the person signing to actually be able to answer yes.
Examination
PSI Examination Services administers the Commission's exams. You must pass both portions:
- Business Management and Law
- Residential Electrical (technical)
Work experience must be verified and approved before you are made eligible for the exam. Once approved, your eligibility is valid for one year, and you get three attempts within a twelve month period. Fail to pass both portions in that window and you reapply from the start. Fail three times and you wait twelve months from the last failure before you can test again.
Exam fees are paid directly to PSI and are set by the vendor.
Exam Waiver Routes
The technical portion can be waived, the experience requirement and the Business Management and Law exam still apply, if you:
- Are a currently licensed SC Mechanical Contractor with the Electrical (EL) classification, in good standing, active for one year or longer, obtained by examination
- Hold a current license obtained by examination for one year or longer in North Carolina or Mississippi (see Reciprocity above). Grandfathered licensees do not qualify
- Passed the NASCLA Accredited Electrical exam within the past three years, with a copy of your transcript included
- Hold a current Master Residential Electrician or Master Electrician Certification issued by examination between December 1990 and December 2025 by MASC, or after January 1, 2026 by CAGC
The Requirements Nobody Warns You About
Three South Carolina specific items regularly derail applications.
Credit report. Under S.C. Code Section 40-59-250, you must submit a copy of your credit report dated no more than 30 days before your application date (TransUnion, Equifax, or Experian). It is reviewed for liens and outstanding judgments. Pull it late in your prep, not early, a stale report gets rejected on a technicality.
License bond. If you will do work exceeding $5,000 total cost of construction (labor and materials) on a project, a $10,000 surety bond must be on file with the Commission, with power of attorney attached and the individual's name as principal. It cannot be in a company or business name. Handwritten bonds and bonds signed via DocuSign are not accepted. You do not have to submit it with the application, but it must be on file before performing or offering to perform work above that threshold. Bond premiums are set by the surety, not the state, and depend on your credit and history.
51% ownership rule. You must own at least 51% of a company to list it on your license. If you do not, the company must apply for a Certificate of Authorization. This is a hard structural rule and it shapes how South Carolina electrical businesses get organized.
You will also submit a notarized Verification of Lawful Presence affidavit, a government issued ID, and a copy of your Social Security card. The application's personal history questions also ask about prior license discipline, pending investigations, and any judgments or liens against you or businesses you have been associated with in the past five years. A yes answer needs a written explanation, and a criminal conviction needs a background check from SLED or the state where it occurred, dated within 30 days of your application.
Residential Electrician Fees
Board set, subject to change, verify with LLR:
| Fee Type | Amount |
|---|---|
| Application Fee | $135 |
| License Fee | $220 |
| Renewal Fee | $220 |
| Renewal Late Fee | $50 |
| Reinstatement Fee | $480 |
Your application is good for one year from receipt. If everything is not in within that year, you start over, including the fee.
Lapsed licenses: lapsed less than three years, you may apply for reinstatement. Lapsed more than three years, you apply as a new applicant, which requires reexamination.
Path B: Commercial Electrical (CLB) and the Qualifying Party System
For commercial electrical work over $10,000, you are dealing with the Contractor's Licensing Board, and South Carolina's structure here is unusually explicit about the role of the licensed individual.
The Primary Qualifying Party
South Carolina requires every licensed entity to designate a Primary Qualifying Party (PQP) for each classification it holds. The Board defines the PQP as the principal individual responsible for directing or reviewing the work performed by the applicant in that classification. Additional Qualifying Parties (QPs) are individuals who have met the same exam requirements but are not the designated primary.
The sequencing is strict: PQPs must complete the exam requirements for certification before the entity submits its license application. You cannot apply first and sort out the qualifier later.
Requirements for PQP or QP certification:
- Qualify by technical examination, exam waiver/reciprocity, or CAGC/MASC certification
- Pass the S.C. Business Management and Law for Commercial Contractors exam, required of all applicants regardless of route
- Submit at least two years of work experience performed within the past five years for the requested classification (waiver and reciprocity applicants excepted). Unless specifically listed otherwise, experience should be primarily commercial
Electrical is a Mechanical Contractor classification with a technical exam, alongside Air Conditioning, Heating, Plumbing, Refrigeration, Process Piping, Packaged Equipment, and Lightning Protection. Exams are through PSI. The Board also accepts the NASCLA Accredited Trade Examination for Electrical Contractors for those licensing across multiple states.
Key forms: Doc. 165 (initial license application), Doc. 167 (work experience affidavit), Doc. 168 (PQP/QP initial application), Doc. 181 (PQP/QP revision, including transferring an existing certification to a new license), and Doc. 173 (to act as a Dual Qualifying Party for two licensed entities).
Financial Requirements
Licensure fee is $350 (Board set, verify). Mechanical Contractor licenses expire October 31 in odd numbered years; General Contractor licenses expire October 31 in even numbered years.
Your bid and job limits are set by group, and you qualify by financial statement or surety bond:
| Group | Bid/Job Limit | Net Worth or Working Capital | Surety Bond |
|---|---|---|---|
| 1 | $35,000 | $7,000 NW or $3,500 WC | $7,000 |
| 2 | $100,000 | $15,000 NW or $10,000 WC | $15,000 |
| 3 | $200,000 | $30,000 NW or $20,000 WC | $30,000 |
| 4 | $400,000 | $60,000 NW or $40,000 WC | $60,000 |
| 5 | Unlimited | $300,000 NW or $200,000 WC | $300,000 |
Notes on the table:
- NW is net worth (total assets minus total liabilities); WC is working capital (current assets minus current liabilities). You must meet either figure, not both.
- Groups 1 and 2 may use an owner prepared financial statement with an affidavit of accuracy (Doc. #172); Groups 3 and 4 need a CPA compiled statement for initial licensure; Group 5 needs an audited balance sheet.
- Surety bonds must be continuous, name the State of South Carolina as obligee, and carry a visible surety seal with power of attorney attached. DocuSign signatures are not accepted, and bonds payable to the Residential Builders Commission are not accepted by the CLB.
Local Licensing
Once licensed by the Board, cities and counties where you work may require additional local business licenses and permits, each with its own rules and fees. Check the municipality or county before you bid there.
What This Means for Electrical Business Owners
South Carolina named the concept for you. The Board's own term is Primary Qualifying Party, "the principal individual responsible for directing or reviewing work performed by the applicant." That is a qualifying agent, described in the state's own regulatory language.
The structural facts follow from that:
- No entity holds a commercial electrical classification without a certified PQP.
- The PQP must pass the exams before the entity applies.
- On the residential side, the 51% ownership rule means an unlicensed owner cannot simply attach someone else's license to their company without the Certificate of Authorization route.
So a South Carolina electrical company either has a qualified individual inside it, or it does not operate. That is the whole design.
This is also why the arrangement has to be genuine employment. South Carolina defines the PQP as the person responsible for directing or reviewing the work, a responsibility you cannot discharge as a distant name on a form collecting a monthly fee. A qualifying agent QUALIFIES the company, as an owner or full time W-2 employee who actually supervises the work, not a name attached to a license on paper only. The Licensing Company places qualifying agents exclusively as full time W-2 employees, never as independent contractors and never on a percentage or per project basis.
Our guides on what a qualifying agent is and the electrical contractor qualifying agent role go deeper on how this works. If your company needs one placed, our contractor qualifier services handle the search, vetting, and employment; see how we place qualifying agents for the details.
Frequently Asked Questions
Do I need a license for residential electrical work in South Carolina? Yes, for residential electrical work exceeding $500. Commercial electrical work exceeding $10,000 falls under the Contractor's Licensing Board instead.
Is there a statewide journeyman electrician license in South Carolina? Not in the structure most states use. South Carolina runs a Residential Electrician license through the Residential Builders Commission and an Electrical classification under Mechanical Contractor licensing through the Contractor's Licensing Board. Trade certifications (Master Electrician) come through the SC Mechanical Trades Certification Program, now administered by CAGC as of January 1, 2026.
Does South Carolina have electrician license reciprocity with other states? Only in a narrow sense, and it differs by board. The RBC waives its technical exam for North Carolina or Mississippi licensees with one year or more by examination; the CLB waives its technical exam for electrical licensees from a short list of other states, currently built around a Board maintained Technical Exam Waiver Agreement List. Either way, you still apply fresh, still meet the experience and paperwork rules, and still pass South Carolina's Business Management and Law exam.
How much experience do I need? Residential Electrician: one year of residential electrical experience within the past five years, documented by notarized affidavits plus W-2s or 1099s. CLB qualifying party: two years of work experience within the past five years, primarily commercial.
What happens if I fail the residential exam? You get three attempts within a twelve month eligibility period. Fail three times and you wait twelve months from the last failure before testing again.
Do I really need a credit report? Yes, for the Residential Electrician application, dated no more than 30 days before your application date, reviewed for liens and outstanding judgments, under S.C. Code Section 40-59-250.
How do I apply for a Master Electrician certification? Through the CAGC SC Trades Certification Program if you are certifying after January 1, 2026, or if you need a verification letter for a MASC certification issued before then. Reach CAGC at cagctrades@cagcfoundation.org or 803-933-1209.
How much does it cost to get a South Carolina electrician license? Residential: $135 application plus $220 license, then $220 per renewal, plus PSI exam fees and a $10,000 surety bond (premium set by the surety) if you exceed the $5,000 project threshold. Commercial: $350 licensure fee plus PSI exams and a financial statement or surety bond sized to your group limit. All board fees are subject to change; what qualifying a company actually costs depends on how many classifications and states are involved, so we scope that on a call rather than publish one number.
My company's qualifying party is leaving. What now? The entity's authority in that classification depends on having a certified PQP. Doc. 181 handles transferring an existing certification; Doc. 168 covers a new one. If you need a qualified person, we place qualifying agents as W-2 employees.
The Rest of South Carolina Mechanical Licensing (2026)
Electrical is one of eight mechanical subclassifications under the Contractor's Licensing Board, and the same two agency structure, the same $500 residential and $10,000 commercial thresholds, and the same qualifying party requirement apply across all of them. If you run a mixed trade shop, or you are weighing which classification to pursue first, the sister guides cover the other two big mechanical trades in the same detail:
- South Carolina plumbing license, the Residential Plumber License (RBP) and the Mechanical Contractor Plumbing (PB) classification, including the conditional $10,000 individual name bond, the credit report requirement under section 40-59-250, and the three attempts in twelve months exam rule.
- South Carolina HVAC license, the Residential HVAC Installer and Repairer License (RBH) and the four commercial subclassifications, including the 25 ton / 500,000 BTU cap on Packaged Equipment, the AC versus Heating boundary, and the license number display rules that apply to every service vehicle and every proposal.
One cross trade note worth knowing if you hold the Electrical classification: the Electrical (EL) subclassification at section 40-11-410(5)(d) permits installing window or through the wall air conditioning units up to three horsepower or three tons where no piping is necessary. Above that, or wherever refrigerant piping is involved, the work belongs to a mechanical HVAC subclassification.
And the requirement that decides whether the company can be licensed at all, the Primary Qualifying Party in a responsible management position, the one licensee rule, the narrow two entity exception, and the 15 day/90 day disassociation clock, is set out in full in South Carolina's primary qualifying party rules.

Next Steps
Decide which board you belong to first, the $500 residential threshold and the $10,000 commercial threshold are the deciding lines, and everything else follows from that choice.
If you are pursuing the residential license: line up your notarized experience affidavits and matching W-2s early, pull your credit report inside the 30 day window, and check whether a waiver route (NC or MS licensure, NASCLA, or a MASC/CAGC master certification) saves you the technical exam.
If you are a business owner who needs a certified qualifying party and does not have one, that is a hiring problem with a licensing deadline attached, and in South Carolina, the exams have to be passed before the entity can even apply. We place qualifying agents as full time W-2 employees in South Carolina and nationwide: call 615-219-2110, see how we place qualifying agents, or browse state licensing guides for a multi state view.
