Plumber License from Mississippi to South Carolina: Does It Transfer? (2026)
Does South Carolina accept a Mississippi plumbing license?
There is no Mississippi state license to carry to South Carolina: Mississippi issues no statewide journeyman plumber license. South Carolina does license this work, so ask the South Carolina Department of Labor, Licensing and Regulation — Residential Builders Commission whether it credits a local license or your documented experience; otherwise you qualify as a new applicant.

Verdict
No state license to transfer
The issue on this move is the starting point: Mississippi issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no Mississippi state license for South Carolina to verify or endorse. South Carolina does license plumbers, through the South Carolina Department of Labor, Licensing and Regulation — Residential Builders Commission, and it reviews out-of-state plumbers for endorsement, but that route starts from a state license. Ask the board, in writing, whether it credits a local Mississippi license, a contractor-level credential or your documented hours; otherwise plan to qualify as a new journeyman applicant. South Carolina waives only the technical (Residential Plumbing) portion of its exam for an applicant who holds a residential plumbing license obtained BY EXAMINATION, current and in good standing, in North Carolina or Mississippi — the only two states with a residential-plumbing Exam Waiver Agreement (grandfathered or waived-in licensees do not qualify); every applicant, including waiver applicants, must still pass the South Carolina Business Management and Law exam, and all others must pass both the Residential Plumbing technical exam and the Business/Law exam.
What's different between Mississippi and South Carolina
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into South Carolina. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
Mississippi to South Carolina (this page): No state license to transfer.
South Carolina to Mississippi (the reverse move): No state license to transfer.
Mississippi issues no statewide journeyman plumber license, so neither direction is a state-license transfer.
- Does coming from Mississippi matter?
Coming from Mississippi matters here: only 9 of 50 origins (the other 49 states and DC) get this result for a move into South Carolina.
The others get: licensure by endorsement (41).
- Fee and processing
Mississippi issues no statewide journeyman plumber license, so there is no Mississippi state license application fee or processing time to compare with South Carolina's.
- Exam rules on record
South Carolina and Mississippi carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- South Carolina (this move): South Carolina waives only the technical (Residential Plumbing) portion of its exam for an applicant who holds a residential plumbing license obtained BY EXAMINATION, current and in good standing, in North Carolina or Mississippi — the only two states with a residential-plumbing Exam Waiver Agreement (grandfathered or waived-in licensees do not qualify); every applicant, including waiver applicants, must still pass the South Carolina Business Management and Law exam, and all others must pass both the Residential Plumbing technical exam and the Business/Law exam
- Mississippi (the reverse move): Not applicable at the individual level: Mississippi issues no state journeyman or master plumber license to individuals, so there is no state journeyman exam to waive or transfer, and individual plumbers are licensed (where required) only by cities/municipalities. At the state level only plumbing CONTRACTORS/companies are licensed, by the Mississippi State Board of Contractors; that contractor reciprocity waives only the trade exam, and every contractor applicant must still pass the Mississippi Law and Business Management exam.
