Two State Tracks Cover Plumbing Work
A South Carolina plumbing license is not one card from one office. The state splits plumbing between two regulators, and which one applies depends on whether the job is residential and how large it is. Both sit under the Department of Labor, Licensing and Regulation, known as LLR.
We gathered these notes from public sources so you can ask sharper questions before hiring anyone, including us. Treat them as background reading rather than legal counsel. Nothing here is a claim that our company holds any particular license.
Contractors' Licensing Board
Licenses general and mechanical contractors under Title 40, Chapter 11. Plumbing sits inside mechanical construction, and state law requires a license once total construction cost passes $10,000.
Residential Builders Commission
Handles residential specialty trades under Chapter 59. Its own plumbing FAQ says each person doing the work needs a personal license, and companies cannot share one.
Owner-occupant exemption
Section 40-11-360 excuses owners working on a home they will live in, as long as it is not intended for sale or rent. Landlords and flippers cannot rely on it.
Journeyman and master credentials
Titles like journeyman plumber and master plumber exist, but the state does not issue them. They come from a municipal association program covered below.
What unlicensed work risks
Contracting without a required license is a misdemeanor under the mechanical chapter, and the residential chapter blocks unlicensed contractors from enforcing contracts or filing liens.
What a South Carolina Plumbing License Does and Does Not Prove
A license shows legal standing. It does not grade workmanship, so pair it with the habits below.
Run the SC plumbing license lookup before any deposit
LLR hosts a public Licensee Lookup. You can search by a contractor's name or license number and read the status, classification and any disciplinary history. The word you want is Active. Lapsed, inactive, suspended and cease-and-desist entries all mean the person should not be taking your job.
Check the classification too. A mechanical contractor with a plumbing classification and a residential plumbing licensee are different records. Ask which one the person holds and why it fits your project. A name that matches the truck but not the database is worth a pause.
What the residential track asks of a plumber
According to LLR's plumbing FAQ, an applicant needs one year of hands-on residential plumbing experience gained within the last five years under a licensed supervisor. The applicant must also pass a business and law exam plus a residential plumbing exam, both given through PSI Examination Services.
Someone who already holds a mechanical contractor license with a plumbing classification can skip the technical exam but still sits the residential business and law test. Reciprocity for North Carolina and Mississippi licenses waives only the technical portion.
Journeyman and master titles are not state licenses
The Municipal Association of South Carolina runs a Mechanical Trades Certification Program with levels for journeyman plumber, master plumber and master residential plumber. Its own brochure states the certification is not issued by the State of South Carolina and is an indication of skill level rather than legal permission to work.
The credential still carries weight. LLR waives certain examination requirements for holders of the association's master certifications, and some municipalities may ask for it before issuing permits. Treat it as a sign of training, then verify the state license separately. A friendly reputation is not a substitute for either.
A certificate on the wall and a license in the database are two different things. Ask for the second one.
Permits and inspections around Beaufort County
Plumbing work that changes pipes, fixtures or water heaters often needs a permit, and a permit brings an inspection. On Hilton Head Island the Town says the contractor you hire will usually submit the application for you, and inspection requests filed before 3 pm are booked for the following business day. Skipping that step can leave you with unapproved work.
Beaufort County lists plumbing among residential work that requires a permit, and its contractors must show a state license and a county business license. An owner-builder doing the work personally files an Unlicensed Residential Builder's Disclosure Statement with the county, a form the Town also points to. Bluffton, Beaufort and Hardeeville each run their own permit offices, so the right counter depends on the address. Bluffton's Growth Management office works from 20 Bridge Street, and Hardeeville's permit desk sits at 205 Main Street.
The code behind the inspection
Every South Carolina city and county must enforce the statewide mandatory codes. For plumbing that means the 2021 edition of the International Plumbing Code, with South Carolina modifications, adopted on October 6, 2021 and in effect since January 1, 2023. LLR's list shows the fuel gas code and the residential code moved to 2021 editions that day too.
The South Carolina plumbing code sets minimums for venting, drain slope, backflow protection and water heater installation. Local jurisdictions handle the administrative side, so fees and forms differ even though the technical rules are shared.
Warning Signs Before You Hire
None of these proves wrongdoing alone, but several together deserve a second look and a phone call to the permit office.
No license number offered
A legitimate contractor can give a number without hesitation and expects you to look it up.
Pressure to skip the permit
If a job needs one, avoiding it leaves you holding the risk at resale or insurance time.
A different name on the paperwork
The person who shows up should match the licensee, or be employed under one.
Cash-only, no written scope
Without a scope on paper, disputes have little to stand on.
Door knockers after a storm
Hurricane season brings unsolicited offers. Check the license with extra care before you sign.
Where Each Permit Office Sits
Local offices issue the permit and perform the inspection. The state license is the same everywhere in South Carolina.

Homeowner License FAQs
May I repair the plumbing in my own home?
State law excuses owners doing the work themselves on a residence they will occupy, if it is not meant for sale or rent. Local permit rules and the plumbing code still apply, and a hidden mistake becomes your own repair bill. Call the permit office before you start.
Can a handyman swap fixtures without a license?
The contractor chapter applies once total construction cost exceeds its dollar limit, but the residential chapter sets a much lower trigger for specialty trades. Ask LLR how your specific job is treated, and get the answer by email if you can so you have it on record.
Is the national exam the same as a state license?
No. An exam passed or a certification earned shows knowledge. The license is the legal authorization, and only the state grants it.
What if a contractor's status says lapsed?
Do not hire until it shows Active. A lapsed license may mean an unpaid renewal or a bigger problem, so ask the contractor directly and confirm with LLR before any money changes hands.
Who do I contact if work goes wrong?
LLR accepts complaints about licensees, and the permit office can reopen an inspection. Gather photos, the scope, receipts and text messages first so the timeline is clear.
Do these rules apply to commercial properties?
Yes. Commercial work also falls under the Contractors' Licensing Board, and permits are usually stricter for restaurants, rentals and shared buildings.
