What Types of Plumbing Licenses Exist in South Carolina?

South Carolina offers three primary plumbing license classifications, each with distinct scopes of work and experience requirements:

💡 Note: South Carolina does not issue apprentice licenses—instead, you register as an apprentice with the South Carolina Department of Labor, Licensing and Regulation (LLR) while working under a licensed plumber.

Step-by-Step: How to Get a Plumbing License in South Carolina

Step 1: Meet Basic Eligibility Requirements

Before applying, ensure you meet these non-negotiable criteria:

• Be at least 18 years old
• Have a high school diploma or GED
• Be legally authorized to work in the U.S.
• Have no disqualifying criminal convictions (LLR reviews on a case-by-case basis)

Step 2: Gain Required Work Experience

Experience must be documented and verified by a licensed South Carolina plumber or contractor.

• For Journeyman: Complete 4,000 hours (≈2 years full-time) of hands-on plumbing work under supervision.
• For Master: Complete 8,000 hours total, with at least 4,000 hours after obtaining your journeyman license.

📌 Pro Tip: Keep a detailed log of your hours, tasks performed, and supervisor contact info. The LLR may audit your records.

Step 3: Complete Required Education (If Applicable)

While South Carolina doesn’t mandate formal classroom education, most successful candidates take prep courses. Approved providers like Plumbing-Heating-Cooling Contractors Association (PHCC) or UA Local 448 offer SC-specific exam prep covering:

• State plumbing code (based on the IPC – International Plumbing Code)
• Blueprint reading
• Backflow prevention
• Gas piping regulations

🔗 For reference, the IPC is maintained by the International Code Council and aligns with standards recognized globally—learn more on Wikipedia .

Step 4: Submit Your Application to the LLR

Apply online via the South Carolina LLR portal (llr.sc.gov ):

• Journeyman Application Fee: $60
• Master Application Fee: $100
• Processing time: 7–10 business days

Step 5: Pass the South Carolina Plumbing Exam

✅ Pass Rate Insight: According to LLR data, first-time pass rates hover around 65%—but candidates who take prep courses see pass rates jump to 85%+.

Step 6: Receive Your License & Maintain It

Once you pass, your license is issued within 5 business days. Licenses expire every two years on June 30.

• Renewal Fee: $60 (journeyman), $100 (master)
• Continuing Education: Not currently required in SC—but highly recommended to stay current with code updates.

Common Mistakes to Avoid

Many applicants stumble on avoidable errors:

• Underestimating code knowledge: The exam tests application, not just memorization.
• Incomplete experience documentation: Vague logs get rejected.
• Missing deadlines: Applications submitted after exam registration may delay your test date.
• Ignoring local amendments: Some counties (e.g., Charleston) have additional plumbing rules.

Journeyman vs. Master Plumber: Which Should You Pursue?

If you’re just starting out, begin with the journeyman license. It’s your gateway to credibility and higher pay—without the pressure of full liability.

FAQ: How to Get a Plumbing License in South Carolina

Q: Can I get a plumbing license in SC with an out-of-state license?

A: South Carolina has limited reciprocity. You may qualify for exam waiver if licensed in a state with substantially equivalent requirements (e.g., Georgia, North Carolina). Submit a Reciprocity Application with proof of active license and exam scores.

Q: How much does it cost total to get licensed?

A: Expect to spend $300–$600, including:

• Application fees ($60–$100)
• Exam fee ($85)
• Prep course ($150–$400)
• Study materials ($50)

Q: Do I need a contractor’s license to do plumbing work?

A: Only if you own a business or advertise as a contractor. Individual plumbers need a journeyman or master license—but not a separate contractor’s license unless managing projects or employees.

Q: How long does the entire process take?

A: From start to license: 2–6 months, depending on your experience level and exam scheduling. If you already have the hours, you could be licensed in under 8 weeks.

Q: Can felons get a plumbing license in SC?

A: Possibly. The LLR evaluates criminal history based on nature, severity, and rehabilitation. Minor, non-violent offenses (especially older ones) may not disqualify you. Disclose everything honestly—omission = automatic denial.

Q: Is the SC plumbing exam open-book?

A: No. It’s a closed-book, proctored exam. You’ll be provided with a copy of the South Carolina Plumbing Code during the test, but you must know how to navigate it quickly.
