Thinking about becoming a licensed journeyman plumber in South Carolina? You’re not alone. With the construction industry growing and skilled trades in high demand, many professionals are turning to plumbing as a stable, well-paying career. But if you’re wondering, “How do I get my journeyman plumbing license in South Carolina?”—you’ve come to the right place. This guide breaks down every requirement, step, and insider tip so you can navigate the process with confidence.
What Is a Journeyman Plumber License in South Carolina?
In South Carolina, a journeyman plumber license allows you to perform plumbing work independently under the supervision of a licensed master plumber. Unlike an apprentice, a journeyman has completed formal training and passed a state exam, proving technical competence in residential and commercial plumbing systems.
According to the South Carolina Department of Labor, Licensing and Regulation (LLR), all plumbing work must be performed by or under the direct supervision of a licensed plumber—making this license essential for career advancement.
💡 Did You Know?
The U.S. Bureau of Labor Statistics projects a 5% growth in plumber jobs nationwide from 2022–2032—faster than average. In South Carolina, demand is especially strong in fast-growing areas like Charleston, Greenville, and Myrtle Beach.
Who Regulates Plumbing Licenses in South Carolina?
The South Carolina Board of Plumbing Examiners, under the LLR, oversees all plumbing licenses. They set education, experience, and examination standards—and enforce compliance with the state plumbing code.
Unlike some states, South Carolina does not offer reciprocity with other states’ plumbing licenses. Even if you’re licensed elsewhere, you’ll need to meet SC-specific requirements.

Journeyman vs. Master Plumber License: What’s the Difference?
| Feature | Journeyman License | Master Plumber License |
|---|---|---|
| Supervision Required? | Yes (by a master) | No |
| Can Pull Permits? | No | Yes |
| Experience Needed | 4 years | 2 additional years (total 6) |
| Exam Difficulty | Moderate | Advanced (includes business/law) |
| Average Salary (SC) | $52,000–$65,000 | $70,000–$90,000+ |
Many journeymen use this license as a stepping stone to master status—especially if they plan to start their own plumbing business.
Common Mistakes to Avoid
- ❌ Underestimating the code knowledge needed – The exam is heavily code-based.
- ❌ Submitting incomplete experience affidavits – Each employer must verify dates, hours, and duties.
- ❌ Waiting until the last minute to apply – Processing can take 2–3 weeks.
- ❌ Ignoring continuing education – Letting your license lapse means restarting the entire process.
Why Getting Licensed Matters
Beyond legal compliance, a journeyman license:
- Boosts earning potential by 20–30%
- Builds client trust (homeowners prefer licensed pros)
- Opens doors to union jobs, commercial projects, and government contracts
- Protects you legally in case of disputes or inspections
As noted by the National Association of Plumbing-Heating-Cooling Contractors (PHCC), “Licensing isn’t just a piece of paper—it’s proof you meet industry standards for safety and quality.”
