Dreaming of a stable, hands-on career with strong demand and good pay? You’re not alone. Many Americans are turning to skilled trades like plumbing—and in Kentucky, the path to becoming a licensed plumber is clear, structured, and full of opportunity. Whether you’re a high school grad, a career switcher, or someone looking for job security, this guide breaks down how to become a licensed plumber in Kentucky—step by step, with real data and expert insights.
Why Get a Plumbing License in Kentucky?
Before diving into the steps, it’s worth understanding why licensure matters. In Kentucky, it’s illegal to perform plumbing work for compensation without the proper license. More importantly, licensed plumbers earn significantly more: the average annual salary in KY is $52,390, with top earners making over $70,000 (U.S. Bureau of Labor Statistics, 2024). Plus, plumbing jobs are recession-resistant—people always need clean water and working drains!
Step 1: Meet the Basic Eligibility Requirements
To even begin the licensing process in Kentucky, you must:
Be at least 18 years old
Have a high school diploma or GED
Be a U.S. citizen or legal resident
Pass a background check (no felony convictions related to fraud or violence)
No prior plumbing experience is needed to start—just the willingness to learn.
Step 2: Complete a State-Approved Plumbing Apprenticeship
Kentucky requires 4 years (576 hours of classroom instruction + 7,000+ hours of on-the-job training) under a licensed master plumber. You can fulfill this through:
Union programs (e.g., UA Local 277 in Louisville)
Non-union apprenticeships (often sponsored by plumbing contractors)
Trade schools like Ashland Community & Technical College or Somerset Community College, which partner with local employers
💡 Pro Tip: Many apprenticeships are paid! You’ll start earning while you learn—typically $15–$20/hour in Year 1, increasing with skill.
Apprenticeships cover:
Pipefitting & fixture installation
Kentucky Plumbing Code (based on the International Plumbing Code)
After completing your apprenticeship, you’re eligible to take the Kentucky Journeyman Plumber Exam. Here’s what to do:
Submit an application to the Kentucky Master and Journeyman Plumbers Licensing Board (fee: $75)
Provide proof of 7,000+ hours of hands-on experience
Schedule your exam through PSI Exams (the state’s testing partner)
Exam Details:
Format: 80 multiple-choice questions
Time limit: 4 hours
Passing score: 70%
Topics: Drainage systems, water supply, venting, Kentucky-specific code amendments
📚 Study Resource: The Kentucky Board provides an official exam content outline and recommends using the 2021 Kentucky Plumbing Code and IPC 2021 as primary references.
Once you pass, your Journeyman License arrives in 2–4 weeks. With it, you can work independently—but not run your own plumbing business.
Step 4: Gain Experience as a Journeyman (Optional: Move to Master License)
To become a Master Plumber—the highest license tier—you must:
Hold a Journeyman License for at least 2 years
Complete 4,000 additional supervised work hours
Pass the Kentucky Master Plumber Exam ($100 fee)
Master plumbers can: ✅ Start their own plumbing company ✅ Pull permits ✅ Supervise apprentices and journeymen
📊 Did You Know? Kentucky has over 3,200 licensed plumbers, but demand is growing. The state projects a 12% increase in plumbing jobs by 2030—faster than the national average (KY Cabinet for Economic Development).
