Thinking about becoming a licensed plumber—but unsure how long it’ll take? You’re not alone. Many aspiring tradespeople ask, “How long does it take to get your plumbing license?” The answer isn’t one-size-fits-all, but with the right roadmap, you can turn your ambition into a rewarding, in-demand career—often faster than you think. Let’s break it down clearly, step by step.
What Exactly Is a Plumbing License?
Before diving into timelines, it’s important to understand what a plumbing license actually is. In the U.S., a plumbing license is a legal credential issued by a state (or sometimes local) licensing board that authorizes you to perform plumbing work independently. Without it, you can only work under the supervision of a licensed plumber—typically as an apprentice or journeyman.
Licensing ensures public safety, code compliance, and professional standards. According to the U.S. Bureau of Labor Statistics, employment of plumbers is projected to grow 5% from 2022 to 2032, faster than average—making now a smart time to enter the field.
How Long Does It Take to Get Your Plumbing License? (The Short Answer)
On average, it takes 2 to 5 years to earn a full plumbing license in the United States. However, this varies significantly by state, your prior experience, and how quickly you complete required training and exams.
Let’s unpack why.

Some states also require a background check or drug screening. This initial phase usually takes just a few weeks.
2. Complete a Plumbing Apprenticeship (2–5 Years)
This is the longest and most critical phase. Nearly every state mandates hands-on experience—typically 4,000 to 8,000 hours of supervised work—paired with classroom instruction.
Typical apprenticeship duration: 4–5 years
Hours per year: ~2,000 (full-time)
Classroom training: 144–200 hours per year (covering safety, blueprint reading, local codes)
Apprenticeships are often sponsored by unions (like UA Plumbers & Pipefitters) or trade schools. You earn while you learn—average apprentice wages start around $18–$25/hour, rising as you gain skills.
💡 Pro Tip: Some states (like Texas or Florida) allow credit for military plumbing experience or prior vocational training, potentially shortening your timeline.
3. Apply for Journeyman License (Varies by State)
After your apprenticeship, you’ll usually take a journeyman plumber exam. This license lets you work independently but not run your own business.
Exam prep time: 1–3 months
Processing time: 2–8 weeks
Pass rate: Varies, but averages 60–75% on first attempt
You’ll need to submit proof of hours, pay fees ($50–$300), and schedule your test through your state’s licensing board.
4. Gain Additional Experience for Master License (Optional but Recommended)
To become a master plumber (required to pull permits or start a business), most states ask for 1–2 more years of journeyman-level work.
Total time to master license: 5–7 years
Master exam covers advanced systems, business law, and complex code interpretation

Enroll in an accredited trade school: Some programs (like those at Lincoln Tech or UTI) offer accelerated curricula that count toward apprenticeship hours.
Track hours meticulously: Use digital logs (e.g., Workiz or ServiceTitan) to avoid delays during application.
Study early: Use resources like PSI Exams or ICC study guides 3–6 months before your test.
Choose a high-demand state: States with labor shortages (e.g., Arizona, Nevada) may offer faster processing or reciprocity.
However, never skip required hours—doing so risks license denial or legal penalties.
Common Mistakes That Delay Licensing
Avoid these pitfalls:
❌ Not verifying state-specific requirements (e.g., Alaska requires cold-climate training)
❌ Missing continuing education deadlines (some states require CE for renewal)
❌ Failing to renew apprentice registration annually
❌ Underestimating exam difficulty—many fail due to poor code knowledge
FAQ: Your Top Questions Answered
Q1: Can I get a plumbing license without an apprenticeship?
A: Almost never. All 50 states require documented hands-on experience. A few (like Connecticut) allow military veterans to substitute service hours, but formal training is still needed.
Q2: How much does it cost to get a plumbing license?
A: Total costs range from $500 to $2,500, including:
Apprenticeship fees (often employer-covered)
Exam fees ($75–$200)
Application/license fees ($50–$300)
Study materials ($100–$400)
Q3: Do I need a license to do plumbing work in my own home?
A: Usually no—most states exempt homeowners doing work on their primary residence. But if you’re paid or working on rental/investment properties, a license is required.
Q4: Can I transfer my plumbing license to another state?
A: Sometimes. States like Alabama, Georgia, and North Carolina have reciprocity agreements. Others require you to pass a local exam or complete additional hours. Always check with the new state’s licensing board.
Q5: What’s the difference between journeyman and master plumber licenses?
A: A journeyman can install and repair systems independently. A master plumber can design systems, pull permits, supervise others, and own a plumbing business. Master status typically requires 1–2 extra years of experience.
Q6: Is plumbing school worth it?
A: Yes—if it’s accredited and tied to a registered apprenticeship. Standalone “diploma mills” won’t count toward licensing. Look for programs registered with the U.S. Department of Labor.
