Dreaming of a stable, hands-on career with strong earning potential? You’re not alone. Many Americans are turning to skilled trades like plumbing—especially in high-demand states like New Jersey. If you’ve ever asked yourself, “How do I become a plumber in New Jersey?”, you’re in the right place. This guide walks you through every step, from training to licensure, with real data and expert-backed advice to help you succeed.
Why Choose Plumbing in New Jersey?
Before diving into the “how,” it’s worth understanding the “why.” Plumbing isn’t just about fixing leaks—it’s a recession-resistant, in-demand profession with excellent growth prospects.
According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers, pipefitters, and steamfitters is projected to grow 5% from 2022 to 2032, faster than the average for all occupations. In New Jersey specifically, aging infrastructure and strict building codes create consistent demand for licensed professionals.
The average salary for a journeyman plumber in New Jersey is $68,000–$85,000 per year, with master plumbers often earning over $100,000, especially in urban areas like Newark, Jersey City, and Princeton.
💡 “Plumbing offers job security, flexibility, and the satisfaction of solving real-world problems every day,” says Maria Lopez, a licensed master plumber and instructor at the New Jersey Plumbing & Heating School.
Step 1: Meet Basic Eligibility Requirements
To begin your plumbing journey in New Jersey, you must meet these baseline criteria:
- 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 (required for licensing)
No prior experience is needed to start—many plumbers begin with zero knowledge and train on the job.
Step 2: Complete a Plumbing Apprenticeship or Trade School Program
New Jersey does not require formal education to become a plumber, but hands-on training is mandatory before you can get licensed. You have two main paths:
Option A: Registered Apprenticeship (Recommended)
- Duration: 4–5 years
- Structure: 8,000+ hours of paid on-the-job training + 576+ hours of classroom instruction
- Sponsored by: Unions (like UA Local 68) or non-union contractors
- Cost: Typically free or low-cost (you earn while you learn)
Option B: Trade School or Vocational Program
- Duration: 1–2 years
- Examples: Lincoln Tech (Edison, NJ), Ocean County College, Bergen Community College
- Cost: $5,000–$20,000 (financial aid often available)
- Pros: Faster entry, structured curriculum
- Cons: Less real-world experience; you’ll still need field hours for licensing
✅ Pro Tip: Combine both! Many students attend trade school while working as an apprentice to accelerate their path.

Step 3: Gain Required Work Experience
To become a licensed journeyman plumber in New Jersey, you need 4 years (8,000 hours) of documented plumbing experience under a licensed master plumber.
Keep detailed records:
- Dates of employment
- Employer name and license number
- Types of work performed (residential, commercial, gas, etc.)
The New Jersey Division of Consumer Affairs – Board of Examiners of Master Plumbers reviews this documentation during your license application.
Step 4: Pass the New Jersey Journeyman Plumber Exam
Once you’ve completed your hours, you can apply to take the Journeyman Plumber Examination.
- Exam fee: $110
- Format: 100 multiple-choice questions
- Time limit: 4 hours
- Passing score: 70%
- Topics covered:
- New Jersey Plumbing Code (based on the International Plumbing Code)
- Drainage, venting, water supply, gas piping
- Safety, backflow prevention, fixture installation
Study resources:
- NJ Plumbing Code Book (available via ICC )
- Practice exams from PSI Services (the official test provider)
- Prep courses from local trade schools
📌 Note: You must apply through the New Jersey Division of Consumer Affairs and receive approval before scheduling your exam.
Step 5: Get Licensed and Start Working
After passing the exam, you’ll receive your New Jersey Journeyman Plumber License. Now you can:
- Work independently on residential and light commercial jobs
- Pull permits (under a master plumber’s supervision)
- Earn higher wages than unlicensed helpers
To advance further, consider becoming a Master Plumber after 5 additional years of experience and passing a more advanced exam.
