Dreaming of a stable, hands-on career with strong earning potential? You’re not alone. Many New Yorkers are turning to skilled trades like plumbing—and for good reason. With growing infrastructure needs and a shortage of qualified professionals, how to become a licensed plumber in NY is a question more people are asking every day. Whether you’re fresh out of high school or switching careers, this guide walks you through every requirement, timeline, and insider tip to get licensed and start working legally in New York State.
What Are the Basic Requirements to Become a Licensed Plumber in New York?
Before diving into training or exams, you must meet New York State’s eligibility criteria:
Be at least 17 years old (to register as an apprentice)
Hold a high school diploma or GED
Be legally authorized to work in the U.S.
Pass background checks (required in some counties, especially NYC)
Note: New York does not issue a single statewide plumbing license. Instead, licensing is handled at the county or city level—most notably by the New York City Department of Buildings (DOB) and county health departments elsewhere. This means requirements can vary slightly depending on your location.
💡 Pro Tip: If you plan to work in NYC, you’ll need a Master Plumber License or work under one. Outside NYC, many counties accept the New York State Journeyman Plumber Certification, though local permits may still apply.
Step-by-Step: How to Become a Licensed Plumber in NY
Step 1: Complete a High School Diploma or Equivalent
A high school diploma (or GED) is the minimum educational requirement. Focus on math, science, and shop classes—they build foundational skills for reading blueprints, calculating pipe angles, and understanding water pressure systems.
Step 2: Enroll in a Plumbing Apprenticeship Program
New York requires 4–5 years of hands-on training under a licensed plumber. The most common path is through a registered apprenticeship, which combines:
8,000+ hours of on-the-job training
576+ hours of classroom instruction
Top programs include:
UA Local 1 Plumbers Union (New York City)
Associated Builders and Contractors (ABC) Empire Chapter
New York State Department of Labor–approved apprenticeships
These programs are often tuition-free (sponsored by unions or contractors) and pay you while you learn—starting around $20–$25/hour, with raises as you progress.
Step 3: Gain Work Experience
During your apprenticeship, you’ll assist with:
Installing pipes, fixtures, and water heaters
Reading plumbing schematics
Adhering to the New York State Uniform Fire Prevention and Building Code
Keep detailed logs of your hours—your licensing board will require proof.
Step 4: Apply for the Journeyman or Master Plumber Exam
After completing your apprenticeship, you can sit for the exam. In NYC, you must first become a Journeyman Plumber, then gain 3+ years of experience before applying for a Master Plumber License.
Processing takes 4–8 weeks. Upon approval, you’ll receive your license—valid for 3 years and renewable with continuing education.

Years 1–5: Apprenticeship + classroom training
Year 5: Take Journeyman exam (outside NYC)

Common Mistakes to Avoid
Skipping local code training: NYC’s plumbing code is stricter than the national standard.
Not tracking work hours: Incomplete logs = delayed licensing.
Assuming a license transfers: A license from Buffalo isn’t valid in Brooklyn.
Ignoring continuing education: Renewal often requires safety or code update courses.
