Dreaming of a stable, well-paid trade career in the heart of America’s biggest city? How to become a master plumber in New York City is a common—but smart—question. With over 3 million residential and commercial buildings relying on complex plumbing systems, NYC needs skilled professionals who can design, install, and repair these critical infrastructures. Whether you’re just starting out or already working as a journeyman, this guide walks you through every requirement, exam, and timeline to earn your master plumber license in NYC.
Unlike many states, NYC has its own licensing system managed by the Department of Buildings (DOB)—not the state of New York. This means even if you’re licensed elsewhere, you’ll need NYC-specific credentials to work legally within the five boroughs.
💡 Fun fact: According to the U.S. Bureau of Labor Statistics (2024), plumbers in the New York-Newark-Jersey City metro area earn a median annual wage of $78,560, with top earners making over $100,000—especially those with master licenses and their own businesses.
Step 1: Meet the Basic Eligibility Requirements
Before you can even apply, you must satisfy NYC’s strict prerequisites:
Be at least 18 years old
Have a high school diploma or GED
Possess 7 years of documented plumbing experience (with at least 2 years in NYC)
Hold a current Journeyman Plumber license issued by NYC DOB
⚠️ Note: Experience must be verified by a licensed master plumber or employer using official affidavits. Volunteer or unlicensed work doesn’t count.
Step 2: Gain Required Experience (The 7-Year Path)
Most aspiring master plumbers start as apprentices. Here’s a typical progression:
Role
Duration
Key Responsibilities
Apprentice
4–5 years
Assist journeymen, learn code compliance, attend trade school
Journeyman Plumber
2+ years
Perform installations/repairs under supervision, pull permits only under a master
Master Plumber
—
Full autonomy, business ownership, system design
NYC requires at least 7 years of full-time plumbing work, with 2 years specifically in New York City. Time spent in accredited plumbing programs (like those at New York City College of Technology) may count toward up to 2 years of experience.
📌 Pro Tip: Keep detailed logs of every job—dates, addresses, types of work, and supervising master plumbers. The DOB may audit your records.
Step 3: Apply for the Master Plumber Exam
Once eligible, submit your application to the NYC Department of Buildings:
Processing takes 4–6 weeks. If approved, you’ll receive an exam eligibility letter with scheduling instructions.
Step 4: Pass the NYC Master Plumber Exam

Step 5: Get Bonded and Insured

Only then will the DOB issue your Master Plumber License, valid for 2 years.

Common Mistakes to Avoid
❌ Assuming a NY State license works in NYC → It doesn’t. NYC has its own rules.
❌ Skipping code updates → The NYC Plumbing Code changes every 3 years. Stay current.
❌ Using unverified experience → The DOB rejects applications with incomplete affidavits.
❌ Not studying local amendments → NYC modifies the base IPC (International Plumbing Code). Know the differences.
