New York Plumbing License Requirements (Step-by-Step Process)

Understanding plumbing license requirements in New York is essential if you plan to work as a plumber, start a plumbing business, or hire licensed professionals in the state. New York does not issue a single statewide plumbing license. Instead, licensing for plumbers and plumbing contractors is regulated at the local city or county level, and requirements can vary from one jurisdiction to another. This guide explains what work requires a license, the different plumbing license types, how to qualify, business considerations, insurance, renewals, and more.

Is a Plumbing License Required in New York?

Yes. In New York, professional plumbing work generally requires a valid plumbing license issued by the city or county where you work. The state itself does not issue a single plumber license, and requirements can vary significantly based on local law.

Only minor maintenance or basic home repairs may be performed without a license. For more complex plumbing work — including system design, installations, or major repairs — a licensed plumber is required to ensure compliance with building and plumbing codes.

Types of Plumbing Licenses in New York

Most jurisdictions in New York recognize the following plumbing license categories:

Journeyman Plumber

A journeyman plumber can perform a wide range of plumbing services under general supervision and often works for licensed master plumbers or companies.

Typical requirements include:

• Minimum age of 18 years old
• Completion of an approved plumbing apprenticeship or equivalent on-the-job experience
• Proof of supervised work under a licensed plumber
• Submission of work history and affidavits from supervising plumbers
• Fees set by the local licensing board (commonly $50–$100, depending on the jurisdiction)

Journeyman requirements vary by city or county, so always check with the applicable local authority.

Master Plumber

A master plumber license allows you to perform all plumbing work independently, supervise other plumbers, design plumbing systems, and operate a plumbing business.

Common qualifications include:

• Several years of plumbing experience (often at least seven years), including time worked as a journeyman
• Passing a master plumber examination that may include trade knowledge, business practices, and codes
• Submission of proof of experience and work history
• Payment of surety bonds and application fees
• Background checks in some jurisdictions

Local requirements for master plumbers can be more stringent in major cities like New York City, where specific experience pathways or advanced qualifications may be required.

How to Get a Plumbing License in New York

Because licensing authority is local, the specific steps depend on where you plan to work. However, the general progression typically includes:

1. Apprenticeship and Training
Begin with an apprenticeship or on-the-job training under a licensed plumber. This stage builds the foundational skills and work hours needed for licensure.

2. Apply for the Journeyman License
After completing required training hours and apprenticeships, submit your application, documentation of experience, and any required affidavits to the local licensing board.

3. Gain Experience as a Journeyman
Work independently or under supervision to build additional experience required for higher licensure.

4. Apply for Master Plumber License
When you meet experience and other requirements, submit a master plumber application, pay fees, pass exams as required, and provide documentation of work history and bonds.

Business Registration and Insurance

Even with a master plumber license, operating a plumbing business in New York typically requires:

• Business registration with the New York Department of State.
• Liability insurance to protect clients and the business from property damage or injury claims.
• Additional coverage such as workers’ compensation, commercial auto, and tools and equipment insurance, depending on business size and local requirements.

License Renewal and Maintenance

Plumbing licenses in New York must be renewed regularly, usually every one to two years, depending on the municipality. Renewal often requires:

• Payment of renewal fees
• Updated proof of insurance
• Continuing education in some jurisdictions

Local boards provide specific renewal schedules and requirements, so it’s essential to track deadlines and maintain compliance.

Reciprocity and Licensing Transfers

There is no statewide reciprocity system in New York for plumbing licenses. Licenses issued by one city or county generally do not automatically authorize work in another. Some municipalities may have agreements with nearby jurisdictions, but you should confirm requirements with each local licensing authority before working outside your primary area.

Plumbing License Requirements in New York City (NYC)

New York City has some of the strictest plumbing licensing requirements in the state. Anyone performing plumbing work in NYC must comply with rules set by the NYC Department of Buildings (DOB).

Why Local Licensing Matters in New York

Because New York plumbing licenses are issued locally, being licensed in one city does not automatically allow you to work in another. NYC, Albany, and Buffalo each have:

If you plan to work across multiple cities, you must verify and maintain compliance in each jurisdiction.
