New Jersey Plumbing License: Everything You Need to Know

The plumbing industry in New Jersey offers lucrative opportunities for those who meet the state’s requirements for licensing. New Jersey issues only one level of license, the master plumber license, with apprenticeship and journeyman roles serving as steps toward this ultimate certification. This guide covers the types of licenses, requirements, insurance, renewal process, and resources for plumbing professionals in New Jersey.

What plumbing work can be done without a license?

New Jersey requires a master plumber license for all significant plumbing work. Minor, basic repairs may not require a license, but for any new installations, alterations, or complex repairs, only licensed master plumbers can legally operate in the state. Homeowners or businesses should hire licensed professionals to ensure compliance and quality.

What are the different types of plumbing licenses in New Jersey

New Jersey offers only one official license for plumbing: the master plumber license. However, apprenticeships and journeyman roles serve as essential stages in the journey to becoming a licensed master plumber.

1. Apprentice Plumber: The entry-level stage, where individuals learn the basics of plumbing through a mix of classroom instruction and supervised work experience.
2. Journeyman Plumber: After completing an apprenticeship, plumbers can work independently on some tasks but are still generally supervised by a master plumber.
3. Master Plumber: The only fully licensed level in New Jersey, master plumbers can work independently, design plumbing systems, and supervise apprentices and journeymen.

Licensing Requirements:

• Apprentice Plumber: Must enroll in a state-approved apprenticeship program and work under a licensed master plumber.
• Journeyman Plumber: Complete a four-year apprenticeship and gain one year of work experience as a journeyman.

Master Plumber: Applicants must be at least 21 years old, complete the required training and experience, and pass the state-administered master plumber exam, which includes sections on trade skills, business practices, and state plumbing laws. A $100 application fee is required, along with a $3,000 surety bond.

How to get a plumbing license in New Jersey

The State Board of Examiners of Master Plumbers handles plumbing licenses through the New Jersey Division of Consumer Affairs. There are two paths to becoming a licensed plumber in New Jersey.
