Plumber License in New Jersey - Exam Required

What the New Jersey Plumber Record Shows

New Jersey requires plumber contractors to hold a Master Plumber License before performing licensed work. Of 47 US states that license plumber work, New Jersey's regime applies a partial screen, combining some but not all of the exam, bond, and insurance requirements seen in peer states. Licensing is administered through the New Jersey Division of Consumer Affairs, which issues the credential, maintains the public license roster, and adjudicates consumer complaints.

The specific entry requirements for plumber contractors in New Jersey are: a qualifying exam, 4 years of documented work experience, no surety bond, liability insurance with at least $300K in coverage, and 6 hours of continuing education per renewal cycle. License fees in this classification run $50-$250. Additional notes from the licensing board: Journeyman to master pathway. Some states also require contractor registration.

For homeowners in New Jersey, verification is straightforward: use New Jersey Division of Consumer Affairs's official license lookup to confirm the license number is active, matches the contractor's legal business name, and has no disciplinary history attached. Ask for a copy of the license and the certificate of insurance before signing a contract, and request the surety bond provider if bonding is required. If defective work or non-performance occurs, the state complaint process is the formal path to recovery, file promptly, document everything, and retain copies of contracts, invoices, and correspondence.
