Plumber License from Illinois to New Jersey: Does It Transfer? (2026)
Does New Jersey accept an Illinois plumbing license?
A plumbing license transfers from Illinois to New Jersey by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the New Jersey State Board of Examiners of Master Plumbers (Division of Consumer Affairs), verify your Illinois license, and meet New Jersey's endorsement requirements. New Jersey's master-plumber licensure-by-reciprocity provision (N.J.S.A. 45:14C-19) can waive the NJ Master Plumber examination only for an applicant from a state whose standards the Board finds comparable AND that reciprocates with New Jersey; as of the Board's published reciprocity list (06/18/19) NO state qualifies (every state evaluated was denied, none granted), so in practice all out-of-state plumbers must pass the New Jersey Master Plumber exam. Journeyman applicants are not exam-waived.

Verdict
Licensure by endorsement
Illinois is not among the states New Jersey names for an exam waiver, so this move runs on the New Jersey State Board of Examiners of Master Plumbers (Division of Consumer Affairs)'s individual endorsement or equivalency review rather than a guarantee. Bring your Illinois license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
What's different between Illinois and New Jersey
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into New Jersey. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
Illinois to New Jersey (this page): Licensure by endorsement.
New Jersey to Illinois (the reverse move): Full re-application.
The two directions differ: Illinois and New Jersey do not give each other's licensees the same route.
- Does coming from Illinois matter?
Illinois gets New Jersey's most common result: 41 of 50 origins (the other 49 states and DC) get the same one, so for most movers the origin does not change the answer.
The others get: no state license to transfer (9).
- Application fee
New Jersey lists $75–$100 for an out-of-state applicant and Illinois lists $225 for the reverse move; neither may be the full cost.
- Exam rules on record
New Jersey and Illinois carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- New Jersey (this move): New Jersey's master-plumber licensure-by-reciprocity provision (N.J.S.A. 45:14C-19) can waive the NJ Master Plumber examination only for an applicant from a state whose standards the Board finds comparable AND that reciprocates with New Jersey; as of the Board's published reciprocity list (06/18/19) NO state qualifies (every state evaluated was denied, none granted), so in practice all out-of-state plumbers must pass the New Jersey Master Plumber exam. Journeyman applicants are not exam-waived.
- Illinois (the reverse move): Illinois requires every out-of-state plumber to pass the Illinois plumber's licensing examination; the application's out-of-state section accepts prior apprenticeship/licensure toward the four-year experience prerequisite but does not waive the exam. The only license-WITHOUT-examination pathway is for a holder of a current City of Chicago plumber's license (an intra-Illinois municipal reciprocity), not for licensees of other states

Frequently asked questions
Can I keep my Illinois plumbing license after I'm licensed in New Jersey?
Yes — plumbing licenses in different jurisdictions run independently. Keep the Illinois credential active on its own renewal and continuing-education schedule and you hold both, which is common for plumbers working near a state line.
