Maine to Hawaii: journeyman plumber license reciprocity
Hawaii has no reciprocity agreement with Maine. Your Maine experience counts toward eligibility, but you must pass the Hawaii exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journeyman: experience credited, full Hawaii exam (all states)
Nothing is waived, but your documented out-of-state hours count toward eligibility to sit the exam.
Hawaii has no reciprocity or endorsement for journey worker plumbers from any state. An out-of-state journeyman applies for the PJ exam like a new candidate, documenting at least 10,000 hours (five years full-time) of UPC-compliant plumbing work as a journey worker's or master plumber's helper on notarized Experience Verification forms signed by each licensed plumber who supervised the work. If the state where the experience was gained licenses only contractors, the Board accepts a form signed by the licensed contractor together with verification of that contractor's license dates, and a self-employed plumbing contractor may self-attest with a copy of the contractor license that was valid during the period claimed. The applicant must also submit a License Verification form from every jurisdiction where a license has ever been held. The $40 application goes to the Board, which meets in even-numbered months and must approve the applicant before PSI will register them; examination eligibility lasts two years. On passing, the plumber license fee is $306 in the first year of the plumber triennium, $204 in the second, and $102 in the third (calendar years listed on the 06/2026 form; 2026 is a third year, so $102 if licensed between July 1, 2026 and June 30, 2027). A Hawaii contractor's license under HRS ch. 444 is separately required to contract for plumbing work.
Board meetings are usually in February, April, June, August, October and December with exams the following month, so allow roughly two to four months from filing to exam. The current PSI examination fee is not printed on the 06/2026 DCCA form; the Board's July 2018 FAQ listed $90 for plumbers ($95 for electricians). The Board page left plumber renewal dollar amounts blank; do not treat the 2018 $276 renewal figure as current. HAR §16-80-3 recognizes county-adopted UPC as the minimum plumbing standard and allows other licensed contractors to run exterior piping five feet or more outside the building line without a PJ/PM. Equivalent-experience language in HAR §16-80-3 is written for master plumbers, not for the PJ exam.

How Hawaii licenses journeyman plumbers
Hawaii journeyman plumber · “Journey Worker Plumber (PJ)”
Statewide license
Issued by Hawaii Board of Electricians and Plumbers (DCCA Professional and Vocational Licensing Division)
Hawaii issues a statewide Journey Worker Plumber (PJ) license through the Board of Electricians and Plumbers in the Department of Commerce and Consumer Affairs. HAR §16-80-4 requires anyone who performs, directs, or supervises plumbing work in or within five feet of buildings in the State to hold a PJ or Master Plumber (PM) license (unlicensed helpers may work only while a licensee is physically present on the project site). Eligibility under HRS §448E-5(b)(5) and the Board's application is five years full-time, and not less than 10,000 hours, of plumbing work in compliance with the Uniform Plumbing Code as a journey worker's or master plumber's helper, followed by the PSI-administered Hawaii written exam based on the UPC. The Board's application form states that Hawaii does not reciprocate with any jurisdiction: an out-of-state journeyman license is never exchanged for a Hawaii license and the exam is never waived, but out-of-state hours count in full when verified on notarized Experience Verification forms. Licenses run on a three-year cycle ending June 30 (next 2027, then 2030, 2033) and Active PJ licensees must complete a 2021 UPC update course (or a board-prescribed UPC-update exam) to renew. A Hawaii contractor's license under HRS ch. 444 is separately required to contract for plumbing work.
