Moving to Hawaii as a journeyman plumber: every state's rule

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.
