Hawaii trade license reciprocity

Hawaii issues a statewide Journey Worker Electrician (EJ) license through the Board of Electricians and Plumbers in the Department of Commerce and Consumer Affairs, and under HAR §16-80-4 anyone who performs electrical work in the state must hold it (or work under a licensee who is physically present). Eligibility under HRS §448E-5(b) is five years full-time and not less than 10,000 hours of residential or commercial wiring experience under a journey worker or supervising electrician, plus 240 hours of electrical academic coursework accepted by a University of Hawaii community college, followed by the PSI-administered open-book Hawaii exam. Narrower journey-level classes exist for industrial (EJI, 8,000 hours), specialty/low-voltage (EJS, 6,000 hours) and maintenance (EM) electricians. 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 work experience counts in full when verified by the licensed electrician (or, where that state licenses only contractors, the licensed contractor) under whom it was earned. Licenses run on a three-year cycle ending June 30 (2026, 2029, 2032) and renewal requires an NEC update course.

Hawaii's highest personal electrician credential is the Supervising Electrician (ES) license, which HAR §16-80-4 requires of anyone who directs or supervises electrical work; Hawaii does not use the title 'master electrician' for electricians (the term is used only for plumbers). Under HRS §448E-5(b)(3) an ES applicant must have been registered with the Board as a journey worker electrician for at least four years or have equivalent experience in the trade, and must pass the PSI-administered supervising electrician exam. HAR §16-80-3 and the Board's application form define equivalent experience to include having been licensed as a journey worker or supervising-level electrician for at least four years in another county, state or country whose licensure requirements are substantially equivalent to Hawaii's, so an out-of-state journeyman or master license can satisfy the four-year prerequisite, but Hawaii does not reciprocate with any jurisdiction and the Hawaii exam is never waived. Parallel supervising classes exist for industrial (ESI, three years) and specialty (ESS, two years) electricians. A contractor's license under HRS ch. 444 is separately required to contract for electrical work. Licenses renew every three years by June 30 with an NEC update course.

Hawaii does not license journeyman HVAC mechanics, HVAC technicians or refrigeration technicians. The Department of Commerce and Consumer Affairs licenses only contractors for this work, through the Contractors License Board's specialty classifications C-52 Ventilating and Air Conditioning Contractor and C-40 Refrigeration Contractor (systems below 50°F), and its directory of boards and programs contains no HVAC or refrigeration technician program; the Board of Electricians and Plumbers licenses only electricians and plumbers. HRS §444-9.5 obliges electrical and plumbing contractors to employ individually licensed workers, but no equivalent rule applies to ventilating, air-conditioning or refrigeration contractors, so their mechanics work under the contractor's license without any personal credential, and no county trade license was found. An out-of-state journeyman or HVAC technician license therefore has nothing to transfer to in Hawaii and is neither required nor recognized for employment, although the Board will accept it as proof of licensure alongside supervisory experience when the holder later applies for a contractor license. EPA Section 608 technician certification is a federal requirement for anyone handling refrigerants and applies in Hawaii as everywhere else. A mechanic who wants to contract independently must qualify for a C-52 or C-40 license, described at the master level.

Hawaii issues no master HVAC or master refrigeration license. The highest HVAC credential is a Contractors License Board specialty license in classification C-52 Ventilating and Air Conditioning (warm-air heating, cooling, ventilating and air-conditioning systems, including heat pumps) or C-40 Refrigeration (below 50°F), issued to a sole proprietor or to a contracting entity that qualifies through a responsible managing employee (RME); an RME holds a personal license number but may contract only for the employing entity and the principal RME must live in Hawaii while the license is active, so the credential functions as a business license rather than a master's card. A master HVAC licensee who only wants to work for an employer needs no Hawaii license. To contract, the sole proprietor or RME must document at least four years of supervisory experience as a foreman, supervising employee or contractor within the past ten years with three notarized experience certificates and a project list, file the $50 application with a CPA financial statement, credit report and tax clearance for Board review at a monthly meeting, then pass the PSI-administered Part I Business and Law and Part II trade exams within six months of approval; on passing, the licensee provides liability insurance (at least $100,000 per person and $300,000 per occurrence bodily injury and $50,000 property damage), workers' compensation coverage, a Hawaii place of business and the license fee, and renews by September 30 of even-numbered years ($338 entity or sole proprietor, $208 RME for 2026-2028). The Board's FAQ states that Hawaii has no reciprocity agreements with any state and that all applicants must meet the same licensing and examination requirements; an out-of-state contractor or master license is accepted only as supporting proof of experience, and HAR §16-77-41 waives the exam solely for someone who already passed the Hawaii exam in the same classification within four years. The 2018 FAQ listed the exam fee at $75 per part and initial license fees of $663 (entity or sole proprietor) and $438 (RME) in the first year of the biennium, which the current form no longer prints. EPA Section 608 certification remains a separate federal requirement for handling refrigerants.
