The Hawaii Department of Commerce and Consumer Affairs Professional and Vocational Licensing Division is in charge of all the rules and regulations related to the licensure for vocational trades including general contracting, licensed electricians, and licensed plumbers.

There are two types of licensure for plumbers in Hawaii: a journey worker license (PJ), and a master plumber (PM).

So as to become a Master Plumber you must complete two years of work as a licensed journey worker and pass the plumbers’ examination.

To be a journey worker plumber, you must complete 5 years with no less than 10,000 hours of plumbing work that is in compliance with the Uniform Plumbing Code (UPC) which can be performed through an apprenticeship by an employer with on-the-job training, or a union apprenticeship.

Hawaii Plumbing License Reciprocity

Hawaii does not have reciprocal agreements with any other states.

So as to work in Hawaii, all applicants must meet the same licensing and examination requirements.

You can make a choice between two types of plumbing licenses in the state of Hawaii.

To become a journey worker plumber you will need to have on-the-job training or work as an apprentice to earn the hours.
