The Hawaii Department of Commerce and Consumer Affairs Professional and Vocational Licensing Division regulates 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). Becoming licensed as a plumber requires years/hours of plumbing work in compliance with the Uniform Plumbing Code (UPC).
Hawaii Plumbing License Reciprocity
Hawaii does not have reciprocal agreements with any other states. All applicants must meet the same licensing and examination requirements.
Hawaii Plumbing License Requirements
There are two types of plumbing licenses in the state of Hawaii. You may seek on-the-job training or work as an apprentice to earn the hours to become a journey worker plumber. Once you have gained your journey worker license, you may begin accumulating hours to become a master plumber.
To apply for a plumbing license, you must fill out the plumbing sections of the application. You must also fill out an experience verification application that must also be signed by your employer and notarized.

A master plumber (MP) must complete two years (or equivalent) work as a licensed journey worker. You must also pass the plumbers’ examination.
A journey worker plumber (PJ) must complete 5 years with no less than 10,000 hours of plumbing work that is in compliance with the Uniform Plumbing Code (UPC). This plumbing work may be performed through an apprenticeship by an employer with on-the-job training, or a union apprenticeship.
