Moving to North Dakota as a master plumber: every state's rule

North Dakota issues a statewide Master Plumber certificate and license through the North Dakota State Plumbing Board under NDCC chapter 43-18 and NDAC chapter 62-02-01. Any firm installing plumbing where there is a public water or sewer system must have a licensed master plumber in charge (NDCC 43-18-10). A new applicant must be at least 21 and have two years and 3,400 hours of experience 'as a journeyman plumber licensed by the state of North Dakota or any other state that has a state licensing law', then pass the board-administered master exam - four parts, one closed book and three open book, five hours, on the 2018 North Dakota Plumbing Code - with 80%. Fees are a $50 combined application and exam fee and a $200 master license fee paid on passing; licenses expire every December 31 and renew for $200, with 2 to 4 hours of continuing education required in each two-year period. A master may also hold the journeyman license without paying the journeyman fee. Masters from Minnesota (license held one year) and South Dakota Contractor licensees may be licensed without examination under the Board's written agreements; other out-of-state masters apply for the North Dakota master examination with their journeyman or master license vouched for.
