As with general contractors in the state of Minnesota, plumbers can work under several distinct classifications, each of which requires its own license. In order to acquire the necessary plumbing license, a prospective plumber must make an application to the state, which includes proof of sufficient experience per state guidelines. They must then pass an exam and renew their license every two years. For a short period of time, the state granted restricted plumbing licenses. This option expired in 2009.
Minnesota Plumbing License Reciprocity
Minnesota has plumbing reciprocity agreements with North Dakota and South Dakota. Licensed plumbers can apply for reciprocity without an exam if they hold a license of the same level or higher compared to the reciprocal license for which they are applying. Their existing license must be current and must have been held for at least a year. They still do need to pay a $50 fee and cannot have previously failed a plumbing licensing examination in the state of Minnesota.
