Restricted plumbing licenses

Since 2007, only licensed plumbing contractors or licensed restricted plumbing contractors may contract to perform plumbing work anywhere in Minnesota.

• Prior to 2007, licensing was not required for plumbing work in cities with a population under 5,000 and unincorporated rural areas.

• Contractors and individuals who perform plumbing work only in communities with a population under 5,000 must have regular or restricted plumbing licenses.

• Restricted journeyworker plumber and restricted master plumber licenses were only available between 2007 and 2009.

• No new restricted individual plumbing licenses are issued in Minnesota, though businesses may apply for a restricted plumbing contractor licenses if the business is owned by a licensed restricted master plumber or has a managing employee who holds a restricted master plumber license.
