Who administers the plumbing program?

The commissioner of the Department of Labor and Industry is responsible for administering the statewide plumbing code and licensing requirements, and also for taking punitive actions against plumbers who fail to meet licensing or installation requirements. This responsibility is carried out in the Plumbing Plan Review and Inspection unit with the Department of Labor and Industry. For help with questions about plumbing codes, licensing requirements, or non-complying work, contact the Plumbing Plan Review and Inspection unit at (651) 284-5067 or dli.plumbing@state.mn.us.

• Administrative or punitive measures - DLI may take action against a plumber who does non-complying work. Possible actions against plumbers include invocation of the bond to correct non-complying work and administrative penalties through the Minn. Statutes, Section 144.989 to 144.993 that may result in monetary fines and licensure suspension or revocation penalties.
