We license and regulate all plumbing work performed in Minnesota and investigate complaints related to plumbing work to determine whether violations of the state laws and rules governing the plumbing industry have occurred. When violations are proven, we take enforcement actions that can include fines and license revocation.

We are unable to require plumbers to resolve customer disputes, pay damages, or take corrective action unless violations of the Minnesota Plumbing Code are discovered. And in some cases, disputes must be resolved through private civil action (the courts).

File a complaint

Complaints can be filed by consumers, business owners, other plumbers or inspectors.

Typically, we send a copy of the complaint to the plumber with a request for a written response to the complaint. A copy of the plumber's response is then provided to the person who submitted the complaint.
