Who enforces the plumbing code in Minnesota?

Our agency administers the statewide plumbing code and licensing requirements, and also takes administrative actions against plumbers who fail to meet licensing or installation requirements. 

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

We cannot require plumbers to resolve customer disputes, pay damages or take corrective action unless violations of the Minnesota Plumbing Code are discovered. In some cases, disputes must be resolved through private civil action (the court system).
