All current plumbing contractor licenses expired December 31, 2017. Instructions for renewing plumbing contractor and restricted plumbing contractor licenses are below.

Apply for or Renew a License

- During the renewal, you can review the information we have on file for your company, make changes and pay the renewal fee.

- Renewal fees cannot be paid over the telephone.

- If DLI does not have current liability insurance information for your company, you will need to submit an updated Certificate of Insurance. Insurance certificates can be emailed to DLI.license@state.mn.us

You will also need to submit a Certificate of Compliance - Minnesota Workers' Compensation to DLI.license@state.mn.us

License bond is continuous

- Bonds required for plumbing contractors and restricted plumbing contractors are continuous, so you do not have to submit bond forms with your renewal.

- The amount of the bond is also cumulative, which means there will be $25,000 in coverage for each two-year license term.

Secretary of State filing

- To renew your license, your corporate, LLC or assumed name filing with the Minnesota Secretary of State must be up-to-date.

- On all renewal forms, especially your insurance certificates, your business name must appear EXACTLY as it is filed with the Minnesota Secretary of State.

- Check the status of your Office of the Minnesota Secretary of State filing and update it if necessary. Your license cannot be renewed if your Secretary of State filing is inactive.

If you have changed your business structure (going from a sole proprietorship to an LLC or corporation, or from a corporation to an LLC), you will need to apply for a new license for your new business entity.

Paper renewal

- Download and complete the Plumbing Contractor or Restricted Plumbing Contractor License Renewal Application. Be sure to provide an email address in case DLI has questions.

- Include proof that your business filing is active. A printout of the page from the Office of the Minnesota Secretary of State showing the business filing is sufficient.

- Completed renewals can be submitted by mail or in person
