Online renewal

Renew your license online here

You can review the information DLI has on file for your company, make changes and pay the renewal fee, all online.

Renewal fees cannot be paid over the telephone.

Your original bond forms will still have to be mailed to our agency at 443 Lafayette Road, St. Paul, MN 55115. 

If DLI does not have current liability insurance information for your company, you will need to submit a current insurance certificate. Insurance certificates can be emailed to

Secretary of State filing

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

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

Check the status of your Secretary of State filing here and update it if necessary.

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

License renewals can be submitted by mail or in person.

Mailed or delivered renewals must include all of the forms included in the Water conditioning contractor license application packet

Secretary of State filing must be current - provide proof that your business filing is active. A hard copy of the page on the Secretary of State's website showing the business filing is sufficient.

Providing an email address helps us communicate with you immediately if there is an issue with your renewal, allowing your application to be processed as quickly as possible.

Bond issues

To ensure that your renewal is processed without delay, please review these items relating to the required $3,000 surety bond:

Be sure your insurance agent has used the correct bond form

The name of your company must be listed on the bond exactly the same way it appears on your license (which must be the same way it is filed with the Secretary of State).

An owner or officer of your company must sign the bond in front of a notary public:

The notary public must verify the signature of your company's owner or officer in the appropriate "Acknowledgment of Principal" section on the second page of the bond form (Section A for individual proprietors, partnerships and LLCs, or Section B for corporations -- Section C must be completed by the surety company):
