How to get a Minnesota Plumbing Contractor License

This Minnesota plumbing contractor license guide is for informational purposes only. SuretyBonds.com does not regulate or manage licensing for plumbing contractors in Minnesota. Contact the Minnesota Department of Labor and Industry for the state's latest official plumbing contractor license requirements. 

The Minnesota Department of Labor and Industry defines a plumbing contractor as "a person who may contract to perform or offer to perform plumbing work in all areas of the state provided the contractor has at all times a licensed master plumber as a responsible individual and maintains compliance with the required bond, general liability insurance and workers' compensation insurance requirements (Minnesota Statute 326B.46)."

Individuals who fit this definition must file and maintain a Minnesota plumbing contractor license if they work in a city with a population that's more than 5,000. If the city you work in has a population that's fewer than 5,000, you'll need a restricted plumbing contractor license.

Complete the following steps to apply for your regular or restricted Minnesota plumbing contractor license.

How do I get a plumbing contractor license in Minnesota? 

Step 1. Verify you're qualified to be a plumbing contractor in Minnesota.

  • Be at least 18 years old
  • Hold an active master plumber's license    
  • Be responsible for all work done by your plumbing company's employees

You must purchase workers' compensation insurance in the following minimum coverage amounts.

  • At least $50,000 per person

Your liability insurance can be an Acord certificate or a DLI-approved certificate. Your policy must be for “premises, operations and products, and completed operations.”

Step 3: Purchase your Minnesota plumbing contractor surety bond.

The Minnesota Department of Labor and Industry requires that plumbing contractors file a $25,000 Minnesota plumbing contractor bond with their state plumbing contractor license application. This bond specifically requires Minnesota plumping contractors to faithfully and lawfully perform all duties and comply with all laws and rules pertaining to their licenses, permits, and contracts.

You can buy your Minnesota plumbing contractor bond online 24/7 for $125 annually. Once your order has been processed, your official Minnesota plumbing contractor bond will be emailed to you.

Step 4. Fill out your ownership disclosure form.

You must disclose all business owners, officers, partners, and members of your plumbing business. You'll need to submit a separate, completed Disclosure of Business Owners, Partners, Officers, and Members form for each individual. 

Step 5: Submit your Minnesota plumbing contractor license application with required fees. 

You'll apply for your Minnesota plumbing contractor license through the iMS License Management System where you'll upload all required forms electronically and pay your $188 application fee. The Minnesota Department of Labor and Industry will issue your license by email once your application has been approved.

How do I renew my Minnesota plumbing contractor license? 

Minnesota plumbing contractor licenses expire on December 31st of odd-numbered years. You can renew your license through the same IMS application portal where you applied for your initial license. To renew your license, you'll need to submit your plumbing contractor renewal form and pay a $188 renewal application fee. If you're renewing your Minnesota plumbing contractor license after its December 31st expiration date, you must pay an additional $90 fee.
