Plumber License Renewal Minnesota Guide

Completing your plumber license renewal in Minnesota on time ensures that your credentials remain active and compliant with state standards. The Minnesota Department of Labor and Industry - Construction Codes and Licensing Division oversees all plumbing credentials in the state. Whether you hold a Journeyworker or Master license, understanding your specific deadlines, continuing education hours, and fees will keep your renewal process smooth and stress-free.

Renewal Cycle & Expiration Dates

Plumbing licenses in Minnesota follow a fixed 2-year renewal cycle, expiring on December 31. However, the specific year depends on your license classification:

• Journeyworker Plumbers: Expire on December 31 of odd-numbered years.
• Master Plumbers: Expire on December 31 of even-numbered years.

Continuing Education (CE) Requirements

Before submitting your renewal application, you must complete the mandatory continuing education coursework:

• Total Required Hours: 16 hours every 2 years.
• Subject Requirement: A minimum of 8 hours must be dedicated specifically to the State Plumbing Code.

Make sure your courses are approved by the Minnesota Department of Labor and Industry so your credits are counted toward your renewal.

Step-by-Step How to Renew Your Minnesota Plumber License

1. Verify Your Expiration Year: Check whether your license is due on December 31 of the current year based on your license category (odd years for Journeyworkers, even years for Masters).
2. Complete Your Continuing Education: Finish your 16 hours of approved CE, making sure at least 8 hours cover the State Plumbing Code.
3. Submit Your Renewal Application: Access the online licensing portal or submit your renewal documentation through the Minnesota Department of Labor and Industry.
4. Pay the Renewal Fee: Submit the non-refundable fee ($53 for Journeyworkers or $93 for Masters).
5. Confirm License Status: Verify that your renewed license status shows active on the state database before your current credential expires.

What Happens If You Renew Late?

Allowing your plumbing license to lapse creates compliance risks. Working with an expired license is a violation of state regulations, and failing to renew by December 31 may lead to administrative complications, additional reinstatement requirements, or delays in your ability to perform permitted work. If your license has already expired, contact the Construction Codes and Licensing Division directly at 651-284-5034 to review the appropriate steps for returning your license to good standing.
