Michigan Plumbing Code Update | What Changed & Why

July 29, 2022 Update

Regarding the Michigan Plumbing Code Update Continuing Education requirement, the Michigan Bureau of Construction Codes stated the following:

Due to recent internal changes regarding the requirements and adoption of approved courses pertaining to updates and/or changes in the State Construction Code, the Bureau of Construction Codes has issued a one-time allowance for an extension in completing the required courses.

Both Journey and Master Plumbers must be able to provide proof, if audited, of attendance at a course approved by the Plumbing Chief, and show it was completed by March 31, 2023. Proof must state a completion date on or before 3/31/2023.

Plumbers now have until March 31, 2023, to complete the code update course!


On September 15, 2021, the Michigan Licensing and Regulatory Affair Plumbing Board adopted a new Michigan Plumbing Code. This adoption also created a new code update continuing education (CE) course requirement for all licensed Journeyman and Master plumbers.

Before we continue, it’s important to note that this code update CE requirement is not related to the April 30 license renewal deadline. It’s a unique requirement that comes along every time there’s a code update.

With that in mind, let’s discuss the code update, how updates are approved, and our new online course package!

New Michigan Plumber Code Update

Michigan plumbers now have until September 15, 2022 March 31, 2023 to complete a state-required code update course based on the 2018 International Plumbing Code (IPC).

Why Did The Code Change?

Every three years or so, the International Code Council (ICC) recommends code changes based on new developments that safeguard the health and safety of plumbers and the public. 

These code change suggestions are then published for feedback from the public and organizations such as the American Society of Plumbing Engineers.

Once the ICC approves the code changes and publishes an updated International Plumbing Code book, Michigan reviews the updated code book and amends it to apply to Michigan plumbers specifically. This new Michigan Plumbing Code is what all licensed plumbers must use.

Michigan Plumbing Code Changes

The Michigan Plumbing Code amendments focus on Part 7 of the 2018 IPC. The Michigan-specific changes include:

  • Sanitary system installation
  • Hot water piping installation
  • Permit Exceptions
  • And more

These Michigan amendments are why all licensed plumbers in Michigan must take a state-approved code update course before September 15, 2022 March 31, 2023.

Luckily, you can complete this required course from home!
