to address.  
Part 7 of the Construction Code currently adopts by reference the 2018 edition of the International  
Plumbing Code (IPC), which is based on plumbing principles and plumbing codes across the  
country. Part 7 also includes rules that amend the IPC, address plumbing practices that are specific  
to Michigan, and deletes those requirements in the IPC that do not pertain to Michigan because of  
the State’s geographic and environmental features. The proposed rules will adopt by reference the  
2021 edition of the IPC with amendments, deletions, and additions deemed necessary for use in  
Michigan.  
The proposed rules provide the latest standards to protect the health and promote the safety and

plumbing within the state.
