7. Describe the general purpose of these rules, including any problems the changes are intended  
to address.  
The proposed rules will adopt by reference the 2024 edition of the International Plumbing Code  
(IPC), with amendments, deletions, and additions deemed necessary for use in Michigan. Part 7.  
of the Construction Code currently adopts by reference the 2021 edition of the IPC, which is based  
on plumbing principles used in plumbing codes across the country. Part 7. also includes rules that  
amend the IPC to address plumbing practices that are specific to Michigan and delete those  
requirements in the IPC that do not pertain to Michigan because of the state’s geographic and  
environmental features.  
The proposed rules provide the latest standards to protect the health and promote the safety and  
welfare of the State of Michigan residents by regulating the installation and inspection of  
plumbing within the state.  
Adoption of the 2024 edition of the IPC, as well as an update of the rules, could result in a cost  
savings for homeowners and contractors who will be able to use the latest materials and  
technology as a result of the revision of the rules.
