The Department of Licensing and Regulatory Affairs will hold a public hearing to receive public  
comments on proposed changes to the Construction Codes - Part 7. Plumbing Code rule set.  
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 welfare  
of the State of Michigan residents by regulating the installation and inspection of plumbing within the  
state.  
The authority to promulgate the proposed rules is found in Section 4 of 1972 PA 230, MCL 125.1504 and  
Executive Reorganization Order Nos. 1996-2, 2003-1, 2008-4, and 2011-4, MCL 445.2001, MCL  
445.2011, MCL 445.2025, and MCL 445.2030.  
The proposed rules will take effect 120 days after filing with the Secretary of State. The proposed rules  
are published on the State of Michigan's website at www.michigan.gov/ARD and in the 9/1/2023 issue of  
the Michigan Register. Copies of these proposed rules may also be obtained by mail or electronic mail at  
the following email address: Lara-bcc-rules@michigan.gov.  
Comments on these proposed rules may be made at the hearing, by mail, or by electronic mail at the  
following addresses until 9/15/2023 at 05:00PM.
