Below is a letter recently sent to licensed boiler installers in Michigan. It is presented below as installers may find it enlightening to know there are rules that even the local jurisdictions are to follow.
The State of Michigan's Boiler Division is aware that some jurisdictions are requiring local contractors to obtain permits for the installation of boilers in commercial locations in addition to the State of Michigan permits for venting and fuel gas piping.
1972 PA 230 (commonly referred to as the 'Construction Code Act') does not give the Local Jurisdictions the authority to issue permits for the installation of boilers in commercial locations. Similarly, PA 407 of 2016 authorizes only the State of Michigan, Bureau of Construction Codes, to issue permits for the installation of boilers in commercial locations.
The one exception to this statement, however, would be MCL 339.5947 which reads, "This article does not apply to or in any city that has a population of 600,000 or more according to the most recent decennial census". Except for the City of Detroit, no other jurisdiction has such a population base. For that reason, the Local Jurisdictions do not have the authority to enforce any requirements regarding the issuance of permits for boilers.
Except for the City of Detroit, Local Jurisdictions may not engage in the practice of issuing permits for the installation of boilers in commercial locations.
If you have any questions or if a local jurisdiction has required you to pull a permit for boiler installation in a commercial location, please contact the Boiler Division at 517- 241-9334.
