If you are a Mechanical Contractor who will be performing work that requires an Mechanical Permit under the Michigan Mechanical Code or Michigan Residential Code, you will need to apply for a permit to ensure the work is completed properly.
If you're a homeowner of a single-family home, you may apply for a Mechanical Permit for your primary residence in person at the Development Center. If you're a homeowner AND licensed mechanical contractor, you may apply online for a Mechanical Permit. Properites with 2 or more units must use a licensed contractor.
