If you are a homeowner who will be performing work that requires a Plumbing Permit under the Michigan Plumbing 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 Plumbing Permit for your primary residence at the Development Center. If you're a homeowner AND licensed plumbing contractor, you may apply online for a Plumbing Permit. Properties with 2 or more units are required to use a licensed contractor.
