Licensing
Do you need a license in Michigan?
In Michigan, garage door repair is often treated as service work, but installation can fall under residential builder or maintenance/alteration contractor rules depending on the scope, and some municipalities require permits. The line between repair and installation matters for licensing. Always verify current state and local requirements with LARA and your local building department before installing doors. A NISCR certificate is a professional training credential, not a government-issued contractor license.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
