Licensing
Do you need a license in Minnesota?
Odor control and deodorization are generally not separately licensed in Minnesota. If the broader job involves restoration repairs or remodeling, contractor licensing through the Minnesota Department of Labor and Industry could apply, and a local business license may be required to operate. Requirements change, so verify current state and local rules before taking on work. A NISCR certificate documents professional training and is not a government 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.
