Licensing
Do you need a license in Wisconsin?
Deodorization and odor control are generally not separately licensed in Wisconsin, so the state does not issue a specific odor-control credential. A local business license may still apply, and odor work tied to larger fire, water, or mold projects can fall under broader restoration or contractor requirements. Because rules vary by municipality and change over time, always verify current local and state requirements. A NISCR certificate is a professional credential, 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.
