Licensing
Do you need a license in Nashville?
Licensing for odor control work is set at the state and local level in Tennessee, and Nashville may add its own business-license or registration requirements on top. Always confirm current city and county rules before bidding work. For the statewide picture: Odor control and deodorization are technical skills and are generally not separately licensed in Tennessee. That said, deodorization is usually performed as part of a larger restoration project, and those broader jobs can fall under Tennessee contractor licensing at the $25,000 threshold or a county Home Improvement license. Your NISCR certificate is a professional credential, not a government license. Always confirm current state and local requirements with the Tennessee Board for Licensing Contractors before performing regulated restoration work.
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.
