Licensing
Do you need a license in Saint Louis?
Licensing for odor control work is set at the state and local level in Missouri, and Saint Louis 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: Deodorization and odor control work is generally not separately licensed in Missouri or most states. A local business license may still apply depending on your city or county, so confirm current requirements with your municipality. A NISCR certificate verifies your 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.
