Licensing
Do you need a license in Columbus?
Licensing for odor control work is set at the state and local level in Ohio, and Columbus 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 are generally not separately licensed in Ohio. When odor work is part of a larger fire, water, or mold job, the broader project may fall under contractor or local rules, so consider your full scope. As always, verify current state and local requirements before working. A NISCR certificate documents professional training and is not a government-issued 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.
