Licensing
Do you need a license in Seattle?
Licensing for odor control work is set at the state and local level in Washington, and Seattle 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 generally not separately licensed in Washington and are usually performed as part of broader cleaning or restoration services. A local business license may still apply where you operate. This is general guidance only, so confirm current city, county, and state requirements before offering paid services.
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.
