Licensing
Do you need a license in Colorado?
Odor control and deodorization are generally not separately licensed activities in Colorado; they are specialized skills usually performed as part of broader restoration work. If your odor jobs accompany fire, water, or mold remediation, those underlying services may carry local or contractor requirements. Confirm current rules with DORA and your local building department before working. Your NISCR certificate is a professional credential that documents training, 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.
