Licensing
Do you need a license in Portland?
Licensing for dryer vent cleaning work is set at the state and local level in Oregon, and Portland 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: Dryer vent cleaning is generally not a licensed trade in Oregon and has a low barrier to entry, though a local business license may be required to operate. If work extends into vent installation or alterations, additional contractor or mechanical rules may apply. A NISCR certificate is a professional credential, not a government license; always verify current local requirements in your Oregon area.
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.
