Licensing
Do you need a license in Denver?
Licensing for chimney sweep work is set at the state and local level in Colorado, and Denver 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: Chimney sweeping is generally not a separately licensed trade in Colorado, though some municipalities require a local business license or registration, and any structural or venting repairs may fall under building codes. Verify current requirements with your city or county before working. A NISCR certificate is a professional credential that documents your training and builds customer trust, 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.
