Licensing
Do you need a license in Knoxville?
Licensing for chimney sweep work is set at the state and local level in Tennessee, and Knoxville 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 Tennessee, though operating a business typically requires a local business license and some cities or counties may have registration requirements. If chimney work expands into masonry repair, relining, or other structural work, Tennessee contractor licensing can apply once a project reaches the $25,000 threshold. Your NISCR certificate is a professional credential, not a government license. Always verify current local and state requirements before performing regulated work.
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.
