Tennessee Rules On Mold

Who May Do Mold Work

Tennessee has no stand alone mold inspector license. Instead, the Board for Licensing Contractors has a Mold Remediation classification on its contractor license. Tennessee requires a contractor license for jobs of $25,000 or more, so a large mold job should go to a company licensed in that classification.

State law does not bar one company from both inspecting and remediating the same job, so hiring an independent inspector is your own choice. You can check a contractor’s license and classification on the state’s online license lookup.
