Mold licensing in Arizona
We did not find an Arizona license specific to mold inspectors or remediators. The state health department's mold guidance says larger jobs may call for a professional or a contractor holding a state license. Arizona's contractor law covers people who are paid to alter or repair buildings, so repairs after mold may need a contractor with an Arizona contractor license. Ask for credentials in writing, and check the Registrar of Contractors site for current requirements.
