Mold licensing in Maryland

Maryland does not have a state license or certification requirement for mold inspection, testing or removal. Maryland once required mold remediation contractors to hold a license through the Home Improvement Commission, but that law ended on July 1, 2019. Ask any mold company what training it has, such as voluntary IICRC certification, and get a written scope of work and proof of insurance. Check Maryland Department of Labor's site for current information.
