Louisiana Rules On Mold

Who May Do Mold Work

Louisiana requires a mold remediation license from the State Licensing Board for Contractors when a mold remediation job is worth more than $7,500. The license holder must complete board approved training in mold remediation and assessment. The state does not issue a separate license for mold inspectors.

Louisiana law bars a licensed mold remediation contractor from doing both the mold assessment and the remediation on the same property. It also bars owning a share of both the company that assesses and the company that remediates the same property. You can look up any contractor by name or license number in the board’s contractor search.
