New York Rules On Mold

Who May Do Mold Work

New York licenses mold assessors, mold remediation contractors and mold abatement workers under Article 32 of the state Labor Law. The rules apply to mold jobs larger than 10 square feet. Some owners who do the work on their own homes are exempt.

The same person may not do both the assessment and the remediation on the same property. The assessor writes the plan, a separate licensed contractor does the work, and the assessor checks the result. You can check a license with the Department of Labor’s search for licensed mold contractors.
