In New York, mold assessment on projects larger than ten square feet requires a license from NYS DOL under Article 32 of the Labor Law — a Mold Assessment Contractor license for the business, and individual Mold Assessor licenses for the people doing the work. The state also prohibits the same individual from performing both the assessment and the remediation on the same property.
