New York mold questions
For larger jobs, yes. The New York State Department of Labor defines a mold project as work on “areas greater than ten (10) square feet,” and says it is unlawful to “engage, advertise or hold themselves out as a mold assessor, remediation contractor, or abatement worker unless they have a valid mold license.” It notes “limited exceptions such as home or business owners performing work on their own properties.”

No. The Department of Labor’s rules include “prohibiting the performance of both the assessment and remediation on the same property by the same individual.”

Usually not. The Department of Labor says: “In most cases, air sampling and mold testing is unnecessary.” It also notes that “the mere presence of mold does not trigger any obligation to obtain an assessment or perform remediation.”
