The framework.
New York's Labor Law Article 32, codified at 12 NYCRR Part 945, establishes a state-wide licensing regime for mold inspection, assessment and remediation. The law took effect in 2016 after several years of phased implementation.
Three license types exist:
- Mold Assessor. Inspects, samples, identifies the scope of mold problems and writes the remediation work plan.
- Mold Remediation Contractor. Performs the remediation under the assessor's work plan.
- Mold Abatement Worker / Supervisor. Individual-level licenses for workers and supervisors on remediation projects.
The 10-square-foot threshold.
Article 32 applies to mold projects involving more than 10 square feet of mold. Below that threshold, the licensing requirement does not attach — though the underlying moisture problem still needs to be addressed.
For most multi-family and commercial projects, this means Article 32 is in play. For a small bathroom-ceiling growth in a single-family home, it often is not.
The separation requirement.
This is the part that matters most operationally. Article 32 requires separation between the assessor and the remediation contractor on the same project. A firm holding both licenses cannot perform both roles on a single engagement.
Why this matters: the assessor sets the scope and signs the post-remediation clearance. If the same firm performs the remediation, they're effectively grading their own work. The state's judgment is that the conflict is significant enough to require structural separation.
How firms with both licenses operate.
Many established firms (Envirex included) hold both licenses. On any given project, the firm runs one role and brings in a separately-credentialed firm for the other. The separation is documented in writing and observed throughout the project.
This is not a paperwork formality — the independent assessor's clearance has independent legal standing, and the documentation must support that independence.
What a work plan covers.
An Article 32 work plan, written by the assessor, defines:
- Scope of work (what's being remediated, in what areas).
- Containment requirements (class and configuration).
- Personal protective equipment requirements.
- Engineering controls (HEPA negative-air sizing, dehumidification).
- Post-remediation clearance criteria — what conditions must be met to pass.
The remediation contractor works to the plan; the assessor signs off (or doesn't) at clearance.
What happens if separation is violated.
The work product is not Article 32-compliant. For HPD or DOH violation closure, that's a problem — the documentation will not satisfy regulators. For insurance claims, it can affect coverage. For litigation, it weakens evidentiary value.
The practical lesson: when hiring a mold remediation contractor, the first question is "who's the assessor, and is the separation documented in writing?" If the answer is unclear, the project isn't being run to the standard.
Verify a license.
NYS Department of Labor maintains a public mold license search. Any assessor or contractor working in New York should be searchable there — and if they aren't, they shouldn't be on your project.
