Lab pathway

Air sampling and third-party analysis

Verify before operating

New York's broad statutory definition likely covers sample collection — no confirmed collection-only exemption exists.

  • 01NY Labor Law § 930 defines mold assessment broadly as any action "designed to discover mold" — air sample collection almost certainly falls within this definition.
  • 02No DOL opinion or regulation explicitly exempts a "sample collector only" who sends cassettes to a third-party lab — the collection step likely requires a NY DOL Mold Assessor license.
  • 03Sending samples to an AIHA-accredited lab does not replace NY DOL licensure for the person performing the collection.
  • 04Minimum credential: NY DOL Mold Assessor license — 32-hour approved course, $0 individual fee (or $150 contractor registration), $50,000 GL insurance.
  • 05Penalties: up to $2,000 for a first violation; up to $10,000 for subsequent violations.
  • 06Recommendation: Consult a New York environmental attorney before beginning air quality sampling operations in New York.

This summary addresses the spore-trap collection, accredited third-party lab analysis, and report-rendering model for New York. Verify the current interpretation with the responsible state authority or qualified counsel.

Before accepting work

Additional notes

  • 01New York requires complete attendance for all DOL-approved training courses — missing any session invalidates the certificate of completion.
  • 02The assessor and remediator on any single project must be separate licensed individuals or entities.
