The Licensing Requirement
New York State Article 32 of the Labor Law (§§ 930-939, implemented as 12 NYCRR Part 820) created a mandatory licensing regime for mold assessment and remediation work. Effective 2016, anyone performing paid mold assessments in New York State must hold a NYS DOL Mold Assessor License.
This is not a certification or a trade organization membership. It is a state license issued by the New York State Department of Labor. The law is explicit: no person may conduct a mold assessment for compensation without this license.
Two License Types Under Article 32
Article 32 created two categories of licensed professionals:
Mold Assessor (MA): Performs visual inspections, collects air and surface samples, interprets results, and prepares assessment reports. This is the license required for the type of work 123inspections' inspectors perform.
Mold Remediator (MR): Performs the actual physical removal and treatment of mold-affected materials. Under Article 32, the assessor and remediator for the same job must be different licensees.
Some individuals hold both licenses — but they still cannot serve as both assessor and remediator on the same project.
License Requirements
To obtain a NYS DOL Mold Assessor License, an applicant must:
1. Meet the education requirement: Hold a high school diploma or GED minimum; many assessors hold degrees in environmental science, industrial hygiene, engineering, or related fields
2. Complete NYS DOL-approved training: A minimum training course from a DOL-approved provider covering assessment methodology, sampling protocols, report writing, and regulatory requirements
3. Pass the NYS DOL Mold Assessor examination
4. Submit an application to the NYS Department of Labor with proof of training and examination
5. Pay the application fee
6. Renew every two years with continuing education requirements
How to Verify a License
The NYS Department of Labor maintains a public license lookup tool at labor.ny.gov. You can search by name or license number to confirm:
Always verify before hiring. An inspector who cannot provide their license number — or whose license doesn't appear in the DOL database — cannot legally perform a paid mold assessment in New York State.
At 123inspections, every mold assessor's license number is visible in their profile, and we verify all licenses are current before onboarding. You can independently verify any inspector's license using the NYS DOL lookup.
What If Someone Assesses Without a License?
Performing a paid mold assessment without a NYS DOL Mold Assessor License is a violation of NYS Labor Law. The assessment report they produce is not legally valid for:
Hiring an unlicensed assessor doesn't just create a compliance risk — it means you may need to hire a licensed assessor again to produce valid documentation.
The Mold Assessor vs. Industrial Hygienist Distinction
Some environmental professionals hold certifications from trade organizations (CIH — Certified Industrial Hygienist, CIEC — Council-certified Indoor Environments Consultant) that cover indoor air quality broadly. These certifications do not substitute for a NYS DOL Mold Assessor License for work in New York State. The NYS license is the legal requirement; the trade certifications are professional qualifications that may complement (but do not replace) it.
Assessor vs. Remediator: The Separation Requirement
A critical provision of Article 32 that both consumers and contractors frequently misunderstand: the mold assessor and the mold remediator for the same project must be different licensed individuals and different companies.
This applies even if both individuals hold both license types. A company that both assesses and then remediates the same mold problem is in violation of this requirement — regardless of whether both operations are technically licensed.
The purpose is to prevent the conflict of interest that arises when the company that identifies and quantifies the problem is also the company that profits from its remediation.
