NYS Article 32 vs Pennsylvania DEP. Mold inspection licensure differences explained

New York has had mandatory state licensure for mold assessors and remediators since 2018 under DOL Article 32. Pennsylvania has no equivalent state licensure. This guide explains the practical consequences for property owners and businesses operating in both states.

§01

NYS DOL Article 32 in plain English

Article 32 of the New York Labor Law (effective January 2018) created two distinct state-licensed roles for mold work: Mold Assessors (the testers) and Mold Remediation Contractors (the removers). The law mandates that these two roles be performed by different parties. A single firm cannot both assess and remediate. Mold Assessor licensure requires 40 hours of approved training + exam + continuing education + insurance + bond. Mold Remediation Contractor licensure has similar requirements. Both licenses are issued by the NYS Department of Labor.

§02

Why Article 32 separation matters

The separation-of-roles requirement directly addresses the conflict of interest that exists when a remediation contractor performs the assessment that determines whether remediation work is needed. A contractor who performs assessment has financial incentive to find more work; a contractor who performs remediation has financial incentive to maximize scope. NY's framework requires the assessor to be independent of the remediator. The assessor's report drives the scope, and a different (separately-retained) remediator performs the work.

§03

Pennsylvania has no equivalent. Practical consequences

Pennsylvania has no state-issued mold inspector or remediator licensure. Anyone in PA can call themselves a 'mold inspector' or 'mold remediator' without any specific credentialing requirement. This produces wide variance in quality: legitimate PA practitioners are credentialed through trade associations (NORMI, IICRC, AIHA, IAC2) and use AIHA-accredited labs; less-legitimate practitioners may perform visual-only assessments with no lab analysis or bundle assessment + remediation under the same firm without disclosure of the conflict of interest.

§04

What to ask when retaining a PA mold inspector

Without state licensure to filter on, PA property owners should ask: (1) Does the inspector use an independent AIHA-accredited laboratory for sample analysis? (2) Does the inspector perform remediation themselves, or do they refer to independent remediators? (3) What trade-association credentials does the inspector hold (NORMI Certified Mold Inspector, IICRC Certified Mold Remediation specialist, AIHA member)? (4) Will the inspector provide chain-of-custody documentation? (5) Does the inspector carry liability insurance specifically for environmental work?

§05

Cross-state work. Applying NY discipline in PA engagements

Environmental firms operating in both NY and PA typically apply NY's Article 32 discipline to their PA work as well. Even though PA doesn't require it. This means: independent of remediation, AIHA-accredited lab partnerships, chain-of-custody on every sample, written reports with regulatory benchmarks. PA property owners benefit from working with firms that apply NY-grade discipline regardless of where they're located.

FAQ

Related questions

Is a NY mold assessor license recognized in PA?

NY's Article 32 license is not formally required in PA, but it's a strong credential indicator. A NY-licensed mold assessor working in PA brings the discipline + training + standards required under Article 32. Even though PA wouldn't require those credentials on its own. Our work follows NY Article 32 discipline and applies the same discipline to our PA work.

What happens if a NY mold inspector remediates in NY?

Violation of Article 32. NY DOL can issue penalties + license suspension. More practically: any report produced by a firm that violates the separation requirement is potentially impeachable in litigation or regulatory action. Legitimate NY firms maintain strict separation of testing and remediation work. Many partner with separate remediation firms for follow-up work after their independent assessment.

Does PA plan to adopt licensure?

PA legislation has been discussed in some form periodically but no comprehensive mold licensure bill has been enacted as of 2026. Some PA municipalities have local registration requirements but no state-level mandatory licensure exists. Pennsylvania DEP regulates radon mitigators (Radon Mitigation Specialist certification) but not mold inspectors.
