New York State Mold Law Article 32: Licenses, Duties, and Penalties

New York’s Mold Law, codified at Article 32 of the Labor Law, requires anyone performing mold assessment, remediation, or abatement on an area larger than ten square feet to hold a license issued by the state Department of Labor.¹ The same law forces a clean separation between the company that inspects a property and the company that cleans it up, sets minimum work standards for both, and backs the whole scheme with fines up to $10,000 and license revocation.

When the Law Applies

Article 32 kicks in on any “project” involving mold assessment, remediation, or abatement where the affected area exceeds ten square feet. That’s roughly a three-by-three-foot patch. Anything smaller sits outside the licensing rules, and routine cleaning and construction or demolition work performed for reasons unrelated to mold removal are also excluded.²

The statute uses a narrow definition of mold. It covers indoor multi-cellular fungi capable of producing toxins that cause pulmonary, respiratory, neurological, or other serious illness, as defined by the EPA, CDC, NIH, or similar agencies.² Cosmetic mildew isn’t the target; health-threatening mold is.

One boundary catches people off guard. Article 32 remediation does not include fixing the moisture source. Repairing a leaking pipe, waterproofing a foundation, or replacing a roof requires a different type of contractor. The mold licensee handles the mold; someone else handles why it grew.²

The Three Licenses

Article 32 creates three distinct licenses, and confusing them is a common compliance mistake.

A mold assessment license covers contractors who inspect a property, identify mold, evaluate the conditions promoting it, and write a remediation plan. Initial fees run $150 to $300.
A mold remediation license covers contractors who remove contaminated materials, clean affected areas, and carry out the plan. Initial fees run $500 to $1,000.
A mold abatement license covers the individual workers who physically perform the hands-on removal, cleaning, and containment. Initial fees run $50 to $100.

Every license is issued by the Commissioner of Labor. Performing any of these activities without the correct license, or even advertising yourself as able to perform them, is illegal.¹ A copy of the valid assessment or remediation license must be posted at the work site for the duration of every project.²

Licensed architects, engineers, and other design professionals authorized under Title 8 of the Education Law can perform inspection, assessment, remediation, and abatement tasks within their scope of practice without a separate Article 32 license. The exemption does not extend to unlicensed people working under a design professional’s supervision on tasks outside that scope.²

The Assessor and Remediator Cannot Be the Same Company

This is the provision that trips up the most people. The same company cannot perform both the mold assessment and the mold remediation on the same property. The law also prohibits any person from holding an ownership interest in both the assessment licensee and the remediation licensee working on the same job.³

The reason is straightforward. If the company evaluating the mold is also being paid to remove it, they have every incentive to inflate the scope. Article 32 breaks that incentive by requiring two separate licensees on every project. Any contractor offering to assess and remediate as a package deal is violating the law.

What Must Be in the Assessment Plan

A licensed assessor does more than eyeball the walls. After inspecting, the assessor must write a project-specific mold remediation plan and give it to the client before any remediation begins. The plan has to cover the location and scope of the contamination, the estimated quantities of material to be cleaned or removed, the remediation methods for each affected area, the personal protective equipment the remediation contractor must supply, and the clearance criteria that will be used to measure success. It also has to address how occupants of an occupied building will be notified, an estimated cost and timeline, and, where identifiable, the underlying moisture source together with a recommendation for the type of contractor who can fix it.³

The assessor must also give a written report to every client for whom assessment services are performed. If the plan calls for a disinfectant, biocide, or antimicrobial coating, the product has to be EPA-registered for the intended use and applied per the manufacturer’s instructions.²

What the Remediation Contractor Must Do

The remediation contractor takes the assessment plan and builds a project-specific work plan on top of it. The work plan must fulfill every requirement in the assessor’s plan and add detailed instructions or standard operating procedures for how the work will be performed.⁴

Where the assessment plan requires PPE, the remediation contractor supplies it to every worker who will disturb or remove mold. Containment barriers have to prevent spores from spreading to the rest of the building under normal conditions, and warning signs must be posted at every accessible entrance to the work area.⁴

How to Get and Keep a License

The baseline requirements apply to all three licenses. Every applicant must be at least 18 years old and complete a commissioner-approved training course that covers proper use and care of personal protective equipment.²

Assessment and remediation contractors carry an additional obligation: at least $50,000 in liability insurance covering claims arising from their licensed activities, along with workers’ compensation coverage where required. Individual abatement workers do not need to carry their own liability insurance.²

Each license is valid for two years. Renewal costs the same as the initial fee and requires a commissioner-approved continuing education course on current assessment and remediation standards.⁵ Skip the continuing education and you cannot renew, which ends your ability to work legally.

Penalties and Enforcement

The Department of Labor enforces Article 32, and the penalties escalate fast. A first violation can bring a fine of up to $2,000. Each subsequent violation can draw up to $10,000.⁶

Fines are not the only exposure. The Commissioner can suspend or revoke a license entirely. Grounds include a felony conviction related to mold work, deceit or misrepresentation in obtaining the license, submitting false documents, defrauding the public, and incompetence or gross negligence in performing assessment or remediation.²

Before suspending, revoking, or fining a licensee, the Department must give at least ten days’ written notice of a hearing, and the licensee can respond in person or through an attorney. One exception matters: the Commissioner can order the immediate cessation of unlicensed activity without prior notice or hearing. Operating without a license carries no procedural cushion.²

Anyone hit with a suspension, revocation, fine, or license denial can appeal through an Article 78 proceeding in court.²

What Property Owners Have to Do

Property owners are not licensed under Article 32, but the law shapes what they must do. First, hire licensed professionals. Using an unlicensed contractor creates liability and can force work to be redone. Second, keep every document the process generates: assessment reports, remediation plans, work plans, and clearance results. Because assessment and remediation must be done by separate licensees, expect paperwork from at least two different companies on every project.

Verify contractor insurance before work starts. Both assessment and remediation licensees are required to carry at least $50,000 in liability coverage, and asking for a certificate is a basic step many owners skip.² Standard homeowners policies often cap mold coverage at low sub-limits, and insurers may ask for proof that any work was done by licensed professionals in compliance with Article 32 before approving a claim.

An Extra Layer in New York City

Owners in New York City face a second set of rules on top of Article 32. NYC Local Law 55 of 2018 treats indoor mold as an allergen hazard and imposes obligations on owners of multiple dwellings, meaning buildings with three or more residential units.⁷

Under Local Law 55, owners must investigate for indoor allergen hazards, including mold, at least once a year in all occupied units and common areas. Additional investigations are required when the owner knows or should know about conditions likely to produce mold, when a tenant complains, or when the city issues a violation.⁷

The city classifies visible mold violations by square footage within a single room. Less than 10 square feet is a non-hazardous violation. Between 10 and 30 square feet is hazardous. Anything 30 square feet or more is immediately hazardous, with a 21-day correction deadline after the notice of violation is served.⁷

These city categories sit alongside state licensing. A NYC building owner with a mold problem above ten square feet must comply with both regimes: hire Article 32-licensed professionals for assessment and remediation, and also meet the city’s investigation, notification, and correction deadlines.
