Licensed Mold Testing & Inspection in New York City
What This Inspection Covers
Our licensed mold assessors perform comprehensive mold assessments following NYS Article 32 (12 NYCRR Part 820) standards. Inspection includes visual assessment of all accessible areas, air sampling (spore trap method), surface sampling where visible growth is observed, and outdoor baseline samples for comparison. Assessment results are documented in a written report that meets all NYS DOL requirements.
Who Needs This & When
You need a professional mold assessment if you are: purchasing a property (pre-purchase due diligence); experiencing unexplained respiratory symptoms, chronic sinusitis, or asthma flare-ups; responding to an HPD or DOH mold violation notice; preparing for mold remediation (an independent assessment from a separate company is required by NYC Local Law 55); dealing with water damage or flooding; or managing a rental building subject to NYC Local Law 55 (§27-2056.11).
Inspector Credentials
All mold inspectors on 123inspections hold a NYS DOL Mold Assessor License (Article 32 of the New York State Labor Law, 12 NYCRR Part 820). Under New York State law, a licensed assessor must be a separate individual from any remediation contractor — we are an inspection-only platform.

Frequently Asked Questions
Does a mold inspector in NYC need a license?
Yes. Under New York State Article 32 (Labor Law §§ 930-939, 12 NYCRR Part 820), anyone performing a mold assessment in New York State for compensation must hold a NYS DOL Mold Assessor License. Unlicensed individuals cannot legally perform paid mold assessments. All inspectors on 123inspections are licensed — you can verify their license number on the NYS DOL website.
What is the difference between a mold inspector and a mold remediator?
A mold inspector (assessor) evaluates whether mold is present and writes a report. A mold remediator removes the mold. Under NYC Local Law 55 and NYS Article 32, the same individual or company cannot perform both the assessment and the remediation for the same property. This separation protects you from conflicts of interest — a remediator who also assesses has a financial incentive to find problems. 123inspections is inspection-only.
What NYC law requires mold inspections in rental buildings?
NYC Local Law 55 of 2018 (Administrative Code §27-2056.11) requires building owners to investigate and remediate mold conditions in dwelling units. For any mold remediation covering more than 10 square feet, the building owner must hire a NYS DOL Licensed Mold Assessor to conduct a post-remediation assessment to confirm remediation was successful. Additionally, before any remediation, an assessment report must be prepared by a licensed assessor separate from the remediator.
How much does a mold inspection cost in NYC?
A professional mold inspection in New York City typically costs $299–$499 for residential properties, depending on size. Larger properties, commercial spaces, or multi-unit buildings cost more. The price includes air sampling, laboratory analysis at an accredited lab, and a written assessment report. See our pricing page for exact ranges by property size.
What does an outdoor baseline sample mean in a mold report?
An outdoor baseline sample measures the types and concentrations of mold spores naturally present in the outdoor air at the time of inspection. This is the reference point against which indoor air samples are compared. Per IICRC S520 standards, indoor mold conditions are assessed relative to outdoor levels — not against fixed numeric thresholds. This comparison is required for a scientifically valid mold assessment.
