Hurricane Season is Here. Is Your Mold License Ready?

Six months of hurricane season started June 1 - and in New York, that's not just a weather story. It's a compliance story.

CDC assessments show that nearly half (46%) of homes develop visible mold growth following hurricane flooding.

NOAA is forecasting a below-normal 2026 Atlantic hurricane season, with 8–14 named storms and 3–6 hurricanes predicted through November 30. But as NOAA's National Weather Service Director Ken Graham put it: "It only takes one storm to make for a very bad season." Tropical systems bring rain, flooding, and roof damage - and all of that sets up ideal conditions for mold growth in New York buildings within 24 to 48 hours of water intrusion.

When that work starts rolling in, you need to be ready to take it.

What New York Law Requires

The New York State Department of Labor’s Mold Program enforces Article 32 of the New York State Labor Law and establishes licensing requirements and minimum work standards for professionals engaged in mold assessment and remediation. The law is direct: contractors will not be allowed to advertise or perform covered mold work without the required license. 

And don’t forget - mold assessment and mold remediation are two separate licensed activities; with Article 32 prohibiting the same firm from performing both the assessment and remediation on the same property. 

In New York City, the requirements layer further. Under NYC Local Law 55, when there is more than 10 square feet of mold in a building with 10 or more units, landlords must hire NYS Department of Labor-licensed mold assessors and remediators. Post-storm demand in multifamily housing will likely trigger exactly that threshold repeatedly. 

The Penalties for Getting It Wrong

Unlicensed mold work in New York is not a gray area. Since Article 32 took effect in 2016, NYSDOL has issued thousands of violations to contractors who ignored licensing requirements. If you're involved in mold removal without the right certification, you could face NYSDOL enforcement action, fines, and a bar from performing mold work until licensed.

In New York City, the enforcement stakes for building owners compound the problem for any contractor whose client gets cited. Mold violations are classified as Class C immediately hazardous violations, which must be corrected within 21 days of service. For buildings with more than 5 units, Class C violations carry civil penalties enforced through Housing Court. A building owner who hired an unlicensed contractor and still has an open violation is facing that penalty. So is the contractor who created the liability. 

The post-storm window is when NYSDOL and HPD complaints spike. Don't be the contractor who gets caught in it. 

Hurricane Season Is the Busiest Mold Season

Post-storm mold calls don't wait for you to get credentialed. Building owners need licensed professionals fast, and property managers in NYC are under specific legal obligations to use them. If your license is expired, or you've been doing assessments or remediation work without one -  now is the time to fix that.
