Why New York’s Mold Law Is Being Misinterpreted — and How Homeowners Can Protect Themselves
Based on an episode of the Daniel Stih Podcast
When a homeowner sent me a screenshot from a major mold remediation company in New York, something immediately stood out. Their bid was close to $200,000.
The justification for their approach came from their interpretation of New York Labor Law Article 32, which governs mold inspection and remediation. Their email stated that the goal of remediation is not to create a mold-free building and that, according to state guidelines, remediation is considered successful when the work area is “clean, dry, and free of visible mold.” Sounds reasonable. Sounds official. It’s also wrong.
This kind of misinterpretation is exactly why homeowners across the country believe mold remediation is subjective, inconsistent, and impossible to trust.
In this article, I’ll break down:
- Why “visible mold only” is a dangerous and misleading standard
- What New York law actually says
- How contractors twist the language to lower expectations
- The real standard of care every homeowner should demand
And most importantly, why mold is not everywhere, and why treating it that way sets homeowners up for failure.
The Myth: “You Can’t Remove Mold — It’s Everywhere”
This line shows up in marketing, inspection reports, contractor emails, and even casual conversations:
“Mold is everywhere. You can’t get rid of it.”
That’s true. It is not the same thing as there is mold growth inside a home. Remediation is about removing actual growth, not every spore in the universe. Outdoors, mold belongs. Indoors, it does not.
New York’s legal definition of mold is, “…multicellular fungi growth capable of producing toxins and causing illness after minimal exposure.”
If we substitute the legal definition of mold in the statement, “Mold is everywhere. You can’t get rid of it, we get the contractor saying, “Fungi growth capable of producing toxins and causing illness after minimal exposure…is everywhere. You cannot get rid of it.”
Vague language becomes misinformation and marketing ammo for remediation companies.
What the Law Says and Why the Law is Misinterpreted.
Article 32 was written to establish minimum work standards for inspectors and remediators. Minimum. Not ideal. Not best practice. Not complete remediation. The law requires a mold assessor to create a remediation plan, a remediator to follow that plan, and post-remediation clearance conducted by the assessor. It does not say that visible mold is the end goal. It does not say that hidden mold doesn’t matter. It does not define clearance by air samples.
The law references “visible mold” in minimum compliance language. some companies therefore claim, “As long as visible mold is gone, remediation is successful.” That’s like saying, “If you can’t see termites, your house is termite-free.” Everyone knows better.
The Real Standard for “Actual Mold Growth”
The respected industry standard for mold remediation, ANSI/IICRC S520, uses a different definition. Mold that is actively growing indoors must be removed. Not just “visible” mold, not “some” molds, not “most” mold - all actual mold growth. Actual mold growth is not acceptable. That is the definition inspectors and remediators should be using.
When a contractor says, “You can’t make a mold-free environment,” they are confusing airborne spores with actual growth. The goal isn’t sterility. The goal is eliminating actual indoor mold growth. There is no scientific basis for leaving any amount of mold growth in a house after remediation simply because it can’t be seen.
Why Contractors Lean on “Visible Mold”
It’s simple: Visible mold is easy to remove; Hidden mold is not. If clearance only requires removing what can be seen, a contractor can avoid opening walls, avoid handling hidden water damage, avoid a deeper inspection, and avoid liability. They can finish faster, charge less up front, and pass clearance testing every time. That benefits companies. It does not benefit homeowners. It explains why people spend thousands on remediation only to stay sick, as actual mold growth remains sealed behind drywall, under flooring, or inside framing.
Air Samples Don’t Prove Success
Air sampling is the most misused test in mold remediation. Air samples show one moment in time. If an air scrubber is running, and it often is, the results are meaningless. And air scrubber is as a big air filter. The air should be clean. Mold growth can still be present with a “good” air test Good air samples do not mean the mold is gone. They mean the air was good at the moment of testing.
Mold Laws Aren’t the Solution
Licensing sounds like protection. Licensing however, simply means the contractor took a clas, paid a fee, and got a certificate. A certificate is not the same thing as accredited third-party “certification”. With a certificate there is no guarantee of competence. When laws are unclear, contractors start improvising. When contractors improvise, homeowners lose.
Mold Is Not Everywhere
Contractors who say: “mold is everywhere” are using that phrase as justification, a built-in excuse to do work. The S520 standard eliminates that confusion by defining mold properly as: “Actual mold growth indoors.” You can detect it. You can identify it. You can locate it. You can remove it. You can prevent it from returning.
What Homeowners Should Ask Remediation Companies
Here are the questions that cut through the fog:
“Will you guarantee removal of actual mold growth — not just visible mold?”
If they won’t say yes, stop.
“Will the assessor confirm, in writing, that actual mold growth is gone?”
If they tell you air samples are enough, they’re wrong.
“How will you locate hidden mold?”
If the plan doesn’t include invasive inspection, it’s incomplete.
“What standard are you following?”
If the answer isn’t S520, that’s a red flag.
“Will you guarantee the mold won’t return from the same cause?”
If not, why are you paying them?
Final Thought
Mold remediation isn’t about paperwork and laws. It isn’t about visible mold. It’s about people, their homes, their health, and their future. When a remediation company tells homeowners that mold is everywhere and can’t be eliminated, what they’re really saying is “We don’t want to be responsible for results.” If you need help understanding a remediation bid, a mold plan, or confusing legal language, reach out. I can help you think clearly, avoid misinformation, and protect yourself from a system built on ambiguity.
