Is a Mold Inspector Required to Be Licensed? It Depends Entirely on Your State

There is no federal mold inspector license, and no single national answer to “is a mold inspector required to be licensed” — the EPA does not license or certify mold professionals, and regulation of mold inspection and remediation is left almost entirely to individual states. In most of the country, technically, anyone can call themselves a mold inspector without holding any state-issued credential. A minority of states have closed that gap with their own licensing programs, and the requirements differ significantly from state to state.

States That Currently License Mold Inspectors/Assessors

Based on current state programs, the following states require a state-issued license or registration for at least some mold inspection or remediation work:

Florida — The Department of Business and Professional Regulation (DBPR) licenses Mold Assessors and Mold Remediators separately under Florida Statutes Chapter 468, Part XVI, for any job over 10 square feet. Licensees complete approved training, pass an exam, undergo a background check, and carry at least $1 million in liability insurance. The same company generally cannot both assess and remediate the same property within 12 months.

Texas — The Texas Department of Licensing and Regulation (TDLR) licenses mold assessment technicians, mold assessment consultants, and mold assessment/remediation companies, plus mold remediation contractors, under the Texas Mold Assessment and Remediation Rules. Licensing requires training, an exam, and a background check; the same prohibition against one entity both assessing and remediating a project applies.

Louisiana — The State Licensing Board for Contractors licenses mold remediation specialists, who must complete training covering both assessment and remediation plus instruction on Louisiana’s Unfair Trade Practices and Consumer Protection Law.

New York — The Department of Labor licenses Mold Assessors, Mold Remediation Contractors, Mold Supervisors, and Abatement Workers under Labor Law Article 32 (the 2015 “Mold Law,” fully effective 2016). Home inspectors whose reports include mold assessment must also hold a Mold Assessor license. The assessor and remediator cannot be the same entity on the same project.

A smaller number of other states regulate parts of the mold industry more narrowly — for example, some require specific accreditation (such as ACAC certification) for assessors, or set minimum work standards without a full licensing regime. Requirements change as state legislatures act, so always confirm current status directly with your state’s licensing agency rather than relying on any single list — including this one — as permanently current.

States With No Mold Inspector License

Most US states, including New Jersey and Maryland (which briefly licensed mold remediation contractors from 2008 to 2019 before that program was terminated), currently have no state-specific mold inspector or remediator license. In these states, anyone can legally offer mold inspection or remediation services without a mold-specific credential — general contractor licensing or home improvement contractor registration may still apply to the work broadly, but there’s no dedicated mold license to verify.

How to Vet a Mold Inspector Where No License Exists

Where there’s no state license to check, the credential that actually means something is independent, verifiable industry certification — not a company’s own marketing claims:

IICRC (Institute of Inspection, Cleaning and Restoration Certification) — AMRT (Applied Microbial Remediation Technician) is the primary mould-specific credential. Verify any individual’s or company’s current status directly at iicrc.org; credentials are individually registered and searchable.
CIH (Certified Industrial Hygienist) — the highest independent credential for health-hazard assessment; relevant for the assessment side specifically.
CIEC (Council-certified Indoor Environmental Consultant) — an IAQ-specific certification.
ACAC (American Council for Accredited Certification) — the accrediting body several states (including Florida’s and historically Maryland’s programs) reference for mold-specific credentials.

Regardless of state licensing status, the single most important structural safeguard is using an assessor who is independent of the remediation company — someone with no financial stake in inflating (or downplaying) the scope of the remediation job that follows. This is required by law in licensed states like Florida, Texas, and New York; in unlicensed states, it’s a practice homeowners have to insist on themselves.

Why the Assessor/Remediator Separation Matters More Than the License Itself

Even in states with mold-specific licensing, the license alone doesn’t guarantee good practice — the more meaningful protection is the licensed states’ shared rule that the same company can’t both find the problem and get paid to fix it. In unlicensed states, replicate that protection yourself: hire an independent assessor first, get a written protocol, then separately hire a remediation contractor to work from that protocol, and have the same independent assessor (not the remediator) perform clearance testing afterward.

Frequently Asked Questions

Is there a national mold inspector certification?

No single mandatory national license exists. IICRC and ACAC are widely recognized voluntary industry certifications used across states, but neither is a government license in states without their own licensing program.

Does the EPA license mold inspectors?

No. The EPA publishes guidance on mold (including recommended practices), but it does not license or certify mold inspectors or remediators. Licensing, where it exists, is a state function.

What states currently require mold assessor licensing?

Florida, Texas, Louisiana, and New York are the states with the most established, currently active mold-specific licensing programs as of this writing. A few other states regulate narrower aspects of the industry. Confirm current requirements with your specific state’s licensing or consumer affairs agency, since this changes as legislatures act.

Did Maryland ever require mold licensing?

Yes — Maryland’s Mold Remediation Services Act (2008) required licensing through the Maryland Home Improvement Commission, but the program was terminated on July 1, 2019, and Maryland currently has no mold-specific state license.

If my state doesn’t license mold inspectors, does that mean the industry is unregulated?

Not entirely. General consumer protection law, contractor registration requirements, and standard fraud/negligence law still apply. What’s missing in unlicensed states is a mold-specific credentialing and enforcement regime.

How do I check if a mold inspector’s license is real?

In licensed states, use the state licensing board’s public lookup tool (for example, TDLR’s or DBPR’s license search, or NY DOL’s licensed contractor search). For IICRC credentials in any state, search directly at iicrc.org rather than accepting a certificate shown to you in person.

Should I still hire a licensed mold inspector if my state doesn’t require it?

Yes, where practical. Choosing an IICRC-certified, independent assessor gives you a documented, verifiable standard of training even where the law doesn’t require it — and it’s the best available substitute for state oversight.
