License vs Certification vs Training
Know What Your State Requires
Restoration work isn't one-size-fits-all across the country. Here's the difference between the three credentials, and where each state lands.
License
A state-issued legal credential to perform mold remediation work. Earned by passing a state exam plus meeting education or documented-experience requirements. States that license: Florida, Louisiana, New York, Texas, Washington DC.
Certification
Third-party proof that you're trained to do the work correctly. Voluntary in most states, required for registration in others. Certification states: Illinois (third-party cert + registration), Virginia (cert, not a license). IRI offers restoration certification.
Training
The education that prepares you to pass a state exam, earn a certification, and do the work correctly in the field. Where there's no requirement (like Tennessee and most states), training still gives you the edge that untrained competitors don't have.
License States
States That Require a Mold License
Florida
Requires a mold remediator license (Fla. Stat. 468.8413) to do remediation for compensation. Earn it by passing the state exam plus a 2-year degree with 30 science hours and 1 year experience, or a high school diploma plus 4 years documented field experience. There is no separate "worker training certificate" — the license itself is the credential. IRI training gives you the restoration knowledge to pass the exam and do the work right.
Requires a mold remediation contractor license for work over $7,500, issued by the State Licensing Board for Contractors. The license is held by the contractor, not the worker — workers and technicians do not need a license, but the contractor must complete 24 hours of board-approved mold remediation training and pass the exam. IRI's Mold Specialist course is board-approved and counts toward that 24-hour requirement.
It is unlawful to engage in a mold remediation project without a New York mold remediation license. Requires approved training courses and state licensing.
The Illinois Mold Remediation Registration Act requires mold remediation services to register with the state and provide evidence of active third-party certification and proof of financial responsibility. IRI's mold certification helps demonstrate that competency.
Tennessee does not regulate mold remediation — there is no state license, certification, or background check requirement. In most states, you can legally perform the work without training. That's exactly why training and certification still matter: they prove you know how to do the work right, and they give you the edge that untrained competitors don't have.

In most states, water, fire, and mold restoration work is not required by law to be trained or certified — licensed contractors can legally perform the work without it. But that's exactly why disaster recovery and restoration training matters. Your state license proves you can do the work; real, industry-recognized training proves you know how to do it right. When customers compare restoration companies, seeing that training gives you the edge that untrained competitors don't have.
Insurance pays for covered losses under the policy — it can't deny a covered claim just because the contractor isn't certified in restoration. Certification is voluntary, not a legal requirement. But there's an important distinction: work done by an unlicensed contractor, or faulty workmanship, can be excluded from coverage. That's why disaster recovery and restoration training matters — it shows you're taking the extra step to protect the customer, and that your company cares about restoring their property to pre-existing conditions.
No. Training schools and certification bodies — IRI, IICRC, ACAC, RIA, and others — do not issue licenses. A license is a legal credential that only a state government can grant, and only the state can say when one is required. What schools issue is training and certification: proof that you've learned how to do the work. An ID card or certificate from any school is not a license. If someone asks you for a "mold license," they're usually asking for your state's credential — or simply that you're trained and certified to do the work right. IRI gives you that training and certification, and we'll help you understand what your state requires.
