Florida Mold Law
What Chapter 468, Part XVI of the Florida Statutes Actually Says
Florida is one of a small number of states requiring professional licensing for mold-related services. Chapter 468, Part XVI of the Florida Statutes governs this field. The Florida Department of Business and Professional Regulation (DBPR) administers the licensing program and maintains a public database where anyone can verify that an individual performing mold work holds an active license.
The two license types
- Mold Assessor (MRSA) — A licensed mold assessor performs visual inspection, sampling, documentation of findings, and written reports. The MRSA prefix followed by a number identifies a licensed assessor. J. Cory King holds Florida Mold Assessor License MRSA2944.
- Mold Remediator (MRSR) — A licensed mold remediator performs the physical process of containing, removing, and cleaning mold-contaminated materials.
Anyone performing mold-related services on areas exceeding 10 square feet must hold an active DBPR license. Below that threshold, licensed professionals are not legally required (though their use is still strongly advisable).
The conflict-of-interest prohibition — Florida Statute 468.8419
Florida Statute §468.8419 prohibits the same company from performing both mold assessment and mold remediation on the same property within a 12-month period. The criminal penalties are significant: a second-degree misdemeanor for a first violation, a first-degree misdemeanor for a second, and a third-degree felony for a third or subsequent violation.
The legal logic is direct. A company that profits from remediation has a financial incentive to find more mold, overstate the scope, or recommend unnecessary work. By prohibiting the same entity from assessing and remediating the same property, the law creates a structural separation that gives the assessment its integrity.
What this means in practice: If a company offers to both assess your mold problem and remediate it on the same property, that arrangement violates Florida law. An independent mold assessor — with an MRSA license and no remediation affiliation — provides an unbiased assessment because they have no financial stake in the remediation outcome. This is not marketing; it is a legal and scientific principle.
Licensing requirements for Florida mold assessors
- Educational qualification: two-year degree in a qualifying field plus one year of documented field experience, or high school diploma plus four years of documented mold assessment field experience
- Documented training in water intrusion, mold, and respiratory protection
- Passage of a DBPR-approved examination
- $1,000,000 in general liability and errors & omissions insurance for assessment work
- 14 hours of state-approved continuing education per biennial renewal period
- Biennial license renewal by July 31 of each even year
DBPR license vs. certification — what the difference is
A DBPR mold assessor license (MRSA) is a statutory license backed by criminal penalties for violations and publicly verifiable through the state database. Industry certifications from organizations like ACAC (American Council for Accredited Certification), IICRC, and AIHA are based on demonstrated competency standards from independent scientific and professional bodies. Some certifications are proprietary — issued by franchise organizations or private companies, requiring only completion of a course offered by that same organization. These proprietary certifications are not independently verifiable and do not carry the same professional accountability as a state license or independent body credential.
How to verify a Florida mold assessor license
Go to MyFloridaLicense.com and use the License Search function. Search by license number (e.g., MRSA2944) or by name. An active license shows the licensee name, license number, type, status, and expiration date. Any licensed assessor should provide their license number without hesitation. Unwillingness to do so is a red flag.
Frequently Asked Questions
Can a home inspector perform a mold assessment in Florida?
A home inspector licensed under Florida Statute Chapter 468, Part XV can visually note apparent mold growth as part of a general home inspection. However, a home inspection license does not authorize mold assessments as defined under Part XVI. Systematic mold assessment — moisture mapping, sampling, laboratory coordination, and written assessment reports — requires a Florida Mold Assessor (MRSA) license.
Is it legal for a company to offer both free assessment and paid remediation?
The arrangement may violate Statute 468.8419. If the company performing the free assessment is the same legal entity as the company performing the subsequent remediation, this is prohibited by the statute regardless of whether the assessment was free or paid. The consumer's interest in independent assessment is also not served by an assessment provided by a company with a financial relationship to the remediator.
What are the penalties for unlicensed mold work in Florida?
Performing mold-related services without a license on areas exceeding 10 square feet is unlicensed activity subject to DBPR investigation and penalties. Under Statute 468.8419, a company performing both assessment and remediation on the same property within 12 months faces: second-degree misdemeanor (first violation), first-degree misdemeanor (second), and third-degree felony (third or subsequent). Work by unlicensed contractors may also be rejected by insurance carriers and given reduced evidentiary weight in legal proceedings.
Why does ACAC CIE certification matter in addition to the state license?
The Florida MRSA license establishes that an assessor has met the state's minimum education, experience, and examination requirements. The ACAC Certified Indoor Environmentalist (CIE) credential establishes broader competency in indoor environmental assessment including IAQ, building science, industrial hygiene principles, and sampling methodology — based on demonstrated expertise, not just course completion. The combination of an active MRSA license and an ACAC CIE credential represents both regulatory compliance and demonstrated professional competence.
