Florida Mold Remediation Law: Statute 468 Part XVI — What Miami Homeowners Must Know
By DRY MASTERS Technical Team · Updated September 2026 · 7 min read
Florida is one of the few states with specific licensing requirements for mold professionals — and the law has a critical restriction most homeowners don’t know about.
Under Florida Statute 468 Part XVI, the same company that assesses your mold problem cannot legally be the one that remediates it. This conflict-of-interest protection exists specifically to protect you. Understanding this law could save you from being overcharged or having unnecessary work performed.
⚖️ Florida Statute 468 Part XVI — The Core Rule
§468.8419(3): “A person may not perform mold assessment and mold remediation on the same structure or project.”
This means the company that tells you how much mold you have and writes the remediation protocol cannot be the company that performs the remediation and bills for it. The two roles must be separate entities.
Effective date: July 1, 2011. Still in full force as of 2026.
The Two Regulated Roles
🔍 Mold Assessor (Licensed MRSA or MRSE)
- Conducts air sampling and surface sampling
- Uses moisture meters and thermal cameras
- Identifies mold types present
- Writes the remediation protocol that tells remediators what to do
- Performs post-remediation clearance testing
- CANNOT perform the actual remediation
🧹 Mold Remediator (Licensed MRRSA)
- Follows the protocol written by the assessor
- Performs physical removal of contaminated materials
- Sets up containment and HEPA filtration
- Applies biocides to hard surfaces
- CANNOT write their own protocol for what work to do
- Cannot perform post-remediation clearance testing

Before this law, a common scenario was: Company A comes to your home, “discovers” you have extensive mold, writes a remediation protocol that maximizes billable work, and then performs all that work themselves. There was no independent check on whether the work described was actually necessary, whether the scope was accurate, or whether it was actually completed.
Florida Statute 468 Part XVI breaks this conflict of interest. Now:
- An independent licensed assessor evaluates your home and writes the protocol
- A separate licensed remediator performs only what the protocol specifies
- The same independent assessor returns to verify the remediation was successful
This three-party process — assessor → remediator → assessor for clearance — is the legally required structure in Florida for any mold remediation project.
⚠️ Red Flag: Companies Offering “One-Stop” Mold Assessment + Remediation
If a company offers to assess your mold AND remediate it, they are either: (1) misrepresenting how the process works, (2) doing the work without proper licensing, or (3) using a subsidiary company that legally qualifies as separate under the statute. Ask for both license numbers and confirm they are separate entities with the Florida DBPR.
Licensing Requirements Under Florida Statute 468
Florida requires licensing for anyone performing mold assessment or remediation work on a residential or commercial property. The requirements, administered by the Florida Department of Business and Professional Regulation (DBPR):
Mold Remediator License (MRRSA — Mold Related Services Remediator)
- Must pass a Florida-approved mold remediator exam
- Minimum 30 hours of continuing education every 2 years
- Must maintain liability and workers’ compensation insurance
- Cannot perform or commission their own assessments on projects they remediate
Exemptions Under the Statute
Not all mold work requires a licensed professional. Florida law exempts mold remediation work that:
- Involves an area of 10 square feet or less (about a 3×3 foot area)
- Is performed by the property owner on their own primary residence (single-family home only)
- Is part of normal housekeeping and cleaning
Any mold area larger than 10 square feet, or any commercial property, requires licensed professionals for both assessment and remediation.
How to Verify a Mold Contractor’s License in Florida
- Go to myfloridalicense.com
- Click “Verify a License”
- Search by license number or contractor name
- Confirm the license type is “Mold Related Services” and the status is “Active”
DRY MASTERS carries all required Florida mold-related services licenses. We work with a network of independent licensed mold assessors for the assessment and clearance phases of every project, maintaining the required separation under Statute 468.
What This Means for Your Insurance Claim
If you’re filing a homeowner’s insurance claim for mold remediation, your adjuster will typically require documentation that the work was performed by licensed professionals following a licensed assessor’s protocol. Work performed by an unlicensed company may not be covered. More importantly, if a claim dispute reaches litigation, the lack of licensing can significantly undermine your position.
DRY MASTERS documents every project with the assessor’s protocol, the remediator’s work log, and the post-remediation clearance report — the complete paper trail your insurance company and any attorney would need.
Summary: The 3 Things Every Miami Homeowner Needs to Know
- The assessor and remediator must be different companies — this is Florida law, not optional
- Both must hold Florida licenses — verify at myfloridalicense.com before any work starts
- Any area larger than 10 sq ft requires licensed professionals — DIY on larger areas exposes you to health risk, liability, and potential insurance coverage issues
