MRSR

Definition

MRSR (Mold Remediation Service Registration) is a state-issued license required in Florida for businesses that perform mold remediation work on residential or commercial properties. Administered by the Florida Department of Business and Professional Regulation (DBPR), MRSR registration mandates that contractors meet minimum insurance requirements ($1 million general liability), demonstrate financial responsibility, and employ at least one MRSA (Mold Remediation Service Assessor) on staff. The license must be renewed every two years with updated insurance certificates and continuing education completion.

Why It Matters

Florida is one of few states with comprehensive mold licensing laws, enacted after widespread fraud and incompetent remediation following the 2004 hurricane season. For homeowners, the MRSR system provides consumer protection: it creates a verified registry of legitimate contractors, establishes minimum competency standards, and enables enforcement actions against fraudulent or negligent operators. Unlicensed mold remediation in Florida is a criminal offense, and homeowners who hire unlicensed contractors may face insurance claim denials and legal liability. Always verify MRSR status through the DBPR website before hiring—active licenses display the contractor's insurance coverage, address, and any disciplinary history.

How It's Used in Mold Work

Contractors must display their MRSR registration number on all advertising, proposals, and contracts. The license covers the business entity, but actual remediation must be supervised by an MRSA-licensed individual who has passed the state examination on remediation protocols. Florida law also mandates conflict-of-interest separation: a company with MRSA (assessment) and MRSR (remediation) licenses cannot perform both services on the same property—homeowners must use separate companies for testing and cleanup. When obtaining quotes, ask contractors for their MRSR number and verify it's active and complaint-free on the DBPR public search portal. Insurance adjusters typically require MRSR documentation before approving mold claim payments.
