Florida Rules On Mold

Who May Do Mold Work

Florida licenses both mold assessors and mold remediators through the Department of Business and Professional Regulation. The license covers mold work on areas larger than 10 square feet.

State law keeps the two jobs apart. A mold assessor may not remediate a building that the assessor or the assessor’s company assessed in the last 12 months, and a remediator may not assess a building it remediated in that time. To check a license, search the DBPR license lookup by name or license number before you sign anything.
