Post-Remediation Clearance Testing in Riverview, FL

My Riverview home flooded from the Alafia. Do I really need clearance before rebuilding?

In most flood cases it is worth it. When Helene came through in 2024, homes on Parkway Circle along the Alafia River took up to five feet of water, and residents said it rose higher than they had seen before. Remediation after that kind of flooding involves long runs of cut drywall, wet insulation and framing that has to dry completely. EPA says to assume mold growth when materials stay wet beyond 24 to 48 hours, so the question isn't whether mold was present but whether the crew got all of it and the framing dried. A clearance visit answers that while the wall cavities are still open. For rebuilding, Hillsborough County Development Services covers unincorporated Riverview, and county guidance says structural repairs in a Special Flood Hazard Area need a permit.

Our house is only about 15 years old. Why would it fail?

The age of the house doesn't decide it. Riverview's median build year is 2006, and only about 7 percent of homes predate 1980, but newer slab homes still get AC condensate overflows, supply-line leaks and roof leaks after storms. Failures usually trace back to a source nobody repaired, framing closed up too early, or fine debris left after demolition. About 8 percent of local homes are mobile homes, and for those the assessor should look at the subfloor and under the home, not just the interior walls.

Who should hire the assessor, me or the remediation company?

You should. Florida's s. 468.8419 bars a remediator from assessing a structure it remediated within 12 months, and the law also forbids an assessor from taking a job where the fee or the findings depend on the outcome. Hiring the assessor directly keeps the report working for you. Ask what the clearance will measure, such as visual inspection, moisture readings and surface or air samples against an outdoor baseline, since there are no federal numeric limits for mold. Then check the assessor's license on DBPR's online licensee search.
