Do I need a special permit to build in a flood zone in unincorporated Franklin County?

Yes. Section 6.5-81 requires anyone developing wholly or partly inside a mapped flood hazard area to apply to the Floodplain Administrator, and often the building official as well, and to obtain the required permit before work begins. This applies even to structures exempt from the Florida Building Code, like farm buildings and temporary construction sheds.

How long is a Franklin County floodplain development permit good for?

A floodplain development permit becomes invalid if the authorized work does not begin within 180 days of issuance, or if it is suspended or abandoned for 180 days after starting, under § 6.5-85. The Floodplain Administrator can grant extensions of up to 180 days at a time if the applicant shows justifiable cause in writing.

Who is the Floodplain Administrator in Franklin County?

The county's zoning administrator serves as the Floodplain Administrator under § 6.5-51 and may delegate duties to other staff. That office reviews applications, issues floodplain development permits, requires additional engineering data when needed, and can suspend or revoke a permit issued on incorrect or incomplete information.
