Flood Zone Door FAQs

What are the door requirements for VE flood zones in Monroe County?

VE zones in Monroe County require breakaway walls or flood openings below the Base Flood Elevation. Doors in these areas must be designed to fail safely or be flood-resistant. Living space doors above BFE must meet HVHZ impact requirements. Garage doors may require breakaway panels.

Can I have an enclosed space below BFE in a VE zone?

Enclosed spaces below BFE in VE zones must use breakaway walls designed to collapse under flood loads without damaging the elevated structure. Doors in these enclosures should be breakaway or flood-resistant rated. These spaces can only be used for parking, storage, or building access.

Do entry doors above BFE still need HVHZ ratings in flood zones?

Yes, all exterior doors above the Base Flood Elevation in Monroe County must meet HVHZ impact and pressure requirements regardless of flood zone designation. This includes entry doors, sliding glass doors, and French doors. The doors need valid NOA or Florida Product Approval.

What is the difference between AE and VE zone door requirements?

AE zones experience stillwater flooding while VE zones face wave action. VE zones require breakaway construction below BFE and have stricter elevation requirements. Door specifications vary: AE zone doors below BFE need flood openings while VE zone doors must be breakaway rated or above BFE.
