Garages

Attached Garages
A garage attached to a residential structure or in an enclosed area below an elevated building may have the garage floor slab below the Base Flood Elevation (BFE). Because such a garage is an enclosed area below the BFE, openings are required either in the exterior walls of the garage or in the garage doors themselves.

Below-grade Parking Garages
Below grade parking garages are only allowed in non-residential buildings in Zones A1-30, AE, AH, and AO and must be dry floodproofed. The construction of below grade parking garages is prohibited beneath residential buildings. Below-grade parking garages are prohibited beneath all residential and non-residential buildings in V Zones.

Detached Garages
Small detached garages for residential uses may qualify as Accessory Structures under the NFIP.
