Multi-family residence refers to a building with five or more dwelling units. Multi-family buildings typically have four stories or more above ground and may have one or more floors below ground. See Figure 1-1 for a representative multi-family building. The term includes condominium and apartment buildings in addition to congregate residences (e.g., nursing homes, assisted living facilities, dormitories, group homes, detoxification facilities, detention centers, sororities, and fraternities).

Prefabricated frame home that is transportable in one or more sections and can be placed on a permanent or temporary foundation (subject to federal and state standards).

For floodplain management purposes, “agricultural structures” are structures that are used exclusively for agricultural purposes or uses in connection with the production, harvesting, storage, raising, or drying of agricultural commodities and livestock. Some structures used for aquaculture are considered agricultural structures. Structures used for human habitation and those that are places of employment or entertainment, and structures with multiple or mixed purposes, do not satisfy the “exclusive use” requirement described below and are not agricultural structures. Structures that are not agricultural structures (or accessory structures, see Section 2.4) must be designed and constructed to meet or exceed the NFIP requirements for structures in SFHAs.
