Which term refers to residential buildings designed to house multiple families?

The term that refers to residential buildings designed to house multiple families is "multifamily housing." This type of housing includes structures such as apartment buildings, duplexes, triplexes, and condominiums, which are specifically designed to accommodate more than one household. Multifamily housing provides various benefits, such as shared amenities and potentially lower living costs due to economies of scale.

Single-family homes are designed for one family and do not cater to multiple families living in one structure. Commercial properties pertain to buildings used for business activities rather than residential purposes. Agricultural land is dedicated to farming and agricultural practices and is not intended for residential living. Thus, multifamily housing is the correct term to describe residential buildings for multiple families.
