An early apartment building.
This is an example of an early apartment building near Stearns' Quarry. Quite a number of similar buildings are scattered about the area. Multiple family housing buildings became popular (in the period known as the "flat craze") around 1881 -- right about the time Bridgeport began its biggest building boom. Bridgeport housing, in terms of the number of dwellings, is fairly evenly divided among the various building sizes -- single-family, four-family, etc. Only two-family/double-flats stand out as a leading type.
