What characterizes a Two-Family Dwelling Unit?

• A. A building that consists solely of two dwelling units with independent cooking and bathroom facilities.
• B. A building that consists solely of one dwelling unit with independent cooking and bathroom facilities.
• C. A building that consists of three or more dwelling units.
• D. A building that has one dwelling unit and no independent facilities.

Answer: (A)

Two-family dwelling units are buildings designed to house two separate living spaces, with each unit having its own kitchen and its own bathroom facilities. This self-contained setup for both units is what distinguishes a two-family dwelling from other types.

So, the choice that describes a building with exactly two dwelling units and independent cooking and bathroom facilities is correct. If a building has only one dwelling unit with independent facilities, that’s a single-family dwelling. If there are three or more dwelling units, that’s not two-family. And a unit without independent facilities wouldn’t meet the typical dwelling-unit definition in this code. The independent facilities matter because they define separate, self-contained living spaces within the same structure.
