What is a "Duplex" in the context of residential units?

In the context of residential units, a duplex refers to a dwelling that is specifically designed to house two separate living units. Each unit typically has its own entrance, and they are often configured either vertically, with one unit on top of the other, or horizontally, with each unit side by side. This arrangement allows for two families to reside in a single building while having distinct living spaces.

The concept of a duplex is significant in urban planning and residential development, as it provides a way to increase housing density without sacrificing the feel of a single-family home. It accommodates two households and can be a more economical option for both developers and residents, as costs can be shared. Understanding the definition of a duplex is vital for identifying various housing types and their roles in community development.
