A two-unit home, also known as a DUPLEX, is a residential building that contains two separate living units. It is typically divided into two separate dwellings, each with its own entrance, kitchen, and bathroom. The two units are usually connected by a shared wall or floor, and may be owned by the same person or different people. Duplexes are often found in urban areas, where they provide an affordable housing option for people who want to live close to the city center.
