A duplex house layout where two units are attached next to each other. Also called twin homes, a standard duplex looks aesthetically like a single-family home evenly split in the middle, with separate entrances and inhabited by different owners. These multi-family properties are often mistaken as apartment buildings, with the difference being the size and the number of tenants living in the respective properties.

The following general contractors are some of the best duplex builders in the country. The companies were collated through extensive research that factored in several key criteria. Our editorial team considered company background, quality of portfolio, prestigious awards received, principal history, client reviews, and industry credentials.
