A triplex is similar to a duplex or fourplex, but instead of the property being a two- or four-unit structure, a triplex is a three-unit multifamily structure with one owner.
While a triplex consists of three individual dwelling units combined into one building, the individual units will typically share one or two common walls. Each unit of a triplex is self-sufficient, meaning each dwelling space has its own respective kitchen, bathroom(s), living room, a separate door to the outside, and its own address or unit number.
Some triplexes are constructed as triplex, and others might have originally been built as a large, single-family home that was later divided into three separate dwellings.
A triplex is sold as one building, and the owner usually rents out all the units or lives in one unit and rents the other two. In some cases, a triplex owner can live in one unit and have family members live in the other units. Typically, however, a triplex is purchased for investment purposes: to earn rent money
