8plex

An eightplex is a residential building that contains eight separate housing units within a single structure. It is part of a family of multi-family housing terms that describe unit count, such as duplex (two), triplex (three), fourplex (four), and sixplex (six). Eightplexes are common in many North American cities and suburbs, where they offer medium-density housing capable of fitting more units on a single lot while preserving a neighborhood scale.

Configurations vary: two four-unit blocks, a three-story building with four apartments per floor, or a two-story complex with four stacked units. Units may be rental apartments or individually owned condominiums or townhomes. Shared walls and common mechanical systems are typical, reducing per-unit construction costs but increasing the need for coordinated maintenance. On-site parking, landscaping, and sometimes communal amenities are common considerations.

Zoning determines whether eightplexes are permitted, usually under multi-family or higher-density residential districts. Eightplexes can offer higher density than single-family homes while maintaining a human-scale footprint, which appeals to developers and investors seeking efficient land use. Market dynamics—rents, purchase prices, financing, and property taxes—affect ownership models and capitalization.

The term eightplex is mainly used by real estate professionals, property managers, and builders. While not a formal standardized typology, it is widely understood in the industry as a specific unit-count configuration within multifamily housing.
