Prefab fourplex: four homes, one lot

A prefab fourplex puts four private homes on one lot, built mostly in a factory. It offers the most homes and the greatest shared use of one property, which makes the land cost per household the lowest of the common multiplex types. Here is how it works and who it suits.

A fourplex is four homes on one lot, built as a single building. In a prefab fourplex, the homes are made as factory modules or panels and then set and finished on your land. It is the largest multiplex type most families consider, and it makes the fullest use of one lot.

How a prefab fourplex is arranged

A typical fourplex has two homes reached from the street and two reached from a rear lane, with two homes on each of two floors. The units are mirrored around shared walls so the building reads as one cohesive structure. Each of the four homes is private, with its own entrance, kitchen, and bathrooms. A well designed fourplex looks like a large modern house, not an apartment block.

Who a prefab fourplex suits

  • Larger families who want three or four households on one property.
  • An owner who wants to live in one home and rent three for income.
  • A group of relatives pooling resources to afford a better neighbourhood together.

If you need fewer homes, a triplex or duplex may fit better and cost less to build.

Why prefab for a fourplex

A fourplex is the most complex of the common types, so building off-site gives the biggest time benefit. All four homes can be made in the factory while your lot is prepared, then set in a short window. That keeps a big project on a predictable schedule with fewer weather delays. See prefab vs traditional and the timeline for how the stages fit together.

In many cases yes. BC rules now allow three to six homes on many single-family lots, and Vancouver's own policy allows even more on suitable lots. A fourplex is a common outcome because the layout and economics work well on a standard lot. The exact number depends on your lot's size and location, which a builder will confirm early so you know what your property allows.
