Prefab multiplex cost in BC, explained

A prefab multiplex in Greater Vancouver costs in a similar range to a traditional one, because the lot is the biggest cost and prefab does not change the land price. Here is how the costs add up in 2026, and how to get a real number for your plan.

The figures below are general 2026 ranges for guidance only, not quotes. Costs move with the market and vary a lot by lot, design, and finishes. The only accurate number is a builder quote for your specific project.

The short answer

A full fourplex project in Vancouver in 2026, including the lot, commonly lands between about $3.0 million and $5.2 million, depending on where the lot is, the size of the homes, and the finishes. A prefab fourplex sits in a similar range, because the biggest single cost, the land, is the same however you build. Prefab can trim the building portion and shorten the schedule, which helps, but it does not turn an expensive market into a cheap one.

Where the money goes

It helps to split a multiplex budget into four parts. Only one of them changes much with prefab.

Cost partRough share of totalDoes prefab change it?
The lot (land)35 to 50 percentNo, same either way
Building the homesThe next largest partYes, can be modestly lower
Design, permits, and feesA meaningful sliceMostly no

Shares based on published Vancouver fourplex cost data, 2026. See the linked cost breakdown below for detail.

Land: the biggest number

In Greater Vancouver, the lot is usually 35 to 50 percent of the whole project. A buildable lot in East Vancouver can cost roughly $1.5 to $1.9 million, and comparable west-side lots more. Because this price is fixed no matter how you build, it is the main reason prefab and traditional multiplexes cost about the same overall. It is also why putting two, three, or four family homes on one lot makes so much sense: each home carries a smaller share of that land cost.

Building cost: where prefab helps

The building itself is where the prefab method can save money. Factory work uses labour efficiently, wastes less material, and avoids weather delays. Published figures for completed modular homes in BC often begin around $250 to $300 per square foot for the building, before land and site costs. A multiplex can differ from a single house because of shared walls and extra kitchens and bathrooms. Treat per-square-foot numbers as a rough guide only.

Common questions

Questions people ask

For a full fourplex project in Vancouver in 2026, total costs including the lot commonly run from about $3.0 million to $5.2 million, based on published market data. Prefab does not change the land price, which is the largest part of that number, so a prefab multiplex costs in a similar range to a traditional one. The building portion can be a little lower with prefab. The only accurate figure is a builder quote for your exact lot and plan.
In Greater Vancouver, land typically makes up 35 to 50 percent of a multiplex project's total cost. A buildable lot in East Vancouver can run roughly $1.5 to $1.9 million, and west-side lots more. Because the lot price is fixed no matter how you build, the choice between prefab and traditional affects only part of the remaining cost. This is why sharing one lot among several family homes is such a big part of the appeal.
It can, mostly by using factory labour efficiently, wasting less material, and shortening the schedule so you pay less in financing. But the saving is modest and varies by project, because land, design, permits, and finishes cost about the same either way. Treat prefab as a way to build faster and more predictably, with a possible cost saving, rather than a guaranteed discount.
Published figures for completed modular homes in BC often start around $250 to $300 per square foot for the building itself, before land and site costs. Multiplex projects can differ because of shared walls, stairs, and multiple kitchens and bathrooms. Use per-square-foot numbers only as a rough guide. Your builder's quote, which accounts for your design and site, is the number to plan around.
