How Much Does a Modular Fourplex Cost in BC in 2026?

A fourplex gives your family four homes on one lot, and building it modular can make the project faster and more predictable. But the first thing everyone wants to know is the cost. This guide gives real 2026 ranges for BC, explains what drives the number, and shows how to get a quote for your lot.

The short answer

A full fourplex project in Vancouver in 2026, including the lot, commonly runs from about $3.0 million to $5.2 million, depending on where the lot is, the size of the homes, and the finishes (Source: MultiLiving cost analysis, 2026). A modular fourplex sits in a similar range, because the biggest cost, the land, is the same however you build.

That is a big number, but remember it buys four separate homes. Split across four households, the cost per home is far lower than buying four detached houses.

Where the money goes

It helps to split the budget into four parts:

• The lot: usually 35 to 50 percent of the total, and the same for modular or traditional.
• Building the homes: the next largest part, and where modular can save a little.
• Design, permits, and fees: a meaningful slice that does not change much with modular.
• Site work and finishing: varies by lot, and partly affected by the method.

Only the building part shifts much with modular, which is why a modular fourplex costs in a similar range to a traditional one.

Why the lot drives the total

In Greater Vancouver, a buildable lot in East Vancouver can cost roughly $1.5 to $1.9 million, and comparable west-side lots more (Source: MultiLiving cost analysis, 2026). Because the lot is fixed no matter how you build, it sets the floor for the whole project.

This is also the strongest argument for a fourplex. Four homes share one lot, so the land cost per household is the lowest of the common multiplex types. A prefab duplex or triplex spreads that cost across fewer homes.

What modular does to the building cost

Published figures for completed modular homes in BC often begin around $250 to $300 per square foot for the building itself, before land and site costs (Source: BC prefab market figures, 2026). A fourplex can differ from a single home because of shared walls and several kitchens and bathrooms. Treat per-square-foot numbers as a rough guide only, not a quote.

The real value of modular here is efficiency and speed. Building all four homes in a factory while your lot is prepared keeps a big project on a tighter, more predictable schedule, which also lowers financing costs.

What this comes down to

• A Vancouver fourplex in 2026 commonly costs $3.0 to $5.2 million including the lot, modular or traditional.
• The lot is the biggest cost and is the same either way.
• Four homes share one lot, so the land cost per household is the lowest of the common types.
• Modular's building cost begins around $250 to $300 per square foot, but only a quote is accurate.

Frequently asked questions

How much does a modular fourplex cost in BC?

Including the lot, a Vancouver fourplex commonly runs $3.0 to $5.2 million in 2026. Modular sits in a similar range because the land is the biggest cost and does not change with the method.

Is a modular fourplex cheaper than a traditional one?

Usually a little on the building, and often on financing because it finishes faster. Total costs are close because land and finishes dominate. Compare quotes to see your number.

What is the cost per square foot for a modular fourplex?

Completed modular homes in BC often start around $250 to $300 per square foot for the building, before land and site costs. A fourplex can differ due to shared walls and extra kitchens.

How much of the cost is the land?

Usually 35 to 50 percent in Greater Vancouver. A buildable East Vancouver lot can run $1.5 to $1.9 million, with west-side lots higher.

Can four families split the cost of a fourplex?

Yes, that is a common approach. Four households share one lot, which lowers each family's share of the land, the biggest cost. How ownership is structured is something to plan with professionals.

What extra costs should I budget for?

Design and permits, site preparation, connecting services, delivery and crane access, and finishing. A clear written quote should list what is included and excluded.

Does a fourplex earn rental income?

It can. An owner can live in one home and rent the other three, or the whole building can be family-occupied. You decide how it is used.

How many homes can I build on my lot?

BC rules allow several homes on many single-family lots, often up to six, and more in parts of Vancouver. The exact number depends on your lot, which a builder confirms early.

Is financing harder for a modular fourplex?

It used to be, because the factory stage did not fit standard loan draws. In 2026 CMHC expanded support for modular multi-unit building, which helped. See financing a prefab multiplex.
