Can You Build a Prefab Fourplex on a Standard Vancouver Lot?

A standard Vancouver lot used to hold one house. Today, in many cases, it can hold four homes. If your family is thinking about a prefab fourplex, the first question is whether your lot allows it. This guide explains what the rules permit and how to check.

The short answer

In many cases, yes. BC's small-scale housing rules, often called Bill 44, require many municipalities to allow three to six homes on lots that used to permit only a single house (Source: Government of BC, small-scale multi-unit housing legislation). Vancouver's own policy allows even more homes on suitable lots. A fourplex is a common result because the layout and economics work well on a standard lot.

What a standard Vancouver lot looks like

A typical Vancouver lot is about 33 feet wide and 122 feet deep. That size is well suited to a fourplex, usually arranged as two homes reached from the street and two reached from a rear lane, with two homes on each of two floors. The homes are mirrored around shared walls so the building reads as one house, not an apartment block. We describe this in more detail on our prefab fourplex page.

What decides how many homes you can build

The exact number depends on a few things about your specific lot:

• Its size, since larger lots can hold more homes.
• Its location, since lots near frequent transit may allow more.
• Your municipality's current zoning, which sets the details within the provincial minimums.

Because the rules vary by lot and city, a builder or the city checks your specific property early in the process, so you know your options before you commit.

Why prefab suits a fourplex

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

What it costs

A full fourplex project in Vancouver in 2026, including the lot, commonly runs from about $3.0 million to $5.2 million (Source: MultiLiving cost analysis, 2026), with prefab in a similar range. Because four homes share one lot, the land cost per household is the lowest of the common types. Our cost guide has the full breakdown.

What this comes down to

• Many standard Vancouver lots can now hold a fourplex under BC's small-scale housing rules.
• A typical 33 by 122 foot lot suits a fourplex with two street homes and two lane homes.
• The exact number of homes depends on your lot's size, location, and zoning.
• Prefab suits a fourplex because it keeps a complex build on schedule.

Frequently asked questions

Can I build a fourplex on a single-family lot in Vancouver?

In many cases, yes. BC rules now allow several homes on many single-family lots, and Vancouver's policy supports multiplexes. A fourplex is a common outcome on a standard lot.

How big does my lot need to be for a fourplex?

A typical 33 by 122 foot Vancouver lot suits a fourplex well. Smaller lots may allow fewer homes, and larger lots may allow more. A builder confirms this for your lot.

How many homes does Bill 44 allow?

It requires many municipalities to allow three to six homes on former single-family lots, depending on lot size and location. Vancouver allows more on suitable lots.

Do I need to rezone my lot?

Often not, because the provincial rules make multiplexes a permitted use on many lots. Your municipality's current zoning sets the details. A builder or the city can confirm.

Where do the four homes enter?

Usually two homes enter from the street and two from a rear lane, with two homes per floor. This keeps the building looking like one house rather than a block of doors.

Is a prefab fourplex allowed the same as a traditional one?

Yes. Prefab methods are permitted like any other build. The method does not change what your lot allows; that is set by size, location, and zoning.

How much does a prefab fourplex cost?

Including the lot, a Vancouver fourplex commonly runs $3.0 to $5.2 million in 2026, with prefab in a similar range. See our cost guide for detail.

Can my whole family live in the fourplex?

Yes. Many families use all four homes themselves, or live in some and rent others. Each home is private with its own entrance, so everyone keeps their independence.

How long does it take to build?

The factory stage is fast, but the full project takes many months once you include design and permits. See our timeline guide.
