What Is a Multiplex? A Buyer's Guide to Duplexes, Triplexes & Fourplexes in BC

What exactly is a multiplex?

A multiplex is a residential building with two to six units on a single lot. That's it. No lobby. No elevator. No shared hallways. Each unit has its own front door, its own kitchen, its own address. You walk in from the street like you would a house — because for all practical purposes, it is one.

The terminology breaks down by unit count:

• Duplex — two units, typically side-by-side or stacked
• Triplex — three units arranged across one, two, or three storeys
• Fourplex — four units, often in a two-over-two layout
• Sixplex — six units, the upper end of what most municipalities allow under multiplex zoning

Think of a multiplex as the middle child between a detached house and an apartment building. Smaller than a tower. More independent than a condo. You get the density cities want without losing the street-level feel that people actually enjoy living in. These buildings look like houses. They sit on residential streets. Your neighbours probably won't even notice the difference.

Why multiplexes are suddenly everywhere in BC

For decades, most residential land in BC was zoned exclusively for single-family homes. One house, one lot, no exceptions. That changed in November 2023 when the provincial government passed Bill 44, which required municipalities across the province to allow multiplexes on lots previously reserved for single-family housing. Overnight, the rules changed for every city and town in BC.

Vancouver moved even faster. The City approved its own multiplex zoning framework in September 2023, two months before the province acted. The response has been significant: according to VanPlex data, 498 multiplex applications had been filed in Vancouver as of January 2026. That's not a trickle. That's a new housing type establishing itself in real time.

The numbers tell a clear story about demand. CMHC data shows that Vancouver's missing middle housing starts — the category that includes multiplexes — dropped 56% from 2,300 units in 2018 to just 1,002 in 2024. Years of restrictive zoning choked supply. But the rebound is already underway: 785 new missing middle starts were recorded in the first half of 2025 alone, putting the full year on track to exceed pre-decline levels.

The bottom line: multiplexes aren't a trend. They're the result of a permanent policy shift. The land was always there. The zoning finally caught up.

How a multiplex differs from a condo or townhome

On paper, a multiplex unit and a condo might seem similar. Both give you a home in a multi-unit building. The difference is in how you own it and how much control you have.

Many multiplex units are sold as freehold. You own the land under your unit. No strata corporation. No monthly strata fees that climb every year. No strata council voting on whether you can install a heat pump or paint your door red. You make the decisions.

Townhomes offer more space than condos, sure. But most townhome developments are strata-titled, which means you're still paying fees and following rules set by the collective. Multiplex freehold ownership removes that layer entirely.

Size matters too. A typical multiplex unit runs between 1,000 and 1,500 square feet — comparable to a small house. Each unit has its own private entrance from the street or a short walkway. You're not sharing a lobby or riding an elevator with thirty other households. The experience feels residential, not institutional.

One important caveat: not all multiplex units are freehold. Some developers use strata titles, especially for larger projects. Always check the title type before you buy. The ownership structure changes everything about your ongoing costs and autonomy.

Who buys multiplexes?

The short answer: people who want more than a condo but can't swing a $2.2 million detached house in Vancouver. That's a lot of people.

First-time buyers are the most obvious group. A multiplex unit priced between $700K and $1.1M gives you freehold ownership, a front door, outdoor space, and a real neighbourhood. For someone who thought homeownership in Vancouver meant a 500 sq ft condo or a two-hour commute, that's a different equation entirely.

Families wanting multi-generational living are another growing segment. Buy two units in a fourplex and your parents live next door. Close enough to share dinners. Separate enough to have your own space. This arrangement is common in many cultures and multiplexes make it financially and logistically simple.

Then there are buyers who want rental income. Purchase a duplex, live in one unit, rent the other. That rental income offsets your mortgage — sometimes by $2,000 to $3,000 per month. It turns homeownership from a pure expense into something that partially pays for itself.

And frankly, some buyers just hate strata. They've lived in condos. They've dealt with special assessments, pet restrictions, and renovation approval processes that take six months. A freehold multiplex unit means nobody else gets a vote on how you live.

What to watch out for

Multiplexes are a strong option for the right buyer, but they come with considerations that condos and detached homes don't. Go in with open eyes.

Limited resale history. Most multiplexes in BC are brand new construction. There's no ten-year price trend to study. No track record of how the building ages. You're buying into a housing type that's proven elsewhere — Toronto, Montreal, Portland have had multiplexes for decades — but is new to this market. That means less comparable sales data for your appraiser to work with, which can complicate mortgage approvals.

Financing can be tricky. For duplexes, most lenders treat the purchase like a standard residential mortgage. Once you get to three or more units, some lenders reclassify the property as commercial or require larger down payments. Shop around. Talk to a mortgage broker who has handled multiplex transactions specifically. The difference between lenders can be significant.

Construction quality varies. The multiplex building boom has attracted experienced developers and newcomers alike. Some builders have decades of multi-family experience. Others are building their first project. Always get an independent home inspection, even on new construction. Pay attention to soundproofing between units — it's the number one complaint in shared-wall housing and the area where builders most often cut corners.

Check the title structure. As mentioned above, not all multiplex units are freehold. Some are strata-titled, which means strata fees, strata rules, and a strata corporation making collective decisions. Neither structure is inherently better, but they're fundamentally different ownership experiences. Know which one you're buying before you sign.

Key takeaways

• A multiplex is 2–6 units on one lot, each with a private entrance — like a house, but with neighbours who share walls instead of a fence.
• BC's Bill 44 and Vancouver's 2023 zoning changes unlocked multiplex construction province-wide. This is a permanent policy shift, not a pilot program.
• Freehold multiplex units mean no strata fees and full control over your property — but always verify the title type before purchasing.
• Buyers range from first-timers to multi-generational families to people seeking rental income from adjacent units.
• Do your homework on financing (especially for 3+ units), get an independent inspection, and check soundproofing between units.

Frequently asked questions

How much does a multiplex cost in Vancouver?

Individual multiplex units in Vancouver typically range from $700,000 to $1.1 million depending on size, location, and number of bedrooms. Whole-building purchases (all units) can range from $1.8M to $3.5M. Prices in Surrey, Burnaby, and other Metro Vancouver cities tend to run 10–25% lower than the City of Vancouver.

Do multiplexes have strata fees?

It depends on the title structure. Freehold multiplex units have zero strata fees — you own the land and are responsible for your own maintenance. Strata-titled multiplex units do have monthly fees, typically $150–$350, covering shared costs like exterior maintenance and insurance. Always confirm which structure applies before making an offer.

Can I rent out units in my multiplex?

Yes, if you own a freehold unit there are no strata rental restrictions. You can rent it out as a long-term rental or live in one unit and rent the others. For strata-titled multiplexes, rental rules are set by the strata corporation. Check BC's Strata Property Act and your specific strata bylaws for any limitations on rental use.
