Half-Duplex vs Full Duplex: What's the Difference, and Which Should You Buy? (2026)

"Duplex" is one of those words that means different things depending on who's saying it — and in Vancouver listings you'll see both "half-duplex" and "full duplex." The difference matters, because it changes what you actually own and what you pay. Here's the plain-English version, so you know exactly what you're buying.

The simple definitions

A duplex is a single building divided into two separate homes. When people say half-duplex, they mean you're buying one of those two homes — your own half, privately owned. When people say full duplex, they mean the entire building, both homes, owned by one buyer.

For almost everyone shopping to live in their home, a half-duplex is what you want: you own your home, with your own front door, and you're not responsible for a second household's home. A full duplex is a much larger purchase and a different situation entirely.

How they differ for a buyer

• What you own — a half-duplex is one of two homes; a full duplex is the whole building (both homes).
• Price — a half-duplex costs roughly half of a full duplex, which makes it the realistic option for most families wanting to own and live in their home.
• Front doors and privacy — a half-duplex gives you your own entrance and your own space; you share one common wall with the home next door.
• Side-by-side vs up-and-down — half-duplexes come in two common shapes: side by side (sharing a vertical wall) or up and down (one home above the other). Side-by-side often feels more house-like.
• Strata or not — many newer half-duplexes are part of a small strata that handles shared insurance and any common elements; some are arranged differently. Always ask how a specific home is set up.

Which one is right for you

If you're buying a home to live in — including two generations of a family who each want their own space — a half-duplex is almost certainly what you're after. It's the affordable, practical way to own a brand-new home with a private entrance and more room than a condo.

A full duplex — owning the entire building — is a much bigger commitment and suits a very different buyer. In our view, unless you have a specific reason to own both homes, the half-duplex is the simpler, smarter choice for a family that just wants a great place to live.

What a half-duplex costs in Vancouver

Half-duplexes fall under the "attached home" category, whose benchmark price across Greater Vancouver was $1,043,400 in April 2026, down 5.1% year over year, per Greater Vancouver REALTORS. The same report showed a balanced market for attached homes, meaning more choice and negotiating room. Exact prices depend on size, neighbourhood, and how new the home is — a brand-new side-by-side half-duplex in a sought-after area sits at the higher end.

What to focus on when you tour

Once you know you're after a half-duplex, judge each home on what you'll feel daily: which way the windows face, how the layout flows, storage, outdoor space, parking, and how private it feels from the home next door. Side-by-side and up-and-down homes live quite differently, so tour both and see which suits you. Our compare tool helps you line them up.

Frequently asked questions

What's the difference between a half-duplex and a full duplex?

A full duplex is the entire building — both homes — owned by one buyer. A half-duplex is just one of those two homes, privately owned with its own front door. Most people buying a home to live in are buying a half-duplex.

Is a half-duplex cheaper than a full duplex?

Yes, considerably — a half-duplex is one of two homes, so it costs roughly half of the whole building. That's why the half-duplex is the realistic, common choice for families who want to own and live in their home.

Do I share anything with the other half of the duplex?

You share at least one common wall, and often a small strata arrangement that handles shared insurance and any common elements. You own your home and have your own entrance. Always ask how a specific home is set up.

What's the difference between side-by-side and up-and-down?

A side-by-side half-duplex shares a vertical wall with the home next door, so each home spans multiple floors — more house-like. An up-and-down has one home above the other. They live quite differently, so tour both before deciding.

Is a half-duplex the same as a townhouse?

They're similar but not identical. A half-duplex is one of two homes in a building; a townhouse is one of several (often more) in a row. Both give you a private entrance and more space than a condo. The feel and price can be comparable.

How much does a half-duplex cost in Vancouver?

Half-duplexes fall under attached homes, whose Metro Vancouver benchmark was about $1.04 million in April 2026. Exact prices depend on size, neighbourhood, and newness — a brand-new side-by-side home in a popular area sits at the higher end.

Does a half-duplex have a strata?

Many newer half-duplexes are part of a small strata that handles shared insurance and common elements; some are arranged differently. It's a normal, usually low-key part of ownership. Always ask what a specific home's setup and any fees are.

Should I buy a half-duplex or a townhouse?

Both are great ways to own a brand-new home with a private door. A half-duplex means just one shared neighbour; a townhouse sits in a longer row. Compare the actual homes on light, layout, space, and price rather than the label.

Can two generations of a family live in a half-duplex?

Yes — many do. Look for a layout that gives each generation privacy, such as a side-by-side home with bedrooms on separate floors or a self-contained lower level. The right floor plan matters more than the duplex label.

Is now a good time to buy a half-duplex?

The market has cooled. Attached-home prices across the region eased about 5% over the past year, and the April 2026 market was balanced — more listings to choose from and more room to negotiate.
