Half Duplex | What it is

Half Duplex or Detached House

On many Vancouver and Burnaby streets these are now the two options at very different prices, and the newly built half duplex often sits on the exact lot the detached house used to occupy.

The short answer

A newly built half duplex puts you on an established street at a fraction of what a detached house on the same street costs, with current construction and a warranty. You give up the whole lot, one wall, and full control of the property. For many buyers that trade is what makes the neighbourhood reachable at all.

The trade in one sentence

You are buying the street rather than the whole lot. On the west side of Vancouver, in Burnaby, and across the east side, a newly built half duplex is frequently the only way into a neighbourhood where detached houses have moved out of reach.

What you actually give up is land, one shared wall, and unilateral control. What you keep is the location, current building code, a warranty, and no deferred maintenance.

What the shared wall means in practice

It means a party wall, and how it performs depends entirely on how it was built. Newly built homes are constructed to current code, which is meaningfully better on sound separation than the older stock people compare it to.

It also means shared decisions on anything structural: the roof, the envelope, drainage, and often the driveway. Those get agreed with one other household, which works well when both parties are reasonable and is genuinely difficult when they are not.

What you should check that a detached buyer would not

Whether you are buying the front or the back half, because they are different homes with different light, outdoor space, and street exposure.

How the strata is set up between the two owners, and whether the bylaws are ones you could live with for a decade.

Whether any part of the lot is exclusive to one side, particularly parking and outdoor space, and whether that is registered or just how it has been used.

Is this right for you

Works well if

  • The neighbourhood matters more to you than owning the whole lot
  • You want a new home rather than an older house needing work
  • A detached house on that street is genuinely out of reach

Does not work if

  • You want a large private yard, or complete control of the property
  • Shared structural decisions with one neighbour would frustrate you
  • You want the ability to redevelop the lot in future

Check before you offer

  • Front or back half, and what each gets in light, yard, and parking
  • The party wall construction, and what the builder used for sound separation
  • The strata arrangement and bylaws, in full, before removing subjects
  • Whether outdoor space and parking are exclusive use, and registered as such

Common questions

Is a half duplex worth less than a detached house?

It costs less, which is the point. On resale value this site does not forecast, and you should be sceptical of anything that does. What is measurable today is that a newly built half duplex reaches streets where detached houses cost several times more.

Can I renovate a half duplex freely?

Inside your own unit, mostly yes, subject to the strata bylaws. Anything touching the structure, the roof, the envelope, or the shared wall involves the other owner. Read the bylaws before you plan work, because a two-owner strata gives you no majority to fall back on.

Do half duplexes come with a yard?

Usually some private outdoor space, and typically a good deal less than a detached house on the same lot, since the lot is now carrying two homes. Whether it is exclusively yours or common property is a title question, not something to infer from how it looks.
