Does your lot's frontage qualify for 5 or 6 units? Vancouver's real thresholds

"My lot is bigger than my neighbour's. Why does theirs qualify for six units and mine only gets four?"

We hear a version of this question often enough that it deserves its own answer, separate from the general zoning explainers. The short version: Vancouver's R1-1 zoning does not decide unit count from lot area alone. It tests a second, independent number, site frontage, and a lot can pass the area test and still fail the frontage test.

The two numbers, side by side

Vancouver's R1-1 District Schedule sets minimum site area and minimum site frontage together, as a pair, for each unit-count band. Both have to be met. Neither substitutes for the other.

• 3 to 4 units: minimum site area 306 m², minimum site frontage 10.0 m
• 5 units: minimum site area 464 m², minimum site frontage 13.4 m
• 6 units (market strata, the standard ceiling): minimum site area 557 m², minimum site frontage 15.1 m
• Up to 8 units where the project is registered as 100% secured rental tenure, on a lot that already clears the 6-unit thresholds

A standard Vancouver lot, the classic 33-foot frontage, measures roughly 10.06 metres at the street. That clears the 10.0-metre minimum for the 3 to 4-unit band comfortably. It does not come close to the 13.4 metres needed for 5 units, and it is nearly 5 metres short of the 15.1 metres needed for 6.

This is the part that surprises people: a 33-foot lot with a long, deep run can have plenty of total square footage, sometimes enough to clear the 557 m² area minimum for 6 units on paper, and still not qualify, because the frontage number never moves no matter how far back the lot runs.

Why area and frontage are tested separately

Area describes how much land there is. Frontage describes how wide the lot is where it meets the street, and that width is what actually determines whether homes can be arranged side by side with their own entries, their own light, and workable separation between units.

Two lots can share an identical area and produce very different buildings. A wide, shallow lot has room to line units up across the front. A narrow, deep lot has to stack that same square footage differently, and past a certain point there simply is not enough width at the street to fit another home beside the ones already there, regardless of how much depth is available behind them. The zoning schedule tests both numbers because area alone would let a narrow sliver of land claim a unit count it cannot physically support at the street.

What actually changes the answer

Lot assembly

Combining two adjoining lots increases both figures together, area and frontage, which is one legitimate way a pair of narrower individual lots can reach a higher band than either could alone. Assembly is its own process. It requires a subdivision or consolidation application with the city before the combined frontage exists as a single legal parcel that a permit application can rely on. It is not something a feasibility review can assume; it has to be confirmed and processed on its own timeline.

Secured rental tenure

Registering a project as 100% secured rental tenure raises the ceiling from 6 units to 8 on a lot that already clears the 6-unit area and frontage minimums. It is a bonus on top of qualifying, not a way around the underlying thresholds. A lot that fails the 15.1-metre frontage test for 6 units does not reach 8 by going rental; it is still evaluated against the band its actual frontage supports.

Corner lots need their own check

A corner lot has two street-facing sides, and it is tempting to assume the longer of the two counts as frontage. The zoning bylaw defines site frontage on its own terms, with its own diagrams, and that definition does not automatically track whichever side measures longer. Corner lots come up often enough in our reviews that we treat the frontage figure as something to confirm against the bylaw specifically, not infer from the lot's shape on a map.

Where the real number comes from

A lot's frontage is a matter of survey record, held with the subdivision plan at the Land Title and Survey Authority of BC. It is not the number on a real estate listing, and it is not always the number a tax assessment implies. We confirm the surveyed frontage as one of the first steps in a feasibility review, because it is one of the two numbers that decides which band a lot is actually in, before any design work starts.

The practical takeaway

If you own a standard 33-foot Vancouver lot, plan around the 3 to 4-unit band unless assembly with a neighbouring lot is realistically on the table. If your lot is wider than standard, at 40, 44, or 50 feet, it is worth having the exact frontage measured against the 13.4 and 15.1-metre thresholds before assuming a higher unit count is automatically available. Area gets most of the attention in casual conversation about multiplex zoning. Frontage is the number that actually gates the top two bands, and it is worth knowing before it becomes a surprise midway through a design.
