Zoning & Policy | Houseplex vs Townhouse
Houseplex vs Corner Townhouse
Victoria's Missing Middle rules define two distinct building forms, not one. The houseplex is the everyday form — three to six units on a standard lot. The corner townhouse is a separate, denser form reserved for corner sites, where up to twelve units are allowed. Both come straight from the Schedule P Missing Middle Regulations. Which one is on the table for your lot is decided by its width and street frontage.
Key Takeaways
- ✓A houseplex is 3–6 units; at least half must have direct outside access. It works on any Traditional Residential R1-B/G/A or R-2 lot.
- ✓A corner townhouse reaches up to 12 units — but only on a corner lot at least 18 m wide near two streets.
- ✓The townhouse carries a higher FSR (1.1 vs 1.0) and site coverage (50% vs 40%).
- ✓The 3-bedroom rule, 5 m building separation, 33 m² minimum unit, and 0.77 parking ratio apply to both.
Side by Side
| Rule | Houseplex | Corner Townhouse |
|---|---|---|
| Where it is allowed | Any Traditional Residential lot in R1-B, R1-G, R1-A, or R-2 | Corner lots only |

| Open site space (min) | 45% | 45% |
| Minimum lot width | 12 m (14 m if more than one parking space is required) | 18 m |
| Street proximity | Building within 30 m of a street (not a lane) | Within 36 m of at least two streets |
| Street setback | 4 m front; 1.5 m side | 2 m from a street (5 m where a window faces a habitable room) |
| Building height | 11 m flat roof / 12 m other roof | 11 m flat roof / 12 m other roof |
All figures from the City of Victoria Schedule P — Missing Middle Regulations (sections 1–4 and 6).
Rules That Apply to Both Forms
The 3-bedroom rule
Both forms are permitted only if the greater of two units, or 30% of the units, are three-bedroom homes. Bedrooms in a secondary suite can count toward the principal unit’s total (a 2023 amendment), which makes the rule easier to hit.
Building separation
Where more than one building sits on the lot, they must be at least 5 m apart — the same for both forms.
Parking at 0.77 per unit
Both forms start at 0.77 vehicle spaces per dwelling unit, with no parking required for secondary suites, affordable units, or visitors. Transportation demand measures can drive the requirement to zero.
Minimum unit size
No dwelling unit can be smaller than 33 m², and combined floor area on a lot is capped at 1,410 m² — both forms.
Best For
- ✓ Houseplex: a standard interior Traditional Residential lot at least 12 m wide — the most common Victoria site.
- ✓ Corner townhouse: a corner lot at least 18 m wide near two streets, where the extra FSR and unit count pay for the design.
- ✓ Either form when the lot is designated Traditional Residential and zoned R1-B, R1-G, R1-A, or R-2.
Usually Fails When
- ✕ You assume a corner townhouse is available on an interior lot — it is corner-only.
- ✕ The lot is narrower than the form’s minimum width (12 m houseplex / 18 m townhouse).
- ✕ The 3-bedroom mix is ignored until late design, forcing a rework of the unit plan.
What To Verify Before Spending Money
- → Lot width, depth, and whether the parcel is a true corner lot with two street frontages.
- → The OCP Traditional Residential designation and the zone — both must be present.
- → How the 3-bedroom requirement interacts with your target unit mix before drawing.
