Site & Design | Lots, Setbacks & Coverage
How Your Lot Decides What You Can Build
Two lots with the same zone can hold very different buildings. Width sets whether you get a houseplex or a corner townhouse; depth sets the rear yard; grade sets how hard the foundation works. Every number on this page comes from the Schedule P Missing Middle Regulations. Read them against your specific parcel before you design.
Key Takeaways
- ✓A houseplex needs a 12 m minimum lot width; a corner townhouse needs 18 m near two streets.
- ✓The houseplex rear yard is the greater of 10 m or 25% of lot depth — often the binding limit.
- ✓Site coverage caps at 40% (houseplex) / 50% (townhouse); open space at 45% minimum.
- ✓Front 4 m, side 1.5 m, and 5 m between buildings on the same lot.
The Numbers
| Requirement | Schedule P value |
|---|---|
| Front yard setback (houseplex) | 4 m minimum |
| Side yard setback (houseplex) | 1.5 m minimum |
| Rear yard setback (houseplex) | The greater of 10 m or 25% of lot depth |
| Setback from a street (corner townhouse) | 2 m (5 m where a window faces a habitable room) |
| Building separation (both forms) | 5 m minimum where more than one building |
| Site coverage (houseplex / townhouse) | 40% / 50% maximum |
| Open site space (both forms) | 45% minimum |
| Minimum lot width (houseplex) | 12 m (14 m if more than one parking space required) |
| Minimum lot width (corner townhouse) | 18 m |
| Street proximity (houseplex) | Building within 30 m of a street (not a lane) |

Four Lot Types, Four Outcomes
Standard interior lot
The everyday Victoria lot. If it is at least 12 m wide and designated Traditional Residential, a houseplex is on the table. The rear-yard rule — the greater of 10 m or 25% of depth — usually decides how much building you get.
Corner lot
A corner lot at least 18 m wide near two streets unlocks the corner townhouse form, up to 12 units. The 2 m street setback is more generous than an interior lot’s front yard, which is why corners pack more in.
Deep lot
On a deep lot the rear yard is set by 25% of depth, not the 10 m floor, so a longer lot gives up more rear yard. Site coverage (40%) and the 1,410 m² combined floor-area cap become the binding limits.
Sloped lot
Grade interacts with the minimum 1.1 m ceiling height above grade for the lowest level and with retaining and ramp design. A sloped lot is buildable but adds cost and design work.
Best For
- ✓ Interior lots at least 12 m wide with enough depth to absorb the rear-yard rule.
- ✓ Corner lots at least 18 m wide near two streets, where the townhouse form pays off.
- ✓ Flat or gently sloped lots where grade does not force expensive retaining.
Usually Fails When
- ✕ A narrow lot falls below the 12 m houseplex (or 18 m townhouse) minimum width.
- ✕ A deep lot gives up too much rear yard to 25%-of-depth, shrinking the buildable area.
- ✕ Steep grade drives retaining and foundation cost past what the unit count supports.
What To Verify Before Spending Money
- → Surveyed lot width and depth — not the assessment-roll estimate.
- → Whether the parcel is a true corner lot with two qualifying street frontages.
- → How the rear-yard rule and 40% coverage cap interact on your actual dimensions.
