A few details only you can confirm

No dataset can answer these — they come from standing in the backyard.

Is there already a garden or laneway suite on this property?Recorded · No

Thanks — we’ve recorded that there isn’t another garden or laneway suite.

Will you keep an existing shed, garage, or other small building?Recorded · No

Thanks — the estimate assumes no other small buildings will remain.

Calculation assumptions

We’re using the current general zoning rules and the public building footprint on file.

Use a previous transition exception

Known main-house footprint (m², optional — not total floor area)

Things to confirm as the design develops

These don’t change today’s feasibility result, but your designer should review them as the project moves toward permit.

1Site & access2 items

Clear rear-yard passage

Professional review recommended

You report a clear access route. Emergency-access dimensions and fire-safety design must be checked at the permit-design stage.

Tree protection

Professional review recommended

Tree protection zones should be reviewed once the final suite location is developed. An arborist may be needed.

2Landscape & building details1 item

Floor area versus main house

Professional review recommended

The suite GFA must remain smaller than the main house.

Garden suite use permissionMeets the control
Recorded: Permitted use · Proposed: Garden suite
The mapped residential zone and your answers support the general accessory-suite use screen. Site-specific zoning and permit approval are outside this calculation.
Building heightMeets the control
Recorded: 6.3 m · Proposed: 6.3 m
The configured building height is within the recorded limit.
StoreysMeets the control
Recorded: 2 storeys · Proposed: 2 storeys
The configured storey count is within the recorded limit.
Rear setbackMeets the control
Recorded: 1.5 m · Proposed: 1.5 m
The measured rear setback meets the recorded minimum.
Left side setbackMeets the control
Recorded: 0.6 m · Proposed: 1.3 m
The measured left side setback meets the recorded minimum.
Right side setbackMeets the control
Recorded: 0.6 m · Proposed: 1.3 m
The measured right side setback meets the recorded minimum.
Separation from main houseMeets the control
Recorded: 7.5 m · Proposed: 7.5 m
The measured separation from main house meets the recorded minimum.
Footprint areaMeets the control
Recorded: 63 m² · Proposed: 30.67 m²
The measured footprint area is within the recorded limit. Public footprints may not match a survey. Assumes no other shed, garage, or ancillary building is retained.
Constraint layer screeningScreen recorded
Recorded: — · Proposed: Municipal layers screened
Available municipal constraint layers were checked with no flags. Tree protection is separate professional information for the next design step; public screening is not permit approval.
Maximum garden-suite floor areaMeets the control
Recorded: 120 m² · Proposed: 61.34 m²
The measured floor area is within the 120 m² limit. This figure is a conservative upper-bound estimate — the true zoning gross floor area, after any by-law-permitted deductions, can only be lower — so this result is reliable regardless of what those deductions would have been.
One-storey floor area limitNot applicable here
Recorded: Not applicable above one storey · Proposed: —
The one-storey floor-area limit only applies to a one-storey garden suite.
