What matters for an addition in Kanata

Lot size and setback room

Lot depth and shape vary from street to street, so we measure your property rather than assuming from a neighbouring one.

What kind of addition fits

Kanata is a large, established suburb in Ottawa's west end with a mix of subdivisions built from the 1980s onward alongside newer infill development, and it's home to much of the city's tech sector.

Foundation and ground conditions

We check the existing footing type before tying a new one into it. New footings go below frost depth, commonly about 1.5 m.

Recent Project in Kanata

This Kanata project added a ground-floor room across the back of a two-storey home. The new walls are framed the full width of the house, with door and window openings in place, and the new foundation is wrapped and protected along the outside. The photo shows the framing stage, before the roof framing and sheathing went on.

Why we measure every Kanata lot on its own

Kanata grew through several distinct waves of subdivision development, from established streets built decades ago to newer infill lots still being completed. That range means two houses on the same Kanata street can have very different room to build under the rear yard setback, which is 25 percent of lot depth in most urban neighbourhood zones. Before proposing a second-storey addition versus a ground-floor extension, we measure your specific lot rather than assuming from the general age of the neighbourhood.

What a Kanata quote should confirm

Your lot's actual rear-yard measurement

Not a general statement that additions are common in Kanata. Ask for your property's specific setback figure.

The age and construction of your house

Older and newer sections of Kanata can have different foundation types and structural conditions, which affects what a second-storey addition needs from the existing structure.

Egress requirements for each new bedroom floor

Ask to see the specific window opening size on the drawings, sized to Ontario Building Code Div. B 9.9.10.

The realistic City of Ottawa permit timeline

Ask for your project's specific estimate in writing.

25% Rear yard setback as a share of lot depth, most urban neighbourhood zones (minimum 6 m)
1.5 m Common local footing depth used to clear frost

Kanata home addition questions

Do you have recent projects in Kanata?

Yes. Our recent rear room addition in Kanata is shown above, and when we visit we can walk you through other jobs that match your addition.

Are second-storey additions common in Kanata?

They're a practical option on lots where the rear-yard setback leaves limited room to build out, which is common on some of Kanata's more established streets.

Can I add a secondary suite in Kanata?

In most cases, yes. Ottawa's new Zoning By-law limits the number of units per lot by lot size and zone, and the unit needs its own entrance and code-sized egress windows. We confirm your lot's limit before designing.

We'll check the lot, the zoning and the ground before quoting anything.
