How much does building a new house cost in Toronto?

Declared construction values on Toronto new-house permits — custom infill and rebuilds after a teardown.

2,178 permits with a declared value, trailing 36 months. Medians and quartiles only — one outlier can't move them.

We publish a per-square-foot rate only where floor area is what the price actually scales with. For this work the correlation between area and declared value is 0.40 — too weak for a rate to predict your project. Multiplying your floor area by a published $/SF number would produce a confident-looking figure that the underlying permits do not support, so we show the value distribution instead.

• Floor area and storeys, plus whether a basement is walkout or underpinned.
• Site constraints — infill lots mean shoring, hoarding and no laydown area.
• Structure and envelope choices; steel beams and large glazing openings move the number quickly.
• Demolition and servicing of the old dwelling, usually permitted separately.

Declared construction values on City of Toronto building permits (tier C), trailing 36 months, minimum 12 permits before a guide is published. A declared value is what the applicant stated the work is worth — it can sit below final hard cost, which is exactly why GROUND also publishes awarded contract prices.

Declared values on custom homes are known to run below final hard cost — treat them as a floor, not a market price.
