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.
The full spread, not an average
| Percentile | Declared value |
|---|---|
| P25 — smaller jobs | $500K |
| Median | $900K |
| P75 — larger jobs | $1.2M |
| Largest in sample | $16.8M |
2,069 permits with a declared value, trailing 36 months. Medians and quartiles only — one outlier can't move them.
Why two of these quote differently
- 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.

Where these numbers come from
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.
