Home Addition Stages
50%
home addition pricing in Toronto and Southern Ontario usually depends on scope, site conditions, access, finish level, permits, and trade work. Use the planning range below to understand common budget levels before requesting a written estimate.
Final pricing is confirmed only after scope, site conditions, selections, and written assumptions are reviewed.
| Planning level | Typical range | Typical scope |
|---|---|---|
| Refresh | Confirm after site review | Cosmetic updates, limited trade changes, simpler finishes. |
| Mid-range | $180k-$500k+ | Layout refinement, new finishes, selected trade work, clearer allowances. |
| Major | Site-specific estimate required | Structural, permit-sensitive, full-system, custom, or high-finish work. |
