The 2026 market range
Toronto garden and laneway suites are landing in the same broad $400 to $650 per square foot all-in market range as the rest of the GTA in 2026 — with the variance driven by site access, servicing distance, and finish level rather than by geography.
Typical all-in cost by size
Illustrative 2026 ranges we see across the Toronto market:
- Compact studio (~350–450 sq ft): $225k–$325k
- One-bedroom (~550–700 sq ft): $275k–$450k
- Two-bedroom (~800–1,000 sq ft): $350k–$550k+
Two-storey designs, high-end kitchens, and complex servicing push higher. The Modular X approach is to establish a hard budget after a feasibility review and lock the module price before construction starts.
Toronto-specific cost items
- Development charges exempt or deferred. Since Bill 23 and Toronto's ARU framework, garden and laneway suites don't carry the DC burden that hit pre-2023 second units. This is a meaningful saving — often $30k–$50k+ compared to the pre-reform era.
- Building permit fee: roughly $18.56/m² for residential construction (2026 rate). For a 65 m² (~700 sq ft) suite that's about $1,200 in permit fees. Toronto does not refund the fee at completion (unlike Mississauga).
- Soft costs: $25k–$70k range. Engineering, arborist reports, surveys, grading and drainage plans, utility connection permits. Bespoke designs push toward the top; pre-approved plans push toward the bottom.
- Parkland dedication may apply in some cases — check with Toronto Planning.
The fire access line item most owners miss
Toronto's fire-access rules trigger significant equipment costs based on the door-to-street distance:
- Suites where the door is less than 45 m from the street — no special fire-suppression equipment beyond code minimums.
- Suites where the door is between 45 m and 90 m from the street — residential sprinkler system, exterior strobe, and interconnected smoke/CO alarms are all required. Budget an incremental $15k–$30k.
- Suites where the door is more than 90 m from the street — typically not permitted; feasibility check first.
This is the single most commonly missed line item in owner-run cost estimates. A quick measure from the front lot line to the proposed suite door tells you which bucket you fall into.
Made-in-Toronto pre-approved plans
Toronto's Made-in-Toronto program offers pre-approved studio and two-bedroom designs for both garden and laneway configurations. Two concrete benefits:
- The design fee disappears.
- The permit application skips the building-design review — reviewers only check the site-specific components (site plan, servicing, grading). That's faster and safer.

Rental income context
Well-finished two-bedroom garden suites in Toronto commonly rent around $3,000 to $3,300 per month; one-bedrooms and studios scale down from there. Illustrative market data — validate for your neighbourhood.
