St. Clair West: Detached to Legal Duplex + Laneway Suite

Turning One Home Into a Cash Flow Machine

  • Location: St. Clair West
  • Scope: Single-family to high-bedroom duplex + new 2-bed laneway suite
  • Construction Timeline: 12 months
  • Goal Achieved: Maximize rental income and force appreciation to pull out 100% of invested capital — and still cash flow every month

What We Did:

This was all about smart density. We took a large detached home and turned it into a legal duplex, with a 4-bedroom upper unit and a basement split into a two bedroom unit — purpose-built for high bedroom rents.

We didn’t stop there. We added a 1,000 sq ft, 2-bedroom laneway suite in the backyard — fully detached and fully rentable. The result was three strong rental streams on one lot, all fully legal and up to code.


Why It Worked:

  • Maximized rent by designing for multi-bedroom occupancy
  • Created extra value with laneway suite at zero land cost
  • Used durable finishes and efficient layouts to attract strong tenants
  • High appraisal led to full refinance and capital recovery
  • Still cash flows positively every month, even with new financing
