Calgary rents are strong.
Your basement is empty.

A legal secondary suite is the highest-return renovation in Calgary. A typical two-bedroom basement suite rents long-term while adding serious resale value to your home.

We handle the entire path to a registered legal suite: layout design, permits, separate entrance, egress windows, fire and sound separation, kitchen, bathroom, inspections and final registration.

  • Private entrance and separate address
  • Fire-rated and soundproofed construction
  • Egress windows in every bedroom
  • Eligible for the $80,000 federal loan at 2%
