A legal basement suite in Calgary can earn roughly $1,200–$2,000+ per month in rent, depending on size, location and finish — making it one of the strongest returns in the home. Here's what you can earn and what it takes.

Calgary’s Rental Market Makes Suite Development Attractive

Legal vs Illegal Suite: The Income Difference

Legal suites typically command $200–$400/month more than equivalent illegal (unpermitted) suites — better tenants, ability to advertise openly, no risk of bylaw enforcement forcing closure.

ROI Calculation: Does Suite Development Pay?

Example: 2-Bedroom Legal Suite

  • Suite development cost: $85,000
  • Monthly rent: $2,100
  • Annual gross income: $25,200
  • Expenses (5% vacancy, $3,000 maintenance, $200/mo utilities included): ~$8,000/yr
  • Net annual income: ~$17,200
  • Gross yield: ~20%/year on investment
  • Simple payback: ~5 years

That’s a very strong return — on top of the $80,000–$120,000 in added property value from having a legal suite.
