How Much Does a Basement Suite Cost in Calgary?
In 2026, Calgary basement development costs vary by floor area, existing rough-ins, egress, mechanical work, permit path, and finish level. OAF’s Calgary basement-development service uses project-specific fixed-price scopes; the ranges below are planning guidance, not a quote.
Lifestyle Basement Costs
A lifestyle basement is a finished space for your family’s use (not a rental unit). Typical pricing:
- Basic layout (1 bedroom, 1 bathroom, living area): $45,000 to $55,000
- Standard layout (2 bedrooms, 1 bathroom, living area, wet bar): $55,000 to $68,000
- Premium layout (2+ bedrooms, full bathroom, home theatre, custom finishes): $68,000 to $85,000
Legal Suite (Secondary Suite) Costs
A legal suite is a self-contained rental unit that meets all City of Calgary building code requirements:
- Basic legal suite (1 bedroom, kitchen, bathroom, separate entrance): $58,000 to $70,000
- Standard legal suite (2 bedrooms, full kitchen, bathroom, laundry): $70,000 to $85,000
- Premium legal suite (2 bedrooms, upgraded finishes, in-suite laundry): $85,000 to $100,000+
What Is Included in OAF’s Fixed Price?
When the work is included in an OAF Fixed-Price Agreement, the proposal identifies:
- All materials and labour
- Permit applications and City coordination included in the approved scope
- Required inspections identified for the approved work (which may include framing, plumbing, electrical, insulation, or final)
- Project management
- Clean-up and debris removal
- Closeout and occupancy documentation where applicable to the approved scope
SSIP Status: Confirm Current Intake
If you are building a legal suite, you may qualify for the City of Calgary’s Secondary Suite Incentive Program (SSIP), which has a maximum of $10,000 toward eligible work when intake is open. New applications are currently waitlisted, so confirm live status before relying on the program. The City does not maintain an approved SSIP contractor list; OAF helps homeowners plan the suite scope, permit path, and reimbursement documentation.
