What Are the Legal Suite Requirements in Calgary?

Calgary permits legal suites (secondary suites) in most residential zones under specific conditions. The City of Calgary requires full compliance with the Alberta Building Code (ABC) and Land Use Bylaw 1P2007 before you can legally rent to tenants.

Key Requirements

Building Code & Design Standards

  • Minimum floor area: 320 sq ft (excluding storage)
  • Separate, lockable entrance required
  • Dedicated kitchen with sink, stove, and fridge
  • Full bathroom with toilet, sink, and shower/tub
  • At least one bedroom
  • Fire-rated walls separating suite from main residence (2-hour rating)
  • Approved egress windows (bedroom and living area)
  • Separate electrical panel or dedicated circuits
  • Independent heating and cooling systems

Permits & Approvals

You must obtain:

  • Development Permit from City of Calgary Planning ($350–$600)
  • Building Permit ($800–$1,500 depending on scope)
  • Utility separations (gas, electric, water lines)
  • Final Occupancy Inspection before tenant move-in

Processing times average 4–8 weeks for permits.

Zoning & Property Restrictions

Not all Calgary properties qualify. Check:

  • Your land use designation (most single-family zones allow one legal suite)
  • HOA or covenant restrictions (many prohibit rentals)
  • Lot size and parking requirements (minimum 1.5 parking spaces per main residence)
