What Makes a Basement Suite "Legal"?
For a suite to be legally recognized and registered with the city, it must meet all of these requirements.
Separate Entrance
A dedicated entry point for the suite, fully independent from the main home's entry.
Egress Windows
Properly sized escape windows in all bedrooms, meeting fire safety requirements for below-grade spaces.
Ceiling Height
Minimum ceiling height requirements throughout all habitable areas of the suite.
Fire Separation
Fire-rated walls, ceilings, and doors separating the suite from the main dwelling, plus smoke and CO detection.
Adequate Parking
Off-street parking provisions as required by local zoning bylaws for secondary suite registration.
Separate Utilities
Depending on the property, separate metering or sub-metering for utilities may be required.
Permits & Inspections
Building, electrical, and plumbing permits with final municipal inspection and occupancy approval.

Frequently Asked
Questions
Everything you need to know before building your legal basement suite.
How much does it cost to build a legal basement suite in Calgary or Airdrie?
Costs vary based on your basement's existing condition, square footage, and finishes. Most projects involve work to add egress windows, separate entrances, and fire separation. We provide a detailed, transparent quote after an initial assessment.
How long does it take to get permit approval?
Permit timelines vary by municipality and project complexity, but our familiarity with local processes helps avoid common delays. We'll give you a realistic timeline during your initial consultation.
Can any basement be converted into a legal suite?
Most basements can be converted, though factors like ceiling height, window placement, and lot zoning can affect feasibility. We assess all of this during your free consultation.
Do I need a separate entrance for a legal basement suite?
Yes — a separate entrance is a core requirement for most jurisdictions to classify a suite as a legal secondary suite. We design and build the entrance as part of our service.
Will a legal suite increase my property taxes?
Registering a secondary suite may affect your property assessment. We recommend confirming with your municipality, but the rental income potential generally outweighs the tax impact significantly.
How is a legal suite different from a standard basement renovation?
A standard renovation creates finished living space for your household. A legal suite is a self-contained dwelling unit that meets code requirements for separate tenancy and can be legally rented out.
"Greater Works built our legal basement suite from scratch — permits, egress windows, separate entrance, full kitchen and bath. The whole process was smooth and transparent. We had a tenant within 3 weeks of completion."— David & Priya M., Calgary Homeowners
