The local suite route in Calgary
Calgary’s secondary-suite hub covers new suites, legalization, permits and the city’s suite registry. It distinguishes suites inside a dwelling from backyard suites and routes owners through the development and building approvals that apply to the specific property.

Alberta: the provincial layer
Alberta’s building code has specific requirements for houses with secondary suites, while municipalities decide where suites are allowed through local land-use bylaws.
Alberta secondary-suite building code ↗Four things to establish before the renovation
What kind of unit?
Detached accessory units usually add setbacks, site coverage, access or servicing questions beyond those for an internal suite. That question should be resolved against the actual Calgary project rather than a generic example.
Is the use allowed?
Do not assume a provincial housing reform means every design is automatically allowed on every lot. Verify the local implementation and exemptions.
Can the building comply?
Existing basements often need life-safety upgrades before they can function as approved dwelling units.
Can the site serve it?
Site constraints can include parking, sewer and water capacity, electrical service, waste access and setbacks for a detached unit.
How to sequence a Calgary suite project
Treat permission for another dwelling and approval of the construction as separate questions. Zoning answers one; building and trade permits answer the other.
A real-estate listing can describe a suite without proving it is legal. Ask for the municipal approval history before valuing it as an approved unit.
