Start with St. Albert’s current suite guidance
St. Albert recognizes internal, garage and garden forms of secondary suite. The city’s current page says the use is available with several low-density dwelling types and requires a development-permit review before construction approvals.
Open the official St. Albert suite source ↗Do not assume a nearby Edmonton region project proves the same unit form is allowed here. The St. Albert property still needs its own zoning and permit check.
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.

What kind of unit?
Coach houses and garden suites introduce property-layout constraints that an internal secondary suite may avoid. That question should be resolved against the actual St. Albert project rather than a generic example.
Is the use allowed?
Land-use permission is the first gate. Confirm the parcel and proposed unit type before committing to architectural work.
Can the building comply?
Existing basements often need life-safety upgrades before they can function as approved dwelling units.
Can the site serve it?
Parking may be only one site issue; utilities, garbage access, lot coverage and detached-unit siting can matter too.
How to sequence a St. Albert suite project
Before detailed drawings, establish the parcel’s entitlement and the correct municipal category for the unit. Then test the design against code and servicing.
A tenant in place does not establish legality. Verify the municipal record and any outstanding permits or orders.
