The local suite route in Lethbridge
Lethbridge requires permits when creating, legalizing or materially altering a secondary suite. The city distinguishes zones where suites are permitted from those where they are discretionary and publishes local parking, access and lookup information.

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?
A detached unit can trigger a second layer of siting and servicing rules even when an internal suite is relatively straightforward. That question should be resolved against the actual Lethbridge project rather than a generic example.
Is the use allowed?
Verify the current planning permission for this parcel rather than relying on a neighbour’s recent project.
Can the building comply?
Code compliance is a separate gate: check egress, fire separations, life-safety alarms, ventilation and structural adequacy. That question should be resolved against the actual Lethbridge project rather than a generic example.
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 Lethbridge suite project
The project is not finished at permit issuance. Track inspections and final sign-off so the approval record matches the completed dwelling.
For resale properties, the most useful evidence is the municipal file, not the number of years the unit has been rented.
