A permitted secondary suite with clean rent records and a separate entrance generally adds real value on top of the base home, while an unpermitted or undocumented second unit can add close to nothing, since a buyer's lender will not count income it cannot verify.
Location and unit configuration matter as much as the second suite itself. A two-family home near the University of Saskatchewan or a hospital tends to draw a deeper rental-focused buyer pool than the same configuration in a family-oriented suburb.
