A kitchen or bathroom renovation adds value everywhere in Saskatoon, but in an established neighbourhood like Grosvenor Park, where houses were mostly built in the same era, the gap between an updated and an original house of the same size is often the single biggest swing factor in price.
A finished basement or an added secondary suite is the other lever, and it only counts toward value once the City of Saskatoon has a permit on file for it. Without that permit, a lender or appraiser generally treats the extra space as if it were not there.
Public data reads the square footage on file; it cannot read whether a permit exists for the finish behind the drywall. Get your hand-reviewed valuation from Joel Dyck.
