Legality runs through the City of Saskatoon's zoning bylaw and building code, which set minimum ceiling height, egress window size and a separate entrance for a suite to count as a legal secondary unit rather than an informal basement apartment. A suite built without those permits shows up in no official record, so an automated estimate and most lenders price the house as though it does not exist.
Forest Grove's older bungalow stock, much of it on lots with lane access, suits this kind of conversion well, but the value only holds up if the work was inspected and closed out with the City rather than simply completed. A buyer's lawyer or lender asking for the permit file and finding nothing turns a selling feature into a financing problem.
Joel Dyck confirms permit status before pricing a Forest Grove listing with a secondary suite, then compares it against sales of similarly legal units rather than informal ones. Get your hand-reviewed valuation from Joel Dyck.
