A secondary suite differs from a spare room or an unpermitted garage conversion because it needs its own entrance in most cases, working smoke and carbon monoxide detectors, and a sign-off from a city inspector, not just a contractor's word that the work is done. Skipping that step does not make the space illegal to live in, but it makes the income invisible to underwriting, and it is exactly the kind of gap a buyer's home inspection, typically $400 to $600, tends to catch before financing closes.
Zoning is the second gate. Most residential lots inside Saskatoon allow a secondary suite under the City of Saskatoon's zoning bylaw, though lot size, parking and what is already built on the property can still rule it out on a specific address, so a call to the city's planning department before renovation work starts saves money compared with finding out after.
A permitted suite adds real, financeable value to a Saskatoon home; an unpermitted one, even a nicely finished one, often adds close to nothing on paper because no lender can underwrite income that was never inspected.
