The two permits do different jobs. A development permit confirms your lot's zoning actually allows a secondary suite in the first place, and a building permit confirms the construction meets the building code once the use is allowed, covering everything from fire separation to a legal exit.
Permit status is what a lender or appraiser actually checks, not how nice the flooring looks. The City of Saskatoon's inspection confirms whether the suite counts as legal secondary income, and that single line item is often the gap between an online estimate and what the space is genuinely worth.
A basement built without a permit can still be legalized after the fact, but a lawyer and a home inspection, typically $400 to $600, before you list is the way to find out what the retrofit actually needs. Get your hand-reviewed valuation from Joel Dyck.
