Four things that decide whether a basement suite is straightforward or expensive.
Ceiling height comes first. Measure from the concrete floor up to the bottom of the joists. Under about 6'7" and you're into lowering the floor, which means underpinning or bench footing. That's the biggest number on most quotes, and people find out about it way too late.
Egress is second. Every bedroom in a suite needs a window big enough to climb out of. If there's no opening in the poured concrete yet, that's a concrete cutting crew, a lintel, and a window well with proper drainage. It's not a small line item, so count your bedrooms after you know where the windows can go, not before.
Third is water. White chalky residue at the base of the walls, dark staining near the floor, or a musty smell a couple days after rain all mean moisture is getting through. Drywall over top of that just hides the problem until it's mould. Check your downspouts and how the ground slopes away from the house. In older Burnaby homes the perimeter drain might still be clay tile from the seventies.
Fourth, nothing gets covered until it's been inspected. If anyone offers to board over rough-in early to save time, that's costing you money later.
