Before you price it
- Check zoning first: setbacks, height and lot coverage decide the size you can build.
- A loft or bonus room changes the job: one Ottawa source starts it at about $250 per square foot. Living space above a garage is a garage suite, with its own rules.
- Planning a heated floor? See heated garage slab cost.
- The full budget walk-through is in our detached garage cost guide.
