A triple car garage in Calgary typically requires both a development permit and a building permit, and needs to fit your lot's coverage, setback and height rules — most triple detached garages start around 30 by 24 feet or larger. Site grading, foundation type and whether you want it heated all shape the design, so planning matters before the first shovel. Jonathan Edwards is involved on every job, giving you one point of contact and a fixed-price quote with no surprises.
Three Doors, Endless Possibilities
A triple-car garage is the standard for Calgary estate homes and acreage properties. It’s not just about fitting three vehicles — it’s workshop space, toy storage (sleds, RVs, boats), and the foundation for a proper garage suite.
