1 Hiring a remodeling contractor to build a second floor addition can run $100-$300 a square foot for the typical addition (2-3 bedrooms and a bath plus a flight of stairs), but can go as high as $400-$500 per square foot depending on complexity, quality of materials and local labor rates.uilding a second floor (also called a second story) can added much-needed space, but costs at least 20 percent more than building the same square footage at ground level.
