A legal basement suite can add meaningful resale value and rental income to a Calgary home, and building one typically runs $180,000 to $250,000 as a fixed-price quote to meet City of Calgary code for egress, ceiling height, and fire separation. The added value depends on your neighbourhood, the quality of the build, and whether the suite is legal and registered. Your fixed-price quote will vary based on your selections and square footage, with appliances a separate purchase you make and we install.
