Downtown Sioux Falls is finally getting genuine mixed-use density with the Switchyard project
Sioux Falls's most significant current downtown development is the Switchyard project, which broke ground in 2026 and combines a five-story, 60,000 square foot office building with two residential buildings totaling approximately 270 units and a parking garage, a genuinely dense, mixed-use format that is new for a downtown historically defined by lower-density commercial buildings. Construction on phase one, the office building, began in late fall 2026, giving the project a concrete, currently active timeline rather than a speculative future phase.
Switchyard sits within a broader downtown ambition captured in the proposed Riverline District, envisioning a mixed-use development anchored by a state-of-the-art convention center, hotels, public green space, and enhanced access to the Big Sioux River that runs through downtown. That river frontage is a genuinely underutilized asset in much of downtown Sioux Falls today, and the Riverline concept represents the city's attempt to activate it the way successful riverfront districts have in larger metros, at a scale appropriate to Sioux Falls's own size.
Business leaders entering 2026 expressed measured optimism about the broader development pipeline, while acknowledging that the full scope of upcoming projects had not yet fully come into focus at the start of the year, an honest, unhyped read on a market that is growing steadily rather than experiencing a sudden boom.
