Why Don’t American Cities Build 3-Flats Anymore?

In cities like Chicago, Boston, and New York, the classic 3-storey walk-up is the backbone of the community. These "Three-Flats" provided affordable, high-quality housing for generations, yet in 2026, it is nearly impossible to build a new one in most American cities. In this video, we investigate the 3 invisible barriers that killed this perfect middle-ground of urban living. We break down the "Missing Middle" crisis and how rigid 20th-century zoning laws restricted most city land to single-family homes only. We examine the "Two-Stairwell" rule—a costly building code unique to the US and Canada that makes small apartment buildings financially impossible to construct. Finally, we look at how parking minimums force developers to sacrifice housing space for asphalt, making the classic, walkable 3-flat a relic of the past. Discover why America is stuck choosing between massive high-rises or sprawling suburbs in 2026.
