Addressing the "Missing Middle" Production Gap

The "missing middle"—housing types that fall between detached single-family homes and large-scale apartment complexes—has seen a dramatic decline in production. According to the National Association of Home Builders, two-to-four-unit developments accounted for only 3 percent of U.S. multifamily production by the third quarter of 2025. This historic lag is often attributed to zoning codes that prioritize single-family residences on nearly 97 percent of residential land in some regions. To bridge this gap, economists like Jay Parsons of JPI advocate for "all of the above" solutions, including accessory dwelling units (ADUs), duplexes, and small-scale apartments.

Policy Barriers and the Developer’s Perspective

Legalizing density is only the first step; developers must also find the economic "pencil out" point for these projects. Current barriers often include excessive parking minimums, height restrictions, and the application of expensive commercial building codes to small-scale residential projects.

TRANSFORMATIVE ANALYSIS: Strategically, municipalities are beginning to recognize that small-scale density does not require high-rise construction. By allowing fourplexes that maintain the physical "form" and height of a traditional single-family home, cities can increase density without triggering significant NIMBY (Not In My Backyard) opposition. This "form-based" zoning shifts the focus from what a building is used for to how it fits into the neighborhood’s aesthetic fabric, facilitating a smoother approval process.
