The Missing Middle's Missing Link: Why Duplexes Aren't Always Affordability Heroes
Often championed as the silver bullet for America's housing crisis, "missing middle" housing — like duplexes and townhomes — isn't automatically making homes cheaper. The core problem lies in the disconnect between increasing housing options and truly addressing affordability for struggling households.
The narrative is compelling: America's housing crisis can be solved by simply building more diverse housing types. Specifically, a renewed focus on the "missing middle"—duplexes, triplexes, townhomes, and small-scale multi-family units—is often touted as the pragmatic path to greater affordability. But a closer look reveals a crucial gap in this increasingly popular policy push: simply allowing more of these housing types doesn't automatically translate into genuinely cheaper homes.
For years, restrictive single-family zoning across vast swathes of U.S. cities has been rightly blamed for exacerbating housing shortages and driving up prices. The idea behind the missing middle movement is to reintroduce the diverse housing options that characterized neighborhoods before mid-century zoning changes. On paper, it makes sense: more units per lot should mean more supply, and smaller units should mean lower price points.
The Cost Conundrum
The reality, however, is more complex. Building a duplex isn't half the cost of building two separate single-family homes. Land acquisition, labor, materials, permits, and financing costs remain substantial regardless of the unit count. In high-demand areas, land values are often the primary driver of housing costs, and simply adding a second or third unit to a parcel doesn't magically cut that initial land cost per unit in half. Developers still need to recoup their significant investments, and new construction, even of these smaller-footprint homes, often prices at or near the market rate for new housing, not necessarily below the cost of existing, older single-family homes or at levels truly accessible to low-income earners.
What often emerges are newly constructed townhomes or small apartment buildings that cater to middle- and upper-middle-income buyers or renters, offering an alternative to larger detached homes but not necessarily solving the affordability crunch for those most burdened by housing costs. For many, these units still represent a substantial financial hurdle, especially when factoring in today's elevated mortgage rates.
Market Forces and Investment Appetites
Another factor is the market itself. In desirable neighborhoods, loosening zoning to allow missing middle housing can, paradoxically, increase land values further if not managed carefully. The potential for higher density makes a parcel more valuable to a developer, and that increased land cost gets baked into the final price of the new units. While this provides more housing stock, it doesn't inherently make it more affordable.
Furthermore, these types of properties—especially duplexes and small multifamily units—can be attractive to real estate investors, further reducing the supply available to owner-occupants and potentially pushing up rental prices. Without specific policy mandates for affordability, such as inclusionary zoning or direct subsidies tied to the development, new missing middle housing can simply become another segment of the market rather than a targeted solution for those struggling to find an affordable place to live.
Beyond Housing Type: The Broader Affordability Challenge
To truly tackle the affordability crisis, policymakers need to look beyond just the type of housing being built. While diversifying housing stock is important for healthy, vibrant communities, genuine affordability requires a multi-pronged approach:
- Targeted Subsidies: Direct rental assistance programs and homebuyer down payment assistance can bridge the gap for low- and moderate-income households.
- Inclusionary Zoning: Requiring a percentage of new developments, including missing middle projects, to be set aside for affordable units, often with income restrictions.
- Expedited Permitting: Streamlining bureaucratic processes can reduce development costs and timelines, which can translate to slightly lower prices.
- Public Investment: Direct investment in affordable housing development by local and federal governments remains critical.
"Missing middle" housing is a valuable piece of the housing puzzle, offering density and diverse living options. But it's not a standalone panacea for affordability. Without pairing these zoning reforms with robust, targeted policies designed to guarantee accessible price points, the promise of cheaper housing might just remain a missing link in the middle of our ongoing housing crisis.
