Missing Middle Multifamily Starts Decline 24%

Starts for 2- to 4-unit multifamily housing, often referred to as 'missing middle' housing, experienced a significant decline of 24% year-over-year. This downturn, as reported by the National Association of Home Builders (NAHB), is largely attributed to restrictive zoning regulations that impede the development of 'light-touch' density projects. These types of housing developments are crucial for providing more affordable and accessible housing options in suburban and urban areas, bridging the gap between single-family homes and larger apartment buildings.

The "missing middle" housing concept encompasses a range of housing types, including duplexes, triplexes, fourplexes, and townhouses, that are compatible with existing single-family neighborhoods. These developments typically offer more housing units on a smaller footprint than traditional single-family homes but are less dense than large apartment complexes. The NAHB's analysis indicates that the slowdown in starts for these specific housing types suggests that local land-use regulations, particularly zoning ordinances, are acting as a primary barrier to their construction. Such regulations can include minimum lot sizes, restrictions on building height, limitations on the number of units per building, and prohibitions on multi-family structures in areas zoned exclusively for single-family residences.

The decrease in starts for 2- to 4-unit buildings is particularly concerning given the ongoing housing affordability crisis in many parts of the United States. These housing types are often more attainable for first-time homebuyers and renters than detached single-family homes or larger, more expensive apartment buildings. By limiting the supply of these intermediate housing options, restrictive zoning practices can exacerbate housing shortages and drive up costs. The NAHB's findings highlight a critical need for zoning reform at the local level to encourage the development of a more diverse housing stock that can better meet the needs of a growing population and address affordability challenges.

This trend suggests a broader challenge for urban planners and policymakers aiming to increase housing supply and promote more inclusive communities. The "light-touch" density that missing middle housing represents is often seen as a more palatable approach to increasing density compared to large-scale apartment projects, as it can integrate more seamlessly into existing neighborhoods. However, even these less intensive forms of density are facing significant hurdles due to entrenched zoning codes. The NAHB's data serves as a stark indicator that without changes to these regulatory frameworks, the construction of essential housing options will continue to lag, impacting housing availability and affordability across the country.
