America's approach to housing, largely built around a mid-20th-century model of single-family homes and sprawling suburbs, is increasingly misaligned with the nation's future needs and demographics. As the United States approaches its 300th birthday, the housing shortage and its associated affordability crisis are seen as foundational issues impacting economic opportunity, cost of living, and political polarization.
The current housing paradigm, established after the Great Depression and World War II, prioritized large single-family homes, ample garages, and extensive commercial strips. This model was embedded in law through rigid zoning codes, midcentury lending standards, and the common practices of planners and builders. However, this framework is becoming less viable as household sizes shrink, the population ages, and climate change presents new challenges.
Projections indicate a shift in demographics. With lower immigration rates, the U.S. Census Bureau anticipates a future with fewer families and working-age adults and a significant increase in seniors by 2076. This demographic inversion is a stark contrast to the baby boom era that fueled suburbanization.
Despite these challenges, historical precedent offers reasons for optimism. The U.S. has demonstrated a capacity for significant societal reorganization when necessary. Cities have transformed over time, and the growing "yes in my backyard" (YIMBY) movement is already pushing for reforms to roll back restrictive policies that hinder home construction. These reforms are slowly beginning to improve affordability in some areas.
Suburban Transformation
Experts envision a future where suburbs, where most Americans live, undergo significant adaptation. By 2076, neighborhoods in areas like Southern California could feature a mix of housing types, including accessory dwelling units (ADUs), subdivided larger homes, triplexes, and small apartment buildings integrated with existing single-family residences. This increased density, coupled with potential widespread adoption of shared autonomous vehicles, could free up land currently used for parking and ease housing costs.
The traditional separation between residential and commercial zones may also soften, with local businesses and services integrating into neighborhoods. This shift could foster more connected public spaces and richer daily life within suburban areas. The incentive to redevelop single-family lots into more economically valuable, denser housing is high in expensive markets, provided regulations permit it. YIMBY successes at the state level have already enabled ADUs and denser housing options in many areas, leading some to predict the obsolescence of detached single-family zoning.
These zoning reforms are also seen as crucial for an aging population, allowing older homeowners to adapt their properties into smaller, more manageable units. Beyond residential areas, aging commercial districts, such as malls and strip malls, are also candidates for conversion into housing and mixed-use developments, with an increasing number of states allowing multifamily housing in these zones. The repeal of parking minimums further facilitates the redevelopment of underutilized land.
The Need for Urban Planning
While reforms are progressing, the pace of new home construction remains slow, influenced by economic factors like high mortgage rates, rising material and labor costs, and workforce shortages. Furthermore, some local governments are finding ways to circumvent new housing laws. Experts argue that market forces alone are insufficient and that a revival of comprehensive urban planning is essential.
Critics like Robert Goodspeed, an associate professor of urban planning at the University of Michigan, contend that the YIMBY movement has overlooked the importance of planning in creating well-designed, high-quality communities. Current zoning practices, which micromanage what can be built, are seen as a source of problems, often disconnected from how people actually want to live. Urban planning, in contrast, focuses on the public realm and essential infrastructure like roads, transit, and parks, creating cohesive and functional communities.
Effective street design is a key component of urban planning. While many older cities feature grid systems, most post-World War II suburbs have meandering streets and cul-de-sacs that disconnect neighborhoods. A connected street network is crucial for accommodating increased density, allowing for better movement and preventing traffic congestion. Planners advocate for a return to the civic ambition seen in late 19th and early 20th-century urban design, where street grids facilitated growth and integrated residential and commercial areas.
New Cities and Repaired Ones
Ambitious projects, such as the proposed new city in Solano County, California, aim to build housing from scratch with a focus on pedestrian-centered design and integrated living. While such endeavors face significant regulatory hurdles, they highlight a demand for more walkable urban environments. Research indicates a significant portion of Americans prefer walkable areas, even if it means smaller homes.
However, the most promising path to more walkable and vibrant communities may lie in the repair and retrofitting of existing cities and suburbs. Alicia Pederson, founder of Courtyard Urbanist, predicts a potential "golden age of American city-building" if urban planning is revitalized. This could involve creating housing options that offer the benefits of urban life alongside the spaciousness and green space often associated with suburban homes, such as European-style courtyard blocks.
An Uncertain Future
The future trajectory of American housing remains uncertain. Some predict continued sprawl, potentially exacerbated by autonomous vehicles, while others foresee a shift towards denser urban cores and renewed growth in Midwestern cities. The development of shared autonomous vehicle systems could also encourage density rather than sprawl, depending on policy choices.
The current housing system has led to widespread unaffordability and limited choices, contributing to societal anger. However, by embracing a more open and varied approach to housing, and by thinking strategically about community development, the U.S. may move beyond its present limitations. Just as cities like New York and Boston experienced dramatic comebacks, future housing solutions could offer greater variety, affordability, and imagination, enabling American life to evolve.
