America's housing supply was built for a world that no longer exists, and as the nation approaches its 250th anniversary, the question of what will replace it is among the most critical for the coming decades. Building enough homes of the right kind in the right places is essential for economic opportunity and growth. The housing shortage is upstream of many national problems, including the cost of living, zero-sum politics, and a persistent national bad mood.
The root of the problem lies in a nearly century-old governance paradigm that has been cracking under strain. Since the end of the Great Depression and World War II, suburbia—with big single-family homes, two-car garages, and giant strip malls—became the default blueprint, codified by rigid zoning codes, midcentury lending standards, and professional norms. This system has kept homes scarce, expensive, and sprawling, fueling an affordability crisis that now dominates politics.
Demographic and Climate Shifts Demand Change
In the next 50 years, this model will become even more misaligned with American life. Households are shrinking, the population is aging, and if low immigration rates continue, the US Census Bureau projects that by 2076 there will be fewer families with children and working-age adults, and far more seniors—the inverse of the demographic shift that drove suburbanization. Climate change and new technologies like driverless cars will also force adaptation.
US history shows we can reorganize with extraordinary dynamism. Cities have evolved from tiny outposts to leading metropolises, then receded due to suburbanization and de-industrialization, and recently revived with younger generations. The coming transformations may not be as physically dramatic, but they require equally monumental cultural and political shifts in housing policy.
YIMBY Reforms Are Necessary but Not Sufficient
The “yes in my backyard” (YIMBY) movement has persuaded states and localities to roll back restrictive policies that prevent building enough homes. More than a dozen states, including California, have passed laws allowing accessory dwelling units (ADUs) on residential lots, and many have laws permitting denser housing like townhomes and small apartment buildings. M. Nolan Gray, senior director of legislation and research for California YIMBY, told Vox, “I suspect it’s just a matter [of time] before the rest do the same.” He predicts that “detached single-family zoning is dead” and that by 2076, typical lots in non-HOA suburbs will have at least a second unit.
However, housing reformers must also revive government’s role in shaping communities through big-picture planning. Robert Goodspeed, an associate professor of urban planning at the University of Michigan, said, “I think that the YIMBY movement has completely missed the importance of planning. Even if we repealed all zoning, it still doesn’t realize a well-designed, well-planned community that has high quality of life.”
Suburban Retrofit and Mixed-Use Development
By 2076, suburbs like La Mirada, California, could see small cottages (ADUs), subdivided houses, triplexes, fourplexes, and small apartment buildings integrated among single-family homes. Some houses could become shared senior homes. With the overall US population plateauing, regions like Greater Los Angeles might house millions more without pushing development into deserts or fire-prone hills, as two to three times more people live per acre. Shared driverless cars could free up parking space for better uses.
The hard wall between home and commerce mandated by zoning could soften, with neighborhood groceries, clinics, co-working spaces, and bike repair shops operating in residential areas. Aging malls and strip malls could be converted into mixed-use pocket neighborhoods. Gray notes that communities are rapidly repealing parking minimums, allowing parking lots to be redeveloped into housing.
The Need for Coherent Urban Planning
Failures like aimless winding streets and nightmare commutes stem from both excessive regulation and absence of coherent planning. Alain Bertaud, former principal urban planner at the World Bank, said, “You have to ensure that every neighborhood is connected to another. The market does not provide that. The job of the planner is to get involved much less in what is private, and much more in what is public.”
Street design is crucial for densification: a connected network absorbs more residents, while dead ends concentrate traffic. Gray calls for abolishing zoning and freeing planners for more useful work. States from Montana to Maine to Oregon have begun wresting zoning powers from localities, potentially leading to more unified regional planning as seen in France and Japan.
New Cities and Courtyard Blocks
In Solano County, California, the billionaire-backed startup California Forever aims to build a new city from scratch, hoping to house 400,000 people with pedestrian-centered design, mid-rise townhomes, and a traditional grid network. Gabriel Metcalf, head of planning, predicts it could have the lowest per capita car travel outside New York City. However, the project faces regulatory hurdles and cost challenges.
Alicia Pederson, founder of Courtyard Urbanist, envisions a “golden age of American city-building” with courtyard blocks common in Europe—mid-rise buildings around an interior yard—offering flexible, spacious homes with green space. This could make walkable, vibrant life accessible to more Americans.
Scenarios for 2076: Sprawl or Vibrancy
Arpit Gupta, associate professor at NYU, predicts a “dramatic increase in sprawl” due to autonomous vehicles enabling longer commutes. But Michael Manville of UCLA cautions that policy choices could lead to shared self-driving systems that reduce car ownership and increase density. Domestic migration may shift northward due to climate change, and Midwestern cities show renewed growth potential.
The future remains uncertain. A 2026 Pew Research Center survey found 44% of Americans prefer walkable areas even with smaller homes. The housing system must accommodate diverse preferences. Making room for more ways of living could reduce the scarcity that fuels national anger. As history shows, cities often surprise us—New York and Boston recovered dramatically from population loss 50 years ago. Building a less brittle housing approach with room for change is essential for America’s 300th birthday.
