How U.S. Homes Grew and Why Affordability Shrunk: A Look at the 1970s, 1980s, and Today
How U.S. Homes Grew and Why Affordability Shrunk: A Look at the 1970s, 1980s, and Today
Walk into a renovated ranch or split-level from the 1970s or 1980s, and it immediately feels more compact than a modern home. That feeling is justified. Over the last fifty years, houses in the United States have nearly doubled in size while household incomes have barely budged in comparison. This widening gap between how big homes have become and how slowly wages have risen is a central reason ownership is harder to achieve today.
Homes in the 1970s
In the mid-1970s, the typical new home averaged about 1,600 square feet. Layouts were straightforward and focused on practicality rather than luxury. Families lived with smaller kitchens, modest storage, and traditional room separation because expectations were simpler and budgets were tighter. Homebuilding was oriented toward utility, affordability, and a middle-class buyer who did not demand extensive amenities.
The Shift in the 1980s
By the mid-1980s, home sizes had increased to around 1,800 square feet. This period introduced early versions of open-concept living along with expanded kitchen and living areas. Builders also began adding attached garages, bonus rooms, and more specialized spaces as suburban growth took off. Rising dual-income households and improving consumer credit contributed to a mindset that more space was both desirable and increasingly achievable.
To summarize the difference between the two decades:
- 1970s homes emphasized simplicity and low cost.
- 1980s homes added space, convenience, and early luxury features.
- Consumer expectations started shifting upward, influencing how builders operated.
Today’s Homes
Homes built in the 2020s typically fall between 2,350 and 2,500 square feet and come with features that would have been considered upgrades in earlier generations. The standard wish list now includes large owner’s suites, walk-in closets, spacious kitchens with islands, and flexible rooms that serve as offices or guest spaces. Higher ceilings, larger garages, and outdoor living areas also contribute to the modern idea of what a “normal” home should offer.
What Larger Homes Mean for Affordability
As home sizes grew nearly seventy percent since the 1970s, incomes increased far more slowly. Larger homes naturally require more materials, more labor, and more land, which raises the cost of construction and pushes prices upward for buyers. Affordability becomes strained when the baseline product in the market shifts from modest and functional to expansive and amenity-rich.
A second pressure point is land. In the 1970s, land near growing cities was cheaper and more abundant, which allowed builders to sell small starter homes at accessible prices. Today, land is significantly more expensive and zoning rules often require larger lots than many buyers truly need. This combination forces builders to create larger homes at higher margins simply to cover land and development costs.
Cultural expectations amplify these pressures. Over time, Americans began viewing certain upgrades as non-negotiable features. Big kitchens, large closets, and spacious bathrooms became the standard rather than the exception. This shift helped eliminate the traditional starter home. Only a small share of new homes built today are under 1,400 square feet, a size that was once common in nearly every market.
Here are the key impacts on today’s buyers:
- Fewer small, attainable homes are being produced.
- The cost of land and regulation pushes builders toward larger, more expensive products.
- Entry-level buyers face limited options and higher barriers to ownership.
Where This Leaves the Market
Affordability did not erode solely because construction costs rose. It eroded because the definition of a “standard” home fundamentally changed. Earlier generations bought smaller, simpler homes, and those homes were intentionally designed to fit middle-class incomes. Today, the baseline product has grown beyond what many first-time buyers can comfortably afford.
The path back toward affordability requires more than just adding supply. It requires enabling builders to create smaller homes through updated zoning, smaller lots, and more flexible housing types such as cottage courts, townhomes, and missing-middle developments. Many households also show a growing interest in manageable, lower-maintenance homes, which suggests that demand for smaller options is strong if policies and economics allow them to be built.
Final Thoughts
Homes in the 1970s and 1980s were compact, practical, and accessible to average families. Modern homes offer far more features, but that expansion in size and amenities has come at the cost of affordability. If homeownership is to become widely attainable again, the market must shift toward building smaller, thoughtfully designed homes that align with what typical households can realistically afford.
