Over the past decade, we've watched the average size of newly built single-family homes in the U.S. decrease from 2,700 to 2,400 square feet—even as price per square foot has jumped by about 72%. By 2025, a quarter of all new single-family homes sold measured under 1,800 square feet, compared to just one in six a decade ago. At the same time, larger homes of 3,000 square feet or more are becoming less common, now making up only one in five new builds (down from about one in three). Builders are turning to more compact designs as a practical response to rising costs for land, labor, and materials, aiming to keep new homes attainable despite mortgage rates hovering around 6% to 7%.
For many buyers—especially those looking for their first home or working within a budget—these smaller footprints can make homeownership more accessible by reducing down payments and monthly costs. However, it’s important to be aware that the increase in price per square foot means overall affordability remains a challenge. With our combined sixty years of real estate experience in the San Ramon Valley and extensive involvement with both the California and National Associations of Realtors, we’ve seen firsthand how these trends impact buyers locally and nationally. As always, understanding the numbers and the bigger picture is key to making informed decisions in today’s housing market.
