New Single-Family Home Size Trending Lower

As people use homes for more purposes including work, and with the aftermath of an unexpected virus crisis, a need for more residential space has spiked amongst homebuyers. Home size increased in 2021 as interest rates reached historic lows. But with the increase in rates in 2022, and housing affordability worsening, the demand for home size has trended lower.

Average (mean) square footage for new single-family homes stood at 2,469 square feet.
