After increasing and leveling off in recent years, new single-family home size continued along a general trend of decreasing size during the third quarter of 2017. This change marks a reversal of the trend that had been in place as builders focused on the higher end of the market during the recovery. As the entry-level market expands, NAHB expects typical new home size to fall as well. According to third quarter 2017 data from the Census Quarterly Starts and Completions by Purpose and Design and NAHB analysis, median single-family square floor area was slightly lower at 2,378 square feet. Average (mean) square footage for new single-family homes declined to 2,518 square feet.
