New England had the largest median lot size, while the West Coast had the smallest.
The median lot size for new single-family homes in 2015 fell to a record low of less than 8,600 sf, according to analysis of the Census Bureau's Survey of Construction by the National Association of Home Builders.
There were significant regional differences in lot size. New England had the largest median lot size at half an acre, and the Pacific region had the smallest with more than half of its lots less than 0.15 of an acre. Custom home lots were not included in the analysis.
