National Association of Realtors findings
Home buyers will have a harder time finding a big yard, as lot sizes remain near record lows, according to the U.S. Census Bureau. Among sold properties in 2017, the median lot size for a new, detached single-family home was one-fifth of an acre, or 8,560 square feet. Median lot sizes fell below 8,600 square feet in 2015 for the first time since the bureau started recording such data.
Lot sizes vary regionally, and the nation’s largest tend to be in New England. More than half of single-family spec homes in the area are built on lots exceeding 0.4 acres. New England is known for having stricter zoning regulations than other parts of the nation, which requires builders to keep lower densities for construction.
On the other hand, the Pacific region, including California, Washington, Oregon, Hawaii, and Alaska, has some of the tiniest lots in the nation—half of which are smaller than 0.15 acres.
