Based on CoreLogic public records data for single-family homes and townhouses, home builders are building larger homes on smaller lots. The median size of newly built homes is 2,300 square feet, while the median lot size decreased from 8,250 square feet in 1990 to 6,970 square feet in 2016. There are several reasons for this trend, CoreLogic speculates, including demand from certain buyers for larger homes and builders being driven by higher profits. Larger homes can bring in more revenue and smaller lots can keep costs down.
