More than two-thirds (67) of new single-family detached homes sold in 2021 were built on lots smaller than one-fifth of an acre, possibly due to unprecedented lot shortages in the midst of a nationwide homebuying boom.
The most dramatic shift in lot size distribution during the last decade took place at the lowest end, with lots under 0.16 acres increasing their share from 28% in 2011 to 39% in 2021.
The latest SOC data show that 67% of all new single-family detached homes sold in 2021 were occupying less than 1/5 of an acre. Going back to 1999, when the Census started tracking these data, the share was 46%. A persistent shift towards smaller lots, however, is a more recent phenomenon. The share of lots under one fifth of an acre was fluctuating around 48%, never crossing the 50% mark, until 2011.
