Of the roughly 876,000 single-family homes started in 2018, 22.6% included decks, according to NAHB tabulation of data from the Survey of Construction (SOC, conducted by the U.S. Census Bureau and partially funded by HUD). This is down over a full percentage point from he 23.8% recorded a year earlier.
From 2005 to 2008, the share of new homes with decks was consistently over 25%—as high as 27% in 2007 and 2008. In 2009, the share dropped to under 25% and continued to decline, reaching a low point of 22.2% in 2012. The 2018 figure of 22.6% is the lowest the share of new single-family homes with decks has been since 2013.
