The number of custom home building starts in the first quarter of 2016 jumped to 31,000, from 25,000 in the year-earlier quarter, according to National Association of Home Builders' analysis of the Census Data from the Quarterly Starts and Completions by Purpose and Design survey. Custom home builders are usually the homeowners themselves or a contractor that the homeowners hire to build the home. Therefore, this data does not include larger-scale home building projects. NAHB analyzed custom home trends this way:
The onset of the housing crisis and the Great Recession interrupted a 15-year long trend away from homes built on the eventual owner’s land. As housing production slowed in 2006 and 2007, the market share of this not-for-sale new housing increased as the number of single-family starts declined. The share increased because the credit crunch made it more difficult for builders to obtain AD&C credit, thus producing relatively greater production declines of for-sale single-family housing.
