About these numbersSources, dates and how these figures are built
New homes
U.S. Census Bureau, Building Permits Survey, 2019-01 to 2026-09; annual files 2019-2025, posted May 14, 2026; the monthly files through Sep 2026, posted Oct 27, 2026. New housing units authorized by building permits, reported plus imputed. A month is the figure in that month's file; a year is the annual file, which adds late and corrected reports, so twelve months need not add up to the year. Public domain.
