Status

Confirmed from the Census Bureau and HUD release CB26-162, Tuesday, Oct. 20, 2026, at 8:30 a.m. Eastern. Census marks the monthly drop in starts as not statistically significant.
  • Confirmed
    September housing starts were a seasonally adjusted annual rate of 1,221,000, which is 5.2 percent below a revised August rate of 1,288,000.
  • Confirmed
    Census prints the monthly change with a margin that includes zero, so the release does not treat the drop as statistically significant.
Builders broke ground at a slower pace in September, and the government says that slowdown is inside the survey's margin of error. The Census Bureau and HUD reported a seasonally adjusted annual rate of 1,221,000 housing starts, down 5.2 percent from a revised August rate of 1,288,000.1
The release came out Tuesday, Oct. 20, at 8:30 a.m. Eastern. Permits, the paperwork for future building, were a rate of 1,400,000, which is 0.2 percent below the revised August rate. Completions, the homes actually finished, were a rate of 1,192,000. Census marks the monthly change in starts with an asterisk. The note on the release says the 90 percent confidence interval includes zero, so there is not enough statistical evidence to say the actual change is different from zero. This story does not call the month a plunge.1
The same release says September starts were also 7.4 percent below the September 2025 rate, and that comparison is marked the same way. Completions were 14.0 percent below a year earlier, and that yearly drop is not marked with the asterisk. Single-family starts were a rate of 859,000. Buildings with five or more apartments started at a rate of 349,000. Those extra figures are in the notes.1
Why it matters (Estimate). Estimate. Homes started now are a large part of the houses and apartments that come up for sale or rent later. One month inside the margin of error is not, by Census's own test, proof that building collapsed.1 A pace that is not picking up, and a count of finished homes well below last September, points to tight supply, which is what keeps prices and rents high.
The release does not say why the pace moved. The next report, for October, is scheduled for Nov. 18.

Notes

  1. 1.U.S. Census Bureau and Department of Housing and Urban Development, “Monthly New Residential Construction, September 2026,” CB26-162, for release at 8:30 a.m. EDT, Tuesday, October 20, 2026. The HTML page was re-opened for this edition. https://www.census.gov/construction/nrc/current/index.html “Privately-owned housing starts in September were at a seasonally adjusted annual rate of 1,221,000. This is 5.2 percent (±11.8 percent)* below the revised August estimate of 1,288,000 and is 7.4 percent (±11.5 percent)* below the September 2025 rate of 1,319,000.” Permits: “1,400,000. This is 0.2 percent below the revised August rate of 1,403,000.” Completions: “1,192,000. This is 2.2 percent (±10.8 percent)* above the revised August estimate of 1,166,000, but is 14.0 percent (±11.1 percent) below the September 2025 rate of 1,386,000.” Single-family starts 859,000. Five-or-more-unit starts 349,000. Single-family permits 845,000. Five-or-more-unit permits 503,000. The PDF, https://www.census.gov/construction/nrc/pdf/newresconst.pdf , was downloaded for this edition but the text did not extract. The economy desk's morning read of that PDF gives the asterisk note: “The 90 percent confidence interval includes zero. In such cases, there is insufficient statistical evidence to conclude that the actual change is different from zero.” The same read says the October report is scheduled for November 18, 2026. The HTML page confirms the asterisk on the monthly starts change. The explanatory note and the Nov. 18 line are the desk's PDF read.

What is still unknown or disputed

  • The release does not give a cause for the monthly change.
  • Regional totals were not pulled into this story.
  • August starts were revised. The first published August figure is not restated here beyond the revised 1,288,000 in this release.
