US Housing Starts, August 2026 — Estimated 2.6% Monthly Decline Not Statistically Significant; 27.1% Annual Fall in Completions Is
August 2026 starts: 1,275,000 annual rate, 2.6% below July; the 90% interval for that change (-14.6% to +9.4%) includes zero. Completions fell 11.9% from July and 27.1% on the year, both significant.
The headline number and its interval
Census and HUD put August housing starts at 1,275,000 (seasonally adjusted annual rate), 2.6 percent below July — but the release prints that change as "2.6 percent (±12.0 percent)*", and the asterisk means the 90 percent confidence interval includes zero.[1]
The release's own rule: "If a range does not contain zero, the change is statistically significant. If it does contain zero, the change is not statistically significant; that is, it is uncertain whether there was an increase or decrease." By that rule the estimated decline in total starts and the estimated 7.6 percent rise in single-family starts (±14.0 percent) are not statistically significant at the 90 percent level: the data do not establish the direction of the actual changes.[1]
What did move: completions
Completions fell to a 1,128,000 rate: 11.9 percent (±9.7 percent) below July and 27.1 percent (±8.9 percent) below August 2025. Neither interval includes zero, so both declines are statistically significant.[1]
From January–August 2026 compared with January–August 2025 (not seasonally adjusted), completions were 12.9 percent (±5.2 percent) lower — a statistically significant decline — while the 1.0 percent (±3.7 percent) change in starts was not statistically significant (this page's reading of Tables 3b and 5b).[1]
Permits and the backlog
Building permits were at a 1,394,000 rate, 2.7 percent below July and 3.5 percent above a year earlier. Permits are counted from a non-probability sample and are not given sampling intervals.[1]
Units authorized but not yet started reached 280,000 at the end of August, 12.9 percent (±7.1 percent) above August 2025.[1]
Reading one month
The release cautions: "It may take three months to establish an underlying trend for building permit authorizations, six months for total starts, and six months for total completions." It also notes that preliminary estimates of permits, starts and completions are revised 3.8 percent or less on average.[1]
