U.S. housing starts fell 5.2 per cent in September to a seasonally adjusted annual rate of 1,221,000, the Census Bureau and the Department of Housing and Urban Development said on Tuesday 20 October, a decline smaller than the survey's own margin of error.
The National Association of Realtors, the real estate agents' trade group, said the same day that its pending home sales measure fell 7.3 per cent. The two releases measure different things, builders breaking ground and buyers signing contracts. Only one of them comes with a warning that the move may not be real.
What did Census report for September?
A drop it cannot distinguish from zero. Starts of 1,221,000 compare with a revised 1,288,000 in August and 1,319,000 in September 2025, according to the Census release. The monthly decline of 5.2 per cent carries a margin of error of plus or minus 11.8 per cent; the annual decline of 7.4 per cent, plus or minus 11.5 per cent. Census marks both with an asterisk, its sign that the true change could be zero. Single-family starts were 859,000, down 4.6 per cent from a revised 900,000, also within the margin.
Permits are steadier, because they count approvals rather than a sample of building sites. Total permits were 1,400,000, 0.2 per cent below August's revised 1,403,000 and 3.0 per cent below the 1,444,000 of September 2025. Single-family permits fell 4.0 per cent to 845,000. Completions were 1,192,000, up 2.2 per cent on the month but 14.0 per cent below a year earlier, a fall Census does not flag as uncertain.
| Measure (seasonally adjusted annual rate) | September 2026 | Change from August | Change from September 2025 | |---|---|---|---| | Housing starts | 1,221,000 | -5.2% (±11.8%) | -7.4% (±11.5%) | | Single-family starts | 859,000 | -4.6% (±10.0%) | not given | | Building permits | 1,400,000 | -0.2% | -3.0% | | Single-family permits | 845,000 | -4.0% | not given | | Completions | 1,192,000 | +2.2% (±10.8%) | -14.0% (±11.1%) |
Where did buyers pull back?
Everywhere. Pending home sales, which count signed contracts on existing homes, fell 7.3 per cent from August and 11.3 per cent from September 2025, according to the NAR release. Every region fell on both measures. NAR's index stood at 66.0, where 100 equals the average level of contract activity in 2001.
| Region | Change from August | Change from September 2025 | |---|---|---| | Northeast | -4.2% | -9.4% | | Midwest | -6.5% | -8.7% | | South | -8.2% | -12.0% | | West | -9.2% | -15.0% |
Lawrence Yun, NAR's chief economist, gave a plain cause. "Market conditions weakened in September due to fast-rising mortgage rates," he said. He added that "mortgage rates have already risen much more than the Federal Reserve's short-term interest rate hikes," and that "mortgage rates could be topping out."
What does the pairing tell us?
That buyers have stepped back faster than builders. Contracts fell in every region, while starts fell by less than their margin of error and permits barely moved. Total permits of 1,400,000 sat about 179,000 above the starts rate (this publication's arithmetic). That gap does not mean a surge is coming: permits can lapse unused, and builders time starts to financing and sales. It does mean September was not a collapse in approvals. That is our reading of the two releases, not either agency's.
Yun's other point deserves attention. "Despite the difficulty of obtaining a mortgage, the limited number of distressed properties is ensuring steady home prices," he said, and "buyers and sellers may simply be holding back until mortgage rates move favorably." That describes a market adjusting on volume rather than price. This publication has tracked the payment side of that squeeze in its report on monthly mortgage costs.
What to watch next
Census publishes October starts on 18 November. A second monthly fall would start to look like a trend rather than sampling error; one month is not. NAR's next contract reading will show whether Yun is right that rates are near a peak. If he is not, contracts lead and starts follow them down.
Housing starts, permits, completions, margins of error and revisions come from the Census Bureau and Department of Housing and Urban Development release "Monthly New Residential Construction, September 2026" (CB26-162), 20 October 2026, which also gives the 18 November date for the next release. Pending home sales figures, regional changes, the index base and the Lawrence Yun quotations come from the National Association of Realtors release "Pending Home Sales Decreased 7.3% in September," 20 October 2026; the 66.0 index level is from the graphic accompanying that release. Some reports described the index level as a record low; NAR's release does not say so, and we have not repeated it. The gap between permits and starts is this publication's arithmetic. The analysis is our own.
