Home construction weakened across the board in September, according to data released Tuesday morning, as mortgage rates above 7% continued to price buyers out and left builders cutting prices at the fastest clip of the decade.
Privately-owned housing starts ran at a seasonally adjusted annual rate of 1,221,000 last month, the Census Bureau and the Department of Housing and Urban Development reported. That is 5.2% below the revised August estimate of 1,288,000 and 7.4% below the September 2025 rate of 1,319,000. Single-family starts fell to 859,000, down 4.6% from a revised 900,000 in August.
Permits Signal No Rebound
The forward-looking permit data offered little comfort. Building permits were authorized at an annual rate of 1,400,000 in September, 0.2% below the revised August rate of 1,403,000 and 3.0% below a year earlier. Single-family authorizations — the cleanest read on what builders intend to put in the ground — dropped 4.0% to 845,000 from a revised 880,000. Multifamily permits, for buildings with five units or more, came in at 503,000, well above the 349,000 annual rate of multifamily starts.
Completions were the one bright spot, rising 2.2% to 1,192,000, though that figure sits 14.0% below September 2025 as the pandemic-era multifamily pipeline empties out.
A caution worth noting: the Census Bureau flags a ±11.8 percentage point confidence interval on the monthly starts decline, meaning the drop is not statistically significant on its own. The agency advises that it takes roughly six months to establish an underlying trend in total starts. The direction of travel across permits, sentiment and rates, however, all points the same way.
Builders Are Cutting Prices
The National Association of Home Builders reported Monday that its Housing Market Index fell three points in October to 29, the lowest reading since June 2012. Any figure below 50 means more builders rate conditions poor than good. All three components declined: current sales conditions slipped two points to 33, sales expectations for the next six months fell five points to 32, and prospective buyer traffic dropped five points to 18.
"Mortgage rates have climbed well above 7% in recent weeks, and higher gas prices and inflation have further weakened buyer traffic across much of the country," said NAHB Chairman Bill Owens.
NAHB Chief Economist Robert Dietz added that "demand persists, but higher mortgage rates, elevated construction costs and weaker consumer confidence are keeping more buyers on the sidelines."
Forty-three percent of builders cut prices in October, the highest share in the 2020–2026 period, with the average reduction holding at 6% for a seventh straight month. Sixty-five percent offered some form of incentive, the 19th consecutive month above 60%.
Rates Are the Binding Constraint
Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed rate at 7.40% in its October 15 reading, unchanged on the week and up from 6.27% a year ago. The 15-year averaged 6.71%, against 5.52% last October.
That is the arithmetic squeezing the sector. The Federal Reserve's target range stands at 3.75%–4.00% after September's increase, and the inflation data that has driven long rates higher is not cooperating: Brent crude for December delivery traded near $111.70 a barrel Tuesday, its highest level since May, on Middle East supply risk, CNBC reported. Prediction markets Kalshi and Polymarket showed roughly 86% to 88% odds of no change at next week's October 27–28 FOMC meeting as of Monday, with pricing pointing instead to a December move.
For housing, the distinction matters less than the level. Until the 30-year retreats below 7%, the construction data is likely to keep reading the way September's did.
