Housing starts fall 5.2% to 1.22 million as 43% of builders cut prices, the most since 2020

US housing starts fell 5.2% in September to a seasonally adjusted annual rate of 1,221,000, from a revised 1,288,000 in August, the Census Bureau reported on Tuesday. Starts were 7.4% below September 2025. Separately, the National Association of Home Builders says 43% of builders cut prices in October, the highest share of the 2020 to 2026 period.

The number behind the number

Census prints a margin of error of plus or minus 11.8% on the monthly change. A 5.2% decline is well inside that band, so by itself it is not proof that building fell. The better evidence is what sits around it:

Single-family permits, the forward-looking piece, fell 4.0%. Completions are 14.0% below a year ago, which means fewer new homes are about to reach the market even as builders struggle to sell the ones they have.

Builders are paying to sell

The NAHB/Wells Fargo index fell three points to 29 in October. Buyer traffic fell five points to 18. On pricing, 43% of builders cut prices, the average cut stayed at 6% for a seventh straight month, and 65% used sales incentives, the 19th month in a row above 60%. MarketWatch frames the traffic reading as a 14-year low.

Reading the revisions

August was revised to 1,288,000, so the September drop is measured from a higher base than first reported. On the year, starts are down 7.4% while permits are down only 3.0% (1,400,000 versus 1,444,000). Permits have fallen less than starts, which says builders still hold permission to build that they are choosing not to use. That is a different problem from regulators blocking construction: it is a decision to wait until homes can be sold without a 6% discount.

Multifamily is the quieter piece. Census puts starts in buildings of five or more units at 349,000 and permits for the same type at 503,000, a gap of about 154,000 units a year of approved apartments not yet started. For landlords and lenders, those unstarted projects are a pipeline that can switch on if financing eases.

Who it hits

• Framing and trades subcontractors. Starts are their order book. A builder that cuts a house price 6% tends to push the squeeze down to its subs. We hold records of 34,694 independent roofing, 40,729 HVAC, 27,975 plumbing and 25,380 electrical businesses; our HVAC playbook covers how to hold margin when new-build work thins out and repair work becomes the base.
• Lumber, concrete and appliance suppliers. Fewer starts means smaller orders about 60 to 90 days out.
• Buyers closing now. Builder incentives such as rate buydowns are the one place a buyer has leverage while resale inventory stays thin. Our Freddie Mac rate breakdown has the monthly-payment math at 7.40%.

CNBC's report on the same data headlines it as a housing market in a "deep freeze" just as the Fed weighs more hikes. Our coverage of the Fed's stance is in this earlier story. Mortgage rates, not demand for shelter, remain the constraint.
