Builders finished homes at a seasonally adjusted annual rate of 1,192,000 in September, the Census Bureau says. That is up 2.2% from a revised August pace of 1,166,000, but 14.0% below the 1,386,000 rate of September 2025. Finished homes are the ones that actually reach buyers and renters, so the yearly drop is the number that matters for housing costs.
Completions edged up in a month and sit far below last year
The monthly gain looks better than it is. Census puts the margin of error on the one-month change at plus or minus 10.8%, which is wider than the 2.2% rise itself. The 14.0% drop from a year ago carries a margin of plus or minus 11.1%, so that decline is the firmer finding.
A seasonally adjusted annual rate takes one month’s pace, smooths out normal seasonal swings and projects it over twelve months. It does not mean builders finished 1.19 million homes in September alone. The yearly comparison uses the same measure for September 2025, so the two figures line up.
Single-family completions, the finished houses most people picture, ran at 840,000, down 2.4% from a revised August rate of 861,000. Buildings with five or more units, mostly apartments, ran at 339,000. Together those two pieces make up nearly all of the national total.
For anyone planning a move, a downsizing sale or a purchase for a grandchild, the practical meaning is supply. A year ago builders delivered about 194,000 more homes and apartments on an annual basis than they did in September. A thinner flow of new places to buy or rent leaves fewer options in the market.

The South finished half the nation’s new homes
The Census release tables split September completions by region. The South led at 604,000, followed by the West at 317,000, the Midwest at 185,000 and the Northeast at 86,000. Single-family completions ran in the same order: 472,000 in the South, 200,000 in the West, 113,000 in the Midwest and 55,000 in the Northeast.
The South therefore accounted for roughly half of all new homes finished nationwide. Retirees weighing a move to the South are shopping where most of the new construction is landing. In the Northeast, 86,000 is a small pool of new product for a region with many older homes.
Regional numbers are more volatile than the national total because they rest on smaller samples. Census says its preliminary estimates of permits, starts and completions are revised by 3.8% or less on average, and August’s completions were already revised in this release. The October figures are due November 18.
Homes still under construction, and the starts behind them
Crews had 1,280,000 units under construction at the end of September, including 587,000 single-family homes, according to the Census tables. The National Association of Home Builders (NAHB) calculates that total is down 3.3% from a year earlier, with single-family units under construction down 2.8%.
Another 279,000 units had building permits but no construction start, 151,000 of them single-family. That backlog of approved projects is the pool that the next several months of completions draw from. If builders stay cautious, the pool does not refill quickly.
Starts, the first step in the pipeline, also fell. Builders began homes at a 1,221,000 annual pace, down 5.2% from August, and single-family starts of 859,000 were the lowest in a year, NAHB says. Fewer starts today mean fewer completions several months from now.
Permits, the earliest step, held steadier. Local governments authorized homes at a 1,400,000 annual rate, down 0.2% from August and 3.0% below September 2025, with 845,000 of them single-family. Starts were down 7.4% from a year earlier, from 1,319,000, though that estimate carries a margin of plus or minus 11.5%.
NAHB blames the single-family weakness on persistent affordability pressures, including higher financing and building material costs and ongoing labor shortages. The trade group also counts completions of buildings with five or more units as down 20.4% from a year ago, and single-family completions as down 11.0%.
What slower construction does to rents and carrying costs
The steeper drop is in apartments. Apartment completions are the new supply that competes for renters, so a 20.4% decline matters to anyone paying rent, and to families helping an adult child or grandchild who does. The single-family decline matters most to people trying to buy or sell.
Housing costs are more than the sticker price or the rent. Property taxes, insurance, utilities and heating bills take the biggest bite out of fixed incomes when prices stay firm. Several state and federal programs help cover those costs, including property-tax breaks and heating assistance, and most require the household to apply.
The Census report does not forecast rents or prices, and builders have not said when completions will turn back up. What the numbers show is a pipeline that is narrower than it was a year ago at every stage, from permits to starts to finished homes. The next release will show whether September’s small monthly gain holds.
Will fewer finished homes raise housing costs for fixed incomes?
Fewer new homes and apartments leave rents, property taxes and utility bills with little room to ease, and those are the costs that keep climbing on a fixed income. The Census numbers show the supply side. They do not show which help programs a household has left unclaimed.
The Benefits Checklist scans 11 benefit programs, including property-tax breaks, heating help and SNAP, and lays out the 2026 income limits beside a 50-state phone directory. Housing data cannot say what to do about rising costs; this kit finishes that related job, with a printable tracker for each application that comes with the download.
