US housing starts surge 7.2% in January to highest level in nearly a year

New residential construction in the United States jumped 7.2 percent in January to an annualized rate of 1.487 million units, the Commerce Department reported Thursday. That is the highest reading since February 2024, and it came in well above the median Wall Street forecast of 1.39 million units. The number follows a 4.8 percent increase in December, meaning housing starts have now risen in back-to-back months for the first time since mid-2023.

The timing matters. Most of the economic data landing this week has been grim: oil above $90, fertilizer prices surging, inflation expectations rising. Housing starts cut against that grain. Construction activity generates direct economic output, supports employment in trades and materials, and typically precedes a broader increase in residential investment that feeds into GDP calculations six to twelve months later.

Where the gains came from

Single-family starts rose 8.4 percent in January to an annualized rate of 1.003 million units. That crossed the one million mark for the first time since April 2024. Multi-family starts, which covers apartment buildings with five or more units, increased 4.1 percent to 484,000 units annualized. Single-family construction is the more economically meaningful number because it drives more spending per unit on materials, labor, fixtures, and landscaping than multi-family projects, which tend to cluster materials and labor costs more efficiently per square foot.

Regionally, the South accounted for most of the January gain, with housing starts there rising 11.2 percent. The South has dominated new construction for the past three years, driven by in-migration from higher-cost coastal markets, lower land costs, and generally faster permitting timelines than Northeast or West Coast jurisdictions. The Midwest posted a 6.3 percent increase. The Northeast and West were essentially flat, each moving less than one percent in either direction.

Why housing starts held up despite 7 percent mortgage rates

The 30-year fixed mortgage rate averaged 7.04 percent in the week ending January 30, according to Freddie Mac's Primary Mortgage Market Survey. That is not a favorable rate for buyers financing at full market price. It has, however, been the prevailing rate environment for over a year, and the market has adjusted. Builders have responded to elevated rates by offering mortgage rate buydowns, where they pay a portion of the buyer's interest costs for the first two to three years of the loan to reduce the effective monthly payment.

The National Association of Home Builders reported in January that 31 percent of builders were offering permanent mortgage rate buydowns as a sales incentive, up from 19 percent in January 2024. That practice effectively subsidizes the rate the buyer experiences without changing the headline mortgage rate, which means new home sales can proceed at volumes that would otherwise be suppressed by the rate environment. Existing homeowners who locked in rates below 4 percent between 2020 and 2022 are still reluctant to sell, which keeps existing home inventory tight and pushes more buyers toward new construction.

Building permits and what they suggest about February and March

Building permits, which are a forward-looking indicator of housing construction activity, rose 2.6 percent in January to an annualized rate of 1.483 million. Permits lead starts by roughly four to eight weeks, so the January permits number suggests construction activity should hold at a similar level through February and into March, barring a significant change in financing conditions or materials costs.

The Iran war introduces a genuine risk to that trajectory. Lumber prices, which had been declining since the 2021 peak, rose 9 percent in the two weeks following the Strait of Hormuz closure, partly because elevated diesel and fuel oil prices feed directly into logging, milling, and transport costs. Concrete and steel are less sensitive to oil prices than lumber, but both have supply chains that rely on diesel-powered equipment and freight. If energy prices stay above $90 per barrel through spring, materials cost inflation could erode builder margins enough to slow starts in April and May even if demand stays firm.

How economists are reading the January data in the current context

Wells Fargo's economics team published a note on Thursday describing the January housing starts report as 'the clearest positive domestic economic data point in several weeks.' The team noted that housing has historically acted as a leading indicator for broader consumer spending, because new home purchases generate demand for appliances, furniture, home improvement products, and landscaping services over the following six to eighteen months. A sustained increase in housing starts would eventually feed through to those adjacent spending categories.

The complication is that January data reflects decisions made in November and December 2024, before the Iran war began in late February 2025. Consumer sentiment has deteriorated since then. The University of Michigan's Consumer Sentiment Index fell to 57.9 in the preliminary March 2025 reading, the lowest level since November 2022, driven largely by concerns about inflation and geopolitical uncertainty. Housing sentiment surveys by Fannie Mae showed a net negative reading on 'good time to buy a house' for the 14th consecutive month in February.

The housing supply deficit that is keeping builders active

One structural fact is keeping builders in the market despite the rate environment and the geopolitical noise. The United States entered 2025 with a housing supply deficit estimated by Freddie Mac at 3.8 million units, the gap between existing housing stock and the number of units needed to meet household formation demand. That deficit built up over roughly fifteen years of under-construction following the 2008 housing crisis, when homebuilders cut capacity dramatically and never fully rebuilt it.

At the January 2025 pace of 1.487 million starts per year, the US would need approximately 25 years to close that deficit if population growth, household formation, and demolition rates held constant. They will not, but the magnitude illustrates why builders are not walking away from projects at 7 percent mortgage rates the way they might if demand were speculative rather than structural. The Commerce Department's next housing starts report, covering February 2025 data, is scheduled for release on March 19.
