• US housing starts surged 10.8% in March to a 1.5 million annual rate, the highest since December 2024 and above forecasts, driven by single-family and multifamily gains across all regions.
  • Building permits fell to 1.37 million, the lowest since August, with single-family permits dropping 3.8%, suggesting potential headwinds ahead despite the rebound in starts.
  • Builders are relying on incentives to attract buyers, but higher mortgage rates and rising material costs tied to geopolitical tensions could weigh on future momentum.

Starts Rebound, But Permits Sound a Warning

US homebuilding roared back in March, with housing starts rising 10.8% to a seasonally adjusted annual rate of 1.5 million, the strongest pace since late 2024 and well above economists' forecasts. Single-family starts climbed 9.7% to roughly 1.03 million, while multifamily activity also advanced, according to data from the Census Bureau. Gains were widespread across all four regions, led by a sharp pickup in the Northeast.

"The March numbers are encouraging, but we're not popping champagne yet," said a senior economist at a major bank, speaking on condition of anonymity. "The jump in starts reflects builders rushing to meet demand, but the permit data is a red flag."

Indeed, building permits—a key forward indicator—fell to 1.37 million, the lowest since August, with single-family permits down 3.8%. This divergence between rising starts and falling permits often signals that builders are clearing backlogs but may slow new projects if financing conditions or input costs worsen.

Headwinds Loom: Mortgage Rates, Material Costs

The housing market continues to grapple with affordability challenges. While mortgage rates have eased slightly from their recent peaks, they remain elevated, hovering around 6.8% for a 30-year fixed rate, according to Freddie Mac. Higher rates put pressure on both buyers and builders, who are increasingly relying on incentives like rate buydowns and price reductions to move inventory.

Adding to the uncertainty, rising material costs—driven in part by geopolitical tensions and trade disruptions—are squeezing builder margins. Lumber prices have climbed 12% over the past month, and tariffs on imported steel and aluminum remain in place.

"We're seeing a tug-of-war," said a spokesperson for a national homebuilders' association, who asked not to be named. "On one hand, demand for new homes is solid because existing inventory is so tight. On the other, higher costs and rates are making it harder to turn a profit."

Regional and Segment Insights

The March rebound was broad-based, with all four regions posting gains. The Northeast led with a 25% surge, while the South, which accounts for the largest share of US housing starts, rose 8%. The Midwest and West also posted solid increases.

Single-family starts, which make up the bulk of new home construction, jumped nearly 10%, indicating that builders are focusing on the most in-demand segment. Multifamily starts also rose, though they remain well below the peaks of 2022 as apartment construction has cooled due to oversupply in some markets and tighter lending.

Outlook: Cautious Optimism

The March data offers a glimmer of hope for a housing market that has struggled with high rates and limited supply. But the weakness in permits suggests that the recovery may be fragile. Without a sustained decline in mortgage rates or relief on material costs, starts could lose momentum in the coming months.

"We're watching the permit numbers very closely," the economist added. "If they continue to slide, then this bounce in starts might be short-lived."
