US Construction Spending Climbs 0.4% in April, Led by Single-Family Homebuilding
Why It Matters
Construction spending data reflects the health of the broader economy, and for states like Idaho — where residential and commercial development have been central to recent growth — the national trend offers useful context for local builders, buyers, and policymakers alike.
What Happened
Total U.S. construction spending rose 0.4% in April, surpassing economist forecasts of a 0.2% gain, according to figures released by the Commerce Department’s Census Bureau. The March figure was revised downward to a 0.2% increase from a previously reported 0.6% rise.
On a year-over-year basis, construction spending was up 0.9% in April. Private construction outlays advanced 0.4%, building on a 0.2% gain the prior month. Residential construction investment climbed 0.8%, with spending on new single-family projects rising 1.4%. Multi-family housing spending, however, declined 0.3%.
Despite the headline gain, headwinds remain. The 30-year fixed mortgage rate averaged 6.53% as of last week — a nine-month high and up sharply from 5.98% at the end of February. Builders are contending with elevated borrowing costs, tariff-driven material expenses, and ongoing land and labor shortages, all of which are limiting new groundbreakings.
By the Numbers
- +0.4% — Overall construction spending increase in April
- +1.4% — Spending growth on new single-family housing projects
- +4.8% — Jump in federal government construction outlays, attributed in part to detention facility construction
- 6.53% — Current average 30-year fixed mortgage rate, per Freddie Mac data
- Nine consecutive quarters — Length of contraction in private non-residential construction spending, even as data center investment tied to artificial intelligence has grown
Federal Spending Drives Public Construction Gains
Public construction investment rose 0.4% in April, following a 0.2% gain in March. State and local government spending edged up just 0.1%, while federal construction outlays jumped 4.8% — a surge analysts attribute largely to the ongoing expansion of immigration detention facilities as the Trump administration continues its enforcement push along the southern border.
Private non-residential construction — which includes power plants and manufacturing facilities — slipped 0.2% in April. That category has now contracted for nine straight quarters, even as investment in data centers supporting artificial intelligence infrastructure has surged.
Zoom Out
The April report lands as the housing market faces a complicated set of pressures. Mortgage rates have climbed alongside broader inflation concerns, dampening buyer demand and making it harder for builders to commit to new projects. For a region like the Mountain West, where population growth has outpaced housing supply for years, any slowdown in residential construction carries real consequences for affordability and inventory.
The recent U.S.-China trade agreement targeting $17 billion in annual agricultural purchases underscores the larger economic uncertainty facing builders and developers, as tariff policy continues to affect construction material costs. Similarly, broader questions about federal fiscal direction — including ongoing government spending debates — are shaping the climate for both public and private construction investment.
What’s Next
Economists and industry observers will be watching whether single-family housing momentum can persist through the summer months despite elevated mortgage rates. If borrowing costs remain near nine-month highs, builders may pull back on new project starts, potentially tightening inventory further in already supply-constrained markets.
Federal construction activity is likely to remain elevated in the near term given the administration’s continued emphasis on border enforcement infrastructure. Whether private non-residential construction can break its nine-quarter contraction streak may depend heavily on whether tariff pressures ease and broader inflation cools in the months ahead.
