- US multifamily housing starts fell 41.6% in May, representing a sharper drop than single-family, per Census Bureau data.
- Rising construction loan rates and stubborn material costs are undermining multifamily project pro formas, causing developers to halt new projects.
- The slowdown signals reinforced pricing power for existing multifamily owners as new supply fails to keep up with demand, supporting rents and asset values.
Rates and Costs Squeeze the Pipeline
Multifamily developers slammed the brakes in May. The US Census Bureau reported apartment starts fell 41.6% from April. GlobeSt said higher borrowing costs, pricey materials, and weak renter affordability drove the decline. Multifamily starts dropped to 284,000 units. Total housing starts fell 15.4% to 1.18M units. Single-family starts slipped just 1.9%, showing multifamily projects face greater pressure.

The Details
Housing starts totaled 1.18M in May, down from 1.39M in April. Single-family starts reached 882,000 units, slightly below April’s 899,000. Meanwhile, multifamily starts plunged from 486,000 to 284,000 units. Permits held steady at 1.41M, down only 0.7%. This suggests volatility remains concentrated in starts, not future supply.
Multifamily projects remain highly sensitive to loan costs and construction inflation. As Maor Greenberg of Spacial noted, higher rates, material costs, and affordability pressures move together. When financing stops working, developers pause multifamily projects first.
Pipeline Plateaus as Volatility Roils Multifamily
The latest figures highlight a turning point for multifamily development. Unlike industrial assets, multifamily projects have limited flexibility when costs rise. Single-family permits climbed 0.6% in May to 886,000 units. In contrast, multifamily starts acted as a pressure valve, falling sharply as borrowing costs increased. Oxford Economics said May’s decline masks a more stable housing market.
Housing completions also weakened. Total completions fell 8.1% in May to 1.31M units. Multifamily completions reached 426,000 units, down 14.2% from May 2025. As builders pull back, the industry enters the second half of 2026 with a thinner pipeline.
Why It Matters
The May decline is more than a statistical anomaly. It signals how sensitive apartment projects remain to financing costs. Sponsors relying on construction loans face growing challenges. Several lenders have also reduced their multifamily exposure, leaving developers with fewer financing options. At the same time, fewer new units could support rents and values for existing properties. Greenberg expects builders to manage a low-volume pipeline through year-end.
Oxford Economics said the weakness appears concentrated rather than widespread. Still, fewer completions will not improve renter affordability. The US already faces a housing shortage, and lower construction activity limits opportunities for developers, architects, and contractors.
What’s Next
Permits—a cleaner forward-looking metric than volatile starts—suggest the coming months will bring neither a rapid rebound nor further collapse. With building authorizations essentially flat since April, developers are in a holding pattern, watching for changes in Fed policy or a reset in construction costs.
As the fourth quarter approaches, attention will turn to completions and absorption in key Sun Belt and gateway multifamily markets. If rates stay elevated, expect cautious underwriting and a continued pause on new projects, meaning the pipeline will likely remain thin through year-end. Any pronounced shift in rates or material pricing could, however, reopen the taps overnight—so lenders, owners, and operators will be watching macro signals closely to recalibrate strategies in the second half of 2026.
