Northeast Drives Multifamily Starts as West Retrenches

According to Globe St, the US multifamily pipeline is no longer moving in lockstep. Realtor.com’s Q1 2026 rental housing report shows a widening regional divide as developers continue breaking ground in the Northeast and South while the West slows sharply after several years of aggressive apartment construction.

Nationally, multifamily activity remains elevated compared with pre-pandemic norms, even as deliveries cool and some markets struggle with rent softness. For investors and lenders, the latest numbers reinforce that market selection — not just asset class exposure — will likely define performance over the next several quarters.

A National Pipeline Still Above Normal

The US had roughly 684,000 multifamily units under construction in Q1 2026, according to Realtor.com. That total fell 10.6% year over year from approximately 765,000 units, but it still sits 11.4% above the average first-quarter level recorded between 2017 and 2019.

Developers also accelerated new projects despite a slower delivery pace. Multifamily starts climbed 19.7% annually to a seasonally adjusted annualized rate of 462,000 units, or 21.3% above pre-pandemic averages. Meanwhile, completions dropped 17.5% year over year to 470,000 units, though they remain 23% higher than historical norms.

The combination suggests the current apartment supply wave is moderating, not disappearing. Projects already underway continue feeding inventory into the market even as developers selectively restart construction in growth regions.

Northeast Multifamily Starts Surge

The Northeast posted the strongest construction momentum in the country. Multifamily starts jumped from 58,000 units in Q1 2025 to 105,000 units in Q1 2026 — an 81% increase and more than double the region’s 2017–2019 average of 52,000 units, per Realtor.com.

Completions in the region climbed 42.1% year over year to 108,000 units, while units under construction reached 144,000, still 9.1% above pre-pandemic levels despite a modest annual decline. That growing pipeline is already influencing pricing in several major metros.

Boston rents fell 2.9% annually in April, while Philadelphia rents declined 1.5%, according to Realtor.com data. New York remained an outlier, however, posting a 1.1% rent increase despite broader regional softness.

The South continues to lead the nation in total apartment volume, though the market appears further along in its supply cycle. The region had 279,000 units under construction in Q1, down 11.1% from a year earlier but still nearly 23% above pre-pandemic averages.

At the same time, Southern multifamily starts surged 40.2% year over year to 230,000 units, signaling developers remain confident in long-term population and employment growth across the region. Completions, however, fell 26% to 199,000 units, potentially creating a temporary absorption window before another wave of deliveries arrives.

The Midwest Keeps Expanding Cautiously

The Midwest remains a smaller multifamily market overall, but supply levels continue running above historical norms. Units under construction declined 5.4% year over year to 87,000, though that figure still sits roughly 21% above the region’s pre-pandemic baseline.

Starts fell 12.5% to 49,000 units, while completions slipped just 1.6% to 63,000 units. Even so, completions remain more than 50% above 2017–2019 averages.

That measured growth is helping many Midwestern markets avoid the steep rent corrections seen in oversupplied Sun Belt metros. Realtor.com data shows Kansas City and Pittsburgh among the few large US markets still recording annual rent growth above 3%.

The moderation in new supply also comes as national apartment occupancy rates stabilize near long-term averages after several quarters of elevated deliveries and concession-heavy leasing.

The West Falls Below Pre-Pandemic Norms

The West posted the weakest multifamily performance in the country and became the only region where activity fell below pre-Covid benchmarks.

The region had 174,000 units under construction in Q1 2026, down 14.7% year over year and 4.4% below its pre-pandemic average. Starts dropped 28% annually to 77,000 units — roughly one-third below 2017–2019 levels — while completions plunged 37.9% to 100,000 units.

That pullback comes while many Western markets are still experiencing rent declines. Los Angeles rents fell 1.7% year over year in April, Denver dropped 3.4%, and Phoenix declined 4.2%, according to Realtor.com.

Still, some coastal tech markets are beginning to separate from the broader regional trend. San Jose posted a 1.3% annual rent gain while San Diego, San Francisco, and Seattle continued seeing declines, highlighting how constrained new supply can quickly tighten fundamentals.

Why It Matters

The apartment market is increasingly becoming a regional story rather than a national one. Developers continue adding supply in high-growth Northeast and Southern markets even as rent growth weakens, while Western builders are retreating after years of heavy construction.

For institutional investors, that divergence could reshape underwriting assumptions around lease-up timelines, concessions, and rent growth over the next several years. Markets with sustained deliveries may continue favoring renters, while areas with constrained pipelines could regain pricing power faster once existing inventory is absorbed.

Forward-looking projections from Realtor.com reinforce that split. By Q1 2027, rental housing stock growth is expected to reach 1.1% in the Northeast and 0.9% in the South, compared with just 0.7% in both the Midwest and West.

What’s Next

The next phase of the multifamily cycle will likely hinge on how quickly markets absorb the current delivery wave. Sun Belt metros including Austin, San Antonio, Nashville, and Tampa are still posting rent declines between 4% and 5% as concessions and lease-up pressure persist.

At the same time, slowing construction in the West could eventually tighten fundamentals if demand stabilizes. Developers, lenders, and equity partners will increasingly focus on local supply pipelines rather than broad national rent averages as they evaluate where the next apartment recovery takes hold first.
