A sharp split is emerging in the nation's multifamily pipeline: while the Northeast and parts of the South are gearing up for another wave of product, the West is slipping below its own historical norms even as rents there remain under pressure. For commercial real estate investors, developers and lenders, the latest rental report from Realtor.com points to a market where construction timing and geography may matter more than headline rent trends.
National Pipeline Still Elevated
The national numbers still show elevated multifamily activity compared with the pre-pandemic era, even as some projects work their way out of the system. In the first quarter of 2026, there were about 684,000 multifamily units under construction across the U.S., down 10.6% from roughly 765,000 a year earlier but still 11.4% above the average level seen in the first quarters of 2017–2019. Starts, at 462,000 units annualized, rose 19.7% year-over-year and stood 21.3% higher than the pre-pandemic Q1 average, suggesting developers are still willing to launch new projects even as completions have slowed. Completions fell 17.5% from 2025's first quarter to 470,000 units, yet that figure remains 23% ahead of pre-pandemic norms, indicating the current supply wave is not yet spent.
Northeast And South Drive The Next Wave
Underneath those national aggregates, the regional divergence is stark. The Northeast is posting the strongest construction momentum, with first-quarter multifamily starts nearly doubling from 58,000 in 2025 to 105,000 in 2026, a jump of 81% and more than double the 2017–2019 Q1 average of 52,000. Completions in the region climbed 42.1% year-over-year to 108,000 units, 80% above pre-pandemic levels, while the 144,000 units under construction were still 9.1% above the pre-2020 baseline despite a 7.1% pullback from last year. That pipeline is already visible in the rent data: Boston's median asking rent fell 2.9% year-over-year in April and Philadelphia's declined 1.5%, even as New York continued to buck the trend with a 1.1% annual increase.
The South remains the volume leader but is further along in its current cycle. The region had 279,000 units under construction in the first quarter, down 11.1% from 314,000 a year earlier but still nearly 23% above its pre-pandemic Q1 average of 227,000. Starts surged 40.2% year-over-year to 230,000 units, about 27.8% above their 2017–2019 benchmark, indicating that developers are pressing ahead despite a meaningful drop in recent deliveries. Completions in the South fell 26% from 269,000 to 199,000 units, though they remained 15.7% above pre-pandemic norms, a combination that could create a brief period of absorption before the next wave of product under construction reaches the market.
In the Midwest, the pipeline is smaller but still elevated relative to historical patterns. Units under construction slipped 5.4% year-over-year to 87,000, yet that total sits about 20.8% above the region's pre-pandemic Q1 average of 72,000. Starts fell 12.5% from 56,000 to 49,000, though they remain roughly 40% above pre-2020 norms, while completions edged down just 1.6% to 63,000 but stand more than 50% above their pre-pandemic baseline. Taken together, those numbers suggest a more measured expansion, with enough new supply to influence rents without fundamentally reshaping market balance in most Midwestern metros.
West Pulls Back As Rents Soften
The West presents the clearest break from the national story. The region had 174,000 multifamily units under construction in the first quarter, down 14.7% from 204,000 a year earlier and 4.4% below its pre-pandemic Q1 average of 182,000. Starts fell to 77,000, a 28% annual decline and about one-third below the 2017–2019 average of 114,000, while completions plunged 37.9% year-over-year to 100,000 units, now 8.3% under their pre-2020 baseline. That makes the West the only region where completions have dropped below pre-pandemic norms at a time when renters in markets such as Los Angeles, Denver and Phoenix are still seeing rent declines of 1.7%, 3.4% and 4.2%, respectively.
Forward-looking projections in the report indicate that regional differences in stock growth will persist. By the first quarter of 2027, rental housing stock growth is expected to be strongest in the Northeast at 1.1%, followed by the South at 0.9%, with the Midwest and West both at 0.7%. For capital allocators, that implies that the more aggressive construction in the Northeast and South could sustain renter leverage longer, while the West's retrenchment may set the stage for tighter conditions once today's modest rent relief is worked through.
At the metro level, developers and investors face a patchwork of outcomes. Sun Belt markets such as Austin, San Antonio, Nashville and Tampa are still registering annual rent declines of 5.3%, 4.7%, 4.8% and 4.3%, respectively, reflecting the heavy building cycle of recent years that is still working through lease-up and concessions. In contrast, Kansas City and Pittsburgh are among the few large metros with rent growth above 3%, suggesting that new supply there has been more constrained even as the broader Midwest pipeline remains elevated over its pre-pandemic base. On the coasts, San Jose's 1.3% annual rent gain stands out against declines in San Diego, San Francisco and Seattle – an illustration of how tech-centric markets with limited new construction can diverge from regional trends.
