Jun 2, 2025 - Residential “Missing Middle” Construction Sees Gains

• So-called “missing middle” medium-density housing, which includes duplexes, townhouses, and other smaller multifamily properties, has gained in popularity over the last several quarters, according to the National Association of Home Builders. Multifamily properties in the missing middle (2 to 4 units) have generally been out of favor since the Great Recession, but they are experiencing a resurgence. In the first quarter of 2025, there were 5,000 construction starts for housing properties with 2 to 4 units, which was flat compared to a year earlier. However, over the past four quarters, the number of missing middle residential construction units reached 23,000, marking a 53% increase over the four quarters before that period. The missing middle segment’s gains may be limited absent zoning reform that allows for increased density.
• The total value of construction starts decreased by 9% in April compared to March, according to Dodge Construction Network. Nonbuilding construction starts dropped 22%, as utility starts fell 70% and highway and bridge starts were down 8%. Residential starts fell 4.2% month-over-month in April; single-family starts dropped 5%, while multifamily starts were down by 3%. Nonresidential building starts fell 3% in April, as a 2% rise in institutional starts and a 78% jump in manufacturing projects were not enough to offset a 21% decline in commercial starts. Dodge Construction Network chief economist Eric Gaus said, “Broad-based monthly declines in construction starts represent a troubling signal for the sector. While not definitive, the slowdown in April aligns with delays in the planning pipeline and other economic data that capture the volatility and uncertainty of all the April tariff announcements. Uncertainty around trade policy and the economy’s direction will continue to weigh on construction activity in the coming months.”

• The number of building permits issued for single-family, privately-owned housing units decreased 5.1% in April 2025 compared to March and fell 6.2% year-over-year. Single-family housing starts dropped by 1.6% month-over-month and were down 12% compared to April 2024. Single-family housing completions declined 5.9% in April from the previous month and decreased 12.3% year-over-year. Housing starts in April were pressured by tariff-related economic uncertainty, high mortgage rates, and rising costs for building materials, according to the National Association of Home Builders (NAHB).
• Utilities and grid operators are grappling with a flood of speculative interconnection requests for data centers that may never be built, according to Utility Dive. Grid optimization software firm Camus Energy estimates there are between five and 10 times as many interconnection requests as the number of data centers being built. US data center load growth forecasts often diverge widely. A 2024 projection by the RAND Corporation estimated the AI sector would boost power demand by 347 gigawatts (GW) by 2030. In April 2025, Schneider Electric cited other sources that estimate growth will be less than 100 GW. Speculative requests by data center developers make it challenging for grid operators and utilities to plan for future power needs. To reduce the risks of overbuilding, some utilities are introducing standardized large-load interconnection processes, and others are requiring data center developers to shoulder more of the upfront costs.
