Downtowns Reimagined: Empty Offices Fuel a New Wave of Housing and Data Hubs
Empty office towers that once defined central business districts are being repurposed at a pace that would have seemed unlikely just a few years ago. Developers are converting offices into apartments and data centers at record rates, driven by persistent vacancy, rising demand for urban housing, and the economics of digital infrastructure.
The scale of the shift
The pipeline of office-to-residential projects has grown sharply. Conversion pipelines that numbered in the tens of thousands in 2022 have roughly doubled or more in many trackers, with estimates in recent reporting showing 70,000 to 90,000 apartment units identified in active or proposed conversion projects nationwide. That growth is concentrated in major metros such as New York, Washington, D.C., Los Angeles and Chicago, where existing zoning and market demand make projects viable.
Who is buying and why
Two distinct developer strategies are emerging. One group is focused on housing conversions that aim to create 24/7 neighborhoods by turning hollowed office floors into studio and mid-size units, often with ground-floor retail and shared amenities. A second, growing cohort sees value in converting structurally robust office cores into urban data centers that host cloud, enterprise and edge computing gear. Cities with strong fiber networks and available power capacity are especially attractive to data center developers. Some buildings that could not be made profitable as apartments are now commanding offers from technology infrastructure buyers.
Cities rewrite the rules
Municipal policy is accelerating conversions. Several cities have introduced tax breaks, zoning changes and fee waivers to lower the cost barrier for developers. San Francisco, for example, has advanced legislation and incentives to make conversions easier, while New York and Washington, D.C. have rolled out programs to reduce tax and regulatory friction for adaptive reuse. Those moves are aimed at filling storefronts, raising downtown population counts, and stabilizing municipal tax bases. Local policy has become a critical determinant of whether a conversion moves from idea to construction.
Hard economics and practical hurdles
Conversions are not simple. Costs for seismic upgrades, plumbing rework, and code compliance often rival new construction. In some cities, studies show conversion can cost as much as tearing down and rebuilding, which helps explain why only a fraction of announced projects reach completion. Developers and city planners say realistic feasibility studies, targeted subsidies, and streamlined permitting are necessary to close the gap between potential and delivered housing.
What this means for downtowns
The result is a kind of developer gold rush where capital chases adaptable buildings. Expect more mixed outcomes: successful projects that stitch life back into urban centers, and failed schemes where the math does not work. Over the next two years, conversion activity is likely to remain a defining theme in commercial real estate as cities balance growth, climate goals and digital infrastructure needs. For downtowns, the transition from office towers to homes and data hubs may be the fastest route to revival.
