Office-to-Residential Conversions: Unlocking Value Amidst Office Distress
By Majid Radaei, RadCRE · · Industry Insights
With record office vacancies, developers are increasingly eyeing conversions. NYC alone could see 13,000 units from conversions by 2033, addressing housing shortages and office obsolescence.
The commercial real estate landscape continues to grapple with shifting dynamics, particularly within the office sector. Elevated vacancy rates, exacerbated by sustained remote and hybrid work trends, have rendered numerous Class B and C office properties economically unfeasible in their current form. This challenge, however, presents a significant opportunity for adaptive reuse, with office-to-residential conversions emerging as a prominent strategy to unlock value and address persistent housing shortages in urban cores.
The Drivers Behind the Conversion Trend
According to data from CBRE, office vacancy rates in major U.S. markets reached approximately 18% in Q4 2025, a multi-decade high. Concurrently, the demand for affordable and workforce housing remains robust, particularly in gateway cities. This divergence creates a compelling arbitrage opportunity for developers capable of navigating the complexities of conversion projects. Cities like New York, Chicago, and Los Angeles are actively exploring incentives to encourage these transformations, recognizing their multi-faceted benefits.
New York City, for instance, has been a focal point for such initiatives. Recent legislative changes, including the "Housing Our Neighbors with Dignity Act" amendments and proposed zoning reforms, aim to streamline the conversion process and broaden the eligibility criteria for buildings constructed through 1990. CoStar data indicates that New York City alone could see the creation of over 13,000 new residential units from office conversions by 2033 if current momentum continues.
Key Considerations and Feasibility Challenges
While the economic drivers are clear, the feasibility of office-to-residential conversions is highly site-specific. Several factors dictate success:
- Building Geometry: Optimal candidates are typically shallow-plate buildings with ample natural light penetration, making it easier to create livable residential units with exterior windows. Deep-plate office towers often require significant structural modifications to introduce light wells or courtyards, substantially increasing costs.
- Mechanical, Electrical, and Plumbing (MEP) Systems: Converting large floor plates designed for commercial use to numerous smaller residential units often necessitates extensive re-piping and re-wiring, which can be a primary cost driver.
- Location and Amenities: Buildings in desirable urban locations with access to transportation, retail, and green spaces are more attractive for residential conversion, commanding higher rents or sale prices upon completion.
- Construction Costs: Hard costs for office conversions can range from $250 to $450 per square foot, depending on the scope and existing building conditions. These projects often entail bespoke design and engineering challenges, making accurate budgeting critical.
Notable Projects and Market Activity
Recent activity underscores the growing interest. In Chicago, developers such as The Sterling Bay Companies have been active, with projects like the 303 East Wacker Drive conversion reportedly exploring options to convert portions of the office tower into residential use. In Dallas, Goldman Sachs Asset Management and Crow Holdings Development converted the former Santander Tower, now called 'The National Residences,' into a mixed-use project featuring luxury apartments, demonstrating the potential for Class A office conversions.
Majid Radaei, Founder of RAD Commercial Realty, notes, "The economics for office-to-residential conversions are compelling, but they're not a panacea. Many buildings simply aren't suitable without prohibitive capital expenditure. Our focus at RadCRE, using RadCRE.ai, is to meticulously underwrite these opportunities for clients, identifying properties where the 'conversion premium'—the delta between the conversion cost and the 'as-is' office value plus the 'after-conversion' residential value—is truly accretive. We're seeing viable projects with IRRs in the mid-teens, often requiring creative capital stacks that blend traditional debt with preferred equity or subordinate debt at SOFR + 500-700 bps, depending on the asset's in-place cash flow and sponsor strength."
