Office-to-Residential Conversions Gain Traction Amid Vacancy Surges
By Majid Radaei, RadCRE · · Market Updates
With record office vacancies in major metros, office-to-residential conversions are accelerating. NYC alone projects 21,000 potential apartment units. We examine feasibility and recent deals.
The Shifting Landscape: From Cubicles to Condos
The post-pandemic commercial real estate market continues to recalibrate, with a persistent divergence between struggling office properties and robust demand for housing. This imbalance has driven a significant increase in interest and activity within the office-to-residential conversion sector. Once considered niche, these conversions are now seen as a viable solution to address high office vacancy rates in central business districts while simultaneously alleviating housing shortages.
Market Dynamics Fueling Conversions
Recent data underscores the urgency of this trend. According to Cushman & Wakefield, national office vacancy rates reached a record high of 19.8% in Q1 2026, with major markets like San Francisco and Houston experiencing even higher figures. Concurrently, the affordability crisis in housing persists, making new residential supply critically important. This confluence of factors has created a potent environment for adaptive reuse projects.
Cities are actively incentivizing these transformations. New York City, for instance, has projected that up to 21,000 apartment units could be created from office buildings constructed before 1990 under proposed zoning changes. Similar initiatives are underway in Chicago, where the LaSalle Street Reimagined program aims to revitalize the financial district through residential conversions, and in Los Angeles, which has streamlined its permitting process for such projects.
Recent Deals and Feasibility
While challenges such as structural limitations, zoning hurdles, and financing complexities remain, successful ventures are demonstrating the potential. For example, in Dallas, the former Comerica Bank Tower at 1717 Main Street is undergoing a significant conversion to luxury apartments by M2D Development, a project estimated to cost over $100 million. In Boston, Normandy Real Estate Partners (now part of Columbia Property Trust) converted the former John Hancock Life Insurance building at 200 Berkeley Street into a mixed-use project, including residential components. These projects highlight the substantial capital investment and intricate planning required but also the potential for significant returns.
The feasibility of these projects often hinges on several key factors:
- Building Geometry: Shallow floor plates and ample window lines are ideal for natural light in residential units. Deep floor plates can be challenging and costly to adapt.
- Location: Buildings in vibrant, walkable downtown areas with existing amenities are more attractive for residential tenants.
- Age and Condition: Older buildings (pre-1980s) often have more favorable structural elements and less complex systems than newer, more integrated office towers.
- Zoning and Incentives: Favorable local regulations and tax abatements significantly improve project economics.
RadCRE Perspective
Majid Radaei, Founder of RAD Commercial Realty, notes, "The office-to-residential conversion narrative is compelling, but the reality on the ground is far more nuanced than headlines suggest. While we see immense potential, especially in a supply-constrained housing market, not every office building is a viable candidate. The 'shallow floor plate' ideal is critical – converting a deep floor plate office tower often means creating internal units with no natural light, which severely limits market absorption and rental rates. Many older Class B and C downtown office buildings in secondary markets, particularly those built in the 60s and 70s, possess the right bones and are trading at prices that make the math work for a residential play, even with today's elevated construction costs. From a financing perspective, these deals require a sophisticated capital stack. Traditional lenders are often hesitant on the construction phase of a conversion due to perceived risk, pushing developers towards bridge-to-permanent financing, or seeking out mezzanine or preferred equity partners to fill the capital gap. We're actively structuring debt and equity for clients pursuing these opportunities, focusing on buildings with a clear path to high residential demand, strong access to amenities, and critically, a favorable per-unit conversion cost that still pencils out against new construction rents. Owners looking to dispose of their challenged office assets or developers seeking to acquire and convert must have a highly detailed budget that accounts for everything from HVAC overhauls to amenity space creation – ignoring these details is where projects go sideways."
Looking Ahead
As remote work trends persist and urban centers continue to prioritize live-work-play environments, office-to-residential conversions are poised to remain a strategic focal point for investors and developers. The ability to creatively repurpose underutilized assets into much-needed housing will not only reshape urban skylines but also provide significant investment opportunities for those who can navigate the complexities.
