Office-to-Residential Conversions Gain Traction Amidst Market Shifts
By Majid Radaei, RadCRE · · Market Updates
Despite headwinds, office-to-residential conversions are accelerating, with over 72,000 apartments created since 2020. Cities like Washington D.C. are leading this transformative trend.
The Growing Impetus for Office-to-Residential Conversions
The office sector continues to grapple with elevated vacancy rates and shifting tenant demands, a trend exacerbated by persistent hybrid work models. Concurrently, a severe housing shortage in many urban centers has fueled a compelling narrative for repurposing underutilized office buildings into residential units. This confluence of factors has pushed office-to-residential conversions to the forefront of commercial real estate development strategies.
According to a recent report by RentCafe and Yardi Matrix, over 72,000 apartments have been created through office-to-residential conversions across the U.S. since 2020. The pace of these conversions shows no signs of slowing, with 55,300 additional units currently in the pipeline. Washington D.C. has emerged as a leader in this trend, with its downtown business district experiencing significant conversion activity. For instance, in early 2024, JBG SMITH announced plans to convert 1900 L Street NW, an 185,000-square-foot office building, into residential units, reflecting a broader strategy to densify urban cores with housing.
Challenges and Opportunities in a Complex Market
While the concept is appealing, executing office-to-residential conversions presents numerous challenges. These include complex zoning approvals, the high cost of renovation—often exceeding $150-$200 per square foot—and the practical difficulties of transforming deep office floorplates into viable residential layouts that allow for natural light and efficient unit configurations. Structural considerations, HVAC systems, and plumbing infrastructure often require substantial capital expenditure, making financial feasibility a critical hurdle.
However, the opportunities for value creation remain significant. Data from Green Street Advisors indicates that residential properties generally command higher cap rates and offer more stable cash flows compared to distressed office assets in many markets. This differential in valuation can make conversions attractive, particularly in supply-constrained urban areas where housing demand outstrips supply, such as New York, Los Angeles, and Chicago. Developers like Silverstein Properties have demonstrated success in this arena, with projects like the conversion of 55 Broad Street in Lower Manhattan into 571 rental units, a project estimated to cost over $300 million and set to deliver new housing supply to a high-demand market.
Financing Landscape and RadCRE's Role
The financing landscape for these conversions is evolving. While traditional construction loans are available, the higher risk profile of adaptive reuse projects often necessitates more creative capital stacks. Bridge lenders and private equity funds are increasingly providing financing, often at higher interest rates. For instance, bridge loans for such projects might currently range from SOFR + 300-600 bps, depending on sponsor strength and project specifics. Developers may also seek mezzanine financing or preferred equity for equity gap funding, which can carry rates of 12-18%.
“The capital markets for office-to-residential conversions are maturing, but still require a nuanced approach," notes Majid Radaei, Founder of RAD Commercial Realty. "We're seeing significant interest from institutional lenders and private capital keen on supporting well-conceived projects in prime locations. However, the key is demonstrating a clear path to profitability by meticulously underwriting the construction costs, lease-up projections, and comparing the post-conversion value against the distressed office acquisition cost. Our clients benefit from our ability to navigate these complex capital stacks, whether it involves securing a senior construction loan, identifying mezzanine providers, or structuring joint venture equity to bridge funding gaps and optimize returns.”
