- More than 4.7 million square feet of office inventory has been converted, is under construction, or has been identified for conversion across the Greater Philadelphia region since 2020.
- Center City accounts for more than 36% of all office conversion activity identified across the Greater Philadelphia region. Strong housing demand, transit accessibility, and a large inventory of aging office buildings have positioned the urban core as the region's most active office redevelopment market.
- Of the 44 office conversion projects identified, 15 entered the pipeline in 2025 or later. The recent surge in activity comes as more than 50 office loans carrying over $1 billion in outstanding debt are set to mature within the next two years, increasing pressure on owners to reevaluate aging assets as workplace demand continues to evolve.
- Market stabilization has continued to be a growing topic of discussion across the region. Office conversions have played a significant role in this trend, with the removal of obsolete inventory helping vacancy and availability edge lower from recent peaks.
