313 S. 16th Street is an oversized, RM1-zoned, multi-level property steps from Rittenhouse Square, Center City, and the Broad Street Line, offering a rare by-right opportunity to create up to three residential units in one of Philadelphia’s most walkable locations. Currently configured as a professional office under an existing variance, the building features expansive floor plates across multiple levels, multiple bathrooms, strong natural separation between floors, and a layout that lends itself well to a three-unit conversion. Additional highlights include a secure vestibule entry, ample storage, an upper-level roof deck area, active fire alarm certification, and a prior ADA accessibility study with conceptual architectural renderings illustrating a compliant front-entry ramp and exterior access improvements that show how the building façade could be thoughtfully adapted for accessibility. With historic character, flexible interior space, and unbeatable access to transit, dining, and amenities, this property presents a compelling value-add or redevelopment opportunity for investors seeking a prime multifamily asset in a true Walker’s Paradise.
