Just two blocks from Rittenhouse Square and steps to the PATCO station at 16th & Locust, 315 S 17th Street offers an extraordinary opportunity to create a fully customized residence in one of Philadelphia’s most prestigious neighborhoods or to convert a grand historic building into multiple high-demand apartments or condos. This stately, Historic Register property features a quintessential Rittenhouse façade, two-car parking, an accessible rear ramp, a fire escape, and an up-to-date fire alarm system, with a recently expired sprinkler certification. Inside, the layout already includes half baths and kitchenettes on all four levels, plus five existing heating and cooling zones, offering tremendous flexibility for a luxury single home, multi-unit configuration, or hybrid owner-occupant scenario. Formerly approved for commercial use, the property invites creative redevelopment—live in a large three-bedroom, two-bath unit while renting additional units to offset your mortgage, or convert the entire building into premium rentals or condos with the added revenue potential of separately rented parking. All of this comes with unmatched convenience: a 10-minute walk to Suburban Station, an 8-minute drive to 30th Street, and just 22 minutes to the airport, placing the best of Center City living and commuter access right at your doorstep.
