A 181-unit residential building is set to rise at 1306 Callowhill St in Northern Liberties, one of the larger new-construction projects underway in Philadelphia this cycle. It was cleared to build in Feb 2, 2021.

The 145 sq ft site is zoned CMX4, which supports a building on the order of 7 stories by right. The parcel last changed hands in 2020. The plans call for new construction of a seven (7) story structure to include vacant commercial space (use registration & fit-out permits required prior to occupancy), one hundred eighty-one (181) dwelling units and accessory parking garage as per approved plans. building to utilize horizontal separations to create two (2) separate buildings with two (2) different construction types (1st & 2nd floors - type ia and 3rd through 7th floors - type iiia). fire retardant treated studs and sheathing required for type iii construction. amended permit required prior to initial inspection to determine required protection for adjacent structure. **building to be fully sprinklered per nfpa 13 and include standpipes per nfpa 14. *2018 ibc review* amendment approved 5/13/21 amend new construction permit cp-2020-005477 to include sheeting & shoring and underpinning work as per approved plans and calculations. **separate permits required for mep & fire suppression work** amendment approved 6/18/24 amend new construction permit cp-2020-005477 to change dprc-si as per revised special inspections documentation.

The owner of record is Llcp Callowhill LLC. The project's plan drawings are on file — worth a look for anyone underwriting the surrounding block.

It isn't rising in isolation. Within a half-mile, 7 other major projects have broken ground since 2022 — roughly 349 units of new supply — including the 31-unit project at 326 N 12th St, the 81-unit project at 225 N 13th St, the 23-unit project at 1314-32 Spring Garden St. That kind of concentration is exactly what pulls land values, and buyer attention, toward a block.

We'll update this page as the project progresses — leasing, retail tenants, renderings, and construction milestones as they surface. The relevant question for investors and agents: what are the surrounding parcels worth to a builder now that this is coming?
