1309-25 Cambridge StDelivered

46-unit residential new construction, zoned CMX4.

A 46-unit residential building is set to rise at 1309-25 Cambridge St in Northern Liberties, a mid-scale addition to one of the city's busier development corridors. It was cleared to build in Jan 12, 2021.

The 10,412 sq ft site is zoned CMX4, which supports a building on the order of 6 stories by right. Records show the parcel last traded in 2020 for $1.4M. The plans call for amendment (2/23/2023) to revise exterior wall assembly and exterior wall type as per revised plans. for erection of a six (6) story attached structure for multi-family dwelling. for type ia construction on the ground floor and iiib construction above with a three (3) hour fire rated horizontal assembly above the ground floor creating two (2) buildings. 46 dwelling units & 15 accessory parking spaces flat roof w/ roof decks on top of 5th floor as per plans. a written, graphic and pictorial depiction of each individual truss with all relevant information about the design shall be provided to the building department for approval prior to installation.

The owner of record is Cambridge 9 Ozb 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, 12 other major projects have broken ground since 2022 — roughly 387 units of new supply — including the 70-unit project at 915-23 N Broad St, the 49-unit project at 918 N Broad St, the 13-unit project at 1435 W Girard Ave. 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?
