730 Chestnut StUnder construction

42-unit mixed-use new construction, zoned CMX5.

A 42-unit mixed-use building is set to rise at 730 Chestnut St in Old City & Society Hill, a mid-scale addition to one of the city's busier development corridors. It was cleared to build in Mar 16, 2021.

The 4,260 sq ft site is zoned CMX5, which supports a building on the order of 7 stories by right. Records show the parcel last traded in 2025 for $3.0M. The plans call for new construction of a seven (7) story structure to include forty two (42) dwelling units and a shell commercial space (use registration & fit-out permits required prior to occupancy) as per approved plans. building to utilize horizontal separations to create two (2) separate buildings with two (2) different construction types (basement through second floor - type ia and 3rd through 7th floors - type iiia). building to be fully sprinklered per nfpa 13 and include standpipes per nfpa 14. fire watch required per code bulletin f-2001. *2018 ibc review* **separate permits required for mep & fire suppression work**.

The owner of record is Four Tigers Limited. 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, 1 other major projects have broken ground since 2022 — roughly 51 units of new supply — including the 51-unit project at 217 N 9th 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?
