225 W Rittenhouse StUnder construction

37-unit residential new construction, zoned CMX2.

A 37-unit residential building is set to rise at 225 W Rittenhouse St in Germantown, the kind of by-right infill quietly reshaping the block. It was cleared to build in Dec 17, 2021.

The 10,823 sq ft site is zoned CMX2, which supports a building on the order of 5 stories by right. The parcel last changed hands in 2020. The plans call for new construction of a five (5) story structure to include vacant commercial space (use registration & fit-out permits required prior to occupancy), thirty-seven (37) dwelling units and accessory parking as per approved plans. fire retardant treated studs and sheathing required in exterior walls for type iii construction. building to be fully sprinklered per nfpa 13 and include standpipes per nfpa 14. fire watch required per code bulletin f-2001. *2018 ibc* **separate permits required for mep & fire suppression work** amendment approved 3/17/22 amend new construction permit cp-2020-006666 for change to dprc-si and to include underpinning and sheeting/shoring as per approved plans. amendment approved 3/13/23 amend new construction permit cp-2020-006666 to include rated fire and water meter rooms in the basement level as per approved plans. .

The owner of record is Kabb Holdings 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, 2 other major projects have broken ground since 2022 — roughly 65 units of new supply — including the 33-unit project at 26-34 Church Ln, the 32-unit project at 184 E Chelten 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?
