4001 Ridge AveDelivered

27-unit residential new construction, zoned RSA5.

A 27-unit residential building is set to rise at 4001 Ridge Ave in East Falls, the kind of by-right infill quietly reshaping the block. It was cleared to build in Jan 11, 2019.

The 11,708 sq ft site is zoned RSA5, which supports a building on the order of 4 stories by right. The parcel last changed hands in 2019. The plans call for for the erection of a new, four (4) story attached structure with a roof deck accessed by pilot houses (to enclose access stairs only), with underground group s-2 occupancy (parking garage), vacant commercial spaces at ground floor front (separate use & newcon-fitout permits req'd prior to occupancy), and group r-2 (twenty-seven (27) dwelling units; all to be type b, minimum one (1) to be type a), from ground floor to 4th floor, as per plans; separate permits required for all mep/fsp work; building to be fully sprinklered throughout in accordance with nfpa 13, and with standpipes installed within exit stairways in accordance with nfpa 14; separate pa l&i permit required for elevator conveyance systems; no signs on this permit; see ap#879827 for zoning permit.

The owner of record is Pave Rox Development 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, 1 other major projects have broken ground since 2022 — roughly 10 units of new supply — including the 10-unit project at 3422 W Clearfield 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?
