663 N 35th StUnder construction

4-unit residential new construction, zoned RM1.

A 4-unit residential building is set to rise at 663 N 35th St in University City & Powelton, the kind of by-right infill quietly reshaping the block. It was cleared to build in Dec 28, 2021.

The 2,000 sq ft site is zoned RM1, which supports a building on the order of 4 stories by right. Records show the parcel last traded in 2022 for $750K. The plans call for new construction of a four story, four family dwelling with roof decks and roof deck access structures to include underpinning as per approved plans and bbs variance. building to be fully sprinklered per nfpa 13. *2018 ibc review* **separate permits required for mep & fire suppression work** .

The owner of record is 661 N 35th 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 351 units of new supply — including the 19-unit project at 723 N 35th St, the 90-unit project at 3314-20 Fairmount Ave, the 20-unit project at 3310 Fairmount 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?
