A 14-unit residential building is set to rise at 4146-48 Parkside Ave in University City & Powelton, the kind of by-right infill quietly reshaping the block. It was cleared to build in May 6, 2021.

The 5,460 sq ft site is zoned RM1, which supports a building on the order of 5 stories by right. Records show the parcel last traded in 2016 for $180K. The plans call for new construction of a five (5) story detached structure for use as twenty-eight (28) dwelling units as per approved plans. building required to be fully sprinklered per nfpa 13 and include standpipes per nfpa 14. fire retardant treated studs and sheathing required for type iii construction. fire watch required per code bulletin f-2001.*2018 ibc review* **separate permits required for mep & fire suppression work** amendment approved 12/16/22 amend new construction permit cp-2020-005326 to include 2 hour rated mechanical shaft as per approved plans. .

The owner of record is 4148 Parkside LP. 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, 10 other major projects have broken ground since 2022 — roughly 221 units of new supply — including the 8-unit project at 1221 N 42nd St, the 49-unit project at 4272 Parkside Ave, the 8-unit project at 1203 N 41st 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?
