A 0-unit residential building is set to rise at 650 Fairmount Ave in Northern Liberties, the kind of by-right infill quietly reshaping the block. It was cleared to build in Aug 28, 2026.

The 733 sq ft site is zoned RM2, which supports a building on the order of 3 stories by right. The plans call for - approved plumbing work associated with an (addition or alteration) per attached ez permit standard for plumbing.

The owner of record is Fairmount Manor Realty Co. 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 129 units of new supply — including the 55-unit project at 828-40 N 2nd St, the 74-unit project at 502 Wood 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?
