5-unit residential new construction, zoned CMX2.

A 5-unit residential building is set to rise at 5426 Market St in West Philadelphia, the kind of by-right infill quietly reshaping the block. It was cleared to build in May 5, 2025.

The 2,244 sq ft site is zoned CMX2, which supports a building on the order of 3 stories by right. The parcel last changed hands in 2024. The plans call for for the erection of an attached structure. structure for use as multi-family household living (5 dwelling units, including one (1) affordable dwelling unit) and vacant commercial use on the first floor (use registration & fit-out permits required prior to occupancy). sprinklered through per nfpa 13. separate permits required for plumbing, mechanical, electrical and fire suppression. a covered walkway or sidewalk closure shall be required in accordance with section 3306 of the ibc. separate building and/or streets department permits are required. **underpinning to be monitored by a pa licensed pe at all times** *amend 7-29-26; revise floor plan at first-floor commercial space per amended construction documents*.

The owner of record is 5426-28 Market Str Development Group LLC. The project's plan drawings are on file — worth a look for anyone underwriting the surrounding block.

For now it stands out on its block — there's little other major development within a half-mile, which makes the surrounding under-built parcels worth a closer look as this density arrives.

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?
