A 15-Foot-Wide Corner Lot in North Philadelphia Just Got a Commercial Storefront

840 square feet of new construction, two apartments, and ground-floor retail space on a lot most brokers would skip. That's the infill wave hitting North Philly's corners.

Permits were issued this week for a three-story mixed-use building at 609 West York Street in Hartranft, North Philadelphia, Philadelphia YIMBY reported. The footprint is 840 square feet of new construction on a corner lot just over 1,000 square feet. Fifteen feet wide, 56 feet long.

Ground floor is vacant commercial space with real storefront glazing facing York Street. Above it, two residential units with their own rear entrance, plus a cellar and a 400 square foot roof deck. Ping Architects designed it, SD General Contractor is building it, on a $200,000 budget.

Nobody builds new construction on a lot this small unless the zoning requires it or the numbers only pencil with commercial rent helping carry the residential units. CMX-2 zoning put commercial space on the ground floor by right, and that's the pattern worth watching across North Philadelphia's smaller corners right now: tiny lots, ground-floor glazing, a landlord who'll want a tenant in fast to help debt service. That's a below-the-radar lead for a small-format retail or service tenant looking for cheap rent on a real corner.

Why it matters

A 15-foot-wide corner just added ground-floor commercial space almost nobody is watching for. Small-format tenants who move first get the pick of North Philadelphia's infill corners.
