13-unit residential new construction, zoned RM1.
A 13-unit, three-story building has been delivered at 1515-19 W Dauphin Street in Strawberry Mansion, with accessory parking rounding out the program on a 5,193-square-foot lot. The project recently underwent layout revisions and a change in design engineer, per an April amendment, and includes full NFPA 13 sprinklers. The property has been held by Academy For Professional since 1997, long enough to ride out the neighborhood's roughest years before pulling the trigger on new construction.
The RM1 zoning here is a straight shot for moderate-density residential, and the developer used it as intended. Strawberry Mansion has seen scattered multifamily comeback plays in recent years, though they've been sporadic rather than block-shifting. This site sits within range of at least 36 units delivered or in the pipeline within a half-mile radius, including a 17-unit project at 2213-15 N Broad Street and a 19-unit building at 1108 W Dauphin Street—evidence that patient developers are willing to bet on the Broad Street corridor and pockets of Dauphin.
What's notable is the density: 13 units on roughly 5,200 square feet is tight, disciplined infill, and the accessory parking acknowledges the realities of tenant demand without sprawling. The project's completion adds modestly to the area's stabilized rental stock and suggests that parcels in similar RM1 zones along this stretch—particularly those assembled long ago—may finally pencil for smaller-scale builders who've been sitting on land through the lean decades.
