53-unit residential new construction, zoned RSA2.

A 40-unit residential building is cleared to build at 1510 W Allegheny Avenue in Strawberry Mansion, bringing four stories and partial basement to a 32,000-square-foot lot controlled by 1510 West Allegheny Ave LLC. The company acquired the parcel in 2021 and is now moving forward with a project that will include full sprinkler coverage and standpipes, with separate mechanical, electrical, plumbing, and fire-suppression work to follow. The RSA2 zoning allows the density by right, and the developer is taking full advantage of the buildable envelope on a site that's more than large enough to accommodate the scale.
The project adds to a modest but steady wave of multifamily development in this stretch of North Philadelphia. Within a half-mile, roughly 98 units are either planned or recently delivered, including a 43-unit building at 3249 N 16th Street, a 27-unit project at 3216 N 16th, and a 28-unit building at 3120 N Park Avenue. That cluster suggests patient capital is finding workable numbers in Strawberry Mansion, particularly on larger assemblages where unit counts can justify the construction expense.
1510 West Allegheny Ave LLC hasn't surfaced publicly as a repeat player, but the willingness to chase 40 units on a single parcel is a signal that the neighborhood's fundamentals—proximity to Fairmount Park, bus routes, and improving retail corridors—are attracting more than just scattered infill. The timeline from acquisition to construction readiness took roughly five years, a pace that's typical for teams navigating zoning, financing, and design approvals without headline-grabbing fanfare.
The quarter-acre footprint is unusual for the immediate area, where most residential lots are narrow rowhouse parcels. If 1510 West Allegheny performs, expect developers to scan the neighborhood for similar opportunities: oversized corner sites, former industrial parcels, or consolidated tax-delinquent strips that can support 30-plus units without requiring zoning variances. The math on smaller sites is harder to crack; this one shows there's still room to build at scale when the land costs and entitlement risk line up.
