Pittsburgh, PA zoning map & districts

Pittsburgh's current zoning code was adopted in 1998-99 as Title Nine of the Pittsburgh Code of Ordinances, administered by the Department of City Planning's Zoning Division. The code combines standard residential, commercial, and industrial base districts with a large number of specially planned (SP) districts written for individual redevelopment sites, plus institutional and neighborhood-commercial districts that reflect the city's dense, hillside topography and legacy industrial land.

Pittsburgh's zoning map and code are maintained by the Department of City Planning's Zoning Division, which handles zoning determination letters for specific parcels.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Pittsburgh

Downtown Pittsburgh is governed by its own Golden Triangle district, and large hospital and university campuses (notably in Oakland) fall under dedicated Educational/Medical Institution districts rather than standard commercial zoning. Given the city's steep terrain, hillside and slope-related development standards are a routine part of due diligence on infill sites.

The parcel layer lands in the order demand does. Illinois went first because that's where the deals were; the next state is decided by who tells us what they're trying to underwrite. Tell us where you're building and what you wanted to run — you'll hear from us when Pennsylvania opens, and sooner if we need a test parcel.
