Philadelphia Specific Research

For several decades Philadelphia possessed more houses than households. As its population dove by 25% after 1950, homes were left to deteriorate and the City suffered as 60,000 properties were abandoned over the next five decades. Today, Philadelphia’s population is growing again and its property values are rising. From 2004 to 2014, single-family homes appreciated an average of 22% in the city.1 This makes preserving the city’s affordable rowhouses critical.

From Mantua to Kensington residents are asking for help repairing their homes in order to ensure that they can remain in their neighborhoods as new amenities and residents are coming in.

The city and its non-profits have repaired thousands of homes over the past decades to stop deterioration and abandonment. Below are key studies that analyze those efforts, their strengths and their weaknesses.
