Philadelphia’s rowhome-dominated housing stock is among the oldest in the US. Knob-and-tube wiring, lead paint, and lead water service lines are widespread. The city has one of the highest rates of lead service lines nationally. Combined sewer overflows affect many neighborhoods during heavy rain. Tax abatement expirations can cause sudden property tax increases on recently renovated properties. Gut-rehab flips vary widely in permit compliance. L&I violation history is common. Neighborhoods like Fishtown, Kensington, and Point Breeze are undergoing rapid transformation with dense permit activity.
