Typical housing stock: Pre-1940 (row houses, twins, older construction) — Row houses, twins, older detached, newer condos

Philadelphia's housing stock is among the oldest in the U.S. Row houses built before 1940 dominate many neighborhoods, bringing century-old plumbing, heating, and electrical challenges. The four-season climate with summer humidity and winter freezes stresses every system.
