When Shelby Township was built
The housing stock in Shelby Township peaked in the 1990s, when about 24% of today's homes were built. In total, 11% of Shelby Township homes predate 1960. That matters because basements built before the 1960s typically lack the sump pumps, perimeter drain tile, and backwater valves that became standard later, leaving many on their original, aging clay drain tiles.
