When Center Line was built

The housing stock in Center Line peaked in the 1950s, when about 26% of today's homes were built. In total, 53% of Center Line 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.
