When Clawson was built

The housing stock in Clawson peaked in the 1950s, when about 41% of today's homes were built. In total, 58% of Clawson 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.
