Housing Age Profile
Because the majority of Maddock's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1964 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Maddock were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Maddock Homeowners
How does remediation fit within the broader financial picture for Maddock homeowners? The equity share is moderate — large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.
Remediation costs are moderate relative to home values in Maddock. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 56% below the North Dakota average.
Lead Exposure Risk for Children in Maddock
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Routinely in Maddock, where 86% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
