Housing Age Profile
Hillman's housing stock is predominantly older, with a median build year of 1971 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here — a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.
Over half of homes in Hillman 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 Hillman Homeowners
Within the Hillman market, estimated remediation claims a small portion of typical property equity — the financial burden is proportionally low.
Remediation costs in Hillman are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 14% above the Minnesota average.
Lead Exposure Risk for Children in Hillman
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 58% of the Hillman inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.
