Housing Age Profile
A median build year of 1983 in Union Mills is characteristic of a mixed-era city where plumbing risk depends heavily on the specific property. Homes built before 1986 may have lead-soldered copper joints; those from before 1970 face the added possibility of lead service lines. The percentages above capture how much of the residential stock falls into each risk era.
Most homes in Union Mills were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Union Mills Homeowners
In Union Mills, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Union Mills are relatively low compared to home values. The $150–$1,400 estimated range is a small fraction of median property value. Home values are 8% below the North Carolina average.
Lead Exposure Risk for Children in Union Mills
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.
Older interior plumbing shapes the local picture: 49% of Union Mills homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
