How Old Is Milroy's Housing Stock?
With 82% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Milroy — it's the dominant profile. The median build year of 1953 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Milroy were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Milroy: Remediation Cost in Perspective
In Milroy, 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 Milroy are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 32% below the Minnesota average.
Protecting Children from Lead in Milroy
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: 82% of Milroy 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.
