How Old Is Allouez's Housing Stock?
With 63% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Allouez, where the median build year is 1948, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Allouez were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Allouez: Remediation Cost in Perspective
In Allouez, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Allouez are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 43% below the Michigan average.
Protecting Children from Lead in Allouez
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.
Wherever 63% of local housing was built before solder rules changed — as is the case in Allouez — a faucet-level sample closes the gap that aggregate utility data cannot.
