Housing & Infrastructure in Little Chute
With 61% 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
The character of Little Chute's housing stock is one of deep historical layering — a median build year of 1971 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Little Chute 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 Little Chute Homeowners
Across the Little Chute housing market, the estimated remediation share sits at an elevated level — the cost-to-value ratio here is high enough that addressing documented water and safety issues becomes a material equity decision rather than routine maintenance, and most homeowners benefit from treating it as a structured financial planning exercise.
At 2.1% of home value, remediation costs in Little Chute represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,590–$6,280. Home values here are 12% below the Wisconsin average.
Lead Exposure Risk for Children in Little Chute
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 61% of housing comes from before the federal solder ban and citywide samples cross the regulatory action mark — as in Little Chute — household kits and a certified filter via retailer networks are the household-level tools.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
