Housing & Infrastructure in Juneau
With 74% 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
Reading the housing age data for Juneau — median build year 1965 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Juneau 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 Juneau Homeowners
Cost-to-value data for Juneau produces a high remediation-share classification — the equity impact here is elevated, placing this market in the tier where financial preparation is a meaningful factor in how homeowners approach documented issues.
At 2.6% of home value, remediation costs in Juneau represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $3,260–$8,220. Home values here are 8% below the Wisconsin average.
Lead Exposure Risk for Children in Juneau
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.
74% — that captures the slice of Juneau housing built before the federal ban on solder containing lead. Aggregate utility samples have also moved past the action threshold, meaning the system-level data and the housing-inventory data point the same direction. Households with kids or pregnant residents face a practical question that only a faucet sample can answer for one specific address, with certified filter options through retailer networks available where confirmed results warrant it.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

- Check your home's plumbing. With 74% of homes built before 1986, lead solder is a real possibility.
