How Old Is Wilder's Housing Stock?
With 47% 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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1981 places Wilder in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Wilder were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wilder: Remediation Cost in Perspective
In Wilder, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Wilder are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 7% below the Idaho average.
Protecting Children from Lead in Wilder
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.
If 47% of the Wilder inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.
