Housing & Infrastructure in Geneva
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
A median build year of 2007 in Geneva is characteristic of a mixed-era city where plumbing risk depends heavily on the specific property. Homes built before 1986 may have lead-soldered copper joints; those from before 1970 face the added possibility of lead service lines. The percentages above capture how much of the residential stock falls into each risk era.
Most homes in Geneva were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Geneva Homeowners
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Geneva is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Geneva are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 6% below the Idaho average.
Lead Exposure Risk for Children in Geneva
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Geneva have approached or crossed the regulatory action level on multiple occasions. Combined with 34% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
