How Old Is Kuna's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Kuna's housing stock skews relatively recent, with a median build year of 2006. Homes constructed after 1986 avoid the lead-soldered copper joints that were standard before the federal ban — reducing aggregate risk from plumbing as a contamination pathway.
Most homes in Kuna were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Kuna: Remediation Cost in Perspective
When estimated remediation is placed alongside median property values in Kuna, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Kuna are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 25% above the Idaho average.
Protecting Children from Lead in Kuna
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.
Generally, the structural picture for Kuna runs in a quiet direction. Aggregate sampling rests under the federal action benchmark, and 17% of housing comes from the pre-rule era — a contained local footprint. That dual signal keeps lead in the background of local concerns, while a one-faucet measurement still answers a different question than any system average can: what is actually flowing from one specific tap on a given morning.
