Housing Age Profile
A median build year of 1983 in Seldovia 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 Seldovia were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Seldovia Homeowners
What does remediation cost in financial context for Seldovia homeowners? Proportionally very little — the equity share here is low, and addressing documented issues is a manageable planning question rather than a material financial burden.
Remediation costs in Seldovia are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 1% below the Alaska average.
Lead Exposure Risk for Children in Seldovia
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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet — and where 47% of Seldovia homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.
