How Old Is Sublette's Housing Stock?
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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Sublette's median build year of 1967 places it squarely in that category.
Over half of homes in Sublette were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Sublette: Remediation Cost in Perspective
The household financial picture for Sublette homeowners is proportionally favorable — addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.
Remediation costs in Sublette are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 1% above the Illinois average.
Protecting Children from Lead in Sublette
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 74% pre-rule share in Sublette keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
