How Old Is Claremont's Housing Stock?
With 67% 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
While newer cities carry lower aggregate plumbing risk from lead-era construction, Claremont sits firmly in the older category. The median build year of 1973 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing — and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
Over half of homes in Claremont were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Claremont: Remediation Cost in Perspective
Across the Claremont housing market, the estimated remediation share lands in a middle tier — not a minor footnote, but not a prohibitive burden either; the cost-to-value ratio reflects a moderate equity commitment, one that sits above routine maintenance territory and warrants a dedicated line in the household budget.
Remediation costs are moderate relative to home values in Claremont. The estimated $300–$1,600 range is manageable for most homeowners but still worth budgeting for. Home values are 64% below the Illinois average.
Protecting Children from Lead in Claremont
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.
Households with kids in the home — for whom CDC guidance places particular weight on minimizing exposure — face a specific local picture in Claremont. 67% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.
