Housing Age Profile
Medina's housing stock skews relatively recent, with a median build year of 2008. 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 Medina were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Medina
Property equity in Medina runs well ahead of estimated remediation costs — a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Medina are relatively low compared to home values. The $400–$800 estimated range is a small fraction of median property value. Home values are 18% above the Tennessee average.
Medina: Lead Risk & Vulnerable Populations
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.
Where pre-rule stock represents a smaller fraction of the inventory — 28% across Medina — the structural drivers of household exposure run thinner. Aggregate readings under the federal benchmark reinforce that picture, with one-home draws remaining the only direct measurement for a specific address.
