Housing Age Profile
With a median build year of 1999, Franklin's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 - the year lead solder in plumbing was federally banned - meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Franklin were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Franklin: 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.
When older housing represents 44% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Franklin address.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The <strong>$1,600</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
