Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Smithville — it's the dominant profile. The median build year of 1988 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Smithville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Smithville Homeowners
At current valuations, Smithville sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Smithville are relatively low compared to home values. The $150–$1,400 estimated range is a small fraction of median property value. Home values are 18% below the Tennessee average.
Lead Exposure Risk for Children in Smithville
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.
Older interior plumbing shapes the local picture: 54% of Smithville homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
