Housing Age Profile
Roughly balanced between older and newer construction, Marietta shows a median build year of 1981 — a mid-range figure that places meaningful amounts of the residential inventory on both sides of the 1986 federal plumbing-solder ban.
Most homes in Marietta were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Marietta Homeowners
At current valuations, Marietta sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Marietta are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 62% below the Texas average.
Lead Exposure Risk for Children in Marietta
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 44% of Marietta stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
