Housing & Infrastructure in Lathrop
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 2006, much of Lathrop's housing falls on the safer side of that line - though homes built before 1986 still warrant testing regardless of the city-wide profile.
Most homes in Lathrop were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Lathrop Homeowners
Property equity in Lathrop 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 Lathrop are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 18% below the California average.
Lead Exposure Risk for Children in Lathrop
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.
Aggregate sampling rests beneath the federal action threshold here, while only 20% of Lathrop housing predates the solder rule change.

Historical NFIP Claim Context in Lathrop
Historical NFIP data for Lathrop contains 29 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $30,262. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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>$2,400</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.
