Housing & Infrastructure in Farmington
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
Farmington's housing stock skews relatively recent, with a median build year of 1993. 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 Farmington were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Farmington Homeowners
Property equity in Farmington 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 Farmington are relatively low compared to home values. The $1,900–$4,100 estimated range is a small fraction of median property value. Home values are 46% above the Minnesota average.
Lead Exposure Risk for Children in Farmington
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.
Even with citywide samples reading clean and just 28% of Farmington homes dating to the pre-rule era, individual-faucet conditions remain a separate question that aggregate utility data cannot resolve for one specific address. That gap is structural, not a function of severity.

Historical NFIP Claim Context in Farmington
Historical NFIP data for Farmington contains 14 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,762. Among ZIP codes with claim records, 100% 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>$2,900</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.

What You Can Do in Farmington
- Test your water at home. City-level data shows averages - your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
