Housing & Infrastructure in Grafton
With 46% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
For a city with a median build year of 1981, Grafton carries a housing profile that straddles the 1986 federal ban on lead solder in plumbing. Neither predominantly new nor predominantly old, the stock presents a moderate aggregate risk environment - with individual risk varying sharply depending on when and where a specific home was built.
Most homes in Grafton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Grafton Homeowners
At current valuations, Grafton falls in the moderate remediation-share tier - a level where treating this as a budgeted line item rather than an ad-hoc expense is the practical approach.
Remediation costs are moderate relative to home values in Grafton. The estimated $1,900–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 21% above the Illinois average.
Lead Exposure Risk for Children in Grafton
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.
Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 46% of Grafton stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.

Historical NFIP Claim Context in Grafton
Historical NFIP data for Grafton contains 791 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,331. 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.
