Housing & Infrastructure in Willis
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
Over the decades, Willis accumulated housing from multiple construction periods. The median build year of 1994 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited - leaving a sizable share of homes on each side of that safety line.
Most homes in Willis were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Willis Homeowners
How much of a Willis home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.
Remediation costs in Willis are relatively low compared to home values. The $1,150–$2,750 estimated range is a small fraction of median property value. Home values are 27% above the Texas average.
Lead Exposure Risk for Children in Willis
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.
Pre-rule stock in Willis accounts for 30% of the inventory - a modest fraction - and citywide samples land safely beneath the federal action mark.

Historical NFIP Claim Context in Willis
Historical NFIP data for Willis contains 211 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $54,047. 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>$1,800</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.
