Housing & Infrastructure in Addison
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
Federal restrictions on lead pipe, solder and flux in new drinking water plumbing date from the 1986 Safe Drinking Water Act amendments; the median build year of 1995 for Addison is one reference point against that date.
Most homes in Addison were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Addison
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Homes built before 1986 are more likely to have lead pipes, fixtures or solder, and census figures put that share of Addison housing at about 28%. The lead figure used here, an average of ZIP-level 90th-percentile results, sits under 0.010 mg/L. Neither number shows what flows from a particular family's faucet; a test of that faucet is the only direct measure.

Historical NFIP Claim Context in Addison
Historical NFIP data for Addison contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $2,745. 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 $500 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.
