Housing & Infrastructure in Addison
With 75% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The median home in Addison was built in 1978 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Addison were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Addison Homeowners
At current valuations, Addison sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Addison are relatively low compared to home values. The $950–$3,200 estimated range is a small fraction of median property value. Home values are 71% above the Illinois average.
Lead Exposure Risk for Children in Addison
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 75% of Addison stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.

Flood & Climate Risk in Addison
Addison carries a substantial flood exposure profile — 644 claims filed over the program's long tracking window and 100% of ZIP codes within FEMA flood zones. For water quality, that exposure level means flooding has likely stressed local treatment and distribution infrastructure on multiple occasions, creating periodic windows of elevated contamination risk.
Addison has a significant flood history with 644 FEMA flood insurance claims on record, averaging $13,886 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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. Flood damage can add significantly to the estimated <strong>$1,900</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
