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
Banned from residential plumbing in 1986, lead solder was a near-universal feature of copper plumbing before that cutoff. In Addison, where the median build year is 1995, the majority of housing falls into the post-ban category — though the older fraction of the stock still carries the residual risk that comes with pre-1986 pipe and solder materials.
Most homes in Addison were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Addison Homeowners
In Addison, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Addison are relatively low compared to home values. The $1,250–$3,200 estimated range is a small fraction of median property value. Home values are 100% above the Texas 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.
28% — that captures the slice of Addison stock built before federal rules removed lead-bearing solder from new construction. Combined with system samples below the regulatory action mark, the picture points to a quiet baseline, with one-home draws as the only direct read on a specific address.

Flood & Climate Risk in Addison
Although Addison's flood history doesn't reach high-severity thresholds, NFIP data documents 5 claims and FEMA maps place 100% of ZIP codes in designated flood zones — a combined profile that makes flood-related water quality considerations a reasonable planning baseline.
Addison has a moderate flood history with 5 FEMA claims averaging $1,647 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$2,000</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.
