Housing & Infrastructure in Addison
With 74% 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
The median home in Addison was built in 1967 — 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 $0–$800 estimated range is a small fraction of median property value. Home values are 4% below the Pennsylvania 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 74% 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.

- Check your home's plumbing. With 74% of homes built before 1986, lead solder is a real possibility.
