Housing & Infrastructure in Raleigh
With 67% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Raleigh's median build year of 1972 places it squarely in that category.
Over half of homes in Raleigh 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 Raleigh Homeowners
At current valuations, Raleigh sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Raleigh are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 39% below the Illinois average.
Lead Exposure Risk for Children in Raleigh
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 67% pre-rule share in Raleigh keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
