How Old Is Vienna's Housing Stock?
With 72% 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. Vienna's median build year of 1975 places it squarely in that category.
Over half of homes in Vienna were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Vienna: Remediation Cost in Perspective
Because property values in Vienna comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Vienna are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 16% below the New Jersey average.
Protecting Children from Lead in Vienna
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.
Older stock in Vienna represents 72% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
