How Old Is New Lisbon's Housing Stock?
With 47% 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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In New Lisbon, the median build year of 1982 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in New Lisbon were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

New Lisbon: Remediation Cost in Perspective
Property equity in New Lisbon sits at a moderate ratio to estimated remediation costs — a classification that reframes the household financial perspective from routine maintenance to deliberate budgeting, where most homeowners have a realistic path to addressing documented water and safety issues if they map the financial commitment against available resources before committing to scope.
Remediation costs are moderate relative to home values in New Lisbon. The estimated $950–$3,200 range is manageable for most homeowners but still worth budgeting for. Home values are 28% below the Wisconsin average.
Protecting Children from Lead in New Lisbon
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.
When older housing represents 47% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual New Lisbon address.

Climate-Related Water Risk for New Lisbon

New Lisbon has a moderate flood history with 6 FEMA claims averaging $7,176 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>$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.
