How Old Is Lisbon's Housing Stock?
With 49% 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 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 Lisbon were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lisbon: Remediation Cost in Perspective
Looking at how documented remediation costs fit within Lisbon property values, the equity share lands in the moderate tier — a finding that positions the household financial perspective between routine maintenance and a significant budget commitment, where most homeowners can successfully address documented issues by treating the expense as a planned financial priority rather than an unexpected one.
Remediation costs are moderate relative to home values in Lisbon. The estimated $2,150–$4,600 range is manageable for most homeowners but still worth budgeting for. Home values are 13% below the Maine average.
Protecting Children from Lead in 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.
Older stock in Lisbon represents 49% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Climate-Related Water Risk for Lisbon
Measured across the NFIP's multi-decade tracking period, Lisbon shows a moderate flood record — 1 claim and 100% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Lisbon has a moderate flood history with 1 FEMA claims. 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>$3,300</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.
