How Old Is Masonville's Housing Stock?

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. Masonville's median build year of 1978 places it squarely in that category.
Over half of homes in Masonville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Masonville: Remediation Cost in Perspective
Property equity in Masonville 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 Masonville. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 64% below the New York average.
Protecting Children from Lead in Masonville
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 Masonville represents 75% 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 Masonville
Measured across the NFIP's multi-decade tracking period, Masonville shows a moderate flood record — 2 claims 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.
Masonville has a moderate flood history with 2 FEMA claims averaging $1,243 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>$2,400</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.
