How Old Is Swedesboro's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
With a median build year of 2009, Swedesboro's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 — the year lead solder in plumbing was federally banned — meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Swedesboro were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Swedesboro: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Swedesboro is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Swedesboro are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 27% below the New Jersey average.
Protecting Children from Lead in Swedesboro
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 Swedesboro represents 32% 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 Swedesboro
Measured across the NFIP's multi-decade tracking period, Swedesboro shows a moderate flood record — 16 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.
Swedesboro has a moderate flood history with 16 FEMA claims averaging $12,040 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>$2,200</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.

What You Can Do in Swedesboro
