Housing & Infrastructure in Willisburg
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Some cities skew heavily toward one construction era; Willisburg does not. The median build year of 1996 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk — with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.
Most homes in Willisburg were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Viewed from a financial planning lens, Willisburg sits in the high remediation-share tier — the equity impact of addressing documented issues is material, and deliberate preparation is more than a convenience here.

Lead Exposure Risk for Children in Willisburg
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 38% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Willisburg.

Flood & Climate Risk in Willisburg
