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

Housing Age Profile

The year 1986 marks a critical threshold in residential plumbing safety: that's when the federal government banned lead solder from new construction, closing a major pathway for lead entering household drinking water via pipe joints. Yorkville's median build year of 2008 signals that most of the city's housing was built under the newer standard. The distribution above tells the full story — the post-1986 majority lowers aggregate risk, but the pre-1986 share still deserves scrutiny from anyone living in or purchasing an older home.

Most homes in Yorkville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Yorkville

25%
Homes Built Before 1986
0.0012
mg/L Avg Lead (Limit: 0.015)

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.

Through the multi-year window of EPA Lead and Copper Rule monitoring, Yorkville has stayed under the action mark. Paired with a 25% pre-rule housing share, the result places lead in a lower-priority spot on the local picture — without erasing the structural gap between citywide averages and what arrives at one specific tap.
