Renault Infrastructure Age
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
Why does housing age matter for water safety? Homes built before 1986 may have lead-soldered copper plumbing joints — a practice banned that year. Renault's median build year of 2018 places much of the city's housing in the post-ban era, reducing that specific risk pathway for most residents.
Most homes in Renault were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Renault
Remediation costs in Renault are small relative to typical property values — the cost-to-value ratio here is favorable.
Remediation costs in Renault are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 48% above the Illinois average.
Renault: Lead Risk & Vulnerable Populations
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.
Where pre-rule stock represents a smaller fraction of the inventory — 23% across Renault — the structural drivers of household exposure run thinner. Aggregate readings under the federal benchmark reinforce that picture, with one-home draws remaining the only direct measurement for a specific address.
