How Old Is Deerfield's Housing Stock?
With 67% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of Deerfield's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1975 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Deerfield were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Deerfield: Remediation Cost in Perspective
The household financial picture for Deerfield homeowners is proportionally favorable - addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.
Remediation costs in Deerfield are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 228% above the Illinois average.
Protecting Children from Lead in Deerfield
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.
Routinely in Deerfield, where 67% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
