How Old Is Hilliards's Housing Stock?
With 68% 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.

Housing Age Profile
Because the majority of Hilliards's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1976 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Hilliards were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Hilliards: Remediation Cost in Perspective
In Hilliards, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.

Protecting Children from Lead in Hilliards
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.
When older housing represents 68% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Hilliards address.
