How Old Is Greenwich's Housing Stock?
With 45% 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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Greenwich, the median build year of 1997 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
A significant portion of Greenwich's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Greenwich: Remediation Cost in Perspective
At current valuations, Greenwich sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Greenwich are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 43% below the Utah average.
Protecting Children from Lead in Greenwich
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 45% 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 Greenwich address.
