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

Housing Age Profile
Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 1992, much of Middle Granville's housing falls on the safer side of that line — though homes built before 1986 still warrant testing regardless of the city-wide profile.
Most homes in Middle Granville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Middle Granville Homeowners
When estimated remediation is placed alongside median property values in Middle Granville, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Middle Granville are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 20% below the New York average.
Lead Exposure Risk for Children in Middle Granville
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, Middle Granville has stayed under the action mark. Paired with a 14% 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.
