Housing & Infrastructure in Troy
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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Troy, the median build year of 1996 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Troy were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Troy Homeowners
Given current Troy valuations, the remediation-to-property-value ratio is low - most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Troy are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 1% below the Virginia average.
Lead Exposure Risk for Children in Troy
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.
Older stock in Troy represents 34% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.
