Housing Age Profile

When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Winchester's median build year of 1972 places it squarely in that category.

Homes Built Before 1986

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 Winchester represents 59% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.
