Washington County: 63% of 27,949 housing units were built before 1980, about the same as the Ohio share of 63% (Census ACS 2020–2024, table B25034). EPA links lead-based paint to homes built before 1978, and asbestos was common in building materials of that era. The ACS groups years by decade, so 1980 is the nearest cut.

Older homes within 25 miles

About 53,050 homes built before 1980 are in the 5 counties whose centre lies within 25 miles of this lab (Morgan County, Noble County, Pleasants County, Washington County, Wood County).
