Homes around this lab
Harris County: 37% of 1,917,790 housing units were built before 1980, above the Texas share of 33% (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.
