Los Angeles County: 70% of 3,650,466 housing units were built before 1980, above the California share of 56% (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.
