Homes built before 1940 face the widest range of legacy hazards: lead paint throughout, asbestos in insulation and floor tiles, galvanized steel pipes prone to rust and lead leaching, and original knob-and-tube wiring that predates modern electrical standards.
What to Inspect
Budget for comprehensive lead and asbestos testing before purchase. A full inspection by a licensed inspector familiar with pre-war construction is essential.
Note for Oklahoma: Homes built before 1978 require lead paint disclosure under federal law. Oklahoma may have additional state-level requirements for lead testing.
