For homes to be affected by lead-based paint regulations, they must have been built before which date?

The correct answer is January 1, 1978. This date is significant because it marks the implementation of federal regulations regarding lead-based paint in residential properties. The U.S. Congress passed the Residential Lead-Based Paint Hazard Reduction Act in 1992, which mandated that homes built before this date be assessed for lead-based paint hazards. Homes constructed before January 1, 1978 are considered high risk for containing lead-based paint, which can pose serious health risks, particularly to children and pregnant women.

Understanding this law is important for real estate professionals, as it affects disclosure requirements and the safety measures needed when dealing with properties built before this date. Properties built after January 1, 1978 are not subject to these regulations, making this distinction critical for compliance and buyer awareness.
