Homes built before 1978 may have what environmental hazard in their paint?

The course teaches that residences built prior to 1978 may contain lead-based paint, which poses health risks—particularly to children and pregnant individuals. Federal law requires the Lead-Based Paint Disclosure for most pre-1978 housing, plus delivery of the EPA pamphlet and opportunity for lead evaluation. Maryland materials reinforce these requirements and Maryland-specific lead rules for certain rentals.
