Properties constructed before which year may contain lead?

Properties constructed before 1978 may contain lead-based paint, as that is the year when the U.S. government banned the use of lead-based paint in residential properties and other public buildings. Lead was commonly used in paint because it added durability and improved drying time, but over time it became evident that lead exposure posed serious health risks, especially to children and pregnant women. Thus, homes built before this cutoff date are subject to lead remediation requirements and should be evaluated when renovations are done. Knowing this time frame is critical for real estate professionals, as they must inform clients about potential health hazards before buying or renovating older homes.
