What year marks the cutoff for houses that need to be tested for lead?

The year that marks the cutoff for houses that need to be tested for lead is 1978. This is significant because the U.S. government banned the use of lead-based paint in residential properties in that year due to the health risks associated with lead exposure, especially in children. Homes built before this cutoff are likely to contain lead-based paint and therefore require testing to assess safety for residents. Understanding this benchmark is crucial for those assessing properties for potential lead hazards and ensuring proper safety measures are taken in older homes.
