Lead-based paint disclosure is required for properties built before which year?

• A. Properties built after 1980
• B. Properties built before 1978
• C. All properties regardless of age
• D. Properties built between 1980 and 1990

Answer: (B)

Lead-based paint disclosure hinges on when lead paint was banned. In 1978 the federal government banned lead-based paint in residential housing, so properties built before that year may contain lead hazards and must disclose what is known about lead paint to buyers or tenants. The requirement covers those older homes, and after 1978 the federal rule doesn’t apply (though local laws can vary). That’s why the correct answer points to properties built before 1978, whereas the other options refer to years after 1978 or to all properties, which aren’t covered by this federal disclosure rule.
