If a building was constructed prior to what year must the lead paint disclosure form be given to prospective tenants and buyers?

The correct answer is 1978 because that year marks the implementation of regulations concerning lead-based paint in residential properties. The U.S. government banned the use of lead-based paint in residential properties in 1978 due to the health risks it poses, particularly to children. Consequently, any property built before this date must comply with the requirement to provide prospective tenants and buyers with a lead paint disclosure form. This disclosure informs them of the potential presence of lead-based paint and the associated risks, allowing them to make informed decisions regarding their health and safety. The focus on properties constructed prior to 1978 aligns with these regulations to ensure awareness and protection against lead exposure.
