Landlords of multi-unit buildings built prior to 1978 must give prospective tenants ______.

Landlords of multi-unit buildings built prior to 1978 are required to provide prospective tenants with reports concerning lead paint in common areas due to the potential health risks associated with lead exposure. The federal Residential Lead-Based Paint Hazard Reduction Act mandates that landlords disclose any known information concerning lead-based paint and lead-based paint hazards in residential properties built before 1978. This is particularly critical because lead exposure can lead to serious health issues, especially for young children and pregnant women. Providing this information helps to ensure that tenants are informed about any possible risks and can make educated decisions regarding their housing.

Options that involve a history of repairs, pest control information, or a copy of the lease agreement do not specifically address the critical public health concerns related to lead-based paint that the law aims to mitigate. Only the requirement to disclose lead paint information aligns with federal regulations and is thus the correct choice in this context.
