What must a landlord do if a property has flooded regularly before leasing?

When a landlord is aware that a property has a history of flooding, they have a responsibility to ensure that prospective tenants are adequately informed about these past incidents. This duty falls under the principle of disclosure in property law, which aims to protect tenants from potential harm or unexpected issues that could affect their living conditions.

By notifying prospective tenants about previous flooding incidents, the landlord fulfills their obligation to provide critical information that could influence a tenant’s decision to rent the property. Transparency in these matters helps establish trust and allows tenants to make informed choices about the potential risks associated with the property.

While other options might seem reasonable, they either do not align with standard landlord obligations or do not directly address the necessity of informing tenants about past flooding. For instance, declaring the property unfit for leasing could be an extreme measure not required unless the property poses immediate health and safety risks. Similarly, offering insurance options or rent reductions doesn't ensure that tenants are fully aware of the property's history of flooding, which is the primary concern. Thus, the correct answer maintains the focus on the importance of informing tenants as part of a landlord's ethical and legal obligations.
