Which provision related to a landlord's liability is considered unenforceable?

A provision that exempts a landlord from liability for damages resulting from the landlord's own acts is generally considered unenforceable because it contradicts public policy aimed at protecting tenants. In many jurisdictions, including Delaware, landlords have a duty to maintain safe and habitable premises. Allowing a landlord to entirely escape liability for their own negligent actions would undermine tenant protections and discourage responsible property management. Courts typically will not uphold such provisions because they pose an undue risk to tenants, who rely on the landlord to prevent and address dangerous conditions. Therefore, this type of provision is viewed as contrary to the principles of fairness and accountability in landlord-tenant relationships.

In contrast, the other types of provisions listed may have varying degrees of enforceability depending on the specific circumstances and other governing laws, but they do not intrinsically conflict with the foundational tenant protections established in property law.
