What might indicate a constructive eviction?

Constructive eviction occurs when a landlord's actions make the rental property uninhabitable, effectively forcing the tenant to leave, even if the landlord has not formally evicted the tenant. When a landlord fails to provide essential services—such as heat, water, or proper maintenance—these deficiencies can render the property unlivable, thus allowing the tenant to claim constructive eviction.

In this context, if the landlord does not fulfill their obligation to maintain the property and provide basic services, it creates an environment that is unsuitable for living. This breach of duty may legally justify the tenant's departure, as they can argue that the living conditions have become intolerable due to the landlord's negligence. The other scenarios presented, such as raising the rent, changing locks without notice, or giving notice to vacate, do not directly correspond to the legal grounds for constructive eviction, which specifically hinges upon the landlord's failure to provide necessary services.
