Whether a residential landlord seeking rent from a tenant who wrongfully abandons the premises must make reasonable efforts to mitigate damages by re-letting the apartment.
Holding
Yes. A residential landlord has a duty to make reasonable efforts to mitigate damages, and Joyce v. Bauman is overruled to the extent it holds otherwise.
Reasoning
The prior no-mitigation rule rested on an old property-law conception of a lease as a transfer of an estate to the tenant. Under that view, the tenant retained exclusive possession during the term, so the landlord supposedly had no obligation to deal with an abandoned apartment. Earlier New Jersey decisions, including Joyce and Muller v. Beck, followed that approach.
The Court concluded that this property-based distinction no longer fit modern residential leasing. Detailed lease covenants and modern housing relationships give leases a strongly contractual character. New Jersey's own decisions recognizing a warranty of habitability, duties to repair, and related landlord obligations had already departed from the rigid historical notion that a lease is merely an estate in land.
Ordinary contract law requires an injured party to take reasonable steps to avoid avoidable losses. Basic fairness therefore forbids a landlord from leaving an apartment vacant, allowing rent to accumulate, and shifting the entire avoidable loss to a defaulting tenant. The Court found no persuasive justification for preserving a special rule that treated residential landlords differently from other parties seeking contract damages.
When the landlord has other vacant apartments, reasonable mitigation means treating the abandoned apartment as part of the landlord's ordinary vacant inventory and making reasonable efforts to re-let it. The Court did not require the landlord to give the abandoned unit priority over every other available unit, because apartments may have different features and appeal to different prospective renters.
The landlord bears the burden of proving reasonable diligence. Although the breaching party ordinarily bears the burden to show that damages could have been mitigated, the landlord is better positioned to establish what efforts were made to market and re-let the premises. The Court expressly reserved whether the same duty applies in commercial leases.
