Cal. Civ. Code § 1951.2 provides the general remedies available to landlords upon a breach of lease by the tenant. Section 1951.2 states: (a) Except as otherwise provided in Section 1951.4, if a lessee of real property breaches the lease and abandons the property before the end of the term or if his right to possession is terminated by the lessor because of a breach of the lease, the lease terminates. Upon such termination, the lessor may recover from the lessee: (1) The worth at the time of award of the unpaid rent which had been earned at the time of termination; (2) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that the lessee proves could have been reasonably avoided; (3) Subject to subdivision (c), the worth at the time of award of the amount by which the unpaid rent for the balance of the term after the time of award exceeds the amount of such rental loss that the lessee proves could be reasonably avoided; and (4) Any other amount necessary to compensate the lessor for all the detriment proximately caused by the lessee’s failure to perform his obligations under the lease or which in the ordinary course of things would be likely to result therefrom.
Thus, landlords are under a duty to mitigate (i.e., try to re-rent the premises) but may seek the available remedies upon a breach of lease.
