Civil Code §1951.2 — The Four Categories of Recoverable Damages
When a commercial landlord terminates a lease due to the tenant's breach, Civil Code §1951.2(a) authorizes recovery of four categories of damages, each with specific rules:
Category 1: Unpaid Rent Through Termination Date
The worth of the unpaid rent for the period through the date of termination. This is the straightforward back-rent component — all rent (including additional rent such as CAM, taxes, and insurance if defined as rent in the lease) that accrued and went unpaid from the date of default through the termination date.
Category 2: Future Rent — Worth at Time of Award
The "worth at the time of the award" of the amount by which the unpaid rent for the balance of the lease term exceeds the amount of such rental loss that the tenant proves could be reasonably avoided. In plain terms: the present value of all rent that would have been paid for the remainder of the lease, discounted to today's dollars, less any rent that could have been recovered through mitigation.
Category 3: Consequential Damages
Any amount necessary to compensate the landlord for all the detriment proximately caused by the tenant's breach — including costs of re-letting the space (broker commissions, marketing costs, tenant improvement allowances for a new tenant), carrying costs during the vacancy period, and legal fees (if the lease provides for fee-shifting).
Category 4: Lease-Specified Provisions
Any other amounts or remedies specifically provided in the lease, to the extent not otherwise prohibited by law. Commercial leases frequently contain liquidated damages clauses, specific damage formulas, or rent acceleration provisions.
What Landlords Cannot Recover
Under Civil Code §1951.2(b), any amount of rental loss after the date of termination that the tenant proves could have been reasonably avoided is not recoverable. This is the mitigation defense — the tenant bears the burden of proving the landlord failed to mitigate.
Civil Code §1951.4 — The Landlord's Duty to Mitigate
What is the Duty to Mitigate?
Under Civil Code §1951.4, a California commercial landlord who terminates a lease due to the tenant's breach must make reasonable efforts to re-let the property at a reasonable rent before seeking future rent damages from the tenant. This obligation exists regardless of what the lease says — it is a statutory duty that cannot be waived in the lease.
What Counts as Reasonable Mitigation?
Courts evaluate mitigation efforts based on what a reasonably prudent landlord would do in similar circumstances:
- Listing the property with a commercial real estate broker promptly after eviction
- Marketing at market rate (not at an inflated rate that deters prospective tenants)
- Responding to and pursuing legitimate inquiries from prospective tenants
- Making necessary cosmetic improvements or repairs to make the space leasable
- Accepting reasonable lease terms from qualified replacement tenants
What Does NOT Constitute Adequate Mitigation?
- Listing the property at significantly above-market rent
- Refusing to consider qualified tenants for pretextual reasons
- Leaving the property vacant with no active marketing efforts
- Demanding lease terms materially different from market standards
Who Bears the Burden of Proof on Mitigation?
Under Civil Code §1951.2(a), the tenant bears the burden of proving that the landlord failed to mitigate and that rental losses could have been reasonably avoided. The landlord does not have to prove it mitigated — the tenant must prove it didn't. However, landlords who fail to document mitigation efforts create easy targets for this defense.
