California Civil Code Section 1951.2: Damages and Mitigation

California Civil Code Section 1951.2 sets out what a landlord can recover in money damages after a lease terminates because of the tenant’s breach. The statute allows four categories of recovery: unpaid rent earned before termination, rent lost from the termination date through the court’s judgment, future rent for whatever remains of the lease term after judgment, and any other amount needed to compensate for harm the breach caused. Each rent-loss category is reduced by whatever the tenant proves the landlord could have reasonably avoided.

When Section 1951.2 Applies

Section 1951.2 kicks in once the lease has actually ended. That happens either when the tenant abandons the property or when the landlord lawfully terminates the tenant’s right to possession. Until one of those things occurs, the landlord is still operating under the lease and any unpaid rent is collected as ordinary rent, not as statutory damages.

The distinction matters because a landlord who wants to keep the lease alive rather than end it has a separate option under Civil Code Section 1951.4. That path is available only when the lease permits it, and it is discussed briefly below. Everything else in this article assumes the lease is over.

The Four Categories of Recoverable Damages

Unpaid Rent Earned Before Termination

The landlord can recover all rent that was due but unpaid through the date the lease terminated. This is the simplest category. If the tenant was three months behind when the lease ended, those three months are recoverable in full.¹

Lost Rent From Termination to Judgment

The landlord can also recover the rent that would have accrued between the date the lease terminated and the date the court enters judgment. That amount is reduced by whatever rental loss the tenant proves the landlord could have reasonably avoided. If the unit could have been re-rented two months after the tenant left and the landlord did nothing to find a new tenant, the tenant gets credit for those two months.¹

Future Rent for the Remaining Lease Term

If time remains on the lease after judgment, the landlord can recover the unpaid rent for that remaining period, again reduced by the rental loss the tenant proves could have been reasonably avoided. This category comes with a condition. The landlord can only collect it if the lease specifically includes a provision allowing recovery of future rent, or if the landlord actually re-rented the unit before trial and can prove the reletting was done reasonably and in good faith. Without one of those two footholds, future rent stays off the table.¹

Other Damages Caused by the Breach

Beyond lost rent, the landlord can recover any additional amount necessary to compensate for harm caused by the tenant’s failure to meet lease obligations. This is where costs like cleaning, repairing damage beyond normal wear and tear, re-advertising the unit, and the shortfall between the original rent and the lower rent charged to a replacement tenant fit. The landlord has to show these expenses were directly caused by the breach.¹

How the Amounts Are Calculated

Section 1951.2 does not stop at listing what the landlord can recover. It specifies how each amount is valued at the time of the court’s award, and the two rent-loss periods use different formulas.

For unpaid rent earned before termination and for lost rent through the trial date, the “worth at the time of award” is calculated using the interest rate the lease specifies. If the lease is silent, California’s legal rate applies. For future rent covering the balance of the lease after judgment, the statute uses a different method. That amount is discounted to present value using the Federal Reserve Bank of San Francisco’s discount rate at the time of the award, plus one percent.¹

The split matters in long-term leases. Past-due rent grows at the contract or legal interest rate; future rent shrinks to present value at a rate tied to the Federal Reserve figure. On a lease with several years still to run, the discount calculation can meaningfully reduce the landlord’s recovery.

Who Has to Prove Mitigation

Every rent-loss category in Section 1951.2 turns on what could have been reasonably avoided, and the burden of proof on that question sits with the tenant. The landlord does not have to come to court with a file of listings and applications and prove diligent effort. The tenant has to prove the landlord failed to make reasonable efforts, and to prove what portion of the loss those efforts would have prevented.¹

That said, the statute is built around the assumption that landlords will try. The damage award will shrink if the tenant can show the unit sat empty while comparable units in the area were rented promptly, or that the landlord refused reasonable applicants to hold out for a higher rent. Courts look at documented efforts: listings, showings, communications with prospective tenants, and whether the landlord accepted qualified applicants.

The statute also makes clear that trying to mitigate does not cost the landlord anything. Efforts to re-rent the property, acts of maintenance, and preservation of the premises do not waive the right to recover damages under Section 1951.2.¹

What Reasonable Mitigation Looks Like

“Reasonable” is a fact question, and it depends on the rental market at the time. A landlord in a tight market who takes a few weeks to find a replacement tenant is in a very different position than one in a market with high vacancy who does not list the property for three months. The relevant proof is usually what the landlord actually did: how quickly the unit was advertised, at what asking rent, how many showings occurred, and how the landlord evaluated applicants.

Setting the asking rent well above the original rent, or above market, is one of the more common ways a landlord’s mitigation efforts get attacked. So is refusing applicants who look qualified on paper. Neither is automatically fatal, but both invite the tenant to argue that the vacancy was self-inflicted.

The Alternative Path: Section 1951.4

Section 1951.2 is not the only option. Civil Code Section 1951.4 lets a landlord keep the lease in effect after a tenant breaches and abandons the property, and collect rent as it comes due instead of suing for a lump-sum damage award. This can make sense for commercial leases with above-market rent or long remaining terms.²

Section 1951.4 is only available if the lease allows it. The lease must either include a provision referencing Section 1951.4, or it must permit the tenant to sublet or assign, whether freely or with the landlord’s reasonable consent. A lease that completely prohibits subletting and assignment closes off this remedy and forces the landlord into Section 1951.2.²

When a landlord goes this route, acts of maintenance, efforts to re-rent, and even the appointment of a receiver do not count as terminating the tenant’s right to possession. The landlord can take those steps without accidentally converting the situation into a Section 1951.2 termination.²

Putting It Together

A landlord using Section 1951.2 is asking the court for a single money judgment covering everything the breach cost, valued at the moment of the award. Past-due rent runs to termination. Post-termination lost rent runs to the judgment. Future rent, if the lease or a completed reletting supports it, covers the remainder of the term at present value. And any other loss the breach caused, from cleaning costs to a lower replacement rent, fits under the fourth category. Each of the three rent-loss buckets is reduced by whatever the tenant proves reasonable efforts would have avoided.

The mechanics reward landlords who document what they did after the tenant left: when the unit was listed, at what price, who was shown through, and who was accepted or turned down. That record is not required to prove the case in chief, but it is the record that answers a tenant’s mitigation argument at trial.
