California Civil Code Section 1951.4 gives a landlord whose tenant has broken the lease and walked out the option to keep the lease in force and sue for rent as it comes due, rather than terminating and chasing a lump-sum damages award. The remedy is not automatic. The lease has to opt in, and the tenant has to retain a real ability to sublet or assign the space. When those pieces line up, the landlord collects the contract rent on the contract schedule, without having to prove market value or justify mitigation efforts.
Two Paths After a Tenant Abandons
California gives a landlord two very different remedies after abandonment, and the choice between them drives everything else.
The first path is termination under Section 1951.2. The landlord ends the lease, retakes the property, and sues for damages: unpaid rent up to termination, the gap between the contract rent and reasonable rental value through trial, and a discounted estimate of the remaining term’s losses. The tenant can knock the award down by showing the landlord could have avoided some of the loss by reletting sooner.1California Legislative Information. California Civil Code 1951.2 It is one lawsuit, and the landlord has to prove the numbers.
The second path is Section 1951.4. The lease stays alive. The landlord sues for rent as each installment falls due, or waits and sues at the end of the term for the whole unpaid balance. No discounting, no market-value contest, no mitigation defense.2California Legislative Information. California Civil Code 1951.4
The remedy is most valuable when market rents have fallen below the contract rate. Terminating in that market forces the landlord into a damages fight over what the space really would have earned. Keeping the lease alive avoids that fight and pins the tenant to the original price. In a rising market, termination and reletting at the higher rate is often the better play, with the departing tenant on the hook for any gap.
Lease Language That Activates the Remedy
Section 1951.4 is opt-in. If the lease says nothing about it, the landlord is stuck with the termination-and-damages route under Section 1951.2.2California Legislative Information. California Civil Code 1951.4
The statute supplies a sample clause that satisfies the requirement, and most commercial leases that use this remedy include language closely tracking that example. It has to do two things: state the landlord’s right to continue the lease after breach and abandonment and to recover rent as it accrues, and confirm the tenant’s right to sublet or assign. A clause that invokes Section 1951.4 while flatly barring transfer creates a contradiction the court has to untangle.
Though the statute applies to real property leases generally, this remedy shows up almost entirely in commercial agreements. Residential leases rarely opt in, and residential tenancy dynamics make it a poor fit.
The Subletting and Assignment Requirement
The tenant has to have a real exit. Section 1951.4(b) recognizes three lease structures that qualify:2California Legislative Information. California Civil Code 1951.4
- The lease allows subletting or assignment without conditions.
- The lease allows subletting or assignment subject to standards that were reasonable when the lease was signed and remain reasonable when the tenant tries to transfer. Stated conditions are presumed reasonable, and the tenant bears the burden of proving otherwise.
- The lease requires the landlord’s consent, but the lease states, or the law implies, that consent cannot be unreasonably withheld.
A lease that prohibits transfer outright kills the remedy. The logic is simple: you cannot hold someone financially responsible for the space while sealing off every way out.
What Counts as Reasonable When Screening Replacements
When a lease requires landlord consent but says nothing about the standard, California law fills the gap with a reasonableness requirement. A tenant can force the issue by asking the landlord to state objections in writing; a failure to respond within a reasonable time with a specific written reason itself supports a finding that the withholding was unreasonable.3California Legislative Information. California Civil Code 1995.260
Typical reasonable grounds for refusing a proposed subtenant or assignee include poor creditworthiness, a use incompatible with the property or the other tenants, or a history suggesting the newcomer will not perform. What a landlord cannot do is invent new conditions that were not in the original lease or reject qualified applicants without saying why.
The consequences of an unreasonable refusal go beyond losing the Section 1951.4 option. The tenant gains the full set of breach-of-contract remedies, including damages and the right to terminate the lease outright.4California Legislative Information. California Civil Code 1995.310 The landlord who overreaches on consent can flip from creditor to breaching party in a single exchange.
Actions That Do Not Count as Retaking Possession
Section 1951.4 only works if the landlord does not terminate. Any conduct a court reads as retaking possession ends the lease and kills the remedy. The statute names specific acts that do not count as termination:2California Legislative Information. California Civil Code 1951.4
- Maintaining and preserving the property. Repairing a broken pipe, securing windows, keeping systems running.
- Efforts to relet. Showing the space, listing it, negotiating a sublease on the tenant’s behalf.
- Asking a court to appoint a receiver.
- Withholding consent to a proposed transfer, so long as the refusal is consistent with the tenant’s transfer rights.
These are protective moves, not possessory ones. Trouble starts when the landlord’s involvement begins to look like operating the space for the landlord’s own benefit: renovating to a different specification, using the unit for storage, or signing a new direct lease with someone else on different terms. Each of those can be read as an election to terminate. Landlords who plan to stay active with the property should document that their intent is preservation, not reclamation.
The Four-Year Window To Collect
Timing matters. The limitations period for a claim on a written contract in California is four years from the breach.5California Legislative Information. California Code of Civil Procedure 337 Each missed rent payment starts its own four-year clock. A landlord who waits until the end of a long lease to sue for the full unpaid balance may find the earliest missed payments already time-barred.
The statute permits a single end-of-term action for everything unpaid, but that only works cleanly if the remaining term is inside four years. On longer terms, filing periodically keeps every payment within the window. The tradeoff is repeated filing costs, so the choice comes down to the monthly rent, the remaining term, and how expensive repeated litigation will be.
When Bankruptcy Interrupts the Remedy
A tenant bankruptcy filing can freeze the Section 1951.4 strategy quickly. The automatic stay blocks collection of pre-petition rent, termination notices, and lawsuits for past-due amounts, and violations can trigger sanctions and attorneys’ fees.
For a commercial lease, the tenant has 120 days from the petition date to assume or reject the lease. Doing nothing within that period counts as rejection, and the tenant must surrender the space.6Office of the Law Revision Counsel. 11 USC 365 – Executory Contracts and Unexpired Leases The court can extend the deadline by 90 days for cause; anything beyond that requires the landlord’s written consent. Rent that accrues after the filing is treated as an administrative expense of the estate, but pre-petition arrears drop into the unsecured pool, where recovery is often minimal.
Insurance Consequences of a Long Vacancy
Keeping a lease alive on paper does not keep the building occupied, and standard commercial property policies treat vacancy harshly. Under the widely used ISO form, a building is considered vacant unless at least 31 percent of its total square footage is rented to a subtenant actively using the space, or is being used by the owner. An enforceable lease with an absent tenant does not meet the threshold.
Once a building has been vacant more than 60 consecutive days, the policy typically drops coverage entirely for vandalism, theft, sprinkler leakage, water damage, and glass breakage, and cuts payouts on other covered losses by 15 percent. A vacancy permit endorsement can suspend the exclusion for a set period, and some insurers will lower the 31-percent threshold by endorsement. The cost of that coverage belongs in the decision about whether keeping the lease alive is really worth more than terminating and reletting hard.
