Breaking a commercial lease in California is possible, but your financial exposure depends almost entirely on what the lease says about subletting and assignment. If your lease allows either (even with the landlord’s consent), Civil Code Section 1951.4 lets the landlord sit back, keep the lease alive, and bill you for the full remaining rent without ever looking for a replacement tenant. If the lease prohibits transfer, the landlord must try to re-lease and credit what it collects against your debt. Before you do anything else, figure out which category your lease falls into.
Read the Lease Before You Do Anything
Your lease is the first place to look for a legitimate exit. Several clauses commonly do the work:
- An early termination or buyout clause sets the notice period and the fee for ending the lease early. The fee is often several months’ rent or a declining percentage of the remaining rent obligation.
- A break clause allows either party to terminate after a set period, often at the midpoint of the term, with advance notice and sometimes a penalty.
- A co-tenancy clause, common in retail, lets you terminate or renegotiate rent if an anchor tenant leaves or overall occupancy drops below a threshold.
- Assignment and sublease provisions may not end the lease, but they give you a practical exit by handing the space to someone else.
Read the notice requirements carefully. Many termination clauses require written notice 60 to 180 days in advance, and missing the window can lock you in for another full term.
The Section 1951.4 Trap
Most tenants assume that if they vacate, the landlord has to make a reasonable effort to re-lease and the original tenant only owes the gap. That assumption is wrong for most California commercial leases.
Under Civil Code Section 1951.4, if your lease allows you to sublet or assign your interest, the landlord can choose not to terminate when you leave. The landlord keeps the lease in place and collects rent as it comes due for the entire remaining term, with no obligation to look for a replacement.1California Legislative Information. California Code CIV 1951.4
Section 1951.4 is triggered when the lease:
- Permits subletting or assignment without restriction, or
- Permits subletting or assignment subject to standards or conditions that were reasonable when the lease was signed, or
- Requires the landlord’s consent for a transfer, and either the lease says that consent will not be unreasonably withheld or the law implies that standard.
That last point sweeps in most leases. Under Civil Code Section 1995.260, if your lease requires the landlord’s consent for a transfer but doesn’t specify any standard for granting or denying it, California law reads in an implied standard that consent cannot be unreasonably withheld.2California Legislative Information. California Code CIV 1995.260 That implied standard alone is enough to trigger Section 1951.4.
The practical result: in the vast majority of California commercial leases, the landlord has no legal duty to mitigate. If you walk away from a five-year lease with three years remaining at $8,000 a month, the landlord can potentially collect the full $288,000 from you without lifting a finger to find another tenant. The landlord might re-lease the space anyway, but as a business decision, not a legal one. Before you vacate, determine whether your lease triggers Section 1951.4. If it does, your realistic options narrow to finding a replacement tenant yourself or negotiating a buyout.
Legal Grounds to Terminate
Even without a termination clause, California law recognizes a handful of situations where a tenant can end a commercial lease early. All of them are narrower than tenants expect.
The Landlord’s Material Breach
If the landlord fails to perform a significant obligation under the lease, that failure can justify termination. The breach must be material. A landlord who refuses to provide essential utilities, declines to make structural repairs the lease requires, or denies access to common areas is breaching in a way that goes to the core of the deal. A slow response to a cosmetic maintenance request is not. Document the breach, give the landlord written notice, and allow a reasonable opportunity to cure. If the lease specifies a cure period, follow it exactly.
Constructive Eviction
Constructive eviction occurs when the landlord’s actions or inaction make the space so unsuitable for its intended purpose that you’re effectively forced out. Persistent flooding, hazardous conditions, or a complete loss of heating or cooling could qualify. Two things make this harder in commercial leases than in residential ones. First, you generally must actually vacate; you cannot stay, continue operating, and later claim constructive eviction. Second, many commercial leases limit the tenant’s remedies to damages or an injunction and explicitly take away the right to terminate. California’s covenant of quiet enjoyment, codified in Civil Code Section 1927, can be waived or modified by agreement in a commercial lease. Check your lease for that kind of limitation before relying on this theory.
Frustration of Purpose and Impossibility
Frustration of purpose applies when an unforeseen event destroys the entire reason the lease existed, like a new regulation that bars the specific business the space was leased for. California courts apply the doctrine narrowly. The event must have been unforeseeable and must destroy the whole value of the lease, not just make the business harder or less profitable. A tenant who leased space for a restaurant later barred by a zoning change might have a claim; a tenant whose sales fell in a recession would not. Courts also require that the tenant actually surrender the premises.
Impossibility of performance requires that an unforeseen event make performance literally impossible. Destruction of the building by earthquake or fire is the clearest example. Financial inability to pay rent, even caused by events outside your control, doesn’t qualify.
Military Service
The federal Servicemembers Civil Relief Act, at 50 U.S.C. § 3955, reaches commercial leases of premises used for a professional, business, or agricultural purpose. A servicemember may terminate after entering military service, receiving permanent change of station orders, or receiving deployment orders of 90 days or more, by delivering written notice with a copy of the orders. The landlord cannot charge an early termination fee.3Office of the Law Revision Counsel. 50 USC 3955 – Termination of Residential or Motor Vehicle Leases If a landlord pressures you to sign a waiver of SCRA rights, consult a military legal assistance office before signing anything.
Negotiating an Exit
When the lease gives you no clean termination right and you have no legal justification, negotiation is usually your best path. Landlords often prefer a negotiated exit to the cost and uncertainty of chasing a departed tenant.
Buying Out the Lease
A buyout is a lump-sum payment in exchange for the landlord releasing you from the remaining obligations. The number typically reflects the landlord’s expected losses: rent during the vacancy, brokerage commissions to find a replacement, and concessions (free rent, buildout allowances) a new tenant will demand. In a strong rental market where the space can be re-leased quickly at a higher rate, you have leverage. In a weak market, expect to pay more. Get the buyout agreement in writing and make sure it includes a full release of liability, including any personal guarantee.
Finding a Replacement Tenant
Presenting the landlord with a qualified, financially stable replacement is often the single most effective move. The goal is a direct lease between the new tenant and the landlord, not a sublease where you remain on the hook. If your lease requires the landlord’s consent for an assignment and doesn’t specify a standard, California law implies that consent cannot be unreasonably withheld.2California Legislative Information. California Code CIV 1995.260 A landlord who rejects a reasonable candidate without a good reason bears the risk of a court finding the refusal unreasonable. Come prepared with the prospective tenant’s financial statements, business plan, and references. The easier you make the decision, the faster you’re out.
What You’ll Owe If You Just Leave
If you vacate without a release or a legal justification, your exposure depends on which statute controls.
When Section 1951.2 Applies
If your lease prohibits or heavily restricts subletting and assignment, Section 1951.4 doesn’t apply and Civil Code Section 1951.2 governs instead. Once you vacate, the lease terminates and the landlord can recover unpaid rent earned before termination with interest, lost rent from termination through trial minus what the landlord could have reasonably avoided by re-leasing, lost rent for the remainder of the term (also minus avoidable losses, discounted to present value), and other damages caused by the breach, including advertising, brokerage, and buildout costs.4California Legislative Information. California Code CIV 1951.2
The landlord can only recover future rent after trial if the lease specifically allows it or the landlord actually re-leased in good faith before trial. The burden sits on the tenant to prove the landlord could have avoided some of the losses; the landlord doesn’t have to prove it tried. Keep evidence that comparable space in the area was in demand and that the landlord passed on reasonable opportunities.
When Section 1951.4 Applies
If the lease permits transfer in any of the ways described earlier, the landlord skips mitigation entirely, leaves the lease in place, and collects rent as it comes due.1California Legislative Information. California Code CIV 1951.4 The logic is that the tenant had the ability to find a subtenant or assignee and chose not to use it. The gap between the two statutes can be enormous, which is why identifying which one applies is the single most important step in sizing your risk.
Personal Guarantees
Many commercial leases require the business owner to personally guarantee the lease. If you signed one, breaking the lease puts your personal assets at risk, not just the business’s. Rejection of the lease, including through bankruptcy, does not automatically release a guarantor. Factor that into every calculation about whether to walk.
The Security Deposit
Civil Code Section 1950.7 governs commercial security deposits. After you surrender the premises, the landlord can deduct amounts reasonably necessary for unpaid rent, tenant-caused damage, and cleaning. Any balance must be returned within 30 days of the landlord receiving possession. If the landlord retains your deposit in bad faith, you can recover actual damages plus up to $200 in statutory penalties.5California Legislative Information. California Civil Code 1950.7
How to Actually Terminate
However you exit, documentation protects you from later disputes.
Written Notice
Deliver a formal written notice stating the termination date, the specific reason (referencing the lease clause or legal ground), and your forwarding address for return of the security deposit. Deliver it exactly as the lease’s notice clause requires. If the lease doesn’t specify, use certified mail with return receipt requested. Keep copies of everything.
Surrender Agreement
If you negotiate a buyout or early release, insist on a written surrender agreement that explicitly releases you from all future rent obligations. It should address the security deposit, any personal guarantee, the condition in which you’ll return the space, and a mutual release of claims. Without it, a landlord could accept your payment and later argue you’re still on the hook for the remainder of the term.
Abandonment
If you simply stop paying and leave without notice, the landlord can start a formal abandonment process. Under Civil Code Section 1951.35, the landlord may serve a notice of belief of abandonment once rent has been unpaid for at least the number of days required to declare a default under the lease (and no fewer than three days). The notice gives you at least 15 days to respond in writing that you haven’t abandoned the space.6California Legislative Information. California Code CIV 1951.35 If you don’t respond, the lease terminates and the landlord’s damage claim under Section 1951.2 begins. Leaving quietly doesn’t reduce your liability; it just adds the landlord’s costs of determining you’ve left.
Bankruptcy as a Last Resort
Filing for bankruptcy doesn’t erase your lease obligations, but it changes the rules. The petition triggers the automatic stay under 11 U.S.C. § 362, which halts collection, eviction, and demands for pre-petition rent.7Office of the Law Revision Counsel. 11 USC 362 – Automatic Stay Under 11 U.S.C. § 365, the trustee or debtor-in-possession can assume or reject the lease, subject to court approval.8Office of the Law Revision Counsel. 11 USC 365 – Executory Contracts and Unexpired Leases In Chapter 7, the trustee has 60 days from filing to decide, or the lease is automatically rejected. In Chapter 11, the decision can wait until plan confirmation, though the landlord can ask the court to impose a deadline.
Rejection treats the lease as breached as of the moment before filing. The landlord still has a damages claim, but federal law caps it. Under 11 U.S.C. § 502(b)(6), the landlord can recover any unpaid rent already due plus the greater of one year’s rent or 15 percent of the remaining lease term, capped at three years of rent. For a tenant stuck under a long-term lease, that cap can slash total exposure. Rejecting the lease, however, does not release personal guarantors.
How Long the Landlord Has to Sue
Under California Code of Civil Procedure Section 337, the landlord has four years from the date of breach to sue for damages on a broken commercial lease.9California Legislative Information. California Code of Civil Procedure 337 The clock starts when you vacate and stop paying. Silence from your former landlord doesn’t mean you’re in the clear. Landlords sometimes wait to see how long the space sits vacant before filing, because a longer vacancy means larger provable damages. If you broke a lease without a written release, keep your records and stay prepared for a claim within that four-year window.
