Breaking a commercial lease in California is possible, but rarely cheap. Your exit route depends on three things: what your lease says, whether the landlord has broken the agreement, and — most importantly — whether California Civil Code Section 1951.4 applies to your lease. That last question decides whether the landlord has to try to re-lease the space or can simply keep billing you rent for the entire remaining term.
Read Your Lease First
Before anything else, look for a clause that already gives you a way out:
- An early termination or buyout clause that sets a notice period and a fee, often several months’ rent or a declining percentage of the remaining rent.
- A break clause allowing either party to end the lease at a set point in the term with advance notice.
- A co-tenancy clause (common in retail) that lets you terminate or renegotiate if an anchor tenant leaves or occupancy drops below a threshold.
- Assignment and sublease provisions, which may not end the lease but give you a practical exit by handing it to someone else.
Read the notice requirements closely. Many termination clauses require written notice 60 to 180 days in advance, and missing that window can lock you in for another year.
The Section 1951.4 Question That Decides Everything
Most tenants assume that if they leave, the landlord has to make a reasonable effort to re-lease and they only owe the gap. That assumption is right under one California statute and wrong under another.
Under Civil Code Section 1951.4, if your lease allows you to sublet or assign your interest — even with the landlord’s consent — the landlord can choose to keep the lease alive after you leave and collect rent from you as it comes due for the entire remaining term, with no obligation to look for a replacement tenant.1California Legislative Information. California Code CIV 1951.4
Section 1951.4 applies when any of these is true:
- The lease permits subletting or assignment without restriction.
- The lease permits subletting or assignment subject to standards or conditions that were reasonable when the lease was signed.
- The lease requires the landlord’s consent for subletting or assignment, and either the lease states consent won’t be unreasonably withheld, or the law implies that standard.
That third point catches almost everyone. Under Civil Code Section 1995.260, if your lease requires the landlord’s consent but doesn’t specify a standard for granting or denying it, California 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 most commercial leases, the landlord has no legal duty to mitigate. Walk away from a five-year lease with three years remaining at $8,000 per month, and the landlord can potentially collect the full $288,000 without lifting a finger to find a new tenant. The landlord may still re-lease. That’s a business choice, not a legal requirement. If your lease triggers Section 1951.4, your realistic options narrow to finding a replacement tenant yourself or negotiating a buyout.
Legal Grounds to Terminate Without a Buyout
Even without a termination clause, California recognizes a few situations where you can end a commercial lease early.
The Landlord Materially Breached the Lease
If the landlord fails to fulfill a significant obligation, that failure can justify termination. The breach must be material. A landlord who won’t provide essential utilities, refuses required structural repairs, 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 repair is not. Document the breach, give written notice, and provide a reasonable opportunity to cure. If the lease sets a cure period, follow it exactly.
Constructive Eviction
Constructive eviction happens when the landlord’s acts or failures make the space so unsuitable for its intended use that you’re effectively forced out. Persistent flooding, hazardous conditions, or complete loss of heating or cooling can qualify. Two things make this harder to prove in a commercial context than in a residential one. First, you generally must actually vacate; you cannot stay, keep operating, and then claim constructive eviction. Second, many commercial leases limit the tenant’s remedies to damages or injunctive relief, cutting off the right to terminate. California’s covenant of quiet enjoyment under Civil Code Section 1927 can be waived or modified by agreement in a commercial lease, so check your lease before relying on this theory.
Frustration of Purpose
This applies in rare situations where an unforeseen event destroys the entire reason the lease existed. A zoning change that bars the specific business the space was leased for could qualify. A recession that hurts sales does not. Courts apply the doctrine narrowly, and the tenant must actually surrender the premises to claim relief.
Impossibility of Performance
Impossibility requires that an unforeseen event make performance literally impossible, not just difficult or expensive. Destruction of the building by earthquake or fire is the clearest example. Financial inability to pay rent, however caused, does not qualify.
Negotiating an Exit
When the lease gives you no clean termination right and you don’t have legal grounds, negotiation is usually the best path. Landlords often prefer a negotiated exit to chasing a departed tenant for unpaid rent.
Lease Buyout
A buyout is a lump-sum payment in exchange for a release from the remaining lease obligations. The amount typically covers the landlord’s expected losses: lost rent during vacancy, brokerage commissions to find a replacement, and any concessions (free rent, buildout allowances) a new tenant will demand. In a strong rental market where the landlord can re-lease quickly at a higher rate, you have leverage. In a weak market, expect to pay more. Get the buyout in writing, and make sure it includes a full release of liability, including any personal guarantee.
Bring a Replacement Tenant
Presenting a qualified, financially stable replacement is often the most effective tool you have. Aim for a direct lease between the new tenant and the landlord, not a sublease that leaves you liable. 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 Come prepared with the prospective tenant’s financial statements, business plan, and references. The easier you make the decision, the faster you get out.
What It Costs If You Just Leave
If you vacate without a negotiated release or legal justification, your exposure depends on which statute governs.
When Section 1951.2 Applies
If your lease does not trigger Section 1951.4 — meaning it prohibits or heavily restricts subletting and assignment — then Section 1951.2 governs. Once you vacate, the lease terminates and the landlord can recover:
- Unpaid rent earned before termination, plus interest.
- Lost rent from termination through trial, minus what the landlord could reasonably have avoided by re-leasing.
- Lost rent for the remaining term after trial, minus avoidable losses, discounted to present value using the Federal Reserve Bank of San Francisco discount rate plus one percent.
- Other damages caused by the breach, including advertising, brokerage fees, and buildout expenses.
The landlord can only recover future rent (the third category) if the lease specifically allows it or the landlord actually re-leased the space in good faith before trial.3California Legislative Information. California Code CIV 1951.2 The burden is on you, the tenant, to prove the landlord could have avoided some of the losses. You’ll want evidence that comparable space was in demand and that the landlord passed on reasonable opportunities to re-lease.
When Section 1951.4 Applies
If the lease permits subletting or assignment in any of the forms above, the landlord can skip mitigation entirely. The lease stays in place, and the landlord collects rent as it comes due.1California Legislative Information. California Code CIV 1951.4 The reasoning: you had the tools to find a subtenant or assignee and chose not to use them. The gap between the two statutes can be enormous, which is why identifying which one applies is the first thing to do before you make any move.
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 on the line, not just the business’s. Bankruptcy of the tenant entity does not automatically release a guarantor. Factor this into every calculation about whether to walk.
Security Deposit
Civil Code Section 1950.7 governs commercial security deposits. After you surrender the space, the landlord may 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. A landlord who retains the deposit in bad faith is liable for actual damages plus up to $200 in statutory penalties.4California Legislative Information. California Civil Code 1950.7
Bankruptcy as a Last Resort
Filing bankruptcy doesn’t erase lease obligations, but it changes the rules. The petition triggers an automatic stay under 11 U.S.C. § 362, which halts collection actions, eviction proceedings, and demands for pre-petition rent.5Office of the Law Revision Counsel. 11 USC 362 – Automatic Stay
Under 11 U.S.C. § 365, the trustee or debtor-in-possession may assume or reject the lease, subject to court approval.6Office of the Law Revision Counsel. 11 USC 365 – Executory Contracts and Unexpired Leases Rejection treats the lease as breached immediately before the filing date. Federal bankruptcy law then caps the landlord’s damages: under 11 U.S.C. § 502(b)(6), the claim is limited to 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 buried under a long-term lease, that cap can slash total exposure. Rejection does not release personal guarantors.
How to Terminate the Right Way
However you leave, documentation protects you from future disputes.
Written Notice
Deliver a formal written notice of termination that states the termination date, the specific reason (referencing the lease clause or legal ground you’re relying on), and your forwarding address. Deliver it exactly as the lease’s notice clause requires. If the lease is silent, use certified mail with return receipt requested. Keep copies of everything.
Abandonment
If you stop paying and leave without notice, the landlord can start a formal abandonment process. Under Civil Code Section 1951.35, once rent has been unpaid for at least the number of days required to declare default (no fewer than three), the landlord may serve a notice of belief of abandonment giving you at least 15 days to respond in writing that you haven’t abandoned the space.7California Legislative Information. California Code CIV 1951.35 No response, and the lease terminates and the landlord’s damage claim begins. Leaving quietly does not reduce liability; it adds the landlord’s costs of figuring out whether you’ve gone.
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 this, a landlord could accept your buyout and later claim you still owe the remaining term.
If You Are a Military Servicemember
The federal Servicemembers Civil Relief Act reaches commercial leases. Under 50 U.S.C. § 3955, the SCRA covers leases of premises used for a professional, business, or agricultural purpose. A servicemember may terminate a qualifying lease after entering military service, receiving permanent change of station orders, or receiving deployment orders for 90 days or more. Deliver written notice with a copy of the orders by hand, private carrier, or U.S. mail return receipt requested. For monthly-rent leases, termination takes effect 30 days after the next rent payment is due following notice. The landlord cannot charge an early termination fee, and any prepaid rent for the period after termination must be refunded within 30 days.8Office of the Law Revision Counsel. 50 USC 3955 – Termination of Residential or Motor Vehicle Leases SCRA rights can technically be waived, but doing so is almost never advisable. If a landlord pressures you to sign a waiver, consult a military legal assistance office first.
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 written commercial lease.9California Legislative Information. California Code of Civil Procedure 337 The clock starts when you vacate and stop paying. Silence from a former landlord doesn’t mean you’re safe. Some 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 ready for a claim inside that four-year window.
