Break a commercial lease in Los Angeles three years into a ten-year term and the exit penalty can easily top six figures. Not because the landlord wants to punish you — because they spent real money fitting out your space. Tenant improvement allowances in premium office markets like Century City and Santa Monica typically run $40 to $80 per square foot. On a 5,000-square-foot office, that is £200,000 to £400,000 the landlord fronted and expects to recoup over the full lease term. Leave early and you still owe that unamortised balance.

Lease exit penalties in California are not arbitrary fines. They are calculated damages designed to put the landlord in the position they would have been in had the lease run its course. The mechanics vary by market, by lease structure, and by how much leverage the tenant has. What I tend to notice is that tenants focus on the monthly rent and overlook the real cost drivers — the unamortised broker commissions, the free rent periods, and the fit-out costs the landlord already paid. That gap between what tenants expect and what they owe is where the surprises live. Here is what you actually need to know.
What You Will Learn About Lease Exit Penalties
Before going further, one term comes up constantly in lease exit discussions. Liquidated damages are a pre-agreed estimate of the landlord’s loss if you break the lease early. Courts enforce them only if the amount was reasonable at the time of signing — not an inflated figure disguised as a penalty.
My first move if I were facing an exit negotiation would be to dig out the lease and check whether it has a liquidated damages clause or a termination option with a formula. The difference between the two can change the exit cost by tens of thousands of dollars.
The Full Cost Breakdown of an Early Lease Exit
The headline figure most tenants focus on is the remaining rent — but the termination fee usually includes several other items the landlord spent upfront. Understanding each component is the difference between accepting a calculated figure and challenging one. Landlords rarely itemise these voluntarily.

| Cost Component | What It Covers | Typical Range |
|---|---|---|
| Unamortised broker commissions | Commission paid upfront to the agent who secured your lease; recouped over the lease term | 4–8% of total lease value |
| Unamortised tenant improvements | Fit-out, construction, and build-out costs the landlord paid at lease commencement | $40–80 per sq ft in premium LA markets |
| Unamortised free rent and concessions | Rent-free periods or reduced rent offered as a lease incentive; now being reclaimed | 3–12 months of rent |
| Lost rent during vacancy | Rent from the exit date until a new tenant moves in and starts paying | Varies by market conditions |
| Legal and re-leasing costs | Attorney fees for the termination and costs to market and re-lease the space | Often covered in lease or statute |
The mix matters. A tenant who negotiated a large improvement allowance and several months of free rent at the start will face a much higher exit penalty than one who took a “plain vanilla” lease with minimal concessions. What I’d be weighing here is whether the termination clause in the lease uses a straight-line amortisation or a accelerated schedule, because that changes how fast the balance drops each year.
Common Mistakes Tenants Make With Lease Exit Penalties
Treating the penalty as a fixed number
Many tenants assume the termination fee printed in the lease is what they must pay, full stop. It is not. California law gives landlords a duty to mitigate damages — they must try to re-lease the space. If a new tenant moves in two months after you leave, your liability for lost rent ends there. The lease may say you owe the full remaining term, but the law caps it at what the landlord actually loses after reasonable efforts. Ask for proof of those efforts before writing a cheque.
Ignoring the difference between a termination option and a default
Breaking a lease through a termination option — where the lease gives you a unilateral right to exit for a set fee — is entirely different from defaulting. Default triggers the notice and cure periods, and the landlord can pursue the full California Civil Code 1951.2 damages: future rent, difference in rent, leasing costs, and attorney fees. The option route usually costs less and avoids the legal machinery, but most tenants do not realise they may already have this right buried in the lease. Check every addendum.
Not considering the natural disaster angle in California
Los Angeles commercial leases increasingly include earthquake and wildfire termination triggers. After major seismic events or fires, tenants may have the right to exit without penalty if the building is damaged beyond a defined threshold or restoration takes longer than a set period. But here is the catch — the trigger must be written into the lease. Standard force majeure clauses often do not cover earthquakes specifically. If you signed a lease without a clear disaster termination clause, you could be stuck paying rent on an unusable space.
Overlooking the implied covenant of good faith
California courts recognise an implied covenant of good faith and fair dealing in commercial leases. That means a landlord cannot unreasonably withhold consent to a sublet or assignment just to maximise your exit cost. If you find a creditworthy replacement tenant and the landlord blocks it without a legitimate reason, a court may not enforce the full penalty. This is worth knowing early — it changes your negotiating position. I have seen tenants settle for a fraction of the original demand once they showed the landlord they understood this.
How to Handle an Early Lease Exit Properly
Audit your termination rights first
Before doing anything else, pull the full lease — including every amendment, addendum, and side letter. Look for a section titled “Termination Option,” “Early Termination,” or “Buyout.” If it exists, it will specify the notice period, the fee formula, and whether the option is exercisable at any time or only at specific dates (commonly year five or seven in premium submarkets). If no such clause exists, you are in the default framework, which means the landlord can claim full California Civil Code 1951.2 damages. At this point, it is worth speaking with someone who works through these leases regularly — a legal service with real estate experience can often spot language you would miss.
Calculate the unamortised balance yourself
Do not rely on the landlord’s first invoice. Ask for a full accounting: the original broker commission, the tenant improvement draw, the total free rent and concessions granted — and the amortisation schedule used. Straight-line amortisation (equal portions each year) is the most common. An accelerated schedule (larger portions early) works against you if you leave early. Verify the start date of the term and the date of your exit. The difference is the amortised period. The remainder is what you potentially owe.
Explore alternatives before notifying the landlord
A direct termination is not the only route. Three alternatives often reduce the total cost:
- 1Sublet the spaceFind a subtenant to take over the lease. You remain ultimately liable if the subtenant defaults, but the landlord gets paid and your exposure drops significantly. Most leases allow subletting with the landlord’s reasonable consent.
- 2Assign the leaseA full assignment transfers all rights and obligations to a new tenant. You walk away entirely. Landlords can refuse assignment, but unreasonable refusal violates the implied covenant of good faith and fair dealing.
- 3Negotiate a mutual terminationPropose a clean break: you pay a negotiated amount and the landlord releases you from all future obligations. This is often cheaper than the formula in the lease because the landlord avoids vacancy risk and gets cash immediately.
Put everything in writing
Verbal agreements are not enforceable for lease modifications. Any exit deal — whether a mutual termination, a sublet approval, or a payment plan — must be documented in a signed amendment. Include the exact amount, the release of liability, and any conditions. The same applies if you are responding to a default notice. California requires strict notice timelines: three days to pay rent or quit for monetary defaults, and three days to perform or quit for non-monetary breaches. Accepting rent after a default can waive the landlord’s right to enforce it — but do not rely on that. Deliver written notice of your position and keep copies.

Why Getting the Exit Right Matters More Now
Commercial lease structures in Los Angeles have grown more sophisticated, particularly in premium submarkets. Termination options are becoming more restrictive, and landlord-friendly amortisation schedules are standard. At the same time, California law still gives tenants meaningful protections — the duty to mitigate, the limits on liquidated damages, and the implied covenant of good faith — that many landlords do not advertise. The difference between a well-managed exit and a reactive one is often tens of thousands of pounds and the difference between a clean break and a protracted legal dispute.
