What follows is our general observations and opinions. It is not legal advice, and it is not a definitive statement of California law. Every situation depends on its own facts.
The first thing to understand about a commercial security deposit is that the residential rules you may have heard of do not apply to it. The statutory protections that cap a residential deposit, restrict what it can be used for, and impose a deadline for its return are residential doctrines. In a commercial lease, our reading is that the deposit is governed by what the lease says — which means the lease language is not a formality, it is the entire protection.
The second thing is that a landlord asking for six months of rent as a deposit, or a letter of credit, is not necessarily being unreasonable. They are pricing credit risk. The useful response is rarely to refuse outright; it is to negotiate the size, the form, and above all the conditions on which the money comes back.
Deposit, letter of credit, or guarantee
These three get discussed as if they were interchangeable. They are not, and the differences matter to both sides.
- A cash deposit is simple and it ties up your working capital. It also sits with the landlord, which becomes a live question if the landlord’s own financial position deteriorates.
- A letter of credit is issued by your bank and drawn on by the landlord. It usually requires you to post collateral with the bank, so the capital is still committed, and it carries annual issuance fees. Its advantage is that it generally sits outside the landlord’s estate if the landlord becomes insolvent, which is precisely why institutional landlords prefer it.
- A personal or parent guarantee commits someone else’s assets instead of cash. It costs nothing up front, which is exactly why tenants underestimate it.
In our experience the right negotiation is frequently about the mix rather than the amount — a smaller deposit paired with a capped guarantee is often more achievable than arguing the headline number down.
What the deposit can actually be applied to
Commercial leases typically allow the landlord to apply the deposit to unpaid rent, to the cost of repairing damage beyond ordinary wear, and to any other sum the tenant owes under the lease. That last phrase is broad, and it is worth reading carefully, because it frequently sweeps in operating expense reconciliations, attorney fees and restoration costs.
Two provisions worth pushing on. The first is a replenishment obligation — a clause requiring the tenant to top the deposit back up within a short period after any draw. It is standard, but the period is negotiable and a five-day window is unhelpfully tight. The second is the question of whether the landlord must give notice before drawing. Many forms allow a draw without notice, and a tenant who discovers the draw only through a replenishment demand has lost the chance to dispute the underlying charge.
The burn-down is where the value is
If there is one provision we would prioritize, it is the burn-down: a clause reducing the deposit or letter of credit over time as the tenant establishes a payment history. A ten-year lease with an unchanging six-month deposit has capital sitting idle for a decade.
A workable burn-down needs four things settled. The trigger — usually the passing of a defined number of lease months. The conditions — commonly that no monetary default has occurred, and we would push to narrow that to no uncured monetary default, since a payment made two days late should not permanently forfeit the reduction. The mechanics — who does what, and by when, because a burn-down that requires the landlord to affirmatively consent can sit unactioned. And the schedule itself, which should be written into the lease as dates and figures rather than left to later agreement.
We would also ask what happens on assignment. A burn-down earned by the original tenant frequently resets on transfer, which matters if the business is likely to be sold.
Letter of credit mechanics that catch tenants out
A letter of credit adds a third party, and the third party has its own requirements.
Watch the expiry. Letters of credit are typically issued for a year with automatic renewal, and the issuing bank must give notice if it will not renew. Leases generally provide that a failure to deliver a renewal a defined period before expiry entitles the landlord to draw the full amount immediately. That is a calendar obligation that outlives whoever negotiated the lease, and in our experience it is the single most common way a solvent tenant loses its collateral — nobody diarized the date.
Watch the transfer provisions too. If the building is sold, the letter of credit has to be transferred to the new landlord, and banks charge a fee for that. The lease should say who pays it.
Finally, watch the draw conditions. A letter of credit is usually drawable on the landlord’s written statement that it is entitled to draw. The bank does not investigate whether that statement is true. A tenant who believes the draw was improper is left arguing about it after the money has gone, which is a materially weaker position than arguing about it beforehand.
Getting it back at the end
The end of the term is where disputes cluster, and usually around restoration. If the lease requires the tenant to remove its alterations and return the premises to base building condition, the cost of that work can exceed the deposit. The time to address it is at lease signing, by agreeing in writing which alterations may remain — a landlord frequently prefers to keep a good build-out rather than pay to have it torn out.
Practically, we suggest a tenant walk the space with the landlord before surrender, photograph the condition on the day keys are handed over, and ask for a written itemization of any deductions rather than a net figure. A commercial landlord is generally not under the residential itemization obligations, but most will provide the detail if it is requested politely and early, and a request that goes unanswered is itself useful later.
The Los Angeles context
Deposit demands here have been noticeably firmer for tenants without a long trading history, and for uses that involve significant build-out — restaurants, medical and fitness, where restoration exposure is real. On older low-rise stock the landlord is frequently a private owner rather than an institution, which cuts both ways: there is usually more flexibility on the structure, and more reason to care about where a cash deposit is actually held.
How we work on these
Reviewing and negotiating lease security provisions is hourly or flat-fee work, and we normally quote a flat fee where it forms part of a wider lease review. This is transactional work rather than contingency work and we would not describe it as anything else. Getting a burn-down and a sensible set of draw conditions into the lease at the outset costs a fraction of what it costs to argue about a drawn letter of credit afterwards.
