Security Deposits vs. Letters of Credit (LOC): What Tenants Should Know

A cash security deposit ties up money but is simple; a letter of credit preserves cash but adds bank fees, renewal traps, and "pay first, fight later" draw risk — and for most tenants, the terms matter more than the form. Whichever you provide, the protections that actually decide the cost are the same four: a limited list of permitted uses, notice-and-cure before any application or draw, defined return timing with itemization, and step-downs that shrink the security as you perform.

Commercial landlords want security. Tenants want flexibility. In practice, that security usually takes one of two forms:

a cash security deposit, or
a letter of credit (LOC) issued by a bank

Both can be expensive if the lease is drafted broadly. This guide explains how each works, the tenant risks to watch for, and the negotiation points that keep “security” from turning into a hidden cost.

What a commercial security deposit typically covers

A security deposit is a payment required by a landlord to secure the tenant's performance — paying rent on time and keeping the premises in good condition (Cornell LII). In commercial leases, it's cash held by the landlord (or sometimes an escrow agent), and the lease usually lets the landlord apply it to:

unpaid rent (base rent and “additional rent” like CAM/taxes/insurance)
late fees and interest
repairs for tenant-caused damage
removal of abandoned property
sometimes: any “losses” the landlord claims from a default

Unlike many residential settings, commercial deposit handling rules vary widely by location and lease language. Do not assume:

the deposit must earn interest
the deposit must be kept in a separate account
the landlord must return it quickly

If you want those protections, they generally need to be in the lease.

What a letter of credit is (and why it can be riskier than it sounds)

A letter of credit is an instrument issued by a financial institution — usually a bank — that authorizes the beneficiary to demand payment up to a stated amount (Cornell LII); in the lease context, the landlord is the beneficiary and draws if the LOC's conditions are met. Letters of credit are governed by Article 5 of the Uniform Commercial Code, and a core feature of that framework is that the bank's payment obligation is largely independent of the underlying lease dispute.

Key concept: many LOCs function like “pay on demand.” Depending on the wording, the bank may pay the landlord based on the landlord’s certification alone — before any dispute is resolved.

Even if you think the draw is wrongful, you may end up in a “pay first, fight later” situation:

the landlord draws on the LOC
the bank pays the landlord
the bank seeks reimbursement from you under your LOC agreement

That doesn’t mean LOCs are always bad. It means the draw conditions and notice/cure language matter a lot.

Pros and cons (tenant view)

Cash security deposit

Pros

simple and familiar
no bank paperwork or annual LOC fees
doesn’t tie up your credit line

Cons

ties up cash you could use for buildout, inventory, marketing
return timing can be slow
landlord may try to “net” the deposit against disputed amounts

Letter of credit (LOC)

Pros

preserves cash (but not always: bank may require collateral)
can sometimes be reduced over time with good payment history
clearer exit process if return conditions are defined

Cons

annual fees and bank requirements
renewal/expiration pitfalls (automatic draw if you don’t renew on time)
potential “pay now” draw risk

Tenant protections to ask for (deposit or LOC)

1) A clear, limited list of permitted uses

Avoid “for any losses landlord suffers” language. Push for:

deposit/LOC can be applied only to amounts actually due under the lease
landlord must provide a written itemization of any application

2) Notice and cure before any application/draw

If the landlord can apply the deposit or draw on the LOC immediately, you can lose leverage in a dispute.

Tenant-friendly language typically requires:

written notice of the claimed default
the lease cure period to run and expire
then (and only then) application or draw for the stated amount

3) Return timing and process

Define when security is returned after moveout:

within X days after surrender and final reconciliation
landlord must provide an itemized statement of deductions
landlord must return the unused balance promptly

4) Step-downs (reduce security after good performance)

If you’re paying on time, security should often reduce over time. Examples:

deposit reduces by 25% after 12 months with no defaults
deposit reduces after you hit a sales threshold or profitability metric (retail)
deposit converts to a smaller amount after you provide financials for 2 years

Step-downs are especially valuable if you’re also providing a personal guarantee (see personal guarantee burn-offs).

LOC-specific “gotchas” to negotiate

If the landlord insists on an LOC, focus on these details:

1) Draw conditions (make them objective)

Try to avoid “beneficiary certifies it is entitled to draw” with no details.

A more tenant-friendly structure:

landlord certification must identify the default, amount, and that cure periods have expired
draw amount limited to amounts actually due (or a defined cap for damages)

2) Notice to tenant of any draw

Ask for:

advance written notice (when feasible), and
immediate notice after any draw, with backup calculations

3) Renewal/expiration mechanics

Some leases allow the landlord to draw the full LOC if:

you don’t deliver a replacement LOC X days before expiry, or
the bank’s rating changes

If that language exists, negotiate:

longer replacement windows
objective bank standards
partial draw rights only (not automatic full draw)

4) Return of LOC at end of term

Spell out:

how quickly the landlord must return the original LOC
that the landlord must provide written release of the LOC
that no draw is permitted after surrender unless the landlord has a documented claim within a defined window

A practical question to ask before you choose deposit vs LOC

Ask your bank (or treasury team):

Will the LOC reduce my borrowing capacity?
Does the bank require cash collateral?
What are the annual fees and renewal requirements?

If the LOC effectively becomes “cash collateral + fees,” it may not be better than a deposit.

How BizLeaseCheck helps

BizLeaseCheck flags security clauses and related risks — overly broad draw/application rights, missing notice/cure protections, auto-draw triggers on LOC expiration, and missing return timelines and itemization requirements — with the exact wording quoted back to you.

Frequently asked questions

Can the landlord draw on my letter of credit even if I dispute the default?

Often, yes — that's the structural risk. Under the letter-of-credit framework, the bank pays against the documents the LOC requires (typically the landlord's certification), not against the merits of the lease dispute (UCC Article 5). Exceptions for fraudulent draws exist but are narrow and hard to invoke in time. Your practical protection is negotiated up front: objective draw conditions, notice-and-cure before any draw, and draw amounts limited to sums actually due.

Is a letter of credit cheaper than a cash deposit?

Not automatically. The LOC carries annual bank fees, and many banks require collateral — sometimes cash collateral — or count the LOC against your credit line. If your bank requires 100% cash collateral, you've tied up the same cash and added fees and renewal mechanics. Ask the bank the three questions above before agreeing; for some tenants the deposit is genuinely cheaper.

Do commercial security deposits have the same protections as residential ones?

No — and this surprises many first-time commercial tenants. The interest, separate-account, itemization, and prompt-return rules many states impose on residential deposits often don't apply (or apply differently) to commercial leases, where the lease language largely controls. If you want interest, a return deadline, or itemized deductions, negotiate them into the lease rather than assuming the law provides them.

What happens to my deposit or LOC if the landlord sells the building?

Your lease should require the landlord to transfer the deposit (or assign the LOC) to the buyer and to confirm the transfer to you in writing — otherwise you risk a new owner claiming it never received your security. This is one of the facts an estoppel certificate asks you to confirm, so keep your own records of what you posted and when (see estoppel certificates).
