Letter of Credit vs. Security Deposit in Commercial Leases: Which Is Better?

What Is a Security Deposit in a Commercial Lease?

A cash security deposit is money you pay to the landlord at signing that they hold throughout the lease term. If you default, the landlord can use the funds to cover unpaid rent, damages, or other obligations. If you perform all obligations, the deposit is returned (typically within 30–60 days of lease expiration).

Commercial security deposits are typically 1 to 6 months of base rent, though institutional landlords in major markets sometimes require more for startup tenants or tenants in financially sensitive industries. Unlike residential deposits, there is generally no statutory cap on commercial security deposits.

Pros and Cons of Cash Security Deposits

What Is a Standby Letter of Credit in a Commercial Lease?

A standby letter of credit (SBLC) is a guarantee issued by a bank on your behalf. The bank promises to pay the landlord up to the LC face amount if the landlord presents a compliant draw request (i.e., certifies that you've defaulted). You don't give the landlord any cash — instead, you give the landlord a right to call on the bank.

The bank, in turn, holds collateral from you — either a cash deposit equal to the LC amount (fully cash-collateralized) or a credit line secured by your business or personal assets.

How the LC Mechanism Works

1. Issuance: Your bank issues the LC naming the landlord as beneficiary. The LC specifies the face amount, expiration date, draw conditions, and presentation requirements.
2. Annual renewal: The LC is typically issued for one year and renews via an evergreen clause unless the bank gives notice of non-renewal.
3. Draw: If you default, the landlord presents draw documents to the bank. The bank pays within 1–3 business days — no court proceedings required. This is what makes LCs so attractive to landlords.
4. Reimbursement: After the bank pays the landlord, they debit your account or call your credit line. You owe the bank, not the landlord.

The Evergreen Clause Explained

The evergreen clause (also called an "automatic renewal" or "auto-extension" provision) means the LC renews automatically each year unless the issuing bank gives written notice of non-renewal within a specified window before the expiration date.

Standard evergreen non-renewal notice windows are 30 to 90 days before the LC expiration. If the bank fails to give this notice, the LC renews for another year without the tenant needing to do anything.

Why Evergreen Clauses Matter for Tenants

If your bank sends a non-renewal notice and you fail to either (a) replace the LC with another bank or (b) submit a renewal request in time, the LC will expire. Most commercial leases treat an expiring LC as an immediate default — triggering the landlord's right to draw before it expires.

The standard lease clause reads: "If Tenant fails to renew or replace the Letter of Credit at least [30] days prior to its expiration, Landlord may draw the full amount of the Letter of Credit without further notice to Tenant."

Negotiating Evergreen Clause Terms

As a tenant, you want:

• A longer non-renewal notice period from the bank (90 days rather than 30) so you have more time to react
• A longer cure period in the lease before the landlord can draw on a non-renewed LC (30 days rather than immediate)
• An obligation on the landlord to provide notice before drawing on a non-renewed LC

Draw Triggers: What Allows the Landlord to Draw

The draw triggers are the events that allow the landlord to present documents to the bank and receive payment. These should be clearly listed in the lease and should match the LC document's conditions.

As a tenant, push back on draw triggers that include non-monetary defaults or disputed charges. The issue is that LC draws are essentially automatic — once the landlord presents the right documents to the bank, the bank pays regardless of whether you believe the default is legitimate. Your only recourse is to sue the landlord after the fact.

Side-by-Side Comparison: LC vs. Security Deposit

When Is a Letter of Credit Better?

Choose (or negotiate for) a letter of credit when:

• The deposit amount is large (3+ months of rent on a significant space) and tying up that capital is material to your operations
• You're a startup or early-stage company and the landlord requires significant security — an LC lets you preserve cash for operations while still providing the landlord's required security level
• You have an existing credit facility that includes LC capacity at low cost, making the LC essentially free to issue
• The landlord is an institutional REIT or fund that specifically requires LCs rather than cash (common in Class A office and retail)

When Is a Cash Security Deposit Better?

Choose a cash security deposit when:

• The lease is smaller and the deposit amount is manageable without affecting operations
• You lack a banking relationship that would support LC issuance
• You have concerns about disputed defaults — cash deposits require the landlord to provide accounting; wrongful withholding can be challenged under state law
• The lease term is short (2–3 years) and the ongoing LC fee and administrative burden isn't worth the capital preservation
• You're in active lease negotiations where offering cash upfront signals financial strength

Negotiating Down the Security Amount

Whether you're offering an LC or cash, the initial security ask is almost always negotiable. Here are strategies that work:

1. Burndown Schedule

Propose a schedule where the required security decreases over time as you demonstrate payment history. Example: full security for years 1–2, 75% for years 3–4, 50% for years 5+. This is a win for both sides — landlord maintains security when risk is highest; tenant reduces carrying cost as the relationship matures.

2. Personal Guaranty Offset

Some landlords will reduce the security requirement if you provide a personal guaranty (or corporate parent guaranty) for some period. Offering a "good guy" clause (guaranty terminates upon proper surrender of the premises) is often acceptable to landlords and meaningfully reduces their risk concern.

3. Financial Statement Disclosure

Providing audited financials or strong bank references can allow a creditworthy tenant to argue for below-market security. For established companies, even a reference letter from your bank confirming your financial health can move the needle.

4. Offer Higher Rent in Exchange

Sometimes landlords are more concerned with yield than security. Offering a small bump in base rent (0.5–1%) in exchange for reducing the security deposit can be an efficient trade depending on your situation.

LC and Security Deposit Checklist

• Identify whether lease requires LC or cash security deposit — check if there's landlord discretion
• Calculate the opportunity cost of cash deposit vs. annual LC fee to determine which is cheaper
• Review LC draw triggers — push back on non-monetary default triggers
• Check evergreen clause — confirm non-renewal notice window and cure period before draw
• Calendar LC expiration 90 days out and set renewal reminder 45 days out
• Negotiate burndown schedule if possible — even a modest reduction in year 3+ is worth pursuing
• Check for consequential damage clauses — LC draw should not trigger additional liability
• Confirm return timeline for security deposit at lease end (30 days with itemized accounting is standard)
• Review whether LC face amount matches required security or if it can be reduced at burndown milestones
• Ensure replacement LC requirements are clear — bank name, form, delivery timeline
