What Is a Security Deposit in a Commercial Lease?
Last reviewed: October 2026 · Jurisdiction: United States (examples: New York, Texas)
A commercial lease security deposit is cash or credit support, such as a letter of credit, that the landlord holds against unpaid rent, damage beyond normal wear and tear and other tenant defaults. The lease, not a statute, sets most terms: amount, form, burn-down and return deadline. Some state laws, such as New York's and Texas's, still apply.
| Key facts (United States, as of October 2026) | Rule | Source |
|---|---|---|
| What governs a commercial deposit | Mainly the lease; most residential deposit statutes don't apply to commercial space | Lease terms; see the state examples below |
| New York: deposits on any rental of real property | Landlord holds the money in trust and may not commingle it with its own funds | N.Y. Gen. Oblig. Law § 7-103 |
| Texas: commercial security deposits | Refund on or before the 60th day after surrender, with a written itemized list of any deductions; the duty runs once the tenant gives a written forwarding address | Tex. Prop. Code ch. 93, subch. B (§§ 93.005–93.011) |
| If the tenant goes bankrupt | The landlord's claim for future rent is capped; courts generally weigh the deposit against that cap | 11 U.S.C. § 502(b)(6) |
| Tax treatment for the landlord | A deposit the landlord must repay generally isn't income when received | *Commissioner v. Indianapolis Power & Light Co.*, 493 U.S. 203 (1990) |
The amount is negotiated and often stated as a number of months of base rent. It depends on the tenant's creditworthiness, the lease term, the landlord's build-out costs and the market. Credit tenants (large companies with strong credit ratings) may post little or nothing; startups and financially weaker tenants are usually asked for more.
Cash deposit vs. letter of credit vs. guaranty
| Form | Who it often suits | How the landlord uses it | If the building is sold or the landlord fails |
|---|---|---|---|
| Cash deposit | Smaller tenants and shorter leases | Applies the cash to unpaid rent or damages as the lease allows | The lease should require transfer to the new owner. If the cash is commingled, a tenant may be left as an unsecured creditor in a landlord bankruptcy |
| Letter of credit | Larger tenants and longer terms | Draws on the bank by presenting the documents the letter requires | Needs to be transferable or reissued to the new owner; the bank's obligation is separate from the landlord's finances |
| Personal or corporate guaranty | Closely held businesses, often alongside a smaller cash deposit | Has no fund to draw; the landlord must pursue the guarantor | Usually runs with the lease to the new owner if the lease and guaranty allow assignment |
What to negotiate before you sign
- Amount and form. Ask whether a letter of credit or a limited guaranty can replace part of the cash.
- Burn-down. A schedule that reduces the deposit after a run of on-time payments.
- How it is held. Whether the deposit is kept in a separate account and whether it earns interest, and for whom.
- Return timeline. A fixed number of days after the lease ends for the refund or an itemized accounting.
- Sale of the building. A requirement that the deposit transfers to any new owner, and that the old landlord stays responsible until it does.
- Notice before deductions. Written notice and a chance to cure before the landlord draws on the deposit.
Getting your deposit back
- Read the surrender clause well before move-out: restoration duties, removal of fixtures and cabling, and cleaning standards.
- Do a walkthrough with the landlord or property manager and document the space with dated photos and video.
- Return keys and access cards in writing and give a forwarding address for the refund.
- Ask for an itemized accounting of any deductions within the lease's deadline.
- Send a written demand if the refund or accounting doesn't arrive, citing the lease section.
- Involve counsel if the amount is significant or the landlord treats the deposit as a penalty.
State and federal rules that still reach commercial deposits
Most protections in a commercial lease are the ones you negotiate, but a few laws apply anyway:
- New York treats a deposit on any rental of real property as the tenant's money held in trust, and the landlord can't commingle it with its own funds (General Obligations Law § 7-103).
- Texas has a separate commercial-deposit chapter: the landlord must refund the deposit, or account for deductions in writing, on or before the 60th day after you surrender the space, once you've given a forwarding address (Property Code §§ 93.005–93.011).
- Federal bankruptcy law caps what a landlord can claim for future rent when a tenant's lease is rejected in bankruptcy (11 U.S.C. § 502(b)(6)). That cap shapes how much security a landlord asks for from a riskier tenant.
Other states have their own rules, or none. Ask a business or real estate attorney where the property is located before relying on any of them.

Frequently Asked Questions
Is a commercial security deposit regulated by state law?
Much less than a residential deposit. The lease usually controls return timing, permitted deductions and disputes. Some states still have rules that reach commercial space: New York requires deposits to be held in trust and not commingled (Gen. Oblig. Law § 7-103), and Texas sets a 60-day refund rule for commercial deposits (Prop. Code § 93.005). Check with counsel where the property is located.
What alternatives to cash deposits are available?
Letters of credit (bank-issued instruments guaranteeing payment) are common in commercial leases, particularly for larger tenants. Personal or corporate guaranties from the principals are another alternative to, or supplement for, cash deposits.
What is a "burn down" deposit?
A deposit that decreases over time as the tenant demonstrates reliable payment. For example, a lease might reduce the deposit after a set period of on-time payments. Negotiating a burn-down helps tenants recover capital over time.
When does the landlord have to return the security deposit?
The lease controls. Many commercial leases set a window after the lease ends for the landlord to return the deposit or provide an itemized accounting of deductions. Residential statutes in many states set fixed deadlines, but those usually don't apply to commercial space, so negotiate a clear deadline in the lease.
What can a commercial landlord deduct from a security deposit?
Unpaid rent, repair costs for damage beyond normal wear and tear, cleaning costs, and any other amounts owed by the tenant under the lease. The lease should specify what deductions are permitted.
Can a landlord keep the whole deposit if I break the lease early?
Not automatically. A security deposit is generally security for the landlord's actual losses under the lease, such as unpaid rent and re-letting costs, rather than a fixed penalty. What the landlord can keep depends on the lease language and state law, including whether the landlord must try to re-let the space. Have counsel review the lease before you negotiate an early exit.
Is a commercial deposit taxable to the landlord?
Generally not when received, if the landlord has to return it. The Supreme Court held that deposits subject to a repayment obligation aren't income on receipt (Commissioner v. Indianapolis Power & Light, 1990). A deposit becomes income when the landlord applies it to rent or keeps it, and a "deposit" that is really prepaid rent is usually income right away. Landlords should confirm with a tax advisor.
What happens to my deposit if my company files for bankruptcy?
The landlord can usually apply the deposit to what it's owed, but federal law caps the landlord's claim for future rent when a lease is rejected (11 U.S.C. § 502(b)(6)), and courts generally count the deposit against that cap. The details depend on the lease and the case, so talk to bankruptcy counsel early.
