Grounded in the reception of common law dating back to 1820, and unlike the residential sector, Missouri places no statutory limits on commercial security deposits. The amount, holding requirements, and return timeline are governed entirely by the lease agreement, making careful lease drafting essential for both landlords and tenants.
Official Law Citation: The residential security deposit limitations in Mo. Rev. Stat. § 535.300 do not apply to commercial tenancies. Commercial deposits are governed by the lease document.
No Statutory Cap on Commercial Deposits
Missouri's residential two-month deposit limit (Mo. Rev. Stat. § 535.300) does not apply to commercial leases. In practice, this means:
Typical Commercial Deposit Amounts
Common deposit structures in Missouri commercial leases include:
- Retail: 1-3 months' base rent (sometimes including estimated CAM charges)
- Office: 2-6 months' base rent for new businesses; 1-2 months for established companies
- Industrial/Warehouse: 1-3 months' gross rent
- Startups or High-Risk Tenants: 6-12 months' rent, or a combination of cash deposit and personal guarantee
Alternatives to Cash Deposits
Many commercial tenants and landlords in Missouri prefer alternatives to large cash deposits:
Letters of Credit (LOC)
- Issued by a bank in favor of the landlord
- Landlord can draw on the LOC if the tenant defaults
- Preserves the tenant's working capital
- Should be irrevocable and unconditional
- Must have an expiration date extending beyond the lease term (or include "evergreen" auto-renewal clauses)
Bank Guarantees
- Similar to an LOC but structured as a guarantee from the tenant's bank
- Less common in the U.S. than in international commercial deals
- Often used for foreign-based tenants leasing in Missouri
Personal Guarantees
- Officers, directors, or owners of the tenant entity personally guarantee lease obligations
- Often used in addition to a cash deposit or LOC, especially for single-member LLCs or newly formed entities
- Can be "good guy" guarantees (limited to obligations up to the point the tenant surrenders possession)
Holding and Managing the Deposit
Because Missouri law does not dictate how commercial deposits must be held:
- Commingling: Landlords may generally commingle commercial security deposits with their operating funds unless the lease states otherwise. However, if a licensed real estate broker manages the property, they must maintain separate trust accounts for each tenant's deposit unless a written agreement permits otherwise.
- Interest: Landlords are not required to pay interest on commercial deposits. If the lease is silent, no interest is owed.
- Accounting: There is no statutory requirement to provide itemized deductions. However, best practice (and most leases) require the landlord to provide a written accounting of any deductions.
Allowable Deductions
Common deductions from commercial security deposits include:
- Unpaid Rent and CAM Charges: Any base rent, percentage rent, or common area maintenance charges in arrears.
- Property Damage: Costs to repair damage beyond normal wear and tear.
- Holdover Damages: If the tenant remains past the lease expiration without permission, the landlord may deduct holdover rent (often at 150-200% of the base rate, per the lease).
- Restoration/Make-Good Costs: Costs to return the premises to the condition required by the lease (e.g., removing tenant improvements, repainting, replacing flooring).
- Unpaid Utilities: If utilities are billed to the tenant under the lease.
- Legal Fees: If the lease includes a clause allowing the landlord to recover attorneys' fees from the deposit.
Deposit "Burn-Down" Provisions
Sophisticated commercial leases often include a "burn-down" provision, which reduces the security deposit amount over time if the tenant remains in good standing:
- Example: A 6-month deposit might reduce to 3 months after year 3, and to 1 month after year 5.
- Condition: The burn-down is typically contingent on no defaults during the lease term.
Best Practices for Commercial Landlords
- Negotiate Aggressively for Startups: New businesses have the highest default risk. Require a larger deposit, LOC, or personal guarantee.
- Include a Detailed Deduction Clause: Even though not legally required, itemize what can be deducted to prevent disputes.
- Set a Clear Return Timeline: Specify exactly how many days after lease expiration (e.g., 30, 60, or 90 days) you have to return the balance.
- Track LOC Expiration Dates: If using a letter of credit, set calendar reminders 90 days before expiration to ensure the tenant renews it. If they don't, draw on it immediately.
- Require Deposits Cover "Make-Good": Ensure the deposit amount is sufficient to cover the estimated cost of restoring the space.

Frequently Asked Questions
▶What are the Missouri landlord-tenant laws every property owner should know?
Missouri is generally considered a landlord-friendly state, featuring straightforward eviction processes, no rent control, and a relatively high security deposit limit. Recent legislation in 2024 has further solidified this stance by prohibiting local governments from enacting rent control or eviction moratoriums. This guide covers the essential compliance requirements for property owners and landlords.
Read the complete guide▶What is the Missouri eviction process and how long does it take?
The Missouri eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Missouri. The full court process varies but typically takes several weeks.
Read the complete guide▶What are the Missouri security deposit rules and return deadlines?
Missouri has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Missouri rent increase laws and caps for landlords?
Missouri has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether Missouri has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Missouri?
Missouri has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee. Late fee provisions must be stated in the lease agreement, and fees must be reasonable. Check Missouri state law and any applicable local ordinances for the exact grace period and late fee limits that apply to your rental property.
Read the complete guide▶What disclosures must Missouri landlords provide to tenants?
Missouri landlords must provide certain disclosures to tenants before or at the time of lease signing. Common required disclosures include lead-based paint hazards (for pre-1978 buildings, a federal requirement), the identity of the landlord or property manager, and any known material defects in the property. Additional state-specific disclosures may include flood risk, mold hazards, and environmental conditions.
Read the complete guide▶What are the Missouri lease requirements for rental properties?
Missouri recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting. Certain lease clauses that waive tenant statutory rights may be void and unenforceable under Missouri law.
Read the complete guide▶What are Missouri landlord maintenance obligations and habitability standards?
Missouri landlords must maintain rental properties in a condition that is fit for habitation and complies with applicable building, housing, and health codes. This includes maintaining structural integrity, plumbing, heating and cooling systems, electrical systems, and pest control.
