Missouri Security Deposit Laws 2026

Example:

  • Monthly Rent: $1,200
  • Maximum Deposit: $2,400

Charging more than this limit can expose landlords to legal penalties.

When Must Landlords Return the Deposit?

Missouri law requires landlords to return the tenant’s security deposit within 30 days after the lease ends and the tenant moves out.

Key Requirements:

  • Must return deposit (or remaining balance) within 30 days
  • Must include an itemized list of deductions if any money is withheld

Missing this deadline can result in serious penalties.

What Can Landlords Deduct From a Security Deposit?

Landlords in Missouri can legally deduct for:

  • Unpaid rent
  • Damage beyond normal wear and tear
  • Excessive cleaning required to restore the unit

Examples of valid deductions:

  • Large holes in walls
  • Broken fixtures
  • Pet damage
  • Filthy conditions beyond normal use

Normal Wear and Tear vs Damage

Understanding this difference is critical—and one of the biggest mistakes landlords make.

✅ Normal Wear and Tear (NOT deductible):

  • Minor scuffs on walls
  • Faded paint
  • Worn carpet from regular use

❌ Damage (Deductible):

  • Large stains or burns in carpet
  • Broken doors or windows
  • Unauthorized alterations

Misclassifying this is a common reason landlords get sued.

What Landlords CANNOT Deduct

Missouri landlords cannot deduct for:

  • Routine repainting
  • Carpet replacement due to age
  • Minor nail holes or everyday use
  • Standard cleaning between tenants

If challenged, these deductions often fail in court.

Penalties for Violating Missouri Security Deposit Laws

If a landlord wrongfully withholds a deposit or fails to follow the law, tenants may recover:

  • Up to 2× the amount wrongfully withheld
  • Court costs and legal fees

A simple mistake could cost thousands of dollars.

Step-by-Step: How to Handle Security Deposits Properly

To stay compliant and protect yourself:

  1. Collect the correct amount (max 2 months’ rent)
  2. Document property condition at move-in (photos + checklist)
  3. Conduct a move-out inspection
  4. Prepare a detailed, itemized deduction list
  5. Return deposit within 30 days

Consistency and documentation are key.

Why Many Missouri Landlords Get This Wrong
