Montana Residential Security Deposit Laws

Official Law Citation: Security deposit rules, including timelines and allowable deductions, are outlined in the Residential Tenants Security Deposits Act (MCA Title 70, Chapter 25).

Montana's Residential Tenants' Security Deposits Act (MCA Title 70, Chapter 25) heavily regulates the handling, deduction, and return of residential security deposits.

While the state is lenient regarding the amount a landlord can collect upfront, it is intensely strict regarding the paperwork required to legally keep it.

Deposit Limits and Holdings

  • Maximum Amount: Montana law does not cap the maximum amount a landlord can charge for a security deposit. Standard practice is usually one to two months' rent, but higher amounts are legally permissible if agreed upon.
  • Account Requirements: Landlords are not required to hold the security deposit in a separate, interest-bearing trust account, nor are they required to pay the tenant accrued interest, unless explicitly agreed to in the lease.

The Mandatory Move-In Condition Report

The most critical element of Montana deposit law is the Condition of the Premises Statement.

If a landlord collects a security deposit, they must provide the tenant with a separate written statement of the present condition of the premises prior to the tenant taking possession.

  • The Penalty for No Checklist: If the landlord fails to provide this written move-in report, they are legally barred from retaining any portion of the security deposit for damages when the tenant moves out (unless the landlord has clear-cut, indisputable proof the tenant caused the damage, which is incredibly hard to prove without a baseline report).

Cleaning vs. Damage: The Move-Out Rules

Montana law uniquely addresses regular cleaning versus damage.

  1. Cleaning Notice: A landlord cannot automatically deduct money for standard cleaning. By law, the landlord must give the tenant written notice of any cleaning deficiencies and grant the tenant 24 hours to return to the property and fix the cleaning issues themselves before the landlord can hire a cleaner and deduct the cost from the deposit.
  2. Normal Wear and Tear: As in all states, landlords cannot deduct funds for standard "normal wear and tear" (e.g., foot traffic on carpets, minor sun fading on curtains). Deductions are reserved for negligent damage (e.g., large holes in drywall, broken windows, ruined appliances).

Deposit Return Deadlines

The primary statutory deadline for returning a security deposit in Montana is 30 days.

Under MCA 70-25-202, the landlord must provide the departing tenant with a written, itemized list of any deductions (for damage, cleaning, or unpaid rent) and return the remaining balance of the security deposit within 30 days of the termination of the tenancy or the tenant's surrender of the premises, whichever occurs first.

The 10-Day Exception

There is a specific exception that accelerates the return timeline. The landlord must return the full security deposit within 10 days only if all of the following conditions are met:

  • There are no damages to the premises.
  • There is no cleaning required.
  • There is no unpaid rent.
  • The tenant can demonstrate that no utilities are unpaid by the tenant.

If a landlord fails to meet these statutory deadlines, they forfeit the right to withhold any money whatsoever, and the tenant can sue them in court for double the amount of the improperly withheld deposit, plus attorney fees.
