    Montana Security Deposit Law

(MCA § 70-25-202(1)(a), (b))

    Itemized statement of deductions

    Landlords must give the departing tenant a written list of rent due and damage and cleaning charges within 30 days, or they forfeit the right to withhold for damage or cleaning (MCA §§ 70-25-202, 70-25-203). (MCA § 70-25-202(1)(a), MCA § 70-25-203)

    More Montana deposit rules

    Where the deposit is held

    Montana's security deposit law does not require landlords to keep deposits in a separate, trust or interest-bearing account (MCA Title 70, ch. 25). (MCA Title 70, ch. 25 (no holding rule))

    Receipt or written notice of the deposit

    Montana does not require a receipt for a security deposit or a notice saying where it is held (MCA Title 70, ch. 25). (MCA Title 70, ch. 25 (no receipt rule))

    Move-in condition checklist

    A Montana landlord that requires a security deposit must give each tenant, when the lease is signed or the tenancy begins, a separate signed written statement of the unit's present condition (MCA § 70-25-206(1)-(2)). (MCA § 70-25-206, MCA § 70-25-201(2))

    A landlord that skips the statement (or, on written request, the prior tenant's damage and cleaning list) cannot recover damage or cleaning costs unless it proves by clear and convincing evidence that this tenant caused the damage (§ 70-25-206(3)). Either party may ask for an inspection within 1 week before the tenancy ends (§ 70-25-201(2)).

    Pet deposits

    Montana has no pet-deposit statute, though any charge for cleaning and damages, however labeled, is presumed to be a refundable security deposit, and the 2023 emotional-support-animal law does not address deposits (MCA §§ 70-25-101(4), 70-24-114). (MCA § 70-25-101(4), MCA § 70-24-114)

    Nonrefundable fees

    Montana presumes that any fee or charge for cleaning and damages is a security deposit no matter what the lease calls it, so a 'nonrefundable' cleaning or damage fee is treated as refundable deposit money (MCA § 70-25-101(4)). (MCA § 70-25-101(4), MCA § 70-24-201(4))

    Any deposit the lease requires the tenant to keep in place for part or all of the term is also presumed to be a security deposit. Since 2025 a landlord also may not add a fee based on how rent is paid, except to recoup an electronic bank fee (§ 70-24-201(4)).

    Small-landlord exemptions

    Montana's deposit rules apply to every rental of a dwelling covered by the landlord-tenant acts, with no carve-out for small or owner-occupant landlords (MCA §§ 70-25-102, 70-24-104). (MCA § 70-25-102, MCA § 70-24-104)

    Deposit alternatives and installments

    No Montana statute regulates deposit-alternative products, surety bonds or installment payment of deposits (MCA Title 70, ch. 25). (MCA Title 70, ch. 25)
