Montana Move-In/Move-Out Checklist Rules Every Landlord Must Follow in 2026

The Montana Statute Behind the Move-In Checklist

Montana's residential landlord-tenant relationships are governed primarily by the Montana Residential Landlord and Tenant Act of 1977, codified in Montana Code Annotated (MCA) Title 70, Chapters 24 and 25. The security deposit rules — including the checklist requirement — live specifically in MCA §§ 70-25-101 through 70-25-206.

Under MCA § 70-25-206, any person engaged in the rental of property for residential purposes who requires a security deposit shall furnish to each tenant, in conjunction with execution of a lease or creation of a tenancy, a separate written statement as to the present condition of the premises intended to be let. The checklist isn't optional courtesy — it's a legal precondition for enforcing your deposit deductions.

At the written request of the tenant, a copy of the written list of damage and cleaning charges, if any, provided to the tenant of the immediately preceding leasehold agreement for the premises in question must be provided to the tenant. In plain English: if an incoming tenant asks in writing what you charged the last tenant, you have to show them. Keep your prior move-out statements organized.

What the Written Statement Must Contain

Each written statement of the present condition of a premises intended to be let shall contain at least: (a) a clear and concise statement of the present condition of the premises known to the landlord or the landlord's agent or which should have been known upon reasonable inspection; (b) if the premises have never previously been let, a statement indicating that fact; and (c) the signature of the landlord or the landlord's agent.

The statute sets a floor, not a ceiling. Most prudent landlords go further — room-by-room condition notes, photos, appliance serial numbers, and a tenant sign-off line — but those three elements are the legal minimum. A checklist without the landlord's signature is technically deficient under Montana law, a detail that trips up even experienced self-managers.

Montana law also prohibits landlords from charging any nonrefundable fees to tenants. Any fees for cleaning or damages are considered part of the security deposit under MCA § 70-25-101(4). That means the condition statement matters even more: it's the baseline against which all cleaning charges are eventually measured.

Scenario Walkthrough: From Move-In to Deposit Return

Note: The following is a labeled hypothetical scenario to illustrate how the statute applies in practice. It does not represent any actual landlord, tenant, or property.

The Setup. Sarah owns a two-bedroom rental in Missoula. She collects a $1,800 security deposit from new tenant Marcus on September 1, 2026. Marcus signs a 12-month lease.

Step 1 — Move-In (September 1). Sarah completes a written condition statement per MCA § 70-25-206. She documents the condition of every room, notes a small scuff on the hallway wall as a pre-existing defect, signs the document, and gives Marcus a copy at lease signing. Marcus is entitled to inspect the unit to verify the statement's accuracy. Sarah also keeps the prior tenant's damage/cleaning list in a folder in case Marcus ever asks for it in writing.

Step 2 — Pre-Move-Out Inspection (August 2027, within one week of termination). The premises may be inspected within one week before termination of the tenancy at the request of either party under MCA § 70-25-201(2). Sarah walks through with Marcus, notes a broken towel bar and stained carpet in the bedroom, and documents everything in writing. This walkthrough is not required by statute but gives both parties a chance to resolve disputes before move-out.

Step 3 — Marcus Moves Out (September 1, 2027). He hands over the keys and provides his forwarding address. The deposit clock starts the moment Sarah accepts surrender of the unit — not the lease end date.

Step 4A — No Deductions. If Sarah finds no damages, no unpaid rent, and no cleaning needed: she must return the security deposit within 10 days.

Step 4B — Deductions Apply. Sarah documents the broken towel bar ($75) and carpet cleaning beyond normal wear ($200). Within 30 days subsequent to the termination of a tenancy or surrender and acceptance of the leasehold premises, whichever occurs first, she must provide Marcus with a written list of any rent due and any damage and cleaning charges the landlord alleges are the tenant's responsibility. Delivery of the list must be accompanied by payment of the difference between the security deposit and the permitted charges.

Step 5 — The Cleaning Charge Wrinkle. Landlords cannot deduct cleaning charges from the security deposit unless written notice is given to the tenant outlining what cleaning was not done by the tenant and providing a 24-hour window for the tenant to complete the required cleaning, as specified in MCA § 70-25-201(3). If a tenant vacates without notice, this requirement is waived. Sarah gave Marcus proper notice of his move-out date, so she must follow this cleaning-notice step before she can deduct for cleaning.

The Penalty for Getting It Wrong: A Quick-Reference Table

Common Mistakes Montana Landlords Make With Checklist Compliance

Mistake 1: Skipping the checklist for month-to-month tenants. The statute applies to "the execution of a lease or creation of a tenancy" — not just fixed-term leases. If you collect a deposit for a month-to-month rental, the move-in statement requirement applies just the same.

Mistake 2: Attaching the checklist to the lease instead of making it a separate document. The statute explicitly requires a separate written statement as to the present condition of the premises. Burying condition notes in a lease addendum may not satisfy the "separate" requirement and could be challenged in a dispute.

Mistake 3: Forgetting the landlord or agent signature. The written statement must include, at minimum, a concise description of the present condition of the premises, a statement that the property has not previously been leased if such is true, and the landlord's or agent's signature. An unsigned checklist is legally incomplete.

Mistake 4: Confusing the 10-day and 30-day deadlines. The deposit returns in 10 or 30 days under MCA § 70-25-202 — 10 days with no deductions, 30 days with an itemized list of damage and cleaning charges. Missing the 10-day window when there are genuinely no charges is a common and unnecessary misstep. Bad faith is typically presumed if the landlord fails to return the deposit or provide a written description of damages and charges within the statutory deadline.

Mistake 5: Treating "last month's rent" as a free-floating fee. In Montana, a security deposit is defined as any advance or deposit of money furnished by a tenant to a landlord to secure the performance of the terms of the rental agreement, including any required prepayment of rent other than the first month's rent. However, an advance payment of the first month's rent is not considered a security deposit unless it exceeds the amount of rent. Pre-collected "last month's rent" is almost always a security deposit under Montana law — subject to all the same checklist and return deadlines.

What Montana Does Not Require (And What You Still Should Do)

Montana sets no statutory cap on how much a landlord can collect for a security deposit. Montana does not require landlords to use a specific account or follow dedicated procedures when holding security deposits, and the law does not require landlords to notify tenants where the deposit is being held. Montana also does not require landlords to keep security deposits in interest-bearing accounts, and property owners do not need to pay tenants interest on the funds held during the rental term.

That flexibility doesn't mean you should be sloppy. Even without a deposit cap, a deposit that seems disproportionate can raise fair housing concerns if applied inconsistently across applicants. Keep your deposit amounts uniform for comparable unit types and document your reasoning.

The statute is silent on photographs — it doesn't require them. But photos are your best evidentiary tool if a deduction is ever disputed in justice court. A signed checklist plus timestamped photos at move-in and move-out is a defensible record that makes the 30-day itemization process straightforward rather than contentious.
