Montana Security Deposit Law: A 2026 Landlord's Guide
How much can you charge in Montana?
No statutory cap. Cleaning charges require prior written notice and an opportunity to clean.
Returning the deposit: the 10–30 days deadline
After the tenancy ends, Montana gives you 10–30 days to return the deposit. 10 days if no deductions; 30 days otherwise. Blowing the deadline is the single most common way landlords lose deposit disputes — courts read these statutes strictly, and in many states a late or missing itemization forfeits your right to keep anything.
What you can deduct
- Unpaid rent and other amounts the lease authorizes
- Damage beyond normal wear and tear — holes in walls, broken fixtures, pet damage
- Never normal wear and tear — faded paint, carpet worn by ordinary use, minor scuffs
The dispute is almost never about the rule — it's about the evidence. Date-stamped move-in and move-out photos plus an itemized statement with receipts is what wins in small-claims court.
Interest and holding requirements
Montana has no general statewide requirement to pay interest on residential security deposits (local ordinances can differ — check your city). Some states in this position still regulate where deposits are held; see Mont. Code § 70-25-201 to -206 for any account or disclosure rules that apply to you.

How much can a landlord charge for a security deposit in Montana?
There is no statewide dollar cap — the lease sets the amount, though local ordinances may impose limits. See Mont. Code § 70-25-201 to -206.
How long does a Montana landlord have to return a security deposit?
10–30 days after the tenancy ends, generally with an itemized statement of any deductions. Missing the deadline can forfeit your right to deduct — and in many states triggers statutory damages.
What can a landlord deduct from a deposit in Montana?
Typically unpaid rent, damage beyond normal wear and tear, and other charges the lease authorizes. Normal wear and tear — faded paint, worn carpet from ordinary use — is never deductible. Documentation (move-in/move-out photos and an itemized list) is what wins disputes.
Handling Montana deposits with LandlordPro
LandlordPro keeps a ledger of every deposit you hold — who paid it, which lease it secures, and what happened to it. When a tenancy ends, the settlement workflow records what you returned and what you kept (with reasons), generates a tenant-facing settlement statement, and books any kept portion into your income reports correctly. Combined with the Montana eviction guide and move-in/move-out inspections with photos, you'll have the paper trail that deposit statutes reward.
