Montana security deposit

Montana Residential Landlord and Tenant Act is where Montana sets whether there is a deposit cap, what may be deducted, and how long a landlord has to return what is left. Document the unit at move-in and move-out, return keys the way the lease requires, and keep a forwarding address. We do not reprint a number that can go stale.

  • Keep move-in and move-out photos, dated, of every room and the condition of walls, floors, appliances, and keys.

  • Give a forwarding address in writing.
  • List each disputed deduction in one sentence with the reason.

What usually has to be proven?

A deposit dispute in Montana is a records problem first. What was paid, what was deducted, what the unit looked like at both ends, and whether keys were returned as the lease required. Montana Residential Landlord and Tenant Act is the chapter to open for caps, timing, and itemization — not a national chart.

Should I send a demand letter?

A calm, dated letter that lists each deduction and a way to reach you is something any renter can write. Send it in a way you can prove. Small-claims court exists in Montana; whether it is worth filing, and what the court can order, is a question for legal aid or the court's own self-help materials.

Does Montana use the URLTA?

Montana has a Residential Landlord and Tenant Act (Mont. Code Title 70, chapter 24). Justice court hears many cases. A Colorado ordinance does not apply. We name the chapter. We do not reprint a number.

The Montana chapter

Montana Residential Landlord and Tenant Act (Mont. Code §§ 70-24-101 to 70-26-114) is the starting point. We name it. We do not paraphrase a day-count or a dollar cap out of it.

Montana state law is the floor. Cities may add rent boards, just-cause rules, or extra protected classes. Confirm locally.

Ordinary wear and damage are different ideas in most states. What counts as each is a Montana and facts question. Photos from move-in and move-out are what make that argument possible.
