Montana Security Deposit Limits and Deadlines

A breakdown of Montana landlord-tenant laws on security deposits.

Most residential leases and rental agreements in Montana require a security deposit. This is a dollar amount, usually one month's rent, that's intended to cover damage to the premises beyond normal wear and tear, and to cushion the financial blow if a tenant skips out early on the lease without paying. Here’s a summary of Montana landlord-tenant laws that cover the use and return of security deposits.

Does Montana law limit how much a landlord can charge a tenant for a security deposit?

No. In Montana, there's no statutory limit on security deposits at the state level, but check your city and county laws to see if your municipality has set a cap on security deposits for residential rentals.
