Rent Increases in Montana: What Are My Rights?
Montana law is thin on rent increases. This page covers what the lease sets, local rent control, and the ban on raising rent as payback for a complaint. It does not cover being told to leave.
-
A Montana city or county with self-government powers cannot control the amount of rent charged for private residential (housing) or commercial (business) property. Property the local government has an interest in does not count as private residential property. That includes an interest through a housing authority.

A Montana landlord and tenant may put the rent and the term (length) of the agreement in a rental agreement. They may add other terms that the law does not prohibit. Read what your lease says about rent.

Unless your Montana rental agreement provides otherwise, you pay as rent the rental value for using the home. The landlord decides that value.

Unless your Montana rental agreement provides otherwise, a roomer who pays weekly rent rents week to week. In all other cases the rental is month to month.

In Montana, a landlord or tenant can end a month-to-month rental with at least 30 days' notice in writing. The notice must name the date the rental ends.

Unless the law says otherwise, a Montana landlord may not retaliate (punish you) by raising rent. That holds after you tell a government agency about a problem. The agency must be in charge of a building or housing code. The problem must materially affect health and safety. An inspector can condemn a very bad home and make everyone leave.

Unless the law says otherwise, a Montana landlord may not retaliate (punish you) by raising rent. This applies after you complain in writing to the landlord of a violation of the landlord's duties. Those duties include making repairs to keep the home fit to live in.

Unless the law says otherwise, a Montana landlord may not retaliate (punish you) by raising rent. That applies after you organize or join a tenant's union or similar organization.

In a Montana court case, a complaint you made within 6 months before the alleged retaliation (punishment) is evidence of it. The court must find retaliation unless evidence shows the landlord did not. This rule does not apply if you made the complaint after notice of a proposed rent increase or a cut in services.

If a Montana landlord retaliates (punishes you) in the ways the law bans, you have a defense. The defense applies in any action for possession (to take back the home) that is a form of retaliation.

Suppose your landlord punishes you for a complaint or for joining a tenant group. You then have the same options as for a lockout (your landlord keeps you out) or a cut in services. You may recover possession (get the home back) or end the rental agreement. In either case you may recover an amount not more than 3 months' periodic rent or treble (3 times) your loss, whichever is greater. With $900 rent, 3 months' rent is $2,700. If a court later disagrees, you can owe the rent and face eviction. Get legal help first. You get this money only if you win your case and your landlord pays.

A Montana landlord can still bring an action for possession (to take back the home) in three cases. One is a code violation caused mainly by lack of reasonable care by you, your family, or others there with your consent. Another is if you are in default in rent. The third is code work that would effectively take away your use of the home.

If you complain to your landlord about a problem, put it in writing. Keep a copy and note the date you gave it.
