Pass-Through Costs and Rent Increases in Montana

Understanding why and how your rent may increase can help you budget, avoid surprises, and know your rights as a renter in Montana. While Montana does not have statewide rent control or rent stabilization, landlords still must comply with state laws when raising rent—including situations involving pass-through costs (like property tax hikes or upgrades).

What Are Pass-Through Costs?

Pass-through costs refer to expenses that landlords sometimes try to shift onto tenants. Common examples include:

  • Increases in property taxes
  • Certain utility upgrades
  • Major repairs or renovations

In jurisdictions with rent control, these costs may be limited or require approval. In Montana, landlords generally have more flexibility, but there are still legal limits they must observe.

Laws About Rent Increases in Montana

Montana does not have a rent control law. However, landlords must follow the Montana Residential Landlord and Tenant Act when increasing rent.[1]

  • Written Notice: Landlords must provide at least 30 days' written notice before any rent increase for month-to-month tenants.
  • For leases with a fixed end date, rent cannot increase during the lease unless the lease specifically allows it.
  • There is no cap on how much rent can be increased.

This means if your landlord faces higher costs (like property taxes or improvements), they could raise your rent at lease renewal or with adequate notice. However, they cannot raise the rent in a discriminatory or retaliatory manner.

Are There Official Forms for Rent Increases?

Montana does not require a specific form for rent increase notices, but the notice must be in writing. The notice should include:

  • The new rent amount
  • The date the increase takes effect (at least 30 days after the notice)
  • The address of the rental unit

Example: Your landlord gives you a letter stating, “Effective June 1, your rent will increase from $900 to $950 per month.” This fulfills the legal requirement as long as you receive it at least 30 days in advance.

If your landlord wants to provide you with a formal notice, the Montana Judicial Branch offers the Landlord and Tenant Forms. Look for the "Notice of Change of Terms" form, which can be used to document a rent increase for month-to-month leases.

What Should Tenants Do If They Receive a Rent Increase?

Always review the notice for accuracy and proper timing. If you believe the increase is retaliatory or not properly noticed, you may have grounds to dispute it. Retaliatory rent increases (for example, after you ask for repairs) are prohibited under Montana law.

If you feel the increase is unfair, talk to your landlord first. Clear communication sometimes resolves misunderstandings.
  • Document every conversation and keep copies of all notices.
  • Contact the local tenant-landlord authority if you suspect illegal practices.

Who Handles Rental Disputes in Montana?

Rental disputes in Montana are typically handled by the Montana Justice Courts. If you feel your rights are violated (for example, by an improper rent increase), you may file a complaint there. The courts enforce the Montana Residential Landlord and Tenant Act.

Overall, while Montana landlords have broad authority to adjust rents, they must still follow notice requirements. Renters can use written communication, available government forms, and contact state courts if concerns arise.
