Montana State Laws Prohibiting Landlord Retaliation

Learn what types of landlord retaliation are illegal in Montana.

Montana state law (Mont. Code Ann. § 70-24-431) prohibits landlords from retaliating against tenants.

Tenant Rights Protected Against Landlord Retaliation in Montana

It is illegal for a landlord to retaliate against a tenant in Montana who has exercised a legal right, including:

  • complaining to the landlord about unsafe or illegal living conditions
  • complaining to a government agency, such as a building or health inspector, about unsafe or illegal living conditions, or
  • assembling and presenting your views collectively—for example, by joining or organizing a tenant union.

Types of Retaliation That Are Against State Law

The kinds of retaliatory acts covered by Montana law include terminating a tenancy or filing an eviction lawsuit; increasing the rent; or decreasing services, such as locking the laundry room. Montana state law presumes retaliation if the landlord acts in these types of negative ways within six months of the date that a tenant has exercised a legal right, such as complaining to the landlord about an unsafe heater in the apartment.

For advice on how to respond to—and prove—retaliation, see the article Landlord Retaliation.
