What landlords ask about this in Montana.

How much notice do I need to give for a rent increase?
Montana requires 30 days of written notice before a rent increase takes effect. Count from the day the tenant receives it, not the day you wrote it. Cities with rent control often require more, so check the local ordinance if the property sits in one.
Can I raise rent during a lease term?
Not unless the lease itself contains a clause allowing it. A fixed-term lease locks the rent for the term. If the tenant is month-to-month, you can raise it with 30 days of notice in MT.
What percentage can I raise rent?
Montana sets no statewide cap and has no local rent control. Beyond any cap, the practical limit is what the market bears. Be aware that a large increase timed right after a complaint or repair request can be read as retaliation, which is separately illegal.
Do I need to explain why I’m raising rent?
No. Montana does not require a reason for a rent increase on a month-to-month tenancy. A short explanation often reduces argument, but the notice is valid without one.

This is general information about Montana landlord-tenant law, not legal advice. Local ordinances can be stricter than the state rule, and if a dispute is already underway it is worth an hour of a lawyer’s time.
