Idaho Rent Increase Laws: Mid-Lease Landlord Rules Explained

Facing a sudden rent increase can be alarming for Idaho renters. If your landlord wants to raise the rent in the middle of your lease, it’s important to know your rights under Idaho law. This guide explains when and how landlords can legally increase rent, the notice required, and your next steps if an unexpected increase happens.

When Can Idaho Landlords Legally Raise Rent?

Whether a landlord can raise your rent during a lease depends on what type of rental agreement you have:

• Fixed-Term Lease (e.g., 6- or 12-month lease): Landlords cannot raise rent until the lease expires, unless you both agree in writing to change the lease. Otherwise, the rent stays the same for the entire lease period.
• Month-to-Month Tenancy: A landlord can increase rent, but must provide a written 30-day notice before the new rent takes effect. There is no statewide rent control in Idaho.

This rule is governed by the Idaho Landlord and Tenant Act, specifically Idaho Code § 55-307, which requires at least 30 days' notice for changes to month-to-month tenancies.^[1]

How Rent Increases Work in Idaho

Idaho law does not limit how much rent can increase, but any change must follow proper notice and agreement terms. The specific steps are:

• Review your lease: Check if it’s fixed-term or month-to-month, and see if it allows for mid-lease changes.
• If you have a fixed lease: Landlords must wait until the lease ends, except if the lease itself states otherwise.
• If you get a rent increase notice: For month-to-month tenants, your landlord must give you at least 30 days' written notice. For most fixed leases, notice does not allow mid-lease increases.

If your landlord tries to increase rent before your lease ends, and your lease does not allow it, you can point to your signed lease and Idaho law to contest the increase.

Required Notice for Rent Increase

Idaho landlords must provide at least 30 days’ written notice before raising rent for month-to-month tenancies. The notice should clearly state:

• The new rent amount
• The date the increase starts
• It must be delivered in writing

For fixed leases, unless you sign an amendment or your lease allows adjustments during the term, the rent cannot be changed mid-lease.^[1]

Official Complaint and Forms for Idaho Renters

Idaho does not have a central housing tribunal for renters, but if your landlord issues an improper rent increase or violates your lease, you may:

• Write a letter (see sample forms below) to your landlord explaining your lease and Idaho’s notice rules
• File a small claims action in your nearest Idaho County Court if needed

Sample Official Form: Idaho Notice to Landlord

• Form Name: Idaho Answer to Complaint for Eviction Form (Official self-help court form)
  When used: If your landlord tries to evict you after refusing a rent increase, use this to respond in court.
  Where to find: Idaho Court Assistance Office Landlord-Tenant Forms. Find the “Answer to Complaint for Eviction” form.
• How to use: Complete and file the form with the county courthouse listed in your eviction notice within the deadline.

If you need to formally dispute a rent increase, you can reference your signed lease and provide written notice stating you do not consent to the change if the lease does not permit it.

Relevant Government Contacts

• Official Tribunal/Board: Idaho does not have a dedicated landlord-tenant tribunal; housing disputes are generally handled by Idaho State Courts.

Remedies and enforcement options are outlined in the Idaho Landlord and Tenant Act.
