When Can Idaho Landlords Raise Rent for Pass-Through Costs?

Rent Control & Rent Stabilization Idaho published June 21, 2025 Flag of Idaho

Understanding when and how a landlord can raise your rent is a vital part of your rights as a renter in Idaho. Idaho has no statewide rent control, and rules around "pass-through costs" (when a landlord passes increased costs like utilities or property taxes on to tenants) can be confusing. This guide explains your rights, the limits of rent increases, required notice periods, and where to get help in Idaho.

Idaho Law: Rent Increases and Pass-Through Costs

Unlike some states, Idaho does not limit how much a landlord can increase rent for residential properties. However, they must follow legal notice rules. "Pass-through costs" usually refer to additional fees for things like utility increases, property tax hikes, or new service charges that landlords sometimes seek to pass along to tenants. In Idaho, these increases are only allowed if your lease or rental agreement specifically allows it.

  • No Statewide Rent Control: There is no legal limit on the amount or frequency of rent increases in Idaho.[1]
  • What Are Pass-Through Costs? These are extra costs not included in your base rent, such as increased utilities or new service fees. These can only be added if your lease says so.
  • Notice Required: If you rent month-to-month, a landlord must give you at least 30 days’ written notice before raising your rent.[2]

When Can a Landlord Add Pass-Through Charges?

A landlord can only add or increase pass-through costs (like utilities or property tax increases) during your lease if:

  • Your lease or rental agreement mentions the pass-through costs and allows the landlord to adjust the amount
  • You agree in writing to any new charges or adjustment during the tenancy

If your current lease is silent on pass-through charges, your landlord cannot suddenly add new fees or increase your rent without proper notice, or until your lease renews.

Required Legal Notice for Rent Increase in Idaho

  • If you're renting month-to-month, landlords must provide a written notice at least 30 days before the new rate begins.[2]
  • For fixed-term leases (for example, a one-year lease), rent cannot be changed until the lease renews, unless your agreement allows for mid-term increases.

Notice must be delivered in writing. Acceptable methods can include personal delivery, mailing a letter, or another method agreed upon in your lease.

If you receive a rent increase or new pass-through fee and your lease is unclear, ask your landlord for clarification in writing and keep a copy of your communication for your records.

Relevant Idaho Rental Forms & How to Use Them

  • 30-Day Notice of Rent Increase: Idaho law does not provide a state-issued form, but landlords must give written notice at least 30 days in advance for month-to-month tenancies. If you need to respond in writing, use a dated letter or email.
    • Example: Your landlord hands you a letter stating your rent will go up $50 starting next month. As a tenant, you can send your own dated letter asking for clarification if necessary.
    • See more guidance at the Idaho Attorney General's Landlord and Tenant Manual.
  • Small Claims Court Forms: If you disagree with a pass-through cost or feel a rent increase violates your rental agreement, you may file a claim in small claims court (Idaho Court Assistance Office Forms).

Always communicate in writing when disputing a rent increase or pass-through cost, and keep all correspondence for your records.

In Idaho, most rental disputes, including issues with rent increases or pass-through costs, are handled through the local court system. There is no state-specific housing tribunal, but the Idaho Court Assistance Office provides self-help and forms for renters.
