Idaho Rent Increase Notice

In Idaho a landlord must give at least 30 days written notice to raise the rent on residential property (Idaho Code Section 55-304). Idaho has no statewide rent cap and prohibits local rent control (Section 55-306), so no ordinance caps the amount. Attorney review available.

Introduction

Idaho treats a rent increase as a special case among lease changes. A landlord may alter most terms of a month-to-month lease on 15 days written notice before the month ends, but Section 55-304 carves out rent: for residential property the landlord must give at least 30 days written notice of any rent increase before it is meant to take effect (Idaho Code Section 55-304(1)-(2)). Idaho recodified these landlord-tenant sections in 2025 (chapter 65), so the current numbers are 55-304 for the notice and 55-306 for local preemption. A rent increase notice is the written notice that carries the new rent, naming the amount and its effective date. Idaho places no cap on how far the rent may go: there is no statewide rent cap, and a local governmental unit may not enact or enforce any ordinance regulating rent, fees, or deposits for private residential property (Section 55-306), so no city or county limits the figure. Section 55-305 adds only that any tenant fees stay reasonable while confirming the fee rules do not cap the rent itself. Rent under a fixed-term lease holds until the term ends unless the lease allows a change; the 30-day notice governs a month-to-month tenancy or a renewal. The notice must be in writing and served on the tenant. DocDraft builds your Idaho rent increase notice from your facts, with attorney review available before you serve it.

Key Things to Know

  1. 1

    An Idaho rent increase notice is a written notice from landlord to tenant raising the rent on a residential tenancy, naming the new monthly rent and the date the increase takes effect.

  2. 2

    For residential property, an Idaho landlord must give written notice of any rent increase at least 30 days before it is meant to take effect (Idaho Code Section 55-304(2)).

  3. 3

    Most other month-to-month term changes take only 15 days written notice before the month ends, but a residential rent increase is the exception and needs the full 30 days (Idaho Code Section 55-304(1)).

  4. 4

    Idaho has no statewide rent cap, so the landlord may set the new amount; Section 55-305 requires any tenant fees to be reasonable but confirms the fee rules do not cap the rent itself.

  5. 5

    Idaho bars local rent regulation, so no city or county ordinance caps an increase (Idaho Code Section 55-306).

  6. 6

    Rent under a fixed-term lease cannot move mid-term unless the lease allows it; the notice governs a month-to-month tenancy or a renewal, and it must be in writing and served on the tenant (Idaho Code Section 55-304).

  7. 7

    A notice short of the 30 days Idaho requires does not take effect on its stated date; the increase is effective only after a proper 30-day period runs.

[DATE]

[TENANT NAME] [RENTAL ADDRESS, UNIT #] [CITY, IDAHO ZIP]

Re: Notice of rent increase for [RENTAL ADDRESS, UNIT #], Idaho

Dear [TENANT NAME]:

This letter is your formal written notice that the monthly rent for the residence you occupy at [RENTAL ADDRESS] in Idaho is being raised. You now hold this property on a month-to-month tenancy at $[CURRENT MONTHLY RENT] per month.

Starting [EFFECTIVE DATE], the monthly rent becomes $[NEW MONTHLY RENT], due on the same day each month and paid the same way as now. That is a change of $[INCREASE AMOUNT] per month.

This notice is issued under Idaho Code Section 55-304. For residential property, an Idaho landlord must give the tenant written notice of any rent increase at least 30 days before it is meant to take effect, and the date above leaves you at least that many days. Most other changes to a month-to-month lease take only 15 days written notice before the month ends, but a residential rent increase is the exception and requires the full 30 days.

Idaho has no statewide rent cap, and Idaho law bars local governments from enacting rent control, so no city or county ordinance limits this increase (Idaho Code Section 55-306). There is no statewide percentage limit on how far the rent may go, so the amount above is set under the rental agreement and this notice, and any separate fees charged to you stay reasonable as Idaho Code Section 55-305 requires.

Every other term of your tenancy stays the same. This notice adjusts only the rent going forward; it leaves your security deposit and all other terms of the rental agreement unchanged, and it does not end your tenancy. You may accept the new rent and stay, talk the amount over with me, or give proper written notice and move before it takes effect. If you think this notice falls short of the 30 days Idaho law requires, write to me so we can go over the dates together. For any question about the new amount or the effective date, reach me at the phone number or email above.

Please update your records so the payment due on or after [EFFECTIVE DATE] reflects the new monthly rent of $[NEW MONTHLY RENT]. If you remain in the property on or after that date, the new rent applies.

Sincerely,

[LANDLORD / PROPERTY OWNER NAME]

Delivery record: This written notice was served on [DATE] by [personal delivery / mail to the address above]. Keep a copy for your records.

Note: This Idaho rent increase notice draws on Idaho Code Section 55-304, which sets the 30-day written notice for a residential rent increase. Idaho has no statewide rent cap and bars local rent control under Section 55-306. For the generic template and other states, see the Rent Increase Notice hub.

Idaho Requirements for Rent Increase Notice

30-Day Notice for a Residential Rent Increase

For residential property, an Idaho landlord must provide the tenant written notice of any increase in the amount of rent charged at least 30 days before the increase is intended to take effect (Idaho Code Section 55-304(2)). The effective date must give the tenant at least that many days, and Idaho does not vary the period by the size of the increase.

No Statewide Rent Cap

Idaho has no statewide rent cap, so a landlord may set the new rent amount, subject to the lease and the notice period. Idaho Code Section 55-305 requires that any fees charged to a residential tenant be reasonable but confirms the fee rules do not limit the amount charged for rent itself.

No Local Rent Control

A local governmental unit in Idaho may not enact, maintain, or enforce an ordinance or resolution that would regulate rent, fees, or deposits charged for leasing private residential property (Idaho Code Section 55-306). No Idaho city or county has a rent-control ordinance that caps the amount of an increase.

15-Day Notice for Other Month-to-Month Terms

A change to other terms of a month-to-month lease may be made on at least 15 days written notice before the expiration of the month (Idaho Code Section 55-304(1)). A residential rent increase is the exception and requires the full 30 days under Section 55-304(2).

No Mid-Lease Increase on a Fixed Term

Rent on a fixed-term lease cannot be raised during the term unless the lease specifically allows it, because the rent is a fixed term of the contract. Idaho Code Section 55-304 governs rent increases on a month-to-month tenancy and at nonrenewal or renewal of a lease.

Written Notice Served on the Tenant

The notice must be in writing and served on the tenant (Idaho Code Section 55-304(1)). Idaho's rent-change statute does not add extra days for service by mail, so the landlord should count the full 30 days from when the written notice reaches the tenant and keep proof of how and when it was served.

What the Notice Must State and Counting the 30 Days

The notice should identify the landlord and tenant, give the rental address, state the current monthly rent and the new monthly rent, and state the effective date, confirming it gives at least the 30 days Section 55-304(2) requires. Count the 30 days from when the notice is served; the increase takes effect only on or after the first day past that period.

A Short Notice Is Not Effective Until 30 Days Run

A rent increase served with less than the required time does not take effect on the stated date. Under Idaho Code Section 55-304(2), the increase is effective only after at least 30 days written notice for residential property has run, and a tenant may continue paying the prior rent until a proper 30-day notice period passes.

Frequently Asked Questions

In Idaho it is a written notice from a landlord raising the rent on a residential tenancy, naming the new monthly rent and the date it takes effect. On a month-to-month tenancy the increase is effective only after the period Idaho Code Section 55-304 requires runs. It does not end the tenancy; it changes one term, the rent, going forward. Rent under a fixed-term lease cannot move mid-term unless the lease allows it.

For residential property, at least 30 days written notice before the increase is meant to take effect (Idaho Code Section 55-304(2)). Most other month-to-month term changes take only 15 days written notice before the month ends, but a residential rent increase needs the full 30 days (Section 55-304(1)). Idaho does not scale the 30-day period to the size of the increase.

No. Idaho has no statewide rent cap, so a landlord may set the new amount, subject to the lease and the notice period. Idaho also bars local rent regulation, so no city or county ordinance caps the increase (Idaho Code Section 55-306). Section 55-305 requires any tenant fees to be reasonable but confirms the fee rules do not cap the rent itself.

Generally no. In Idaho, rent under a fixed-term lease is a set term of the contract, so it cannot move mid-term unless the lease allows it. A rent increase notice governs a month-to-month tenancy, or takes effect when a fixed-term lease renews. On a month-to-month tenancy the landlord may raise the rent with the 30-day written notice Idaho Code Section 55-304(2) requires.

The notice must be in writing and served on the tenant (Idaho Code Section 55-304(1)). Idaho's rent-change statute adds no extra days for mail service, so count the full 30 days from when the notice reaches the tenant. Keeping proof of how and when it was served helps if the increase is later disputed.

An Idaho rent increase notice should name the landlord and tenant, the rental address, the current and new monthly rent, and the effective date. It should confirm the notice gives at least the 30 days Idaho Code Section 55-304(2) requires for a residential rent increase, and state how rent is to be paid. Because Idaho has no statewide or local rent cap, no cap figure needs stating.

No. Idaho Code Section 55-306 bars a local governmental unit from enacting, maintaining, or enforcing an ordinance or resolution that would regulate rent, fees, or deposits charged for leasing private residential property. So no Idaho city or county has a rent-control ordinance capping an increase, and the statewide 30-day notice of Section 55-304 governs.

An Idaho increase served with less than the required time does not take effect on the date stated. Under Idaho Code Section 55-304(2), the increase is effective only after at least 30 days written notice for residential property runs. A tenant may treat a short or improper notice as not yet effective and keep paying the prior rent until a proper 30-day period passes.
