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

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.
