Idaho: Rent Increase Notice Requirements

Idaho's residential notice rule

Idaho Code § 55-304(2) requires a landlord to provide written notice of a
residential rent increase at least 30 days before the increase is intended to
take effect. That residential rule overrides subsection (1)'s shorter 15-day
month-to-month rule. The notice provision does not prescribe a special form or
list content beyond notice of the increase.

The section was renumbered in 2025. Older sources may cite former § 55-307,
but current § 55-307 now concerns removal of tenant fixtures. The current
increase rule is § 55-304.

Amount, frequency, and fixed terms

Idaho sets no statewide maximum percentage or formula for ordinary residential
rent. Section 55-305(4) expressly says its tenant-fee rules do not limit the
amount that can be charged for rent. The statutes cited here also impose no
separate once-per-year frequency limit.

Section 55-304(2) requires notice for residential leases but does not say
that notice alone overrides the rent promised for a fixed term. For a proposed
mid-term increase, read the lease's rent and adjustment language separately
from the 30-day notice requirement.

Local regulation is preempted by § 55-306. A local governmental unit may
not regulate rent, fees, or deposits charged for leasing private residential
property or force participation in an optional federal housing-assistance
program. The section preserves local control of residential property in which
the governmental unit has a property interest.

Common questions

Is Idaho's notice period 15 or 30 days?

For a residential rent increase, it is at least 30 days under § 55-304(2).
The 15-day rule in subsection (1) is the general month-to-month change-of-terms
rule, and subsection (2) expressly applies notwithstanding subsection (1).

Does Idaho cap the percentage increase?

No. Section 55-305(4) expressly preserves the amount that may be charged as
rent. The 30-day statute controls notice, not price.

Does Idaho state a special penalty for short notice?

Section 55-304 states the written-notice requirement but no special damages
amount or rent-increase-specific penalty. Other contractual or statutory
remedies depend on the facts.
