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.
