How much notice is required to raise the rent in Idaho?

Verified July 11, 2026 All Idaho topics →

Idaho landlords must give at least 30 days' written notice before any rent increase takes effect, in every residential lease including month-to-month tenancies (Idaho Code § 55-304(2)) — the same 30-day written notice applies to a decision not to renew the lease.

The older 15-day notice rule in § 55-304(1) still exists but now covers only other changes to month-to-month lease terms, not rent increases or nonrenewal; that carve-out dates to July 1, 2020. A month-to-month tenancy itself takes one month's written notice to terminate, from either side (§ 55-208). There is no rent control in Idaho, and since 2024 state law expressly preempts local regulation of rent, fees, and deposits alike, including local ordinances that would force landlords into voucher programs.

Frequency limits Not addressed by statute

Notes and caveats

notice_days_month_to_month = 30 is an EXPRESS statute (§ 55-304(2)), not a derivation. STALE TRAPS: (1) many sources still say '15 days to raise rent' — true only before July 1, 2020, when H.B. 594 (2020 ch. 254 § 1, p. 740) added the 30-day residential rent-increase/nonrenewal rule as then-§ 55-307(3); (2) sources citing § 55-307 for these rules are using pre-July-2025 numbering — S.B. 1043 (2025 ch. 65, emergency clause, eff. 7/1/2025) redesignated § 55-307 as § 55-304 and moved the rent-control preemption to standalone § 55-306 with no substantive change. Preemption history: originated 1990 ch. 185 § 1, p. 414 (then limited to 'controlling the amount of rent charged'); expanded by H.B. 545 (2024 ch. 257 § 1, p. 896) to also preempt local regulation of fees and deposits and local mandates to participate in optional federal housing assistance programs (aimed at Boise's source-of-income ordinance). Related fee-change rule: § 55-305(2)(b)(ii) requires 30 days' written notice to change fees under a written agreement. Manufactured-home variance: MHRA § 55-2006 requires 90 days' written notice for lot-rent increases, uniform increases within rent tiers, and limits rental agreement/rule amendments to once per 6 months. frequency_limits null for site-built rentals: verified negative from full-text chapter sweeps.
