Free Idaho Rent Increase Notice

▶ Watch overview

Idaho has no rent control and no cap on how much you can raise the rent, but state law fixes the written notice you owe: under Idaho Code 55-304 a month-to-month change of terms needs at least 15 days’ written notice before the month ends, and a residential rent increase or nonrenewal needs at least 30 days’ written notice.

This Idaho Rent Increase Notice raises the rent on a residential tenancy. Idaho sets no rent control and no cap on the amount, but Idaho Code 55-304 requires written notice: a month-to-month change of terms needs at least 15 days’ notice before the month expires, and a residential rent increase or nonrenewal needs at least 30 days’ notice before it takes effect. A fixed-term rent cannot change mid-lease unless the lease allows it. Our how to raise rent guide covers the timing, and the tenant screening laws by state hub helps you place reliable tenants in the first place.

Complete the fields below to generate a Idaho rent increase notice. The new rent and effective date must give the tenant the full statutory notice period. Service should comply with applicable Idaho law; retain proof of service.

An Idaho rent increase notice is the written notice a landlord gives to raise the rent on a residential tenancy. Idaho is a market-rate state: there is no statewide rent control and no statutory cap on how much the rent can go up. Idaho Code 55-304 – the change-in-terms-of-lease notice statute (amended by the 2024 Legislature, ch. 257, and recodified in 2025, ch. 65, from its former number 55-307) – regulates that written notice, while a companion 2025 provision, Idaho Code 55-306, separately bars local governments from enacting any ordinance that would regulate rent, fees, or deposits on private residential property, so a city or county cannot impose a local cap either. What the statute does regulate is the written notice a landlord must give before the rent changes.

The notice turns on the kind of tenancy. For a month-to-month tenancy, Idaho Code 55-304 lets a landlord change the terms of the lease – including raising the rent – upon giving written notice at least fifteen days before the month expires, with the change taking effect at the end of that month. For a residential lease more broadly, the same section requires the landlord to give the tenant written notice of any increase in the rent charged, or of an intent not to renew the lease, at least thirty days before the increase or the nonrenewal is intended to take effect. The practical rule of thumb is simple: a month-to-month change of terms carries a fifteen-day floor, a residential rent increase or nonrenewal carries a thirty-day floor, and when the situation is ambiguous the safer course is to give the longer thirty-day notice. Either way the notice has to be in writing – a verbal increase does not satisfy the statute – and it should state the current rent, the new rent, and the effective date plainly.

A fixed-term lease changes the analysis. While the term runs, the rent is locked at the agreed amount and cannot be raised mid-lease unless the lease itself contains an escalation clause; any increase takes effect at renewal, and the landlord still owes the thirty-day written notice of the new rent or of nonrenewal under 55-304. Mobile-home and manufactured-home communities are governed by a separate statute and a longer clock: under Idaho Code 55-2006, part of the Manufactured Home Residency Act, a landlord may raise lot rent only on ninety days’ written notice, served by first-class mail, certified mail, or personal delivery, with increases kept uniform across the community and made no more than once in any six-month period. That ninety-day rule is specific to manufactured-home lots; it does not apply to an ordinary apartment or single-family rental, and treating it as a blanket statewide rule is a common and costly mistake.

Even without a cap, an increase can still be unlawful because of its motive. Idaho is unusual in that it has no general anti-retaliation statute for ordinary residential tenancies – the express statutory retaliation bar in Idaho Code 55-2015 applies only to manufactured-home parks. For a standard rental, retaliation is instead a common-law defense that Idaho courts have recognized, so a tenant facing an increase that closely follows a good-faith repair request, a complaint to a housing or code authority, or other protected activity may raise retaliation as a defense to an eviction for nonpayment of the increased amount. A cautious landlord avoids timing an increase to a tenant’s protected complaint even though the protection is judge-made rather than codified. Federal and Idaho fair-housing law independently bar an increase aimed at a tenant because of race, color, religion, sex, national origin, familial status, or disability.

Because Idaho sets no required method to serve a general residential rent-increase notice, the practical standard is provable written delivery within the notice period. Personal delivery to the tenant, delivery left at the premises when the tenant is absent, certified mail with a return receipt, or first-class mail all work; email or text is fine only when the lease or tenant authorizes electronic notice and you document it. Whatever the method, the notice should state the current rent, the new rent, and the effective date, and the landlord should keep a signed, dated copy with proof of delivery, allowing extra days for transit when the notice is mailed. Our how to raise rent guide walks through the timing, and screening applicants with verified reports keeps tenancies stable so the increases you serve actually stick.

Put together, a clean Idaho increase is simple but exact: confirm whether the tenancy is month-to-month, a residential lease, or a fixed term; give written notice of at least fifteen days for a month-to-month change of terms or at least thirty days for a residential rent increase or nonrenewal (Idaho Code 55-304); never raise rent mid-term on a fixed lease that does not allow it; keep the ninety-day mobile-home rule (Idaho Code 55-2006) where it belongs; deliver the notice in writing with proof; and never let the increase track a tenant’s protected complaint or a protected class. None of this replaces the screening you do at move-in – a tenant chosen for steady income and a clean payment history is the one most likely to absorb a lawful increase without a dispute.

• No rent control or cap on the amount of an increase; Idaho Code 55-306 also bars local governments from enacting rent control on private residential property.
• At least 15 days’ written notice to change the terms of a month-to-month tenancy, including the rent, before the month expires — Idaho Code 55-304.
• At least 30 days’ written notice of a rent increase or of nonrenewal on a residential lease before it takes effect — Idaho Code 55-304.
• Written notice required — a verbal rent increase does not satisfy 55-304.
• No mid-term increase on a fixed-term lease unless the lease expressly allows it; the increase applies at renewal.
• No discriminatory increase based on a protected class (federal Fair Housing Act and the Idaho Human Rights Act), and courts recognize retaliation as a defense even though Idaho has no general anti-retaliation statute.
• Mobile-home lot rent is separate — Idaho Code 55-2006 requires 90 days’ notice and applies only to manufactured-home communities.

• Idaho sets no required method to serve a general residential rent-increase notice, but Idaho Code 55-304 requires the notice to be written — verbal notice does not satisfy it.
• Personal delivery to the tenant, or delivery left at the rental premises if the tenant is absent.
• Certified mail with a return receipt, or U.S. first-class mail, gives a dated paper trail; allow added days for receipt when you mail.
• Email or text works only if the lease or tenant authorizes electronic notice and you document it; keep the send record either way.

• Giving less than 15 days’ notice on a month-to-month tenancy, or less than 30 days on a residential rent increase or nonrenewal (Idaho Code 55-304).
• Relying on a verbal increase — 55-304 requires written notice.
• Raising the rent mid-term on a fixed-term lease that does not allow it.
• Failing to count added days for receipt when the notice is mailed.
• Timing an increase right after a tenant’s habitability complaint or repair request — Idaho courts recognize retaliation as a defense.
• Applying the 90-day mobile-home rule (Idaho Code 55-2006) to an ordinary apartment or house, or assuming a local rent cap exists — Idaho has none.

• Read the lease first — a fixed term locks the rent until renewal unless the lease has an escalation clause.
• Give written notice: at least 15 days for a month-to-month change, 30 days for a residential increase or nonrenewal, and give the longer period when unsure.
• State the current rent, the new rent, and the effective date plainly, and set the effective date after the notice period runs.
• Deliver by a method you can prove, allow mail-transit days, and avoid timing an increase right after a tenant complaint.

Idaho’s rent-increase notice rule lives in Idaho Code 55-304, titled “Change in terms of lease — Notice.” If you have researched this before, you may know it as Idaho Code 55-307: the Legislature recodified Title 55, Chapter 3 in 2025 (Session Laws ch. 65) and moved the change-of-terms notice rule from 55-307 to 55-304. Today’s 55-307 covers “removal of fixtures by tenant” and has nothing to do with rent, so any form or article still citing 55-307 for a rent increase is pointing at an outdated section number. The primary text is on the Idaho Legislature site.

The two figures you see quoted online — 15 days and 30 days — are both correct, because 55-304 has two subsections that answer two different questions:

• 55-304(1) — 15 days, month-to-month change of terms. On a tenancy from month to month, the landlord “may, upon giving notice in writing at least fifteen (15) days before the expiration of the month, change the terms of the lease to take effect at the expiration of the month.” A rent change is a change of terms, so a bare month-to-month change can ride the 15-day clock, effective at the end of that month.
• 55-304(2) — 30 days, residential rent increase or nonrenewal. “Notwithstanding subsection (1),” in all leases of residential property the landlord “shall provide the tenant written notice of any increase in the amount of rent charged or of the landlord’s intention of nonrenewal of the lease at least thirty (30) days before” the nonrenewal or the increase takes effect. This 30-day residential floor was added by the 2024 Legislature (ch. 257).

Read together, the safe rule is the one this notice follows: for a residential rent increase or a nonrenewal, give at least 30 days’ written notice before the new rent takes effect; a bare month-to-month change of other terms carries a 15-day floor. When the two overlap — a month-to-month tenant receiving a rent increase — the conservative, litigation-proof choice is the longer 30-day notice. Either way the notice must be in writing; Idaho recognizes no verbal rent increase.

No — not statewide, and not locally. Idaho has no statute that caps the amount of a residential rent increase, so a landlord may raise the rent by any amount with proper written notice. In 2025 the Legislature enacted Idaho Code 55-306 (“Local Government — no rent control”), which bars any local governmental unit from enacting, maintaining, or enforcing an ordinance that “would otherwise regulate rent, fees, or deposits charged for leasing private residential property.” That preemption means a city or county cannot impose its own rent cap either.

Idaho cities can still regulate around rent without capping it. The City of Boise, for example, maintains a renter-protection ordinance covering anti-retaliation, source-of-income and other discrimination, application-fee reasonableness, and a tenant rights-and-responsibilities notice — but none of it limits how much or how often a landlord may raise the rent on a market-rate unit. Do not rely on any claim of a local Boise, Moscow, or Sun Valley “rent cap” on private housing; Idaho Code 55-306 forecloses it. The only genuine rate ceilings in Idaho come from a lease you signed (a fixed rent for the term, or a written cap clause) or from a subsidized program — Section 8 Housing Choice Voucher, LIHTC, and public-housing units follow HUD or Idaho Housing and Finance Association rent rules on top of the state notice law.

A rent increase and a fee change ride different Idaho statutes, and the two are easily confused. Base rent is uncapped and follows the 55-304 notice rule. Fees — late fees, pet fees, parking, and similar charges — are governed by Idaho Code 55-305 (“Limitation on fees for tenants of a rental property”), which applies to rental agreements entered into or renewed on or after July 1, 2023. Under 55-305, any fee imposed on a residential tenant “shall be reasonable,” and an owner may not charge a fee, fine, assessment, interest, or other cost greater than the agreement states, or one not in the agreement at all, unless the lease is oral or — for a written lease — “the owner provides the tenant a written thirty (30) day notice of the change in the fee.” Importantly, 55-305 says “nothing in this section shall be construed to limit the amount that can be charged for rent,” so it constrains fees, not the rent figure. If what you are really changing is a monthly fee rather than base rent, use the 30-day fee-change notice under 55-305 and confirm the charge is both reasonable and provided for in the lease.

For an ordinary apartment or single-family rental, Idaho sets no limit on how often rent may be raised — there is no annual cap and no minimum interval between increases. A landlord may raise the rent as frequently as the tenancy type allows, provided each increase carries its own compliant written notice (at least 30 days for a residential increase under Idaho Code 55-304(2)) and none lands mid-term on a fixed lease. The practical brakes are the notice clock and the market: over-frequent or steep increases drive turnover and vacancy, which usually costs more than the increase earns.

The one statutory frequency limit is for manufactured-home lots. Under Idaho Code 55-2006 (Manufactured Home Residency Act), lot rent may be increased only on 90 days’ written notice, increases must be uniform across the community, and the landlord may not amend the rental agreement “more frequently than once in a six (6) month period.” That six-month rule and the 90-day clock apply only to manufactured-home communities — not to a standard apartment or house.

No cap does not mean no limits. Even a properly noticed increase can be attacked on three grounds:

• Discrimination. An increase aimed at a tenant because of race, color, religion, sex, national origin, familial status, or disability violates the federal Fair Housing Act and the Idaho Human Rights Act. Boise and some other Idaho cities add source-of-income and sexual-orientation/gender-identity protections by ordinance.
• Retaliation. Idaho has no general anti-retaliation statute for ordinary residential tenancies — the express statutory bar, Idaho Code 55-2015, protects only residents of manufactured-home communities who complain about a code violation, organize a resident association, or retain counsel. For a standard rental, retaliation is a common-law defense a tenant may raise, and Boise’s ordinance separately bars retaliatory conduct, so a cautious landlord still avoids timing an increase to a tenant’s good-faith repair request or code complaint.
• Unconscionability. A rare, narrow theory: the Idaho Consumer Protection Act’s unconscionability provision, Idaho Code 48-603C, lets a court weigh whether a price “grossly exceeded the price at which similar goods or services were readily available” or whether the deal is “excessively one-sided,” while making clear that “price alone is insufficient” to prove an unconscionable act. It is not a rent cap and rarely succeeds, but a genuinely extreme, targeted increase is not beyond challenge.

What a tenant can do about an increase. Faced with a lawful increase, a tenant’s realistic options are to pay the new rent, negotiate (a longer lease term or a smaller bump), or give notice and move — a tenancy at will ends on at least one month’s written notice under Idaho Code 55-208, and a month-to-month tenant can leave rather than accept the change. A tenant should also check the arithmetic and the calendar: an increase that shorts the 30-day notice, lands mid-term on a fixed lease, or was never put in writing is not yet enforceable for that period. Our how to raise rent guide walks landlords through doing it cleanly the first time.
