The notice periods in Idaho

How much warning is required before a higher rent can take effect, and how a fixed lease is treated.

When	Notice in Idaho	What it means
Rent increase or nonrenewal	30 days	At least 30 days written notice before the increase or nonrenewal takes effect, under Idaho Code 55-304.
Other month-to-month lease change	15 days	At least 15 days written notice for a change to a month-to-month lease that is not a rent increase.
Fixed-term lease	None mid-term	During a fixed-term lease the rent is fixed until renewal. The 30-day notice applies to a rent increase or nonrenewal on a month-to-month lease.
Local ordinance	Varies	No local override is available to renters. Idaho Code 55-304 bars a local governmental unit from regulating rent, fees, or deposits for private residential property, and the ban is written into the section heading.
If notice is skipped	Not effective	Idaho gives rent its own longer clock: 15 days for a general terms change, but 30 days for a rent increase. Treating rent increase and nonrenewal alike removes the incentive to dress one up as the other. No city may add a cap, so the 30 days is the ceiling of what a renter gets.

Recent or pending change

Idaho renumbered this chapter in 2025 by ch. 65, so the rent-increase provision is now section 55-304, not 55-307. Section 55-307 today is about removal of fixtures. Anyone quoting 55-307 for a rent increase is citing the wrong section, so confirm the current numbering.

Concrete, neutral steps to check a rent increase in Idaho. This is legal information, not legal advice.

Cite section 55-304, not 55-307
Idaho renumbered the chapter in 2025. The rent-increase provision is now Idaho Code 55-304. Section 55-307 is about removal of fixtures, so quoting it to a landlord in 2026 cites the wrong section.
Know the two clocks
A rent increase or nonrenewal needs 30 days. Any other month-to-month change needs 15 days. So the rent gets the longer notice, which is the figure to hold a landlord to.
Do not expect a city cap
Idaho bars local governments from regulating rent, fees, or deposits, and it is in the section heading. So no Idaho city can cap increases, and the 30 days is the whole of what a renter gets.
Get local help
A local Idaho legal aid office can confirm the current numbering and whether an increase was properly noticed. Search for legal aid in your area.

This is general legal information, not legal advice. Read your own lease and check for a local ordinance, since either can change the notice that applies to your home.

What Idaho renters get wrong

Idaho is unusual in giving rent its own longer clock inside a general terms-change statute. Change the pet rule and a landlord needs fifteen days. Change the rent and they need thirty, under Idaho Code 55-304. Idaho then writes the answer to the follow-up question into the same section, and even into its heading: no local governmental unit may regulate rent, fees, or deposits for private residential property, so the thirty days is the ceiling of what a renter gets and no local ordinance can add to it. The single most concrete correction this research produced is a citation one. Idaho renumbered this chapter in 2025 by chapter 65, so the provision is now section 55-304, not 55-307. Section 55-307 today is about removal of fixtures and has nothing to do with rent. Every commercial guide encountered still cites 55-307, so anyone quoting that section to an Idaho landlord in 2026 is quoting a section about fixtures. Rent increase and nonrenewal are treated alike at thirty days, which removes the incentive to dress one up as the other.

Common questions

Why is the rent notice 30 days and other changes 15 in Idaho?

Idaho Code 55-304 gives rent its own longer clock. A general change to a month-to-month lease needs 15 days, but a rent increase or nonrenewal needs 30 days, so the rent gets the longer notice.

Can Boise cap rent increases in Idaho?

No. Idaho Code 55-304 bars a local governmental unit from regulating rent, fees, or deposits for private residential property, and the ban is in the section heading. So no Idaho city can cap increases.

Does nonrenewal get the same 30 days in Idaho?

Yes. Idaho treats a rent increase and a nonrenewal alike at 30 days, which removes the incentive for a landlord to dress a rent increase up as a nonrenewal to shorten the notice.

Is the Idaho rent-increase citation 55-304 or 55-307?

It is 55-304 since the 2025 renumbering by chapter 65. Section 55-307 is now about removal of fixtures. Most guides still cite 55-307, which is out of date, so use 55-304 for a rent increase.
