Idaho Rent Increase Notice

What Idaho law says

• AG manual: written notice of a rent increase or change in fees at least 30 days before the increase becomes effective.
• AG manual: Idaho does not restrict the amount of rent or deposits that landlords can charge.
• The manual does not mention rent control.
• The manual says a month-to-month tenancy can be ended by either party with at least a month's advance written notice unless the landlord agrees otherwise.
• The manual lists 55-304 (change in lease terms and notice) in its appendix by title only; the manual page does not tie it directly to the 30-day rule.

Steps for a landlord

• Put the increase in writing with the new amount and effective date.
• Deliver it at least 30 days before the effective date.
• Keep proof of the delivery date.
• Check the lease for any added terms about changes.

What to put in the notice

• The tenants' names and the rental address
• The current rent and the new rent
• The date the new rent starts, after the required notice period
• The date of the notice and how it was delivered
• Your name and signature

Things to watch

• The manual does not say how the notice must be delivered for increases; check the statute.
• The page we read does not address fixed-term leases beyond the lease governing; confirm with the statute or an attorney.
• Cities and counties can add their own rules, including rent control and extra notice requirements. Check your local rules too.
