Idaho Landlord-Tenant Laws
Idaho Security deposits
Idaho puts no cap on security deposits, but the landlord must refund the deposit within 21 days after the tenant surrenders the premises — or within a different period the lease fixes, never more than 30 days after surrender.
Idaho Rent increase notice
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.
Idaho Late fees
Idaho has no numeric cap on late fees, but since July 1, 2023 state law requires every fee charged to a residential tenant — late-payment fees included — to be reasonable, and bars landlords from charging any fee, fine, assessment, or interest that exceeds what the rental agreement states or that is not in the agreement at all (Idaho Code § 55-305).
Idaho Entry notice
Idaho has no statute requiring landlords to give any advance notice before entering a rental unit — entry rights come entirely from the lease.
