How this works in Idaho
Idaho has no fixed late-fee number. Instead, Idaho Code § 55-305 says any fee, including a late fee, must be reasonable and can't exceed what the rental agreement provides. Changing a fee takes 30 days' written notice.
Worked example for Idaho
Say your rental agreement sets a $35 late fee. You can't charge $50 just because a month was especially late, because the fee can't exceed what the agreement provides. If you want to raise it, give the tenant 30 days' written notice of the change.
