Late fee
A late fee is an extra charge when an assessment installment is not paid by the due date (or by a grace period in the documents). It is not a violation fine. Some declarations set a dollar amount or a percentage. Some states cap late fees or require a waiting period before they can attach. Interest, collection costs, and attorney's fees are often separate line items.
What to check: the due date, any grace period, the late-fee clause in the CC&Rs or a board-adopted collection policy, and whether they applied your payment to the oldest assessment or to a fine first. If the only "late" item is a disputed fine, read your state's fine-and-lien rules. Florida, California, Texas, and Arizona each treat collection of fines differently. Those are examples.
