When are bills due?
Bills post between 11th and 13th of each month, and are due the 10th of the following month.
Does the City give a "grace period" for past due balances before interruption of services?
Yes - if you cannot get your bill paid by 10th of each month, a 10% late fee is added the following business day. You have until the 20th of that same month (so an additonal 10 days) to get past due portion paid before account is subject for cutoff 21st of the month.
