• All bills that are not paid on or before their due date are automatically assessed a 10% late fee, without exception, at 8:00am on the first day of the following month, and a late fee will appear on the billing statement.
• Annually, delinquent customer accounts are reported to the SLO County Tax Collector's Office, who collects delinquencies on the District's behalf, assesses additional penalty fees, and places a lien against the property.
