Notice and timing
How delinquency is handled
Grace period after the due date
Bills are due upon receipt and become past due if payment is not received within 19 days of the mailing date. The exact mailed bill and CPUC tariff notices control the operative due date; customers should not rely on a postmark when paying near the deadline.
Late-fee calculation
Fontana’s public customer pages explain the 19-day past-due rule but do not expose a single current flat late-fee amount in the reviewed 2026 HTML. CPUC Rule 9, Rule 11, the current bill form, and the applicable tariff govern delinquency charges, returned items, notices, and reconnection. The company’s 2026 regulatory page links these tariff and rule documents, but several PDF links were blocked by the native reader; unresolved exact 2026 late-fee amounts are therefore recorded as not publicly stated rather than inferred.
Disconnection timeline
Day 0 is the mailing date of the monthly bill; payment is due on presentation and the account becomes past due after 19 days. Fontana’s official service and regulatory pages link a staged CPUC notice process with reminder and urgent forms, and the company reports residential discontinuations for inability to pay under California SB 998. The reviewed public HTML does not state one universal day-count from due date to physical shutoff; the exact deadline is stated in the reminder, urgent, and post-disconnection notices. Customers should contact (909) 822-2201 immediately after receiving a notice and use the company’s CAP, critical-care, third-party-notification, or payment-arrangement protections where eligible.
