Notice and timing
How delinquency is handled
Grace period after the due date
No separate grace period applies after the printed due date: San Marcos assesses a late penalty when payment is received after the due date. The published cycle table gives the exact disconnection date, generally 11 days after the due date for cycles 1-3 and 10 days after the due date for cycle 4, subject to weekend/holiday movement. Payment-extension requests must arrive no later than one day before the account's listed disconnection date.
Late-fee calculation
Payments received after the billing-statement due date are assessed a late penalty of 5% of the current balance. The City also lists a $30 NSF check charge. Late penalties continue to apply unless a qualifying arrangement or City-approved assistance addresses them; the payment-assistance page warns that an extended arrangement does not automatically erase a missed due-date penalty.
Disconnection timeline
San Marcos publishes a fixed cycle timeline. Cycle 1: bill on the 16th, due the 3rd of the next month, disconnection on the 14th. Cycle 2: bill on the 24th, due the 11th of the next month, disconnection on the 21st. Cycle 3: bill on the 1st, due the 18th, disconnection on the 28th. Cycle 4: bill on the 8th, due the 25th, disconnection on the 4th of the next month. If due or disconnection falls on a weekend or holiday, it moves forward to the next business day. Payment-extension requests must be received at least one day before disconnection.
