Notice and timing
How delinquency is handled
Grace period after the due date
Five days after the due date before the 10% late fee is added, subject to the published $5 minimum. McKinney also grants a 19-day automatic extension period calculated from the due date, during which a payment expected to arrive may be made without contacting the City; the City does not describe this as a permanent change to the printed due date.
Late-fee calculation
After the five-day grace period, McKinney adds a 10% late fee with a $5 minimum. Customers needing more time must contact Water Billing before the automatic extension ends; a payment plan may be available only when there has been no disconnection or returned payment in the previous six months, is limited to two non-consecutive requests per year, is unavailable for a first bill, and requires 50% payment. A returned payment can also affect eligibility and restoration requirements.
Disconnection timeline
The published timeline is: monthly bill issued; bill due 16 days after the bill date; a five-day grace period follows before the 10%/$5-minimum late fee; a 19-day automatic extension is calculated from the due date; customers needing more time must request a qualifying arrangement before that extension ends. The official public page confirms that accounts can be disconnected after the extension/payment process, but does not publish a single universal calendar day for the physical shutoff visit. Once disconnected, the entire past-due balance, current bill, and related fees are required for restoration.
