Notice and timing
How delinquency is handled
Grace period after the due date
A dedicated this detail was not publicly posted. The reviewed current billing page states that regular late fees and shutoffs are back in effect but does not publish one universal numeric grace period.
Late-fee calculation
A $50 delinquency fee is identified in Durham’s public customer information for an account reaching the scheduled disconnect stage. Other late, returned-payment, and collection fees are governed by the current City fee schedule; the reviewed pages do not state a universal interest percentage.
Disconnection timeline
Durham offers a one-time payment-arrangement extension of 5, 10, or 15 days for eligible residential customers and monthly payment plans for larger balances. If payment is not made before the disconnect date, a $50 delinquency fee can apply and service may be disconnected; the reviewed pages do not give one universal day-count from the original due date.
