Notice and timing
How delinquency is handled
Grace period after the due date
Bills are due upon presentation and become past due if unpaid within 19 days after the mailing date. Golden State Water allows residential customers a total of 79 days from the mailing date to pay in full before discontinuance, subject to notice, arrangements, health-and-safety protections, and the account’s printed dates. There is no separate universal post-due-date grace period beyond the tariff timeline.
Late-fee calculation
The reviewed 2026 Golden State payment page and tariff do not state one universal percentage late fee for ordinary Claremont residential delinquency. Unpaid bills become delinquent after the 19-day period, and other charges can include the $10 dishonored-check/ACH/electronic-funds-transfer fee, payment-vendor convenience fees, authorized conservation or drought charges, and reconnection fees after a shutoff. The bill and applicable tariff schedule control the actual amount.
Disconnection timeline
For residential service, the bill is due on presentation, delinquency begins after 19 days from mailing, and the company’s policy allows 79 days from mailing before discontinuance. A notice of impending discontinuance must precede shutoff by 7–15 days depending on occupancy type. GSWC avoids Saturdays, Sundays, legal holidays, Fridays, and days before holidays. A payment arrangement can defer discontinuance while the customer remains current; if the arrangement is broken, at least 5 business days’ notice is given.
