Mail, text, and in-person payment instructions
Pay by text
No current Downey pay-by-text keyword or SMS enrollment sequence was published on the reviewed 2026 payment page. The City offers online payment, telephone payment, and checking-account automatic debit.
Mail-in address
For bank bill-pay or the current water remittance address, City of Downey, P.O. Box 511790, Los Angeles, CA 90051-1777, effective September 10, 2025. The older water-bill information page also identifies City of Downey, Dept LA 23221, Pasadena, CA 91185-3221 when the bill coupon is used, so customers should follow the address on the current statement and update bank bill-pay records.
Counters, drop boxes, and office hours
Payments are accepted at the Downey City Hall Cashier counter, 11111 Brookshire Avenue, Downey, California. City Hall/cashier hours are Monday through Friday, 7:30 a.m. to 5:30 p.m.; the City’s 2026 page notes a revised schedule effective July 6 with Monday–Thursday 7:00 a.m. to 6:00 p.m. and Friday closed. A drop box is available to the right of City Hall’s front door for after-hours, weekend, and holiday payments. Automatic debit can be set up from a checking account.
