SAN MATEO, California — October 23, 2026. This original California58 Local report is based on an identified public agency record. Proposals, meeting notices, campaign material and estimated outcomes are carefully distinguished from decisions and certified results.
What changes October 24?
The City of San Mateo says voting has been underway since October 5, 2026 through the county’s elections facility and vote-by-mail options. The San Mateo County Registration and Elections Division, previously offering weekday early voting, switches to seven-day operations beginning Saturday, October 24. A later wave of four-day vote centers is set to open October 31.
What are typical hours?
The city states that vote centers generally operate 9 a.m. to 5 p.m. through November 2, and on Election Day, November 3, from 7 a.m. until 8 p.m. The city’s voter page explicitly notes that hours can vary by location, so a resident must check their intended vote center individually rather than treating the general window as a guarantee.
Can a ballot be mailed or returned?
The city describes postage-paid vote-by-mail envelopes, official ballot drop boxes and in-person voting as available options. Follow the county instructions for signature, return deadlines and accessible voting. For late registration, ask the county about the applicable California conditional voter registration process at an eligible voting location.
Check your district, too
San Mateo’s district map is available through the city website. A resident may use the county’s address-specific tool to determine which City Council contest appears on their ballot and review citywide Measures H and F.
