How to apply for General Assistance (San Mateo County)

San Mateo County Human Services Agency (HSA)

Who it's for

San Mateo County General Assistance (GA) is a county-funded cash-aid program that helps adult San Mateo County residents pay for living expenses such as rent and utilities when no other source of assistance is available. For a low-income senior it is mainly a bridge while a Supplemental Security Income (SSI) or Cash Assistance Program for Immigrants (CAPI) claim is pending. To qualify you must be at least 18 years old, have lived in San Mateo County for at least 15 consecutive days, and meet the County's income and resource limits. Apply by phone 1-800-223-8383, in person at any San Mateo County HSA regional office, or by mailing a completed application. Applications are usually processed within 30 days.

The smcgov.org page does not publish the current maximum monthly grant amount; the County determines your specific amount during application.
