San Mateo County Board of Supervisors

Supervisor district lookup and map guidance

Board’s official district map resource (opens in a new tab)Official instructions

The Board page publishes a “Find Your District” section containing an iframe titled “BOS LP Map” from the county GIS district application. This is an information referral to the published map resource; an image label is not treated as a working query. Direct application behavior and an address-specific result were not verified.

Official LAFCO referral to the Board district resource only; other profile figures, meeting information and county-outline imagery are outside this review

The San Mateo County Board of Supervisors is composed of five members elected to four-year terms by the public in their respective districts (see FIND YOUR DISTRICT on the Board of Supervisors website).
