California’s 14th Congressional District sits entirely in Alameda County, in the East Bay of the San Francisco Bay Area, and has been represented since 2013 by Democrat Eric Swalwell. It’s one of the state’s most diverse districts, one of its more affluent, and one of the safest Democratic seats in the country.
Cities and Communities in the District
The district runs from bayshore neighborhoods through established suburbs out to the semi-rural Livermore Valley. It takes in the full cities of Hayward, Pleasanton, Livermore, and Union City, plus portions of Dublin, Fremont, and San Leandro.1GovTrack.us. California’s 14th Congressional District Several large unincorporated communities also fall inside its borders, including the census-designated places of Castro Valley, San Lorenzo, and Ashland.
The character of the land shifts as you move east. Near the bay, it’s dense residential and commercial. In the Tri-Valley corridor, technology campuses and federal research facilities dominate. Further east, the Livermore Valley adds a wine region and the tourism that comes with it.

How the Current Boundaries Were Drawn
California’s legislature does not draw congressional maps. Since 2010, that work has belonged to the California Citizens Redistricting Commission, an independent body created by the Voters FIRST Act.11California Citizens Redistricting Commission. We Draw the Lines The commission redraws congressional, state Senate, and state Assembly districts after each decennial census.
The current CA-14 boundaries took effect for the 2022 election cycle, based on 2020 Census data. The next redraw will follow the 2030 Census.
