About Placer County

County government is local government. It works best when local residents are involved and active.

For county residents who live outside the cities, Placer County is their local government and provides local government services.

For county residents who live in incorporated cities or towns - Auburn, Colfax, Lincoln, Loomis, Rocklin, and Roseville - the county provides many services, including public safety and public health services, in addition to the services provided by the cities.
