King County Administration Building

Location and directions

With restrictions about COVID-19 rapidly changing, please check with individual departments to be sure a building is open before you seek in-person service. Also, some downtown buildings are not open to the public due to a project to close the Administration Building and relocate the agencies affected. This project will continue until early 2023.
