Administration Building to close in early 2021 

King County will close the aging Administration Building to most operations in early 2021, with employees relocating to King Street Center and the Chinook Building when it is safe for them to return to work. 

Executive Constantine will propose decommissioning the Administration Building – which requires significant maintenance and replacement of aging systems – in his 2021-2022 budget address. Existing customer-facing services previously provided at the Administration Building will be co-located at King Street Center. 

The Administration Building closure is part of a comprehensive effort to re-envision how King County can best use its downtown Seattle properties to provide regional services, and will produce significant cost savings by lowering utility and building maintenance costs. It will also allow the County to defer major maintenance on the aging, inefficient building, which opened in 1971.  

While details are still being worked out, employees will be relocated to King Street Center and the Chinook Building when it is safe for employees to return to work, and many will continue to telework in some capacity. Opportunities will be provided for employees to collect personal items from the Administration Building, and prepare necessary items for transportation.  

The skybridge connecting the King County Correctional Facility and the Courthouse, and the first floor of the Administration Building, will likely remain open to ensure access between buildings.  

The County is developing long-term plans for its downtown civic campus that will include recommendations for repurposing the property.  

As plans are finalized over the coming months, further details will be shared with staff to ensure a safe and successful transition to new worksites.
