Kennewick, WA – The Benton County Assessor’s Office is pleased to announce that they have officially moved their Kennewick office from the Justice Center to the Kennewick Annex Building. Their new office will be open Tuesday, April 11.

About the Move

As part of the larger County Justice Center renovations, it was determined that the Assessor’s office would be more effective if located at the Kennewick Annex Building along with the Auditor’s Office and the Treasurer’s Office, located at 5600 W. Canal Drive. All three offices are excited about the move, and are working together to ensure that all visits to the Kennewick Annex are as smooth as possible. Being all at the same location will allow for easier access, faster visits, and a more organized and fluid experience.

This move will keep the current the business hours of the Assessor’s office to be consistent with the Auditor and Treasurer – the building is open 8:30 AM to 4:30 PM, Monday through Friday. The move will not affect the Assessor’s Prosser location as that office will still be located at the Courthouse.
