Benton County Administration Building

Benton County has completed a three-story administration building at its Kennewick Justice Center campus, 7122 W. Okanogan Place.

The $15 million project has 44,000 square feet and consolidates the county auditor, assessor, commissioners, treasurer and administration from offices in the justice center and at the Canal Street annex. The move frees up space in the secured justice center building for court-related activities in the district and superior courts.

The county describes the new addition to the complex as a modern office that uses natural light in contrast to the midcentury brutalist style of the existing structures, which were built in the 1980s and were designed to maximize space. 

The new building has windows on all sides and a well-lit atrium at its heart.

It does not affect essential services available in Prosser, the official Benton County seat. 

Banlin Construction of Kennewick was the general contractor. 

MMEC Architecture & Interiors of Kennewick was the designer.
