Grand opening of new $65 million Contra Costa County Administration Building celebrated

By Kristi Jourdan, PIO, Contra Costa County
County and city officials celebrated the grand opening of Contra Costa County’s new Administration Building Tuesday morning, July 9, 2024. Located on Pine Street in the heart of downtown Martinez, the three-story cutting-edge office administration building and civic plaza was unveiled on the historic grounds previously occupied by a taller, outdated office tower and a jail dating back to around 1902. Both were demolished to make way for the modern development including the County’s other new administration building across Escobar Street that houses the Board of Supervisors’ Chambers.
Speakers included Board Chair and District 5 Supervisor Federal Glover, District 1 Supervisor John Gioia, District 2 Supervisor Candace Andersen, District 3 Supervisor Diane Burgis and District 4 Supervisor Ken Carlson, Chief Assistant County Administrator Eric Angstadt and Martinez Mayor Brianne Zorn, and representatives of design firm Perkins & Will and Webcor Builders.
The new $65 million building replaced a programmatically obsolete and contextually out of scale office tower and showcases state-of-the-art architecture that harmonizes beautifully with the surrounding historic buildings. It also rejuvenates the public plaza formed by the vacation of a city street within the County administration campus. It embodies sustainability with on-site photovoltaics for high-performance energy use, responsibly sourced finishes, and low embodied carbon materials.
The development significantly enhances community space by adding a new public law library, ground-floor retail spaces, and a parking garage. The plaza also includes street improvements and an advanced stormwater system tailored to the site’s unique groundwater challenges and topography. Internally, the building acts as a hub for several County administrative departments, including the Public Defender, County Sheriff’s Civil Division and the Office of Racial Equity and Social Justice, consolidating essential services under one roof to improve service delivery and enhance community interaction.
The new building marks a significant contribution to Contra Costa County, where modernity meets tradition and community service meets innovation.
