County Administration Building

The new 71,000 square foot County Administration Building will be located at 1025 Escobar Street in downtown Martinez.  It will be four stories in size, and house a variety of County departments, and include the Board of Supervisors meeting chamber.  

Parking has always been a challenge near the current, aging McBrien Administration Building.  The new building will have nearby parking for 250 vehicles, including an increase of approximately 75 spaces for the public.  In addition, there will be public plaza areas where the 12-story building now sits at 651 Pine Street.
