O Street Project

Location: Corner of 12th and O Street

Summary: This project includes demolition of the existing vacant California Department of Food and Agriculture Annex building, abatement and removal of all asbestos and lead materials, and construction of a new, modern office building at 1215 O Street in Sacramento.

The new building will be approximately 360,000 total gross square feet, and will include office, assembly, storage, building support, parking, and commercial food service space. The building will have an expected building capacity of 1,150 employees and will house staff from the Health and Human Services Agency, the Department of State Hospitals, and the Department of Developmental Services.


  • Sustainable: the building will be Zero Net Energy and is targeting a LEED Platinum certification. The building will also use 60% less water than a typical office building of its size.

  • Inviting: the building, in addition to office space, will have retail, a multi-vendor food court, and will create an attractive pedestrian plaza.

  • Wellness: the building is designed for employee wellness in mind, including having an emphasis on natural daylight, providing clean, filtered outside air, and the use of solar shading to minimize glare and thermal hot spots.
