CSAC Marks Groundbreaking Milestone at Historic 1100 K Street Headquarters

Sacramento, CA – The California State Association of Counties (CSAC) today marked a major milestone in the transformation of its historic headquarters at 1100 K Street, celebrating the completion of the demolition and abatement phase and the transition into construction.

“When counties are stronger, California is stronger,” said CSAC 1st Vice President and Monterey County Supervisor Luis Alejo. “This investment helps ensure that CSAC can continue supporting and representing all 58 counties for generations to come.”

Built in 1911 and listed on Sacramento’s historic registry, the building is undergoing a comprehensive renovation that will preserve key historic features while modernizing the structure to meet current safety, accessibility, and seismic standards.

The project includes restoration of the building’s historic exterior, preservation of signature architectural elements, installation of a new elevator system, construction of a new sixth floor, and creation of modern meeting and communications spaces designed to support CSAC’s statewide mission.

“This is not a demolition,” said CSAC Chief Operating Officer Chastity Benson. “It is a reinvestment. A commitment to a landmark that has been part of the fabric of downtown Sacramento for generations.”

The renovation represents a significant long-term investment in downtown Sacramento and the K Street corridor. Rather than relocate, CSAC chose to reinvest in the century-old landmark and maintain its presence one block from the State Capitol.

Sacramento County Supervisor Rich Desmond, Sacramento City Councilmember Phil Pluckebaum and Downtown Sacramento Partnership Executive Director Michael Ault also participated in the groundbreaking ceremony.

When complete, the renovated headquarters will feature a sixth-floor meeting space overlooking the Capitol and downtown Sacramento, as well as a state-of-the-art media studio that will help California’s counties share innovative solutions and community success stories from across the state.

Construction is expected to continue through late 2027. Throughout the project, CSAC has worked closely with city officials, project partners, and neighboring businesses to minimize impacts and ensure the successful preservation of an important piece of Sacramento’s architectural history.
