Welcome to the Capitol Annex Project

Welcome to the California Capitol Annex Project. Each year, more than a million visitors converge on their state Capitol to engage with California’s democratic process. The new Capitol Annex building will ensure that every young student, advocate and community member can fully participate, with spaces designed to be open and welcoming to all.

The historic Capitol and new Annex is being designed to expand the public’s access to the legislative process, with modern hearing rooms, more space for visitors and improved access to lawmakers.

The Legislature remains committed to delivering a Capitol Annex that welcomes Californians and expands access to the democratic process for generations to come. As the project moves forward, this website will highlight key milestones and features of the new Annex, offering a closer look at how this space is taking shape as a new home for public engagement at the State Capitol.

The Design Vision

Go behind the design of the new Capitol Annex with our project architects as they share the ideas and inspiration shaping this transformative space. 

More than a building, the new Capitol Annex represents a future where every Californian can see, engage with, and participate in their government. Its design reflects the balance of power, embraces universal accessibility, and preserves the historic treasures that connect us to our past.

Honoring our history. Designing for everyone. Building a more accessible future for California.  Watch the video below to hear the architects’ story behind the design.
