California Chief Justice to Help Dedicate New Courthouse in Santa Rosa

What:  California Chief Justice Patricia Guerrero will join local judges and staff to officially commemorate the completion of the new Hall of Justice in Santa Rosa. The court expects to officially open the new courthouse for business this summer.

Who:  The ceremony will include remarks by Chief Justice Patricia Guerrero, Presiding Judge Christopher Honigsberg, Judge Shelley Averill, Retired Judge Gary Nadler, Court Executive Officer Robert Oliver, and Judicial Council Administrative Director Shelley Curran

When:  Friday, May 29, 2026, 1:00-3:00pm (includes ceremony, followed by refreshments and courthouse tours)

Where:  New Hall of Justice for Sonoma County, Jury Assembly Room, 625 Administration Drive, Santa Rosa

NOTE: The ceremony is open for the public and media to attend—email jwilcox@sonomacourt.org to RSVP.

Why:  The construction project will provide a new 6-story, 15-courtroom courthouse of approximately 170,000 square feet in the city of Santa Rosa. This new facility will replace the existing court-occupied space in the Sonoma County Hall of Justice and in the attached jail or Main Adult Detention Facility (MADF) at the county administrative complex. The new building includes features and services the court was previously unable to provide due to space restrictions, such as appropriately sized jury assembly and deliberation rooms, courtroom and clerk's office, and other public waiting areas, attorney interview/witness waiting rooms, children's waiting room, area for security entrance screening (for all court users), and in-custody holding facilities.
