Expanding Community Services

The Sonora Courthouse consolidates operations from two buildings into a modern, secure courthouse for centralized criminal, civil, family, traffic, small claims, juvenile, and probate proceedings. It also enables the court to expand basic services it couldn't provide due to space restrictions. The courthouse has jury assembly space and deliberation rooms, a self-help center, family court mediation, attorney interview/witness waiting rooms, and secure circulation for visitors, judicial officers, and court staff, as well as in-custody holding.
