LASC to renumber departments

Superior Court of Los Angeles County to Introduce New Department Numbering System at Stanley Mosk Courthouse for Improved Navigation New Department Numbering System Will Formally Be Introduced May 4, 2026; Wayfinding Updates Align With Court’s Strategic Plan to Improve Navigation, Access and User Experience On May 4, 2026, the Superior Court of Los Angeles County will unveil a new department numbering system at the Stanley Mosk Courthouse designed to streamline navigation and enhance the court user experience, Presiding Judge Sergio C. Tapia II announced today. The updated department numbering system is intended to make it easier for court users to locate departments within the courthouse intuitively. Under the new numbering system, the department (or courtroom) number will match the room number, with the first number of each department number corresponding to the floor on which the courtroom is located, providing clearer and more intuitive wayfinding throughout the courthouse. Court users can locate the Stanley Mosk Courthouse’s new renumbering system here on the Court’s website. “This new renumbering system at the Stanley Mosk Courthouse is a practical step toward improving navigation in one of the busiest courthouses in the nation,” Presiding Judge Tapia said. “By making it easier to locate courtrooms and key areas throughout the courthouse, we are enhancing accessibility, increasing efficiency, and improving the overall experience for the public we serve.” As part of the rollout, the Court has created a dedicated webpage on its website with detailed information about the new department numbers at the Stanley Mosk Courthouse. The current department numbering structure reflects the historical unification of municipal and superior courts following the passage of Proposition 220 in 1998. While this approach preserved continuity at the time, department numbers today often do not align logically with courtroom locations, creating confusion for court users. The new department numbers are part of a broader effort to improve wayfinding within the Stanley Mosk Courthouse. In addition to the updated numbering system, the Court has introduced digital displays in front of every courtroom alongside major destinations such as the Self-Help Center and various Clerk’s Offices, featuring dynamic, department-specific information. These displays are designed to help court users more easily locate their destinations and receive real-time updates on courtroom activity. In addition to the Stanley Mosk Courthouse, the Court has also installed digital signage at the Pomona Courthouse, the Compton Courthouse, and the Michael D. Antonovich Antelope Valley Courthouse, with plans to expand the renumbering initiative to all 36 courthouses across Los Angeles County. This initiative aligns with the Court’s 2025–2028 Strategic Plan, which prioritizes expanding access to justice, improving user experience, and supporting operational efficiency for all court users. Additional updates and information will be made available on the Court’s website as the phased rollout continues.
