Trying to get your misdemeanor case into diversion in San Mateo County? Here is where your case is heard, the county’s diversion options, and how these cases get defended.
The law is statewide; the courts, the DA, and the diversion programs are local — and that local picture shapes the strategy.
Misdemeanor Diversion
Judicial misdemeanor diversion (PC 1001.95) lets a judge divert most misdemeanors — over the DA’s objection — and dismiss the case on completion. It is a statewide statute, so it applies in San Mateo County the same as anywhere in California.
Where Your San Mateo County Case Is Heard
San Mateo County misdemeanor cases are heard at the Hall of Justice, 400 County Center in Redwood City, and at the Northern Branch, 1050 Mission Road in South San Francisco. The exact department and date appear on your citation or arraignment notice.
Cases are prosecuted by the San Mateo County District Attorney’s Office (District Attorney Steve Wagstaffe), at 500 County Center in Redwood City, and custody, when it occurs, is at Maguire Correctional Facility in Redwood City. For the county overview, see our San Mateo County criminal defense page.
San Mateo County Diversion & Collaborative Courts
San Mateo County runs a strong set of collaborative courts that can end a case in treatment and dismissal rather than a conviction:
- a Drug Court for substance-driven cases
- Military Diversion — a pre-plea track for active-duty service members and veterans, operating in San Mateo County since 2016
- a Veterans Treatment Court
- the Pathways Program, the county’s mental-health treatment court, running since 2006
How These Cases Get Defended
- PC 1001.95 reaches most misdemeanors, with statutory carve-outs for domestic violence, offenses requiring sex-offender registration (PC 290), and stalking (PC 646.9). DUI is barred separately by Vehicle Code 23640, not by PC 1001.95 itself.
- Beyond PC 1001.95, mental health diversion (PC 1001.36) and military diversion offer treatment-based dismissals.
- San Mateo County’s collaborative courts add local, structured paths to the same goal: a dismissal.
