The courthouse handling Menlo Park DUI cases
San Mateo County Superior Court processes all DUI cases arising in Menlo Park. The courthouse is located at 400 County Center in Redwood City — the county seat. Menlo Park sits in San Mateo County, though its position directly on the San Mateo/Santa Clara county line can create occasional ambiguity. The Facebook/Meta campus area straddles the city limits, and defendants should confirm the county of arrest with their attorney. Arraignments for in-custody defendants happen within 3 court days.

The DMV Driver Safety Office for Menlo Park DUI arrests
The South San Francisco Driver Safety Office handles APS (Administrative Per Se) hearings for DUI arrests in San Mateo County, including Menlo Park. The 10-day hearing request deadline runs from the date of arrest. Missing this deadline results in automatic license suspension beginning 30 days after the arrest date. The pink Notice of Suspension given by the arresting officer at the scene serves as your temporary license during that 30-day window. Have an attorney request the hearing on your behalf to avoid waiving any procedural rights.
You have 10 calendar days from your arrest date to request an APS hearing. Missing this deadline means automatic license suspension beginning 30 days after arrest. Contact the South San Francisco Driver Safety Office immediately, or have an attorney request the hearing on your behalf.
MPPD and CHP DUI enforcement in Menlo Park
The Menlo Park Police Department enforces DUI laws on the city’s primary corridors, including El Camino Real, Santa Cruz Avenue, and Sand Hill Road. The California Highway Patrol covers US-101, which runs along the eastern edge of the city and connects Menlo Park to the larger Peninsula freeway network. Sand Hill Road’s venture capital corridor generates a distinct after-work enforcement pattern — the concentration of finance and technology industry gatherings along that stretch produces consistent evening enforcement activity, particularly on weeknights.
San Mateo County prosecution of Menlo Park DUI cases
The San Mateo County District Attorney’s office prosecutes all DUI cases filed in the county, including those arising in Menlo Park. San Mateo County maintains a consistent prosecution posture on DUI cases. First-offense DUI cases with no aggravating factors receive standard plea offers in line with California norms. Wet reckless reductions under Vehicle Code 23103.5 are available for defendants with favorable facts — clean record, BAC near the legal limit, no accident, and defensible stop circumstances — but require active negotiation rather than automatic offer.
After a Menlo Park DUI arrest: your immediate priorities
Request a DMV APS hearing at the South San Francisco Driver Safety Office within 10 days of your arrest to preserve your driving privilege. Your arraignment will be scheduled at San Mateo County Superior Court in Redwood City. Before your arraignment date, consult California DUI counsel to assess the facts of your case. If your arrest occurred near the Facebook/Meta campus or in an area where the county line may be ambiguous, confirm the county of arrest early — it affects both the courthouse and the DMV office.
