You will likely find 10 hour metered parking on the street. These meters take nickels, dimes, and quarters. You may also use the County's public parking structure, which takes quarters only. The meters in the County parking structure allow four hours of parking.


If you are coming from areas north of Redwood City traveling south on Highway 101, take the Whipple Avenue exit. This exit places you on Veterans Blvd. Proceed straight on Veterans Blvd. to Middlefield Road. Middlefield is one short block past the second traffic signal after Whipple Avenue. Turn right onto Middlefield Road, then turn right at the next opportunity, leading to the County's public metered parking structure (which is entered by turning left, and parking on the first floor). The department is located at the building to the south of the parking structure, at 555 County Center.

If you are traveling Highway 280, take the Highway 92 East exit towards the San Mateo Bridge. Take Highway 101 South, then follow the directions from Highway 101 above.
