Full Breakdown

In unincorporated Santa Clara County, streets designated by Board of Supervisors resolution as residential permit parking areas bar vehicles from parking there except those displaying a valid permit issued to a resident of that street. Emergency vehicles, service vehicles making deliveries or repairs, and vehicles displaying valid disabled placards are exempt. A parking permit does not guarantee an on-street space and does not exempt the vehicle from other parking rules. The restrictions only take effect once signs or markings giving notice are posted, and violations are infractions under the California Vehicle Code.

Violations & Fines

Parking without a permit or exemption in a designated residential permit parking area is an infraction under the California Vehicle Code, per Sec. B17-98.
