Summary
In unincorporated Alameda County, residents can petition the Public Works director for a residential permit parking area once a block meets zoning, occupancy and 67% signature thresholds, restricting nonresident on-street parking.
The proposed residential permit parking areas shall include at least six adjacent block fronts and at least eighty (80) percent of the block fronts must be residentially zoned, and at a minimum, seventy-five (75) percent of all on-street parking spaces within the proposed area must be occupied during any two one-hour periods between eight a.m. and six p.m.
Full Breakdown
Alameda County Code § 12.30.040 lets residents of unincorporated communities, Castro Valley, San Lorenzo, Ashland and similar areas, petition for a residential permit parking zone. The proposed area must span at least six adjacent block fronts, be at least 80 percent residentially zoned, and show at least 75 percent on-street occupancy during two one-hour periods between 8 a.m. and 6 p.m. The petition needs signatures from 67 percent of addresses in the area before the director will review it, followed by a public hearing and a board of supervisors resolution. Once posted, nonresident vehicles are restricted to posted time limits unless displaying a permit; incorporated cities in the county run their own separate programs.
Violations & Fines
Parking without a displayed permit in a posted zone is a civil citation, processed under California Vehicle Code § 40200 et seq. by the sheriff's department.
