Full Breakdown
Alameda County Code § 17.52.130 makes it an unauthorized commercial use of land, and a zoning violation, to park a commercial vehicle, truck, or trailer with a manufacturer's gross vehicle weight rating over 10,000 pounds in any residential (R) district, or on an adjacent street, for more than two hours in any 24-hour period. Parking two or more commercial vehicles there at once is also barred outright. This applies only in unincorporated Alameda County, Castro Valley, San Lorenzo, Ashland, Cherryland and similar communities, not inside Oakland, Berkeley, Hayward, or any of the county's incorporated cities, which enforce their own codes.
Violations & Fines
Violators face a fine under § 17.52.170. The sheriff enforces street-parking violations; the building official enforces private-property violations under § 17.52.150 and may enter the premises to investigate.
