Rocklin, CA Parking Rules: Oversized Vehicle Parking (2026)

Unincorporated Placer County's parking code does not publish a stand-alone oversized-vehicle ordinance with a specific length or gross-weight threshold for residential streets. Instead, large vehicles are regulated through several overlapping rules. Commercial vehicles, which includes most large box trucks and rigs, are limited to four consecutive hours on any county highway and cannot re-park within 300 feet within 24 hours under Code Section 10.16.010. Any vehicle, including a large RV, trailer, or rig, may not be parked or stored in a county-highway right-of-way for more than 72 consecutive hours. In the eastern Tahoe Basin (east of Emigrant Gap), oversized vehicles parked on county-maintained roadways between November 1 and May 1 obstruct snowplows and are subject to the snow-area parking ban, with fines of $150, $250, and $450 and towing. The county's parking rules also require tires to be within 18 inches of the curb face, which is difficult for very wide vehicles, and prohibit parking that blocks driveways, intersections, or bus pullouts. On private property, large-vehicle storage is shaped by the Zoning Ordinance (Chapter 17) setback and parking-area standards. Because the county does not publish a single oversized-vehicle size cutoff, drivers of large vehicles should rely on the commercial 4-hour limit, the 72-hour storage limit, and the Tahoe winter ban.
