Sierra County, CA Parking Rules: Oversized Vehicle Parking (2026)

Sierra County Code Chapter 11.12 does not establish a general oversized-vehicle parking restriction (such as a length or weight cap on residential streets), so large vehicles are governed primarily by the California Vehicle Code and posted limits. Under CVC 22500, oversized vehicles, like all vehicles, may not park in crosswalks, on sidewalks, in front of driveways, within 15 feet of fire hydrants, or in posted no-parking areas. Specific county structures carry posted weight or load limits set by ordinance or signage; the Sierra County Code, for example, establishes an emergency weight limit on the Cedar Grove Ravine Bridge, and the County Public Works Department can post additional road-specific restrictions. The County's Winter Parking Guidelines apply to oversized vehicles, RVs, and trailers as well, all of which must be removed from county roads, rights-of-way, shoulders, street ends, and cul-de-sacs during snow removal so the full road width and shoulders are available for snow storage. Where State Highways (such as SR-49, SR-89, SR-70) run through the county, Caltrans and CVC oversize-load permitting rules govern.
