Sierra County, CA Parking Rules: RV & Boat Parking (2026)

Sierra County is a high-elevation Sierra Nevada snow county (Downieville, Sierra City, Sierraville, Yuba Pass), and its main constraint on recreational vehicles is winter snow operations rather than a year-round RV ban. The County's official Winter Parking Guidelines state that during snow removal, vehicles cannot be parked on County Roads, the County Right of Way, or State Highways, and that this applies to trailers, boats, RVs, and disabled vehicles, which must be relocated so plow crews can use the pavement, street ends, cul-de-sacs, and shoulders for snow storage. The Guidelines cite Sierra County Code section 11.12.050 and California Vehicle Code section 22510. Sierra County Code 11.28.010 separately makes it a misdemeanor to sleep in any vehicle or trailer on public property or a public way within any unincorporated townsite between 10:00 p.m. and 6:00 a.m. On private property outside a townsite, the County Code does not set a blanket RV-parking time limit; long-term occupancy or storage may trigger zoning or recreational-vehicle standards in the Land Use code.
