Lassen County, CA Parking Rules: Overnight Parking (2026)

Unincorporated Lassen County has not adopted a general overnight on-street parking prohibition in its vehicle code, so simply parking overnight on a county-maintained road is not itself a county offense. The controlling rule is the California Vehicle Code: a vehicle parked on a highway for 72 or more consecutive hours may be removed by the Sheriff under CVC Section 22651(k) where authorized, and CVC Section 22500 continues to bar overnight parking in crosswalks, driveways, sidewalks and other hazardous locations. Caltrans and the Sheriff may also restrict roadside parking during winter operations on state highways. Where overnight stays turn into living in a vehicle or RV on private property, the county's Camping on Private Property Outside Designated Campgrounds Combining District applies: camping (including sleeping in a parked vehicle) is regulated, any RV used for camping must be licensed and readily transportable, and camping beyond 300 days a year requires a use permit. Susanville, the county's only incorporated city, has its own separate snow and parking rules that do not apply to unincorporated areas.
