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

No countywide ordinance prohibiting all overnight street parking in unincorporated Mono County was identified. The practical limits come from the California Vehicle Code and from winter snow operations. Under CVC §22651(k), a peace officer or authorized employee may remove a vehicle left standing on a highway for 72 or more consecutive hours where a local ordinance authorizes removal. Overnight parking on Forest Service or BLM land has separate federal rules and dispersed-camping limits that are not county ordinances. During snow season, vehicles left on county roads can obstruct plows; CVC §22507 gives the County authority to post and enforce parking restrictions, and obstructing vehicles can be towed under CVC §22651(b). Because Mono County is heavy-snow Eastern Sierra country — Public Works maintains 679.26 miles of road and plowing typically starts at about three inches of accumulation — leaving a car on the road overnight during a storm risks both a tow and blocking emergency access. Note: the Town of Mammoth Lakes (the county's only incorporated town) has its own separate winter-parking ordinance that does NOT apply in the unincorporated county.
