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

The entire county is unincorporated, so the County of Mariposa government regulates parking here through Title 10 of the Mariposa County Code (MCC). The county has not adopted a dedicated ordinance restricting recreational vehicles, travel trailers, or boats stored on a person's own private property; storage on private land is instead governed by the county zoning/development code rather than a parking rule. On county-maintained public roads, highways, and rights-of-way, an RV, camp trailer, or boat trailer is treated like any other vehicle: it is subject to MCC 10.08.031 ('Overnight Parking') and to specific no-parking zones designated under MCC 10.08.020 ('Stopping, Parking, or Standing Prohibited Where'). The county's Snow Removal Policy (Resolution RES-2023-627) adds that in areas above 2,500 feet elevation, all trailers and obstructions must be cleared from the right-of-way for the duration of a 'snow removal condition.' Using an RV as a living unit on the street can also trigger the camping rules in MCC Chapter 10.10. Because rules are location-specific, confirm the exact restriction for your road with Public Works.
