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

Overnight parking and overnight camping on public roads in unincorporated Mariposa County are governed by the County of Mariposa through Mariposa County Code Chapter 10.08. The specific section is MCC 10.08.031, titled 'Overnight Parking,' which the Board of Supervisors has amended over time. Ordinance 1101 (2013) and Ordinance 1160 (2021) addressed 'Camping and Overnight Parking' under this section, and Ordinance 1192, adopted November 5, 2024, amended Section 10.08.031 ('Overnight Parking') while also creating a new Chapter 10.10 titled 'Unlawful Camping and Obstruction of Public Rights of Way.' Together these provisions distinguish leaving a vehicle parked overnight from using a vehicle or the right-of-way for living or camping. The exact permitted/prohibited hours and locations are set in the codified text and posted locally, so confirm the current wording with the county. Separately, the county's Snow Removal Policy prohibits overnight or any parking on the pavement or road shoulder during a snow-removal condition in areas above 2,500 feet elevation. Because the relevant ordinance scans are images, drivers should verify specifics with Mariposa County Public Works or the Clerk of the Board.
