Sonora, CA Parking Rules: Oversized Vehicle Parking (2026)

Unincorporated Tuolumne County has no separate oversized-vehicle parking chapter. Large vehicles - motorhomes, trailers, 'house trailers and movable living quarters of any nature or description' - are explicitly within the definition of 'vehicle' in Section 10.24.010, which prohibits parking them on county roads or rights-of-way in a way that obstructs vehicular traffic. The 72-hour limit of Section 10.24.030 applies to oversized vehicles just as to cars: a vehicle left more than 72 consecutive hours after a posted notice may be removed at the owner's expense. To impose tighter limits on a particular road, the Board of Supervisors may adopt a resolution under Section 10.24.020 restricting stopping, parking, or standing, effective only after signs or markings are conspicuously posted. For weight-based residential restrictions, California Vehicle Code Section 22507.5 allows local authorities to restrict commercial vehicles rated 10,000 pounds GVWR or more in residential districts by ordinance, again only where posted. Narrow mountain roads in the high country can make obstruction the practical constraint on oversized vehicles. General Chapter 10.24 violations are penalized at $35 under Section 10.24.080.
