Amador County, CA Parking Rules: Oversized Vehicle Parking (2026)

Unincorporated Amador County does not impose a county-wide rule restricting where large or oversized vehicles may park in residential neighborhoods. The county's heavy-vehicle controls are about travel and weight, not curbside parking. Chapter 10.24 (Weight Restrictions on Vehicles) limits gross weight on specific infrastructure: a ten-thousand-pound cap on certain county bridges, a fourteen-thousand-pound commercial cap on the Carbondale-Plymouth bridge and Williams Road, twenty-thousand-pound caps on several named roads (including New York Ranch, Fiddletown, Jackson Valley, Martin and Lancha Plana), and a fourteen-ton limit on Defender Grade Road and Joyce Road. The chapter's note cites California Vehicle Code Section 35780 et seq., which empowers local authorities to authorize, by permit, the movement of overweight and oversize vehicles. Amador County issues those movement permits through Title 10, Chapter 10.44 (Transportation Permits). For stationary parking of large RVs, trailers and motorhomes on private property, the zoning code (Chapter 19.48) is the operative authority and is described under RV and boat parking. For oversized vehicles on ordinary roads, the California Vehicle Code's size and weight limits (Division 15) apply. Owners planning to move or park a wide, tall or heavy vehicle should confirm whether a county transportation permit is required and check posted weight limits on the route.
