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

Modoc County's code contains no chapter capping how long a motorhome, travel trailer, or boat may be stored or parked on a private residential lot, and no setback or screening rule specific to RVs. The only RV-related county standard is in the zoning code's off-street parking table (Modoc County Code Section 18.110.040), which requires mobile-home parks to provide "one recreational vehicle parking space for each four units" in addition to 1.5 spaces per unit. For RVs, boats, or trailers left on a public county road or right-of-way, the County relies on the California Vehicle Code: a vehicle (including a trailer or boat trailer) left standing on a highway for 72 or more consecutive hours may be cited and removed under CVC Section 22651(k), and CVC Section 22669 authorizes removal of vehicles reasonably believed abandoned. Because Modoc is a high-elevation snow county, residents storing RVs roadside in winter should also note the abandoned-vehicle abatement program in Modoc County Code Chapter 10.20 if a unit becomes inoperative. Always confirm current rules with the Modoc County Planning Department, since zoning interpretations can change.
