Caldwell, ID Parking Rules: RV & Boat Parking (2026)

Caldwell City Code section 10-02-05 sets the off-street parking standards that apply to every zoning district, and subsection (3)(N), "Areas Not Designated For Vehicle Parking," is the operative rule for RVs, boats and trailers kept at a house. " That means a homeowner cannot park a camper or boat trailer inside the required front, side or rear setback, nor on bare dirt or grass that was never built out as a parking surface; the vehicle has to sit on an improved surface outside the setback, such as a driveway or a designated parking pad.

The same section's subsection (3)(L) reinforces this for driveways specifically: required off-street parking areas, including driveways, "are to be used for parking only," with storage and other uses prohibited outside limited exceptions for mobile food units or approved temporary/seasonal uses. Subsection (3)(O) separately bars commercial vehicles and trailers from being parked, stored or left unattended in residentially zoned areas, on public or private property, except while engaged in construction or another permitted activity. Enforcement of Chapter 10 (which includes this parking article) runs through Caldwell City Code section 10-03-10: the Planning Director, a designee, or a code compliance officer may enter land to inspect, serve a notice of violation on the responsible person, and pursue corrective action including citations, cease-and-desist orders, or withholding of permits and certificates of occupancy if the violation is not corrected within a reasonable time set by the director.
