Canyon County, ID Parking Rules: RV & Boat Parking (2026)

Canyon County Code § 07-17-33(2)B, part of the Special Developments article of the subdivision ordinance, requires condominium and planned unit developments approved in unincorporated Canyon County, Idaho to provide storage areas for the anticipated needs of boats, campers and trailers. The standard requirement is one adequate storage space for every three living units in a typical residential development, though the Planning and Zoning Commission may reduce that ratio if the developer shows a particular project needs less. This requirement is set at the time the PUD or condominium's site development plan is reviewed, alongside required parking, open space and landscaping plans.

Two other Canyon County provisions touch recreational vehicles without regulating everyday yard parking: § 07-10A-11(1)E limits the temporary placement of a recreational vehicle within a mapped special flood hazard area to fewer than 180 consecutive days and requires it stay fully licensed and ready for highway use, and § 07-15-05(1)C lets a landowner apply for a temporary use permit to reside in an RV outside a licensed RV park for up to 90 days in a calendar year. None of these establish a general limit on parking a boat, RV or trailer in a driveway or side yard on an ordinary single-family lot in unincorporated Canyon County; that gap ends at each incorporated city's boundary, since Caldwell, Nampa and the county's other cities set their own residential parking standards.
