Sun Prairie, WI Parking Rules: RV & Boat Parking (2026)

060(C) governs exterior storage of recreational vehicles in residential districts, and the code's definition of "recreational vehicle" explicitly folds in boats, snowmobiles, watercraft, travel trailers, pop-up campers and motor homes alongside the more familiar camper. 1, vehicles at or under 22 feet in length and under 10,000 pounds gross weight can be parked and stored outdoors, but a household is capped at four vehicles total outside, and no more than two of those four may be trailers, commercial vehicles or recreational vehicles combined. Storage has to sit on a paved surface, such as a driveway or an adjacent pad with matching surface treatment, and vehicles must park perpendicular to the street except on curved driveways, with a two-foot setback from any sidewalk.

3 prohibits outdoor parking of oversized RVs in residential districts except as seasonal parking, and permits outdoor storage only with an approved conditional use permit. That permit comes with real conditions: only one oversized vehicle may be stored at a time, it must sit in the rear or side yard at least five feet from the property line, on a designated paved pad, and it must be screened from neighboring residential properties and the street with evergreen plantings at least four feet tall at planting, a fence, or a combination of the two.
