Cass County, MO Parking Rules: RV & Boat Parking (2026)

Section 400.030(A)(23)(q)(10) of the Zoning Order lists recreational-vehicle and boat storage as a permitted accessory use: 'Storage of not more than one (1) of each of the following types of accessory vehicles shall be allowed within required front, side or rear setback spaces, provided they are located upon a hard surface as defined in the regulations of this Zoning Order. The accessory types are boats, boat trailers, camping trailers, motorized camping units, or vehicles converted to camping uses.' A household may keep one of each category, a boat, a boat trailer, a camping trailer and a motorized camping unit, simultaneously, but not more than one of any single type, and each has to sit on the hard surface the Zoning Order defines rather than bare ground or grass.

The very next item, Section 400.030(A)(23)(q)(11), draws a hard line against treating this as a loophole for larger vehicles: 'Specifically exterior storage or parking for more than a thirty-day period of any commercial vehicle or bus which exceeds a hauling capacity of three (3) tons as rated by the manufacturer shall be prohibited.' So while a personal camper or boat trailer can sit in the setback indefinitely if it's on a hard surface, a heavy commercial vehicle or bus cannot be stored outdoors on a residential lot for more than thirty days.

Because this rule sits inside the general accessory-uses subsection of the Zoning Order, violations, an unauthorized second boat trailer, a camper parked on grass instead of a hard surface, or overstaying commercial-vehicle storage, are enforced the same way as any other zoning violation under Section 400.030(A)(22): notice from the Zoning Enforcement Officer, a ten-day correction window or Compliance Action Plan application, and Circuit Court referral with fines up to $1,000 per day for what remains uncorrected.
