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

140 on April 2, 2008, governs where residents may park or store a recreational vehicle in the county's core residential zone districts, R-20, R-10, R-7, PR-1 and PR-2. Subsection A confines RV parking and storage to paved spaces specifically designed to accommodate the vehicle; grass, gravel or dirt parking of an RV is not allowed in these districts. Subsection B requires that storage space be adjacent and connected to the driveway, or, if the RV sits in the rear yard, that the paved pad be permanently connected to the driveway rather than freestanding.

Subsection C then closes the main loophole: storage of an RV directly on the residential driveway itself is prohibited, because a driveway used for RV storage no longer serves its primary function of everyday household parking. The only exception is a corner lot with a second, separate driveway built off the other street frontage specifically for storage, provided that second driveway does not interfere with normal passenger-vehicle parking. Boats and boat trailers fall within the UDO's broader treatment of recreational vehicles for purposes of this section.

4150 sits in Title 400, the UDO, it reaches only unincorporated Jefferson County; Arnold, Festus, De Soto, Hillsboro, Herculaneum and the county's other incorporated cities set their own RV and trailer parking standards.
