Summary
Inside Dorchester County's mapped Special Flood Hazard Areas, a recreational vehicle parked on a lot has to either move within 180 consecutive days or be licensed and ready for highway use, or else it is treated as a manufactured home and must meet the same elevation and permit standards. The rule comes from the county's flood damage prevention ordinance, not the general zoning code.
(6)Recreational vehicles.a.A recreational vehicle is ready for highway use if it is:1.On wheels or jacking system;2.Attached to the site only by quick-disconnect type utilities and security devices; and3.Has no permanently attached additions.b.Recreational vehicles placed on sites shall either be:1.On site for fewer than 180 consecutive days; or2.Be fully licensed and ready for highway use, or meet the development permit and certification requirements of section 18-34, general standards outlined in section 18-51, and manufactured homes standards in subsection 18-52(3) and (4).
Full Breakdown
Section 18-52 of the county's flood damage prevention chapter sets out the specific standards that apply inside any area of special flood hazard, meaning FEMA Zones A, AE, AH, AO, A1-30, V, and VE where base flood elevation data has been established. Subsection (6) singles out recreational vehicles: an RV counts as "ready for highway use" only if it is still on its wheels or jacking system, connected to utilities and security devices only by quick-disconnect fittings, and has no permanently attached additions such as a deck or carport built onto it.
Once parked, an RV in a flood hazard area has to satisfy one of two tests. It can stay on the site for fewer than 180 consecutive days and leave, no permit needed for that short stay. Or, if it is going to remain longer, or is not fully licensed and ready to tow, it has to get a floodplain development permit under Section 18-34 and meet the same general standards in Section 18-51 and the same manufactured-home elevation and anchoring requirements in Section 18-52(3) and (4) that apply to a mobile home on that lot, including elevating the lowest floor at least two feet above the base flood elevation.
This effectively means a resident who wants to keep a boat, travel trailer, or motorhome parked long-term in a flood zone yard either has to keep moving it out every six months or bring it up to the same flood-resistant construction standard as a permanent manufactured home. Outside the mapped flood hazard areas, this specific durational limit does not apply, and county code does not otherwise cap how long a personal RV, trailer, or boat can sit on a residential driveway.
Violations & Fines
Keeping a recreational vehicle in a Special Flood Hazard Area past 180 consecutive days without either moving it or obtaining a floodplain development permit under Section 18-34 is a violation of Chapter 18. The local floodplain administrator can require the RV's removal or bring it into compliance with the manufactured-home elevation standards of Section 18-52(3) and (4), and continued noncompliance can affect the parcel's National Flood Insurance Program standing.
