South Dakota Manufactured Homes Moving
A permit-issuing authority may issue an annual permit which allows the movement on state trunk highways of an oversize permit vehicle consisting of a licensed motorised vehicle towing a manufactured home. The permit vehicle may not exceed a height of 15 feet. The manufactured home, excluding all nonstructural appendages and safety devices, may not exceed a width of 16 feet or a length of 80 feet. The manufactured home, including all nonstructural appendages except for safety devices, may not exceed a width of 16 feet 6 inches or a length of 80 feet 6 inches.
The motorised vehicle towing a manufactured home must be of sufficient size and power to safely handle the movement of the manufactured home and to maintain minimum speeds where posted. At a minimum, manufactured homes over 8 feet wide but not more than 10 feet wide must be towed by a motor vehicle of no less than 6,000 pounds gross vehicle weight rating (GVWR), manufactured homes over 10 feet wide but not more than 12 feet wide must be towed by a motor vehicle of no less than 8,000 pounds GVWR, and manufactured homes over 12 feet wide but not more than 18 feet wide must be towed by a motor vehicle of no less than 9,000 pounds GVWR.
The permit is not valid for movement when the wind velocity exceeds 25 miles per hour. Before moving a permit vehicle, the permit holder must ascertain in a manner satisfactory to the permit holder that no width or height restrictions exist on the route which will prohibit the proposed move.
Unless otherwise specified, the fee for an extended period permit is $60.
