This type of move is highly not recommended. Moving sheds without experience or the proper equipment is EXTREMELY dangerous. Sheds and other structures are very heavy. This also applies to under qualified or under equipped moving services. Damage to the structure being relocated or injury is very likely. 9 out of 10 times when structures are attempted to be moved with a skid steer (Bobcat) or tractor with forks, the floor joist are cracked or completely broken. If the structure is being relocated off the property and you are using a tow truck or a car trailer more likely then not the floor joists and the bottom of the structure will be damaged as well as the yard trying to get the structure into place. If your structure is wider than 8 feet 6 inches at its wider point and being moved off the property you will require special oversize load permits and possibly NYS certified escorts.
