Organize For the Season - Now that you know what's staying in your shed, you must consider when you use the items. You don't want to move a stack of gardening tools just to get to the snow shovels you'll need in the winter. If possible, dedicate one side of the shed to warm-weather specific equipment and the other to cold-weather equipment. This will alleviate any confusion on where items are and save yourself plenty of time when working.
Will Your Outdoor Storage Building Be Big Enough? - Make sure the entry to the unit is wide enough to accommodate your largest piece of equipment, such as a gas snowblower, with room to spare. Many outdoor storage buildings that are at least 8 feet x 10 feet come with double doors, which usually eliminates this concern.
