You can store nearly anything, any size, from boxes to bookshelves, Christmas decorations to cars, couches to computers, a few items or the contents from a whole house – as long as it’s not flammable, hazardous, perishable or illegal.
You can’t store living things, perishable goods or anything that could be flammable. Lawnmowers and other gas engines should be drained before you bring them in.
