* You must right-click on a finished [[floor]] with a [[hammer]], [[mallet]], or [[trowel]] and select '''Build staircase with opening above''' to create a '''planned staircase'''. Be careful not to create one against a wall, at the top or bottom level, as it's impossible to pass. Should you become stuck, the building owner may rotate the staircase to help you exit the confinement.
* Vehicles may not be commanded up staircases, only those that can be dragged can ascend to another floor.
* Animals cannot be ridden up staircases, but may be led.
* Pulling or pushing an object over the opening may send it to an undesired floor.
* You cannot use haul up or haul down with a staircase.
