Staircase

Staircases are a way to travel between different floors on residential or community lots. In The Sims: House Party there is also the Anti-Heisenberg Teleporter, which serves the same purpose, but has a smaller footprint.

The Sims 2: Open for Business allows players to build elevators to help move Sims between floors.

There are 8 stairs in the base game, The Sims 2. There are also 10 porch stairs. The porch stairs can be used by building a room and build another room over it cover the top room with floor covering. Next make 4 empty spaces, place the porch stairs at the either end of the space. There are side railings to go with each stairs and will only go with the stairs they match.
