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.

There are 8 staircases in the base game of The Sims 2. There are also 10 porch stairs with side railings to match. Porch stairs can be used on uneven terrain at almost any height, though their normal height is the same height as the foundation. Four porch stairs equals the height of one staircase.

A one-level staircase is one square wide and four squares long, which must be left clear both above and below.

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

The Sims: Unleashed, The Sims: Superstar, and The Sims 2: Apartment Life add spiral staircases. They save space, allowing players to build upper floors to smaller houses.

In The Sims, only one Sim at a time can use a staircase. though there are hacked staircases that get around this. It is not unheard of for staircases in The Sims to get "stuck", and become unusable because the game considers them to be in use. The way to fix that is to use the move_objects cheat to delete the stairs, and then to buy new stairs. In The Sims 2, several Sims can use a staircase at the same time, though it appears that there are still some limits.
