Basement Stairs

Meeting Code

You already have stairs to your basement, but now is a good time to make sure they meet code. You'll also want to consider how the basement stairs contribute to the space in terms of looks and convenience. If your steps don't measure up to code or if their location in the basement won't allow you to sensibly arrange the room, you can rebuild them and even relocate them if it would better serve both upper-level and lower-level living areas.

Codes vary for stair configurations and railing shape, so you'll need to talk to your city's building official about these as well. It's also a good idea to talk to an architect or other design professional to make sure the stairway style works well with your other ideas.

Here are 4 stair designs for you to consider:

1. Straight-run stairs take up about 40 square feet of floor space at the lower level.
2. L- or U-shape stairs require more floor area but are a good choice when a straight run is too steep.
3. Spiral stairs are usually only 4-6 feet in diameter, so they take up little floor space. If you consider this option, you'll need another route for moving furniture and other large objects into the basement (such as a walk-out access). Building codes often prohibit spiral stairs leading to rooms larger than 400 square feet.
4. Winder staircases eliminate the need for a landing around a sharp turn.
