- JLC - [1]
- Instead of notching stringers - here is how to use flat stringers, and add the steps as additional pieces. [2]. Expensive for their system, cheap for 3D printed equivalent.
- If you have a point of attachment for risers, these can be built into a wall
- This means that you can avoid stringers in a stairwell, if you fatten up the treads!
- Stringer spacing depends on thickness of treads - 40" stair can use 2 stringers if you use a 4x12 tread [3]
Requirements
- Railing is required: See section R311.7.8.1 of IRC
