Are you talking about full spiral stairs or stairs that make a 90 with winders? We need a little more info.

That is not code compliant. They can't come to a point like that. From the narrow side, the tread must be 9" deep at 12" in,

This guy doesn't care about code. He says it on the other forum. That's why he's here.

Thought it sounded familiar. I answered the same way, so at least I am consistent.

Everyone is familiar with them and building them to code. Problem with you is that you said on the other forum...you're not doing them to code. So why do you keep asking about them?

Because on Contractor Talk forum you said code wasn't an issue and you no one agreed and wouldn't respond. Now you come here and say code is an issue because your not getting any answers.

Good luck.

Move around on that site with the "previous section/ next section" buttons for more info.

One way to do it is frame a series of boxes on top of each other.the straight section can be framed conventionally. Find out what your rise is and do a layout on the wall first.

If you didn't have problems with your head room it would be 13 risers at 7 1/2 inches. I don't know what your run is so I can say there other than code width of the treads.
