is there ICF stairs made? i havent found any buy yall would know better... ps inside  like basement to 1st floor and 1st/2nd

I believe its certainly possible with an experienced installer (making them in the field), but from a cost benefit position the benefit would have to be huge! 1st to 2nd floor would be really really expensive and would have to have enough support below to carry the load. I would recommend against it.

Some ideas just aren't worth the time and effort (and expense). This may be one of those.

well i was concerned with the 'fire break' rules in a apartment over a dwelling. and the cement in a ICF floor would meet that ofcourse but whe about stairs.. so i was wondering if there was ICF stairs as well. in my tweak of the oficial plan in the south west corner which the full light high gain exit door will warm the cement also .. but i guess they dont

one small mistake and it would be "cast in concrete" , so to speak

Perhaps you would be better off welding your stairs to the ICF.  Even if you didn't leave them as catilevered you would still have a rock solid stair case.  If you do this start with embeds and them weld your stairs to the wall.  Regards.
