Does the IBC allow the old UBC 3306 (c) Exception of 8″ max rise & 9″ min run, for “private stairways serving an occupancy load of less than 10?The design situation is a small retail store (Lubbock, Texas), owner access only, to a second story storage loft…Would appreciate your wisdom – Richard
- Alternating tread devices
- Spiral stairs
- Aisle stairs where the sightlines dictate steeper slope
- R-3 stairs in dwelling units can go to 7.75 inch maximum rise and 10 minimum depth
- Replacement of existing stairs where the space or construction will not allow it
Thanks for the question.
