7-3/4 is the ideal rise. here is info on stairs. check with your local building inspector.

Isn't it 8 1/4" maximum?

Because Florida has so many old people, I have done more 6" rise stairs in the last ten or fifteen years than I can shake a stick at.

Welcome to the Forum!

in commercial structures the minimum riser height is 4-inches. in residential structures there is no minimum riser height. with that said I would never have less than 4-inches due to the fact anything less is a tripping hazard.

I am aware of Mass requirements as being a designer in Mass. here is the riser requirement for residential structures:

2009 IRC Code http://publicecodes.cyberregs.com/ic...9_3_par147.htm

Mass Amendments (changes above requirements) http://www.mass.gov/eopss/docs/dps/i...780-8th-51.pdf

post back with any questions.
