Hi,
I need to build stairs in somewhat confined space. I want to be certain of current code requirements in MA before I start. I've heard there were recent (2010?) changes on this. Can somebody please explain what is the min tread depth, max riser height, min stairs width? Also, is it allowed to have a step on the landing, i.e. landing is divided by the extra step that runs diagonally? I know it was common practice on old stairs, but not sure is modern codes allow it.
Thanks in advance!

Call your building department and ask them and see what code they're under. This the IRC code.

Joe's correct, local first. If closed now, check with your State for the latest code revision. Here's another one, only two years old: http://bulk.resource.org/codes.gov/

Be safe, Gary
