Greetings All,
I am wondering if there is a short set of rules for residential stair tread
heights. In a nutshell,
we had a second floor added a couple of years back. The stairs are just
site-built plain old utility grade 2x treads that are held by nails and
construction adhesive. The flooring at both the bottom of said stairs and
top are now finished, so I would like to pretty up the stairway. I know
there are certain dimensions to adhere to pertaining to tread height, depth
and the max variation from tread to tread. Is this something covered by a
national code, or does it vary by municipality? An architect (student) told
me allowable tread height is from 7" to 7 1/2" and no more than 3/32"
variation in tread height over the run of stairs.
I plan on having to remove the 2x treads and hope to use the existing
stringers. I have a thickness planer, so I can pretty much make any
thickness product necessary to conform to code. Thanks to all who are able
to help, Mark
