We have a small mixed-use building with 2 retail units on the ground floor, 3 commercial units on the second floor, and three residential units on the third floor. The residential units are not required to be accessible.
Each residential unit has a door opening onto a private terrace. We'd like to have a 3" step down from the residential units to prevent rain and snow from running from the terrace into the residence.
3" doesn't meet ADA/ICC A117.1 threshold requirements, and it's lower than the 4" minimum tread height for a step. But for some reason, I think it's ok....
Is there anywhere in the code that permits a "weather threshold?"
Or is this a non-issue because the units are not required to be accessible, and the terraces are not a part of the egress path?
