Rich:
I really wasn't trying to be 'smart'...
Just offering support and some suggestions for possible 'fine tuning'.
I am (in my State) a 'certified' 'ACCESSIBILTY INSPECTOR'.
We use ANSI 117.1 2003 as our State standard when we design commercial (and some 'residential') buildings for 'accessible' compliance.
That said, HOW or WHEN or IF a building needs to be "ACCESSIBLE" depends upon the Code in one's jurisdiction and whether or not it applies to commercial, residential, or both type buildings.
"ADA" doesn't 'fit' most applications.
Doesn't mean 'ADA' is 'wrong'...just that it does not 'fit'.
Anyhow...do what YOU think best.
I only offered my 2cents worth................ which isn't much..
