You don't seem to understand the difference between zoning and use because your link proves my exact point. A place zoned residential can fall under ADA compliance if the use is commercial. Exactly as that link states. So the first part of your statement "Houses are not commercial establishments" is correct for zoning classification, but you fail on the second half "as such are not covered under the ADA." - a residence operating as a business can be under ADA. My comment "A residential structure can still be required to be ADA compliant dependent on use." - is 100% correct based on the very evidence you supplied. At this point, why dont you just accept that this is a very complex topic and one that just maybe I've spent more time navigating than you.
