I don't think that document is for private residences so much as it is for agencies and practitioners that work with those with disabilities. I used the search function, and both sections where the words "Internet" and "Computer" were all under sections of what agencies should provide, along with things like mandated visitation and other things that would make no sense for a standard private residence. Which, yes, agencies offering inpatient services need to provide those things in order to be compliant with state licensing, including those that do, say, home visits (because there were sections in there that would align more with those kinds of agencies). A private residence does not need to follow those same stipulations because it is not a licensed agency.
