Certain segments of society are easier to house than others. For example, veterans are easier to house than schizophrenics. It's part of the prejudice marginalized people face. There's almost a hierarchy of privilege, even among those who are poor.
In terms of making sure people aren't zoned against or certain groups aren't privileged over others, how would you build a human rights framework around the right for housing, beyond just saying you have a right to a house? Getting the right kind of housing is even more critical than just simply having a roof over your head. How would you make sure funding partners respect that process to make sure people who have dementia aren't treated differently from those who have addictions, are indigenous, or are veterans of the armed forces?
