Autism & housing?

How does a AS diagnosis help regarding housing (if at all?) 

I have been in a rough living situation for about 8 months and before then i was served a non fault S21 which shattered my world after 7 years of being settled in a place. My 'nest' is my safe place and i cannot stand change or the risk of loosing it. It's the foundation of my life and extremely important to me its like an obsession.

Currently i am suffering mentally due to my living situation. So I'm curious now i have an AS diagnosis is it possible to get secure housing or something? What can i get help with or is there nothing?

Thank you
